3 HSC Commands, Utilities, and Control Statements

This chapter contains reference information about HSC and VTCS commands and control statements.

Note:

Control statements that are loaded by an operator command are described along with that command. Other control statements, including those specified in the PARMLIB data set, are described independently.
Certain HSC and VTCS commands are described in the ELS Legacy Interfaces Reference. These commands were introduced in a pre-ELS software release and their functionality has been replaced in ELS. These commands are supported by ELS, however, this support will end in a future release.

ACTIvities

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The ACTIvities command generates a statistical report of library resource loading by volume groups (for example, scratch compared to nonscratch, pass-thru activity, mounts, dismounts, entered, and ejected). This report provides information to help you monitor library resources and usage.

The utility also requires the SMF data for the time period requested (see "SET SMF"). It is assumed that you elect to have cartridge movement SMF records recorded in the time period specified. It is also assumed that the SMF records are in sequence by:

SMF ID
date
time, from earliest to latest.

Duplicate or out of sequence records cause the utility to terminate and to display a message indicating that the SMF records are not sorted. See "Additional Sort Control Cards" for sort statements you can specify to avoid this situation.

Note:

Periodic performance statistics are not available for the SL8500 library. Volume movement statistics, including enter, eject, mount, dismount, and move, are produced for all library types.

Syntax

Figure 3-1 shows ACTIvities command syntax.

Figure 3-1 ACTIvities command syntax

Parameters

As shown in Figure 3-1, the ACTIvities command includes the following parameters:

BEGIN(begin-date or TODAY),begin-time)

optionally, specifies the beginning of the period for the activities analysis.

begin-date or TODAY

the starting date of the analysis.

Specify a date in mm/dd/yy or yyyymmdd format.

When using this format, specify a yy value of 71 or greater to indicate a 20th century (19xx) date. Specify a yy value of 70 or less to indicate a 21st century (20xx) date. To avoid confusion, you are encouraged to use the yyyymmdd date format.
Specify TODAY for the default date.

begin-time

the beginning timeofday (24hour value), expressed in hh:mm:ss format.

The allowable range for begintime and endtime parameters is 00:00:00 to 24:00:00. The default value is 00:00:00.

In each of the following examples, activity reporting begins on October 27, 2008 at midnight:

BEGIN(10/27/08,00:00:00) 
BEGIN(20081027,00:00:00) 
BEGIN(TODAY,00:00:00) 
BEGIN(,00:00:00)

END(end-date or TODAY),end-time)

optionally, specifies the beginning of the period for the activities analysis.

end-date or TODAY

the ending date of the analysis.

Specify a date in mm/dd/yy or yyyymmdd format.

When using this format, specify a yy value of 71 or greater to indicate a 20th century (19xx) date. Specify a yy value of 70 or less to indicate a 21st century (20xx) date. To avoid confusion, you are encouraged to use the yyyymmdd date format.

If begindate is specified, enddate must be in the same format.
Specify TODAY for the default date.

end-time

the ending timeofday (24hour value), expressed in hh:mm:ss format.

The allowable range for begintime and endtime parameters is 00:00:00 to 24:00:00. The default value is 23:59:59.

For example:

END(10/27/08,18:00:00) 
END(20081027,11:30:00) 
END(TODAY,23:29:00) 
END(,23:59:59)

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the ACTIvities JCL:

SLSSMF

SMF data which the utility reports against. This may be a number of data sets concatenated from oldest to newest. This is an off-loaded copy of the active SMF data sets, created by the SMF dump utility IFASMFDP.

The SMF record type defined to HSC is the only SMF record used by ACTIvities. To reduce the ACTIvities run time, use the IFASMFDP utility to create a new SMF data set containing only the SMF record type defined to HSC. The following example can be used to create the HSC only SMF data set:

//jobcard
//SMFCOPY   EXEC PGM=IFASMFDP
//MAN       DD DISP=SHR,DSN=input.smf.data
//DUMPOUT   DD DISP=(NEW,CATLG,DELETE),UNIT=your_esoteric,
//             SPACE=(CYL,(500,500),RLSE),DSN=hsc.only.data
//SYSPRINT  DD SYSOUT=*
//SYSIN     DD *
INDD(MAN,OPTIONS(DUMP))
OUTDD(DUMPOUT,TYPE(your_HSC_SMF_record_number))                                    
.                                                                                  
Note - A DISPLAY CDS command can be issued to find your_HSC_SMF_record_number.

Additional Sort Control Cards

You must specify several additional control cards in the SYSIN portion of the SYELSORT JCL to make sure SMF records are sorted.

//SYSIN DD#
  INCLUDE COND=(6,1,BI,EQ,X'xx')
  SORT FIELDS=(15,4,CH,A,11,4,PD,A,7,4,BI,A)
  SUM FIELDS=NONE

Note:

In the INCLUDE COND statement, the SMF type setting, shown as X'xx above, is supplied by the user. The default setting is FF (SMF type 255).

ACTMVCgn

Interfaces:

SLUADMIN utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC required only when specifying the MVCPOOL parameter

Description

The ACTMVCgn command is an optional command used in a VSM environment with the CDRT facility. ACTMVCgn produces two sets of MVCMAINT statements which are output to two files specified by the SLUSMVON and SLUSMVOF DD statements.

After ACTMVCgn executes:

SLUSMVON contains a set of MVCMAINT statements with the READONLY(ON) keyword.
SLUSMVOF contains a set of MVCMAINT statements with the READONLY(OFF) keyword.

Successful execution of ACTMVCgn results in an equal number of MVCMAINT statements in both SLUSMVON and SLUSMVOF data sets.

Note:

Refer to Oracle's ELS publication ELS Disaster Recovery and Offsite Data Management Guide for examples of use of this utility function.

Syntax

Figure 3-2 shows ACTMVCgn command syntax.

Figure 3-2 ACTMVCgn command syntax

Parameters

As shown in Figure 3-2, the ACTMVCgn command includes the following parameters:

ACS(acs-id)

optionally, specifies an ACS that the CSV-based output is filtered against.

acs-id indicates the two-character ACS id. Blanks are not valid. To specify multiple ACSs, separate each ACS id with a comma. If ACS is not specified, the default is all ACSs.

STORMNGR(stormngr-name)

optionally, specifies a STORMNGR that the CSV-based output is filtered against.

stormngr-name indicates the STORMNGR name. This name can include a maximum of 8 characters. Blanks are not valid. To specify multiple STORMNGR names, separate each name with a comma.

MVCPOOL(mvcpool-name)

optionally, specifies an MVCPOOL that the CSV-based output is filtered against.

mvcpool-name indicates the MVCPOOL name. This name can include a maximum of 13 characters. Blanks are not valid. To specify more than one MVCPOOL, separate each MVCPOOL name with a comma.

Note:

If you specify the MVCPOOL parameter and the HSC subsystem is not active, the utility cannot complete and a return code of 8 is issued.

ALL

optionally, requests that READONLY(ON) and READONLY(OFF) control statements be generated for all non-empty MVCs. If ALL is not specified, READONLY control statements are not generated for full MVCs.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the ACTMVCGN JCL:

SLUSMAUD: Output in the form of SLUADMIN utility control statements to audit selected MVCs. This statement is optional; if it is present, then AUDIT utility control statements are generated for all non-empty MVCs, except for those in EXPORT status.
SLUSMVON: ACTMVCGN output in the form of MVCMAINT utility control statements with the READONLY(ON) keyword.
SLUSMVOF: ACTMVCGN output in the form of MVCMAINT utility control statements with the READONLY(OFF) keyword.

AUDit

Interfaces:

Utility only
Yes, when MVC or VTSS is specified

Subsystem Requirements:

Active HSC/VTCS (AUDit MVC, VTSS, or INVLDMIR)
Active HSC at FULL service level (all others)

Description

The AUDit command performs a volume inventory audit for the following:

ACS or LSM
One or more specified LSMs within an ACS
One or more panels within an LSM
One or more rows within a panel
One or more columns (cells) within a row
One or more VTSSs
One or more MVCs

Optional parameters enable you to do the following:

Update the library control data set to reflect cartridges observed.
Produce a discrepancy list and do not update the control data set.

Syntax

Figure 3-4 shows AUDit command syntax.

Figure 3-4 AUDit command syntax

Parameters (Real Volume Audit)

As shown in Figure 3-4, the AUDit command includes the following parameters:

ALL

optionally, specifies that the total library is to be audited.

ACS(acs-id)

optionally, specifies that only a particular ACS in the library is to be audited.

acs-id indicates a one or two digit hexadecimal ACS identifier.

Note:

If the ACS parameter is specified with no LSM parameters, the audit is performed on all LSMs in the ACS at the same time (multitasking). To audit only certain LSMs within an ACS, you must code the LSM parameter with the LSM or list of LSMs.

Optional Parameters (ALL or ACS)

The following parameters may be specified with either ALL or ACS:

EMPTYCel

optionally, specifies that only empty cells are to be audited. This parameter cannot be used in combination with AUDIt parameter DIAGScan(ONLY).

The main benefit provided by auditing only empty cells is reducing the time required to run an audit.

Note:

Oracle does not recommend running an empty cell audit on an SL8500 library because the time to run the audit is not substantially reduced.

Typically, users may specify this parameter when:

they have entered an LSM and placed new cartridges in empty cells, or
they need to correct cartridge location information for library volumes that have been manually moved to empty cells.

In either case, if APPLy(YES) is specified, the CDS is updated to reflect that these cells are no longer empty.

Caution:

In either case, if APPLy(YES) is specified, the CDS is updated to reflect that these cells are no longer empty.

DIAGScan

optionally, specifies that diagnostic cells are to be scanned. The HSC scans these cells one at a time and displays the contents of each cell in the AUDIt utility report. DIAGScan is mutually exclusive with ROW and COLumn. It can be used in combination with all other AUDIt parameters.

ONLY: specifies that only diagnostic cells should be scanned. This parameter cannot be specified in combination with the EMPTYCel parameter.
ALSO: specifies that diagnostic cells should also be scanned along with the normal AUDIt utility operations.

Note:

Cartridge movement between diagnostic cells and regular storage or CAP cells is not supported by the LMU, so diagnostic cell contents can only be reported.

INTRANs

optionally, specifies that in-transit cartridges in an LSM are to be processed. All in-transit cartridges, except those identified in the note below, are read and ejected as part of an AUDIt utility operation. INTRANs is mutually exclusive with APPLY(NO).

Only the first two cells (columns 0 and 1) in a 9310 playground are accessible to an in-transit audit. Cartridges in other cell positions in a 9310 playground (columns 2 through 5) cannot be ejected by an in-transit operation.
9740 diagnostic cells cannot be scanned by an audit.

APPly

optionally, specifies whether the control data set is updated.

YES: specifies that the Audit operation ejects cartridges with duplicate volume serial numbers, unreadable or illegal external media labels, and/or new cartridges unreadable external labels, and performs corrective actions to the control data set to reflect the physical contents of storage cells. YES is the default.
NO: specifies that a discrepancy listing is produced, and the control data set is not updated.

Optional Parameters (ACS Only)

The following parameters may only be specified with ACS:

LSM(lsm-list)

optionally, specifies that only certain LSMs within the specified ACS are to be audited.

lsm-list is a single LSM number or a list of LSM numbers. An LSM number is a hexadecimal value (00-17). An LSM range is not allowed. If a list is specified, the elements must be separated by blanks or commas, and the entire list enclosed in parentheses.

PANel(panel-list)

optionally, specifies that only certain panels within an LSM are to be audited. If this parameter is specified, the LSM parameter may contain only one LSM number.

panel-list is a single panel or a list of panels. Panel ranges are not allowed. If a list is specified, the elements must be separated by blanks or commas, and the entire list enclosed in parentheses. A panellist element is a one or two digit decimal number, specific to the LSM type. See "Panels" for a list of valid values.

The SL3000 library has static panels numbers starting with the left-most back panel (panel 0) and ending with the right-most front panel (panel 23) on a fully-configured library. The panel numbering starts with the BDM, the only required module (panels 12 and 13), and works outward to the left and to the right.

Panels 0 (CAP panel) and 1 (drive panel) are allowable entries for an SL8500 audit, however, in this case the HSC displays a condition code 0 because it does not find any storage cells on these panels.

ROW(row-list)

optionally, specifies that only certain rows within the specified LSM panel are to be audited. If this parameter is specified, the LSM and PANel parameters may contain only one element.

row-list is a single row or a list of rows. Ranges are not allowed. If a list is specified, the elements must be separated by blanks or commas, and the entire list enclosed in parentheses. A rowlist element is a one or two digit decimal number, and is specific to the LSM type. See "Rows" for a list of valid values.

COLumn(column-list)

optionally, specifies that only certain columns (cells) within an LSM panel row are to be audited. If this parameter is specified, the LSM, PANel, and ROW parameters may contain only one element.

column-list is a single column, or a list of columns. Ranges are not allowed. If a list is specified, the elements must be separated by blanks or commas, and the entire list enclosed in parentheses. A columnlist element is a one or two digit decimal number and is specific to the LSM type. See "Columns" for a list of valid values.

A list of rows cannot be specified if a list of columns is specified.
A list of columns cannot be specified if a list of rows is specified.
All SL3000 columns are numbered 0-5 (left to right).

CAP(cap-id)

optionally, specifies a particular Cartridge Access Port to be used for any required cartridge ejections during the Audit operation.

cap-id identifies one or more CAPs. The format is AA:LL:CC, where AA:LL indicates the LSM id, and CC indicates the CAP. See "CAP Numbers" for a list of valid values.

If a CAP is not specified, a CAP in the identified ACS is selected based on the CAPPref operator command. See "CAPPref" for more information.

MultiACS audits cannot specify the CAP parameter. A CAP is chosen for each ACS based upon CAP preference values.

Parameters (Virtual Volume Audit)

As shown in Figure 3-4, the AUDit command includes the following parameters for a virtual volume audit:

VTSS(vtss-name or vtss-list)

optionally, specifies an audit of one or more VTSSs.

vtss-name or vtss-list indicates the names of one or more VTSSs.

INVLDMIR

optionally, specifies an audit of MVCs with invalid MIRs.

MVC(volser, vol-range, or vol-list)

optionally, specifies an audit of one or more MVCs.

volser, vol-range or vol-list indicates the volser, volser range, or volser list of MVC(s) to be processed.

Parameters (Virtual Volume Audit)

As shown in Figure 3-4, the AUDit command includes the following parameters for a virtual volume audit:

VTSS(vtss-name or vtss-list)

optionally, specifies an audit of one or more VTSSs.

vtss-name or vtss-list indicate the names of one or more VTSSs to be processed.

INVLDMIR

optionally, specifies an audit of MVCs with invalid MIRs.

MVC(volser, vol-range, or vol-list)

optionally, specifies an audit of one or more MVCs.

volser, vol-range or vol-list indicates the volser, volser range, or volser list of MVC(s) to be processed.

Audit Report

An audit report lists the VTVs and MVCs that are different from those listed in the CDS, as shown in Example 3-3. In this example, the report shows all MVCs or VTVs as new entries in the CDS, which is typical of the output of a VTCS audit run after you lost all copies of the CDS, then ran recovery procedures.

Example 3-3 Audit report

For every VTV resident on the VTSS, the VTV volser, size in MB, and Management Class

AUDit Report Messages

For every VTV found on an MVC or VTSS, the audit report lists one of following:

VVVVVV VTV possibly corrupt (Block:BBBBBB)

Explanation: During the audit, an I/O error occurred for VTV VVVVVV at block BBBBBB on the MVC being audited.

VVVVVV VTV not found [ , no MVC copies left ]

Explanation: The audit did not find VTV VVVVVV on the MVC or VTSS being audited. If no MVC copies left appears, no MVCs contain copies of t he VTV.

VVVVVV VTV not found on CDS (Block:BBBBBB)

Explanation: The audit did not find VTV VVVVVV on the MVC or VTSS being audited. If no MVC copies left appears, no MVCs contain copies of t he VTV.

VVVVVV VTV not current (Block:BBBBBB)

Explanation: The audit did not find VTV VVVVVV on the MVC or VTSS being audited. If no MVC copies left appears, no MVCs contain copies of t he VTV.

VVVVVV VTV not current (Block:BBBBBB)

Explanation: The audit did not find VTV VVVVVV on the MVC or VTSS being audited. If no MVC copies left appears, no MVCs contain copies of t he VTV.

VVVVVV VTV not current (Block:BBBBBB)

Explanation: The audit did not find VTV VVVVVV on the MVC or VTSS being audited. If no MVC copies left appears, no MVCs contain copies of t he VTV.

VVVVVV VTV Added as secondary copy (Block:BBBBBB)

Explanation: The audit found the second most current copy of VTV VVVVVV at block BBBBBB of the MVC being audited; the audit added this location to the CDS as the secondary MVC copy of the VTV.

VVVVVV Duplicate copy ignored (Block:BBBBBB)

Explanation: The audit found a duplicate copy of VTV VVVVVV at block BBBBBB and ignored this copy.

VVVVVV Link to old version on MVC MMMMMM removed

Explanation: The audit found a newer version of the VTV and removed the link to the old version from the CDS.

VVVVVV Old VTV version deleted from VTSS SSSSSSSS

Explanation: The audit found an old version of the VTV and deleted it from the VTSS.

VVVVVV Old version of VTV retained [ VTSS SSSSSSSS ]

Explanation: The audit found an old version of the VTV, which is the only copy, and retained this version. If VTSS SSSSSSSS appears, the audit found the VTV on a different VTSS than the one that was audited.

VVVVVV Version older than MVC copies [ VTSS SSSSSSSS ]

Explanation: The audit found a version of the VTV that is older than copies on the MVC. If VTSS SSSSSSSS appears, the audit found the VTV on a different VTSS than the one that was audited.

VVVVVV Newer version of VTV found [ on VTSS SSSSSSSS ]

Explanation: The audit found a newer version of the VTV and updated the CDS with this location. If on VTSS SSSSSSSS appears, the audit found the VTV on a different VTSS than the one that was audited.

VVVVVV VTV discovered [ VTSS SSSSSSSS ]

Explanation: The audit found a current version of the VTV on a VTSS whose location was unexpected and updated the CDS with this location. If on VTSS SSSSSSSS appears, the audit found the VTV on a different VTSS than the one that was audited.

VVVVVV VTV valid [ VTSS SSSSSSSS ]

Explanation: The audit found a valid version of the VTV and updated the CDS with this location. If VTSS SSSSSSSS appears, the audit found the VTV on a different VTSS than the one that was audited.

*** VVVVVV no access to VTSS SSSSSSSS ***

Explanation: The audit found a valid version of the VTV which is on a VTSS that the host cannot access.

MVC MMMMMM STATUS CHANGED FROM EXPORT TO CONSOLIDATE VOLUME

Explanation: The audit discovered current VTVs on an export MVC that was created by export by VTV or Management Class. The audit changed the MVC status from export to consolidate and updated the CDS to add the MVC and its VTVs.

EXPORT MVC MMMMMM IS NOW MADE EMPTY IN THE CDS

Explanation: The audit discovered no current VTVs on an export MVC that was created by export by VTV or Management Class. The audit marked the MVC as empty.

WARNING MVC MMMMMM IS AN OUTPUT MVC FROM AN EXPORT OPERATION - FORCING READONLY

Explanation: The audit forced read-only status on export MVC MMMMMM.

Audit terminated. Unable to determine the position of the end of VTV VVVVVV on MVC MMMMMM

Explanation: VTCS issued an Inventory MVC ECAM request to determine the position and volser of a VTV on the MVC being audited. VTSS indicated, in the ECAM response, that it was unable to determine the position of the end of the VTV. Because VTCS needs that information to determine the position of the next VTV on the MVC (assuming end of tape has not been reached), VTCS had to terminate the audit with RC=8. The MVC is left in Audit status. To resolve the condition, drain the MVC. If you cannot drain the MVC, contact Oracle StorageTek Software Support.

BACKup

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Note:

Backup to tape is not supported.

Description

The BACKup command produces a backup of the library control data set (CDS).

The utility automatically selects the primary CDS copy based on the specified CDS DD statements or the CDS order used by the active HSC on the system.

If you want to back up a single, specific copy of the CDS, you can specify a single DD statement, SLSCNTL, to point to the file you want to back up. In general, however, you should only back up the primary CDS; the HSC RESTORE utility automatically creates the correct number of CDS copies when it executes.

Note:

Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information about using BACKup when copies of the CDS are in different locations.
See "PITCOPY" for information about the PITCOPY command as an alternative to backup.

Syntax

Figure 3-5 shows BACKup command syntax.

Figure 3-5 BACKup command syntax

Parameters

None. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information about using BACKup when copies of the CDS are in different locations.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the BACKup JCL:

SLSBKUP: specifies the created backup data set. The LRECL and BLKSIZE of this data set default to 4096.

CANcel

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The CANcel command stops active and queued processes that use an RTD.

Syntax

Figure 3-6 shows CANcel command syntax.

Figure 3-6 CANcel command syntax

Parameters

As shown in Figure 3-6, the CANcel command includes the following parameters:

ID(process-id)

specifies a process to cancel.

process-id indicates the process ID.

Type

optionally, specifies the type of process to cancel.

ALL: Cancel all processes.
MIGrate: Cancel all migration processes.
RECAll: Cancel all recall processes.
RECLaim: Cancel all reclaim processes.

CAPPref

Interfaces:

Console or PARMLIB
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The CAPPref command assigns a preference value to one or more designated CAPs, and places a CAP into automatic or manual mode.

Several HSC commands and utilities require the use of a CAP and give you the option to either specify the CAP to use, or allow the HSC to automatically select a CAP. When you allow the HSC to make the selection, the CAP is chosen based on availability and the CAP preference value.

Assigning CAP preference values establishes an ordered list of CAPs from which the HSC selects an available CAP with the highest nonzero preference value. A CAP's preference value is zero until it is changed by a CAPPref command. Zero preference CAPs are never automatically selected by the HSC; however, they can be explicitly requested by the user.

Note:

A CAP preference value is only in effect on the host that executes the command.
CAP mode (automatic or manual) is in effect on all hosts system-wide for each CAP; it cannot be set discretely for each host.

Syntax

Figure 3-7 shows CAPPref command syntax.

Figure 3-7 CAPPref command syntax

Parameters

As shown in Figure 3-7, the CAPPref command includes the following parameters:

prefvlue

specifies a preference value which is assigned to all listed CAPs. Preference values are decimal in the range from 0-9.

A CAP with a preference value of 9 has the highest priority and is always selected first when it is available. If two or more available CAPs in an ACS have the highest preference value, the one with the lowest CAPid is selected.

The preference value for a PCAP must be zero. A PCAP is only used when explicitly requested by the user; the HSC does not automatically select a PCAP.

To use the CAPPref command to place a PCAP into AUTO or MANual mode, specify a prefvlue of 0.

lsm-id

identifies an LSM. The format of an lsm-id is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

Note:

If you enter this parameter when there is more than one CAP in the specified LSM, an error message is generated.

cap-id, cap-range, or cap-list

identifies one or more CAPs. The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

Note:

If SL3000 library CAPs are not present, the HSC reports them as ”not installed.” This keeps CAP addresses from changing as new CAPs are added.
SL3000 and SL8500 libraries do not contain a PCAP.

A caprange identifies an inclusive range of multicell CAPs; PCAPs are excluded from the range. The beginning and ending values in a range must be valid CAPids and neither CAPid can specify a PCAP. The rules for specifying ranges apply.

PCAPs must be explicitly specified in the CAPPref command.

Example 1:

00:00:00-00:03:00

In this example, all CAPs in LSMs 00:00, 00:01, 00:02, and 00:03, except PCAPs, are included in this range.

Example 2:

00:00:00-00:03:01

In this example, CAPid 00:00:00 is either a standard CAP or a magazinestyle CAP. CAPid 00:03:01 is a magazinestyle CAP. All CAPs in LSMs 00:01 and 00:02, except PCAPs, are included in this range.

Each caplist element can be either a single CAPid or a CAPid range. The elements in a list must be separated by a comma or a blank, and the entire list must be enclosed in parentheses.

host-id

optionally, specifies that the CAPPRef command is to be performed only if the hostid parameter matches the identifier of the issuing host (the SMF system identifier for both JES2 and JES3).

If CAPPref is issued from PARMLIB and a host-id is specified, the command is executed only by the host with the matching ID.
If CAPPref is issued from PARMLIB and a host-id is not specified, the command is executed by each host that accesses PARMLIB.

Refer to Oracle's ELS publication Managing HSC and VTCS for more information about PARMLIB.

AUTO

optionally, indicates that the specified CAPs are to be placed in automatic mode (referred to as automode). Automode CAPs remain unlocked when not in use. AUTO is the initial setting for a PCAP.

When a CAP is in automode, you can initiate an enter operation without issuing an ENter command. You do this by opening the CAP door, placing one or more cartridges inside, and closing the CAP. The CAP is locked while the enter is being processed; then it is unlocked again.

Automode CAPs can be used for eject processing by either:

specifying the CAPid on an EJect command or EJECt utility, or
assigning a preference value and allowing the HSC to automatically select the CAP

A CAP in automode is locked whenever it is selected for an eject operation, to prevent an enter operation on this CAP until the eject completes.

Note:

HSC termination will be slower with CAPs in automode; especially in a multiplehost environment.

MANual

optionally, indicates that the specified CAP is to be locked when not in use. MANual is the initial setting for all multicartridge CAPs.

AUTO or MANual settings are sent hosttohost using LMU broadcast and the status is preserved in the control data set. For this reason, it is recommended that you not make frequent changes to the CAP mode.

A prefvlue of 0 must be specified when using the CAPPref command to set a PCAP to AUTO or MANual mode.

CDs

Interfaces:

Console or PARMLIB
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The CDs command enables, disables, relocates, or expands a control data set on an active HSC (or, in a multiple-host environment, on all active hosts) without requiring you to stop or substantially disrupt normal tape processes.

Syntax

Figure 3-8 shows CDs command syntax.

Figure 3-8 CDs command syntax

Parameters

As shown in Figure 3-8, the CDs command includes the following parameters:

Enable

allocates and activates any preexisting, renamed, or new CDS specified by the DSn parameter. The CDs Enable command can allocate and activate a CDS residing in a new location, either with a preexisting or a new data set name, when the NEWLoc parameter is specified. MVS catalog services are used to resolve the volume and unit definitions, if the NEWVol or NEWUnit parameters are not specified.

The specified control data set must be named in the CDSDEF control statement in PARMLIB.

DSn(dsn)

specifies the control data set name to allocate for all hosts. dsn indicates the data set name. This parameter is required.

NEWLoc

optionally, indicates that a relocation activity has occurred for the CDS named by the DSn parameter. MVS uses the catalog facility to determine the volume location of the relocated CDS.

NEWVol(volser)

optionally, specifies the volume for a relocated CDS copy. In MVS if the new CDS copy is not cataloged, this parameter is required. If NEWVol is specified, but NEWUnit is not, NEWUnit defaults to SYSALLDA.

volser indicates the volume.

NEWVol is required if the user is executing the command in the HSC VM environment.

NEWUnit(unit-name)

optionally, specifies the unit name for a relocated CDS copy. This parameter defaults to SYSALLDA if it is omitted and NEWVol is specified.

unitname indicates the unit name.

NEWUnit is required if the user is executing the command in the HSC VM environment.

Disable

unallocates (makes inactive) the specified CDS. The CDs Disable command does not disable the last active copy of the control data set.

DSN(dsn): optionally, specifies the control data set name to unallocate for all hosts. dsn indicates the data set name.
Primary: optionally, indicates that the current primary control data set is to be disabled.
SEcndry: optionally, indicates that the current secondary control data set is to be disabled.
STandby: optionally, indicates that the current standby control data set is to be disabled.

EXpand

expands all enabled CDSs to the maximum number of 4096 blocks that can fit in the physical space allocated for the CDS. The maximum number of 4096 blocks is determined by the smallest CDS copy.

CDSCREat

Interfaces:

SLUADMIN utility only
UUI Support: Yes

Subsystem Requirements:

None.

Description

The CDSCREat utility uses a small set of parameters to define the CDS for a tapeless configuration. A tapeless configuration may include VLE hardware but may not include any defined ACSs or real tape drives.

Syntax

Figure 3-9 shows CDSCREat command syntax.

Figure 3-9 CDSCREat command syntax

Parameters

As shown in Figure 3-9, the CDSCREat command includes the following parameters:

HOSTid(hostid-list)

specifies the list of SMF host IDs on which this system can be executed. This parameter is required.

hostid-list indicates one or more host ids. You can specify a maximum of 16 host IDs.

COMPRFX(hh)

optionally, specifies the two-character hexadecimal representation of the command prefix to be used to enter commands to the subsystem. If this parameter is omitted or is set to a null value (40), then you must use the MVS MODIFY command to direct requests to the subsystem, for example, F HSC0,D CDS. See Table 3-14 under the SET COMPRFX command for valid values.

hh indicates the two-character hexadecimal value.

SMF(nnn)

optionally, specifies the SMF ID of statistics data that will be written to the SMF data set.

nnn indicates the SMF ID. The value must be between 128 and 255.

If this parameter is omitted, the value is set to 255.

SCRLABL

optionally, specifies the label type used as the scratch default. Specify one of the following:

SL indicates standardlabeled tape. This is the default if the parameter is omitted.
AL indicates ANSIlabeled tape.
NL indicates nonlabeled tape.
NSL indicates nonstandard labeled tape.

DRVHOST(hostname)

optionally, specifies the host ID that will be used as the "master" value for drive addresses. If drive addresses are different for different hosts, a DRVHOST should be set to allow SMC to map client drive addresses to fixed server drive addresses.

host-name indicates the "master" host id.

TCHNIQE

optionally, specifies the recovery technique (number of CDS copies) that will be created and used by the system.

NONE specifies one CDS copy. This is the default if the parameter is omitted.
SHADOW specifies two CDS copies.
STANDBY specifies three CDS copies.

If this parameter is omitted, the default value is NONE. The CDSCREAT utility validates that the specified (or implied) technique matches the number of CDS DD statements specified.

MAJNAME(name)

optionally, specifies an ENQ/DEQ/RESERVE QNAME. name indicates the a 1-8 character QNAME.

If this parameter is omitted, the default value is STKALSQN.

TAPEPLEX(tapeplex-name)

optionally, specifies a TapePlex name for the HSC/VTCS system. tapeplex-name is a 1-8 character TapePlex name. This must match the SMC TAPEPlex name.

If this parameter is omitted, it is set automatically when SMC initially communicates with HSC/VTCS.

OVRLAYOK

optionally, specifies that the input CDS file(s) may be existing CDS data sets, and that they may be overlaid by the create process. If this parameter is omitted, and any CDS file is an existing CDS file, the CDSCREAT process fails.

Additional JCL Requirements

Execution of this utility requires specification of a DD statement for each CDS copy indicated by the TCHNIQE parameter (or exactly one DD statement if the TCHNIQE parameter is omitted).

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the CDSCREat JCL:

SLSCNTL

specifies the primary CDS.

SLSCNTL2

optionally, specifies the secondary CDS.

If a secondary CDS exists, include this statement so that if a switch occurs and the secondary CDS becomes active, the CDSs can be reordered to maintain database integrity.

SLSSTBY

optionally, specifies the standby CDS.

CDSDAta

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required

Description

The CDSDAta command produces XML output data for library configuration and volume and pool definitions from VOLPARM control statements.

Note:

No text output is produced by this command, so the SLSXML DD statement must be included in the SLUADMIN execution to create output from this command. See "Output Data Set Definition (DD) Statements" for more information.

Syntax

Figure 3-10 shows CDSDAta command syntax.

Figure 3-10 CDSDAta command syntax

Surrounding text describes Figure 3-10 .

Parameters

As shown in Figure 3-10, the CDSDAta command includes the following parameters:

TYPE

specifies the type of CDS data for which output is produced. The TYPE Keyword is positional and therefore optional. One of the listed types must be specified.

VOLPOOL: produces XML data for VOLPARM VOLUME pool definitions.
MVCPOOL: produces XML data for VOLPARM MVC pool definitions.
SCRPOOL: produces XML data for VOLPARM SCRATCH pool definitions.
CDS: produces XML CDS data.
CAP: produces XML CAP data.
LSM: produces XML LSM data.
DRV: produces XML drive data.

TYPE

specifies the type of CDS data for which output is produced. The TYPE Keyword is positional and therefore optional. One of the listed types must be specified.

VOLPOOL produces XML data for VOLPARM VOLUME pool definitions.
MVCPOOL produces XML data for VOLPARM MVC pool definitions.
SCRPOOL produces XML data for VOLPARM SCRATCH pool definitions.
CDS produces XML CDS data.
CAP produces XML CAP data.
LSM produces XML LSM data.
DRV produces XML drive data.

CDSDEF

Interfaces:

PARMLIB only
UUI Support: No

Subsystem Requirements:

None.

Description

The CDSDEF command specifies control data set names, locations, and number of control data sets that you want running. This information is used by HSC during initialization.

CDSDEF is a required command.

Syntax

Figure 3-11 shows CDSDEF command syntax.

Figure 3-11 CDSDEF command syntax

Surrounding text describes Figure 3-11 .

Parameters

As shown in Figure 3-11, the CDSDEF command includes the following parameters:

DSN1(dataset-name)

specifies the primary CDS. dataset-name indicates the name of an HSC control data set.

At least one DSN parameter must be specified, as many as three can be specified. If two data sets are specified, then the volume inventory information on both copies is kept current, and these two data sets are referred to as the primary and the secondary CDS.

If all three are specified, then two copies are kept current and the third data set is a standby CDS which is enabled as the default condition. This standby CDS can be disabled with the DISABLE parameter. In the case where a standby copy of the CDS is being used, you do not need to specify which two of the three CDSs are the primary and secondary copies. The HSC determines, based on last use, which two are the correct copies to use during the initialization of the Control Data Set Services.

,VOL1(volser)

optionally, specifies a volume serial number of the DASD volume where the specified CDS resides. If the data set is not cataloged, this must be specified.

If omitted, volume and unit information is determined from the MVS catalog, and the VOL1 parameter is ignored.

,UNIT1(unit-name)

optionally, specifies the unit parameter in the SVC99 dynamic allocation parameter list. If omitted, SYSALLDA is used.

unit-name can be an IBM-defined generic (for example, 3390), a system-built esoteric (for example, SYSALLDA), a user-defined esoteric, or a specific device number. It is recommended that a general value of SYSALLDA be specified (or defaulted) to allow maximum flexibility and to reduce the need for CDSDEF updates to keep them consistent with the active CDS.

DSN2(dataset-name)

optionally, specifies a secondary CDS. dataset-name indicates the name of an HSC control data set.

,VOL2(volser)

optionally, specifies a volume serial number of the DASD volume where the secondary CDS resides. If the data set is not cataloged, this must be specified.

,UNIT2(unit-name)

optionally, specifies the unit parameter in the SVC99 dynamic allocation parameter list. If omitted, SYSALLDA is used.

DSN3(dataset-name)

optionally, specifies a standby CDS. dataset-name indicates the name of an HSC control data set.

,VOL3(volser)

optionally, specifies a volume serial number of the DASD volume where the standby CDS resides. If the data set is not cataloged, this must be specified.

,UNIT3(unit-name)

optionally, specifies the unit parameter in the SVC99 dynamic allocation parameter list. If omitted, SYSALLDA is used.

,DISABLE

optionally, disables the standby CDS. If this parameter is not specified, the default is to enable the standby CDS at HSC initialization.

If DISABLE is specified, initialization verifies the standby CDS by allocating, opening, and reading the data set. The standby CDS is then closed and deallocated. This process enables manual control over the use of the standby CDS during a control data set switch situation.

If the standby CDS is enabled, the HSC automatically uses it for switching. If it is disabled, it is not used. There is no enable parameter for CDSDEF, as the enable condition is the default.

CLean

Interfaces:

Console or PARMLIB
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The CLean command schedules a cleaning cartridge to be mounted on a library-controlled transport. The specified transport is flagged by the control data set and a cleaning cartridge is mounted prior to the next volume mount.

Syntax

Figure 3-12 shows CLean command syntax.

Figure 3-12 CLean command syntax

Surrounding text describes Figure 3-12 .

Parameters

As shown in Figure 3-12, the CLean command includes the following parameters:

dev-id, dev-range, or dev-list

specifies a device address, range of device addresses, or list of addresses for which cleaning is to be scheduled. Each devlist element can be either a single device address or a range. The elements in a list must be separated by a comma or a blank, and the entire list must be enclosed in parentheses.

host-id: optionally, indicates that cleaning is to be performed for the device address of the specified host (the SMF system identifier for both JES2 and JES3).
IMMED: optionally, specifies that an immediate clean of the device is to be preformed if the drive is idle. This occurs regardless of the MNTD Autocln setting. If the device is not idle then the device is scheduled to be cleaned after the dismount of the volume that is currently mounted.

COMMPath

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The COMMPath command is used in a multiple-host environment to do the following:

Set up a tiered communication service between HSC hosts which can be modified at any time without bringing down the HSC.
Define the hierarchy of methods available to each host for communication with other HSC hosts in the TapePlex.
Establish the current method of communication for an HSC host (or switch from one communication method to another).

In a single host environment, the COMMPath command has no effect.

It is recommended that the COMMPath command which defines the host-to-host communications hierarchy be defined in PARMLIB at startup. After startup, issue the COMMPath command from the console to switch or delete communication paths.

The hierarchy of available HSC host-to-host communication methods listed in order, according to burden on HSC performance, are:

TCP (least burden)
VTAM
LMU
CDS (greatest burden)

TCP and VTAM host-to-host communications are strongly recommended. LMU host-to-host communications method places a greater burden on HSC performance because it competes with library hardware communications. CDS host-to-host communications places the greatest burden on HSC performance because it requires access to the shared CDS.

The COMMPath command updates an in-memory table of definitions for the HSC host that executes the command. This table must contain a list of paths for this host and separate lists for each additional HSC host defined. Therefore, on each HSC host, you must issue the COMMPath command once to define the path itself, once to define the path(s) for a second host, and so on. For example, in a system with hosts A, B, and C:

COMMPATH commands in host A startup PARMLIB:
                COMMPATH HOST(A) VTAMPATH(APPLID1) LMU(00) METHOD(VTAM)
                COMMPATH HOST(B) VTAMPATH(ALLLID2) LMU(00) METHOD(VTAM)
                COMMPATH HOST(C) VTAMPATH(APPLID3) LMU(00) METHOD(VTAM)

COMMPATH commands in host B startup PARMLIB:
                COMMPATH HOST(A) VTAMPATH(APPLID1) LMU(00) METHOD(VTAM)
                COMMPATH HOST(B) VTAMPATH(ALLLID2) LMU(00) METHOD(VTAM)
                COMMPATH HOST(C) VTAMPATH(APPLID3) LMU(00) METHOD(VTAM)

COMMPATH commands in host C startup PARMLIB:
COMMPATH HOST(A) VTAMPATH(APPLID1) LMU(00) METHOD(VTAM)
                COMMPATH HOST(B) VTAMPATH(ALLLID2) LMU(00) METHOD(VTAM)
                COMMPATH HOST(C) VTAMPATH(APPLID3) LMU(00) METHOD(VTAM)

It is recommended that path methods mirror each other. However, in the above example, host C could set its method to LMU while host A and B continue to communicate using VTAM.

If an error occurs during a host-to-host communication, the HSC performs an automatic downward switch to the next lower defined communication method. After this switch is performed, an upward switch can only be performed using the COMMPath command.

If a COMMPath command is not defined for each host in a multiple-host environment, then the missing host's communication method defaults to CDS, which may impose a performance burden on all HSC hosts sharing the CDS. However, if the missing host is infrequently active (for example, a test system) then the additional performance burden would be minimal.

Syntax

Figure 3-13 shows COMMPath command syntax.

Figure 3-13 COMMPath command syntax

Surrounding text describes Figure 3-13 .

Parameters

As shown in Figure 3-13, the COMMPath command includes the following parameters:

HOSTid(host-id)

specifies the host for which the command sets or modifies the parameters. This parameter is required for all COMMpath commands.

host-id indicates the host identifier (the SMF system identifier for both JES2 and JES3).

METHod

optionally, specifies the current method of communications to be used for the specified host. This parameter enables you to switch to a higher, lower, or equivalent (for LMUpath only) level method of communications.

CDS

indicates that communication is to be through the control data set. CDS is the initial setting for HSC hosttohost communications.

LMU

indicates that communication is to be through an LMU.

acs-id indicates the LMUpath definition that is to be the active (or current) LMUpath. If you do not supply an acsid, the first LMUpath specified in the list of LMUpath definitions is made active.

If LMU is specified, the LMUpath parameter must have been specified in a previous command, or it must be included in the same command.

If the LMU method is specified in PARMLIB, the switch from CDS to LMU is delayed until the HSC initializes to the full service level.

If the HSC service level drops to base, LMU communications are switched to CDS. When the full service level is restored, an upward switch to the LMU method requires you to issue another COMMPath command.

VTAM

indicates that communication is to be through a VTAM network.

If VTAM is specified, the VTAMpath parameter must have been specified in a previous command, or it must be included in the same command.

A downward switch from the VTAM method is performed when the VTAM APPLID of the HSC is inactivated, or VTAM is shut down.

TCP

indicates that communications is to be through a TCP/IP network.

A downward switch from the TCP method is performed when a TCP/IP error occurs, or TCP/IP is shut down.

LMUpath(acs-id, acs-range, or acs-list)

specifies one or more LMU paths that can be used for hosttohost communications. An LMU is eligible to be used for hosttohost communications if it is connected to other HSCs sharing a library.

acsid or acsrange or acslist specifies one or more specific LMUs. Each acslist element can be either a single ACSid or an ACSid range. The elements in a list must be separated by a comma or a blank, and the entire list must be enclosed in parentheses.

If more than one eligible LMU is specified, the HSC begins searching for an available communications path beginning with the first acsid in the list. The search continues until a path can be established or the end of the list is reached.

The LMUpath definitions are cumulative; that is, the definitions specified in a command are appended to the current list of definitions. You can insert an LMU path into the current list by specifying the LMU path that you wish to insert, followed by the LMU paths that are to come after it. If a COMMPath command specifies an LMU path that is already defined in the list, the path is removed from its current position and appended to the end of the list as specified in the command.

Note:

For a temporary LMU outage, it may be desirable to delete the LMU's path from the list. When the LMU becomes available again, it may be re-added.

VTAMpath(applid)

optionally, defines the VTAM application to be associated with an HSC host. The specified application name is used in the process of establishing a VTAM connection with other HSCs.

applid indicates the name defined by the VTAM APPL statement for the HSC application.

TCPpath(hostname, ipaddress, or /port)

optionally, defines the host name and port number combination, or IP address (IPv4 or IPv6) and port number combination associated with an HSC host. The specified hostname is resolved into an IPv4 or IPv6 address. The combined IP address and port number combination is used to start a host-to-host TCPPATH server on the associated HSC host.

hostname must be a resolvable host name.

ipaddress must be valid IPv4 or IPv6 format address. If you specify "*", the IP address of the current host (the issuer of the command) is used.

port must be a number between 1 and 65535 and be separated from the hostname, IP address, or "*" by a "/" character with no intervening blanks. If no "/" is found, then the default port number of 58080 is used.

Specify the port number so that it does not conflict with TCP or UDP well known port numbers, or with other applications on this host. When a TCPPATH server is started on this host, it will listen on the specified port number for host-to-host communications from other HSC hosts.

The following are examples of TCPpath definitions:

TCPPATH(10.135.73.101/50090)
TCPPATH(PRODMVS/50090)
TCPPATH(10.135.72.102)
TCPPATH(*/50020)
TCPPATH(*)

DELete

optionally, specifies to delete the definitions specified by either or all of the LMUpath, VTAMpath, or TCPpath parameters associated with the specified HSC host.

If LMU is not the current method, you can delete all LMUpath definitions by specifying the LMUpath keyword without any values.
If the current method is LMU, the LMUpath cannot be deleted.
If the current method is VTAM, the VTAMpath definition cannot be deleted.
If the current method is TCP, the TCPpath definition cannot be deleted.

Note:

Specifying COMMPATH HOSTID(id) METHOD(TCP) on the current host starts the TCPPATH server for that host.
Specifying COMMPATH HOST(id) TCPPATH DELETE on the current host stops the TCPPATH server for that host, as well as deletes the TCPPATH definition.
One host cannot start or stop the TCPPATH server on another host.

CONFIg

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required, and must be down on all hosts when running CONFIG RESET.

Description

The CONFIg command defines or modifies the VSM configuration stored in the HSC CDS. You create a single file that contains the CONFIg command and its input statements.

Note:

The CONFIg GLOBAL statement specifies VTCS global values. This statement is required. See "CONFIg GLOBAL Statement".
Dynamic reclaim requires an H level CDS.

Syntax

Figure 3-14 shows CONFIg command syntax.

Figure 3-14 CONFIg command syntax

Surrounding text describes Figure 3-14 .

Parameters

As shown in Figure 3-14, the CONFIg command includes the following parameters:

RESET

optionally, resets the VSM configuration in the CDS.

Specify RESET when:

Changing the CDS to a lower level.
Adding LOCKSTR=structure-name (through CONFIg GLOBAL) to a CDS that did not previously use LOCKSTR=structure-name.
Removing LOCKSTR=structure-name (through CONFIg GLOBAL) from a CDS.
Removing 32 RTD support (i.e. move from a CDS that supported 32 RTDs to one that doesn't).

Do not specify RESET when:

Changing the CDS from F to G, G to H, or H to I.
Changing lock structure names (for example, going from LOCKSTR=VTCSL1 to LOCKSTR=VTCSL2).
Changing VSM volumes (such as adding VTVs and MVCs). Note that VTV and MVC volumes cannot be removed by RESET or any other VTCS utility. Removal of VTV and MVC volumes requires the definition of a new CDS and the use of MERGEcds.
Changing VSM policies (such as changing AMT values).

Note:

HSC must be down on all hosts when you run CONFIG RESET. The changes you made to RTD definitions take effect when you restart HSC.
Although some changes can be done dynamically by running CONFIG and not restarting HSC/VTCS, there may be additional parameter changes required to use any additional resources.
If you run a CONFIG with RESET, then the status flags are reset and message SLS6746E disappears. If a VTSS was offline when you ran the CONFIG (with RESET), you must remember to audit the VTSS.

CDSLEVEL

optionally, specifies one of the following CDS levels:

V61ABOVE

creates an ”F” level CDS, which provides the following enhancements:

Full VSM4 Support
4 MVC copies
800Mb VTVs
Near Continuous Operations (NCO)
Bi-directional clustering
Improved CDS I/O performance - reduces I/O required to manage virtual scratch subpools

V62ABOVE

creates a ”G” level CDS, which provides the following enhancements:

400Mb/800Mb/2Gb/4gb VTVs
Standard/Large VTV Pages
65000 VTVs per MVC

V71ABOVE

creates an ”H” level CDS, which provides the following enhancements:

Dynamic reclaim
Autonomous device support

NOUPDATE

optionally, specifies that the configuration is checked and any appropriate messages output, but no updates are made to the CDS.

CONFIg CLINK Statement

The CONFIg CLINK statement defines the channel interface between two VTSSs in a Cluster and enables you to define CLINKs on IP interfaces to support replication of VTVs over IP CLINKs.

The VTSSs can be in one of three modes:

Primary-Secondary, in which there are two VTSSs and you write CLINK statements for only the Primary.
Peer-to-Peer, in which case there are two VTSSs and you write CLINK statements for both VTSSs to enable bi-directional VTV replication.
Any-to-Any, in which there are more than two VTSSs in the cluster and the individual relationships are defined through CLINK statements.

In addition, CLINKs can be defined from the VTSS to perform electronic export to another TapePlex. These links need not be to the same VTSS within the remote TapePlex.

Each VTSS can either be connected to a maximum of three different TapePlexes, or two TapePlexes and a partner VTSS in a cluster.

An electronic export connection can always be to multiple VTSSs. A cluster connection can be to multiple VTSSs only if the CONFIg CLUSTER statement specifies more than two VTSS members.

Refer to Oracle's ELS publication ELS Disaster Recovery and Offsite Data Management Guide for examples.

Syntax

Figure 3-15 shows CONFIg CLINK statement syntax.

Figure 3-15 CONFIg CLINK statement syntax

Surrounding text describes Figure 3-15 .

Parameters

As shown in Figure 3-15, the CONFIg CLINK statement includes the following parameters:

VTSS=name

optionally, specifies the name of the VTCS that owns the CLINK. This is the VTSS from which the VTVs are replicated or exported.

If this parameter is omitted, by default, the CLINK is attached to the current VTSS being defined.

The VTSS name that you specify on a CLINK statement must be known to VTCS. That is, the VTSS name must be already defined in the CDS or it must be specified in a VTSS statement that already exists in the current set of CONFIG statements. For example, the following is valid:

VTSSNAME=VTSS1 LOW=70 HIGH=80 MAXMIG=3 RETAIN=5 CLINK VTSS=VTSS1 CHANIF=0A

The following is not valid unless VTSS1 is already defined in the CDS:

CLINK VTSS=VTSS1 CHANIF=0A VTSSNAME=VTSS1 LOW=70 HIGH=80 MAXMIG=3 RETAIN=5

CHANIF=ci or ci:p

specifies the channel interface on the VTSS that communicates with the RTD where:

c indicates the VTSS Storage Cluster number (0 or 1).
i indicates the interface number (A, C, E, G, I, K, M, or O)
p indicates the device number on the interface (0, 1, 2, or 3).

For a VSM 5, this value must match the actual FICON interface values. For a VSM 6, this must be unique for each VTSS, and does not correspond to an actual value on the VSM 6 FICON ports.

Regardless of whether the Maximum 32 RTDs feature is enabled, if you do not have greater than 16 RTDs attached to a VTSS, you can use the ”old” addressing scheme (CHANIF=ci).

If, however, the Maximum 32 RTDs feature is enabled and you have greater than 16 RTDs attached to a VTSS, you must use the ”new” addressing scheme (CHANIF=ci:p).

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

IPIF=ci:p

optionally, enables Ethernet connection of two Native IP (IFF3 card) ports, where the ci:p values are shown in parentheses before each Target IP Address on the IFF IP Configuration Status screen for each IFF ethernet port. Valid values for c:ip are:

c indicates the VTSS Storage Cluster number (0 or 1).
i indicates the interface number (A or I)
p indicates the device number on the interface (0, 1, 2, or 3).

For VSM5s, this value must match the value specified on the VSM5 IFF Configuration Status Screen. For VSM 6s, this must be unique for each VTSS; and does not correspond to an actual value on the VSM 6 TCP/IP ports.

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

Note:

The CLINK statement must contain either the CHANIF or IPIF parameter, but not both.

REMPlex=name

optionally, specifies the name of the TapePlex at the receiving end of the CLINK that receives the copies of the VTVs. During validation of the link, this name is compared with the THISPLEX definition in the remote system configuration.

The REMPlex parameter indicates that the CLINK is to be used for electronic export. Absence of this parameter indicates that the CLINK is to be used for a cluster connection.

PARTner=name

optionally, specifies the name of the VTSS at the receiving end of the CLINK that receives copies of the VTVs.

This parameter is required for CLINKs used for electronic export, or where the cluster consists of more than two VTSSs.

During validation of the link, this name is compared with the VTSS name at the other end of the CLINK.

CONFIg CLUSTER Statement

The CONFIg CLUSTER statement defines the VTSSs in a Cluster.

Syntax

Figure 3-16 shows CONFIg CLUSTER statement syntax.

Figure 3-16 CONFIg CLUSTER statement syntax

Surrounding text describes Figure 3-16 .

Parameters

As shown in Figure 3-16, the CONFIg CLUSTER statement includes the following parameters:

NAME=nnnnnnnn

specifies the 1 to 8 character identifier of the Cluster.

This parameter is required. There is no default value.

VTSSs(vtss-list)

Specifies the names of the VTSSs in a cluster. At least two VTSSs must be specified. If more than two VTSSs are specified, then down level hosts will not function.

The relationship between each of the VTSSs is defined by the CONFIG CLINK statement. See "CONFIg CLINK Statement" for more information.

This parameter is required. There is no default value.

VTSS names that you specify on a CLUSTER statement must be known to VTCS. That is, the VTSS names must be already defined in the CDS or must be specified in VTSS statements that already exist in the current set of CONFIg statements. For example, the following is valid:

VTSSNAME=VTSS1  LOW=70 HIGH=80  MAXMIG=3  RETAIN=5
VTSSNAME=VTSS2  LOW=70 HIGH=80  MAXMIG=3  RETAIN=5
CLUSTER NAME=CLUSTER1 VTSSs=(VTSS1,VTSS2)

The following is not valid unless VTSS1 and VTSS2 are already defined in the CDS:

CLUSTER NAME=CLUSTER1 VTSSs=(VTSS1,VTSS2)
VTSSNAME=VTSS1 LOW=70 HIGH=80 MAXMIG=3  RETAIN=5
VTSSNAME=VTSS2 LOW=70 HIGH=80 MAXMIG=3  RETAIN=5

The DEComp utility outputs CLUSTER statements with blanks instead of commas as separators, which is also valid input to CONFIg. For example, DEComp outputs the following, which is valid input to CONFIg:

CLUSTER NAME=CLUSTER1 VTSSs=(VTSS1 VTSS2)

CONFIg GLOBAL Statement

The CONFIg GLOBAL statement specifies VTCS global values. This statement is required.

Syntax

Figure 3-17 shows CONFIg GLOBAL statement syntax.

Figure 3-17 CONFIg GLOBAL statement syntax

Surrounding text describes Figure 3-17 .

Parameters

As shown in Figure 3-17, the CONFIg GLOBAL statement includes the following parameters:

MAXVTV=nnn

optionally, specifies the maximum number of VTVs that can be migrated to a single MVC. The default is 32000 for a D, E, or F level CDS and 65000 for a G level CDS. Valid values are:

4 to 32000 for a D, E or F level CDS
4 to 65000 for a G level CDS

For more information about CDS levels, see "CONFIg".

MVCFREE=nnn

optionally, specifies the minimum number of free MVCs in the MVC pool. A free MVC has 100% usable space and does not contain any migrated VTVs. Valid values are 0 to 255. The default is 40.

If free MVCs is equal or less than this value, VTCS issues message SLS6616I and starts an automatic space reclamation.

Note:

If you set MVCFREE=0, VTCS actually uses the default value (40).

VTVattr

optionally, specifies when VTCS assigns a Management Class to a VTV.

SCRATCH: Assign a Management Class only when VTCS does a scratch mount of the VTV (the default).
ALLmount: Assign a Management Class whenever VTCS mounts the VTV.

Caution:

If you specify that VTCS assigns a Management Class whenever VTCS mounts a VTV, these attributes can change, which can cause undesirable or unpredictable results.

For example, if an application writes data set PROD.DATA to VTV100 with a Management Class of PROD, then writes data set TEST.DATA to VTV100 with a Management Class of TEST, then the VTV (and both data sets) has a Management Class of TEST. Similarly, it is possible to write TAPEREQ statements or SMS routines that assign different Management Classes to the same data set (for example, based on job name), which can also cause a VTV's Management Class to change.

RECALWER

optionally, specifies whether VTCS recalls VTVs with read data checks (applies to recall and drain operations).

YES: Recall VTVs with read data checks (the default).
NO: Do not recall VTVs with read data checks.

LOCKSTR=structure-name

optionally, specifies the Coupling Facility Structure that holds VTCS Lock Data. structure-name must be 16 characters or less and conform to IBM's standard for naming Coupling Facility Structures. Refer to Oracle's ELS publication Installing ELS for more information.

Caution:

CONFIG RESET is required to add LOCKSTR=structure-name to a CDS that did not previously use LOCKSTR=structure-name and to remove LOCKSTR=structure-name from a CDS. CONFIG RESET is not required to change lock structure names (for example, going from LOCKSTR=VTCSL1 to LOCKSTR=VTCSL2).

REPlicat

optionally, specifies when VSM replicates the VTV.

ALWAYS

The replicate request is added to the VTCS replication queue every time the VTV is dismounted, regardless of whether the VTV was changed while it was mounted (the default).

CHANGED

The replicate request is added to the VTCS replication queue if either of the following have occurred:

The VTV was changed while it was mounted.
The VTV was only read while mounted but less than the expected number of MVC copies of the VTV exist.

Once the expected number of MVC copies exist, replication does not occur.

Regardless of the CONFIG GLOBAL REPlicat setting, replication also requires that:

The VTV must be dismounted in a VTSS that supports replication and there cannot be an identical copy of the VTV in the other VTSS in the Cluster.
In addition to the CONFIG GLOBAL REPlicat value, you must specify REPlicat(YES) on a VTV's Management Class for replication to occur.

VTVPAGE

optionally, specifies the page size used to store VTV data in the VTSS and on the MVCs. This setting only applies to 400 MB and 800 MB VTVs. If VTVPAGE is not specified on either the MGMTclas statement or the CONFIG GLOBAL statement, the default is STANDard.

STANDARD

standard page size, which is compatible with all VSM3 or VSM4 models and microcode levels.

LARGE

large page size, which can provide improved performance within the VTSS and for migrates and recalls. Large page size requires a G level CDS. For more information on CDS levels, see "CONFIg". For 2 GB VTVs and 4 GB VTVs (MAXVtvsz 2000 or 4000), a VTVPAGE setting of LARGE is always used.

VTVPAGE does not apply to VSM2s. VTVPAGE(LARGE) requires VSM4 or VSM5 microcode D02.02.00.00 or VSM3 microcode N01.00.77.00. No installed option is required.

MGMTCLAS VTVPAGE, if specified, overrides the CONFIG GLOBAL VTVPAGE value. If VTVPAGE is not specified on either the MGMTclas statement or the CONFIG GLOBAL statement, the default is STANDard.

Consider the following:

The page size of a VTV can only be changed by a VTV scratch mount. Additional restrictions may also apply for scratch VTVs that were previously resident in a VTSS.
If you specify LARGE and the CDS level or VTSS microcode does not support LARGE, then VTCS issues warning messages and VTVPAGE defaults to STANDard.
If you specify STANDard for 2 GB or 4 GB VTVs, then VTCS issues warning messages and defaults to LARGE.
Creating VTVs with large pages makes these VTVs unreadable in configurations that do not support large VTV pages.

NLIBDRNR

optionally, specifies how VTCS handles non-library resident MVCs for drain or reclaim processing.

YES: VTCS requests the mount of the non-library MVC. This is the default.
NO: VTCS suppresses the mount and purges the request.

For drain, non-library resident MVCs can be selected.

For reclaim, only library resident MVCs can be selected for processing, never non-library ones. However, between the time a library resident MVC is selected and the time it is actually processed, it may have become non-resident by being ejected.

NLIBMIGR

optionally, specifies whether non-library resident MVCs will be selected for Migration processing.

YES: Allow non-library resident MVCs to be selected (default).
NO: Do not allow non-library resident MVCs to be selected.

NLIBRECL

optionally, specifies whether non-library resident MVCs will be selected for Recall processing.

YES: Allow non-library resident MVCs to be selected (default).
NO: Do not allow non-library resident MVCs to be selected.

MVCMNTTO=nn

optionally, specifies the value in minutes when a mount of an MVC will timeout. Valid values are 5 to 30 minutes. The default is 15.

INITMVC

optionally, specifies whether un-initialized MVCs are to be initialized when they are first mounted.

NO: Un-initialized MVCs should not be initialized. This is the default.
YES: Un-initialized MVCs should be initialized.

SYNCHREP

optionally, specifies whether VTV synchronous replication feature is enabled.

NO: Synchronous replication is not enabled (the default).
YES: Synchronous replication is enabled.

Note:
SYNCHREP=YES merely enables synchronous replication. To actually implement synchronous replication, you must create a Management Class that specifies REPLicat=YES_SYNC For more information, see "MGMTclas Control Statement".

MAXRTDS

optionally, specifies the maximum number of RTDs supported.

16: up to 16 RTDs supported.
32: up to 32 RTDs supported.

FASTMIGR

optionally, specifies whether the stacked or streamed migrates feature is enabled for all VTSSs that support this feature.

STREAM

Specifies to use the streaming method for migrations. VTCS monitors responses from the RTD and uses them to decide as to when a VTV has become migrated. Full advantage is made of the buffer within the RTD to improve the throughput when performing migration.

This option also implies the use of the STACKED feature.

STACKED

Specifies to use the stacked method for migrations. VTCS maintains a small queue of requests to the VTSS. Advantage is made of the various buffers in the VTSS and RTD to improve the throughput when performing a migration. For backward compatibility, the value YES is the equivalent of STACKED.

NO

Disable stacked migrates (the default).

FASTMIGR=STREAM or STACKED has the following prerequisites:

FASTMIGR=STACKED: VSM4/VSM5 microcode D02.05.00.00 or higher. If this level of microcode is not installed on all VTSSs in the configuration, Stacked Migration will be limited to the VTSSs that have it installed.
FASTMIGR=STREAM: VSM4/VSM5 microcode D02.15.xx.00 or higher. If this level of microcode is not installed on all VTSSs in the configuration, Streamed Migration will be limited to the VTSSs that have it installed.
ELS 7.0 or higher with PTFs.
CDS level G or higher.
FICON ports for FICON RTDs and CLINKs.

For the Stacked Migration feature to be enabled, all hosts must be running the prerequisites, otherwise:

If a host is active and does not support or tolerate stacked migrates, then the CONFIg utility returns an error.
If a host is started and does not support or tolerate this feature, then the host shuts down.

LOGPOL

optionally, specifies whether VTCS CDS logging is optional or required.

OPTional

Logging is optional. This is the default. This mode is required for configurations that include 7.1 or 7.2 and lower level hosts.

REQuired

Logging is enabled for all events on all hosts that share the CDS. This requires all hosts to be at level 7.0 or higher. The following events are logged:

new version of VTV
imported VTV
first use or re-use of an MVC
imported MVC
add VTV to MVC
VTV on an imported MVC
unlink VTV from MVC
reclaim VTV from MVC
reset MVC EOT backwards
electronic export of VTV

MAXVTVSZ

optionally, specifies a default maximum compressed VTV size (MB) that may be used during the creation of VTVs. Valid values for this parameter depend on both the CDS level and the microcode levels of the applicable VTSSs.

400: 400 MB. This is the default.
800: 800 MB. The CDS must be at E level or above.
2000: 2 GB. The CDS must be at G level or above.
4000: 4 GB. The CDS must be at G level or above.

Considerations:

The size of a VTV changes only after it goes through a scratch cycle. Therefore, if you change the Management Class and DISP=MOD, then it will still retain the original size.
If you specify a VTV size that is not supported by the configuration, VTCS issues warning messages and MAXVtvsz defaults to the largest VTV size supported by the configuration.
MAXVtvsz does not apply to VSM2s.
MAXVTVSZ(2000) or MAXVTVSZ(4000) requires VSM4 or VSM5 microcode D02.02.00.00 or VSM3 microcode N01.00.77.00. No installed option is required.

The CONFIg GLOBAL and MGMTCLAS MAXVTVSZ parameters interact as follows:

If MAXVTVSZ is specified on MGMTCLAS, this value overrides the CONFIg GLOBAL MAXVTVSZ value.
If MAXVTVSZ is not specified on MGMTCLAS, the CONFIg GLOBAL MAXVTVSZ value, if specified, is used. Otherwise, MAXVTVSZ defaults to 400 MB.
If MAXVTVSZ is not specified on MGMTCLAS or on CONFIg GLOBAL, MAXVTVSZ defaults to 400 MB.

LOCKTOUT=nnn

optionally, specifies the minimum number of minutes that a resource is locked before message SLS6946E is issued.

Valid values are 0, or any value between 5 and 240. If 0 is specified, message SLS6946E will not be issued when a required resource is locked. If this parameter is not specified, the current default of 10 minutes is retained.

Note:

LOCKTOUT is only supported at &rsquor;F' level CDS (V61ABOVE) and above.

FASTRECL

Optionally specifies whether VTCS performs Early Time to First Byte (ETTFB), also known as concurrent tape recall/mount, for all VTSSs that support the feature. This parameter applies to recalls from RTDs and recalls from VLE.

NO: Disable the ETTFB feature. This is the default.
YES: Enable the ETTFB feature. If you globally enable this feature, you can disable it for individual VTSSs through the CONFIg VTSS NOERLYMT parameter. See "CONFIg VTSS Statement" for more information.

VTDGT256

Optionally, specifies whether greater than 256 VTDs are to be used.

Note:

VTDGT256=YES is only valid with VSM model 7 and above. VSM 7 VTSS supports 512 VTDs with current maintenance.

NO: Specifies that only the first 256 VTDs will be used. The first 256 VTDs are on control unit 00 - 0F of the VTSS with VDID address of x0000 - x0F0F. NO is the default.
YES: Specifies that all configured VTDs in the VTSS can be used. This is only valid if the VTSS supports greater than 256 devices. The feature is globally enabled and applies to all VSMs that support greater than 256 devices. The feature can be disabled for an individual VTSS through the CONFIG VTSS NOGT256 parameter. See "CONFIg VTSS Statement" for more information.

CONFIg HOST Statement

The CONFIg HOST statement is an optional statement that defines an MVS host and, optionally, the NOMIGRAT and/or NORECLAM parameters.

If specified, the HOST statement must follow the VTSS statement for the VTSS attached to that host.

You must either specify all host definitions or none; if you specify only some of the hosts attached to a VTSS, VTCS will issue an error.

Syntax

Figure 3-18 shows CONFIg HOST statement syntax.

Figure 3-18 CONFIg HOST statement syntax

Surrounding text describes Figure 3-18 .

Parameters

As shown in Figure 3-18, the CONFIg HOST statement includes the following parameters:

NAME=xxxx

specifies the LIBGENed hostname. xxxx indicates the host name.

NOMIGRAT

optionally, specifies that this host cannot do migrations, consolidations, or export by VTV or Management Class from the VTSS(s) that the host accesses. NOMIGRAT controls both automatic and demand migrations and consolidations. This parameter is optional.

Specifying NOMIGRAT also causes NORECLAM to be set.

IMMEDmig KEEP and IMMEDmig DELETE are mutually exclusive with CONFIG HOST NOMIGRAT. If you specify both, the IMMEDmig value overrides NOMIGRAT, and VTCS does not issue a message about this override.

NORECLAM

optionally, specifies that this host cannot initiate automatic or demand reclaim processing using the VTSS(s) that the host accesses. The host can still perform MVC drains using MVCDRain). This parameter is optional.

CMDCONN

optionally, specifies one of the following VTSS access methods:

CHANNEL: indicates ESCON or FICON channel access. This is the default.
TCPIP: indicates TCP/IP access. TCPIP requires a valid CONFIg VTSS IPCONN=(name-list) value.

CONFIg MVCVOL Statement

The CONFIg MVCVOL statement defines a range of MVCs available to VTCS.

Oracle recommends that you use SET VOLPARM to define VTV and MVC ranges in the VTCS CONFIg.

See "SET VOLPARM" for more information about the SET VOLPARM statement.
Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information about the use of the VTVVOL and MVCVOL statements in CONFIg to define volumes.

CONFIg RECLAIM Statement

The CONFIg RECLAIM statement controls demand and automatic MVC and VMVC space reclamation.

Syntax

Figure 3-19 shows CONFIg RECLAIM statement syntax.

Figure 3-19 CONFIg RECLAIM statement syntax

Surrounding text describes Figure 3-19 .

Parameters

As shown in Figure 3-19, the CONFIg RECLAIM statement includes the following parameters:

THRESHLD=nn

optionally, specifies the percentage of fragmented space (nn) that makes an MVC eligible for demand or automatic reclamation. Valid values are 4 to 98. The default is 75.

VLTHRES=nn

optionally, specifies the percentage of fragmented space (nn) that makes a Virtual MVC (VMVC) eligible for demand or automatic reclamation. Valid values are 4 to 98. The default is 35.

Note:

Reclaim on a VMVC consists of simply deleting the expired VTV images from the VMVC. That is, no recall and re-migrate of the VTV is required. VMVC reclaim is therefore much faster than MVC reclaim, and you can set VLTHRES lower (more aggressive) than THRESHLD.

MAXMVC=nn

optionally, specifies the maximum number of MVCs that will be processed by a single space reclamation task.

nn indicates the maximum number of MVCs. Valid values are 1 to 98. The default is 40.

For automatic space reclamation to start, the number of eligible MVCs (determined by the THRESHLD parameter) must also exceed the MAXMVC value.

START=nn

optionally, specifies the level at which automatic space reclamation starts for each ACS (not globally for all ACSs). Specify a percentage value, which is equal to:

Reclaim Candidates / (Reclaim Candidates + Free MVCs) * 100

where:

Reclaim Candidates indicates the number of Reclaim Candidates determined by the CONFIG RECLAIM THRESHLD parameter.
Reclaim Candidates + Free MVCs equals the number of Reclaim Candidates plus the number of free MVCs.Valid values are 1 to 98. The default is 35.

CONMVC=nn

optionally, specifies the maximum number of MVCs that VTCS concurrently processes for both drain and reclaim.

Valid values are 1 to 99. The default is 1.

INPLACE

optionally, enables or disables dynamic reclaim support within VTCS. There is no default, though the absence of INPLACE indicates that dynamic reclaim support is not enabled.

YES: Enable dynamic reclaim by formatting and processing all eligible MVCs as partitioned on a global (all storage class) basis.
NO: Disable dynamic reclaim. This option will likely be accompanied by STORCLAS level overrides.

The CDS must be at H level before INPLACE is accepted, enabling dynamic reclaim support. If INPLACE is specified and the CDS is not at H level, the configuration fails and error messages are displayed.

Only T10000B media is supported for dynamic reclaim. Sport volumes are not supported in partitioned format.

INPTHRSH=nn

optionally, specifies the percentage of fragmented space that makes an MVC in partitioned format eligible for dynamic reclaim processing.

nn is a percentage between 3 and 97. This value must be less than the THRESHLD value. The default is half the THRESHLD value (rounded up).

INPTHRSH cannot be specified without INPLACE.

If INPTHRSH is specified, THRESHLD must also be specified. Both INPTHRSH and THRESHLD play roles when dynamic reclaim processes MVCs in partitioned format. Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

PROTECT=nn

optionally, specifies the time, in hours, to prevent (or protect) an MVC from being reused after it is drained or reclaimed. Valid values are 1 to 99.

CONFIg RTDpath Statement

The VTCS CONFIg RTDpath statement defines the path to one of the following:

RTDs operating under a local TapePlex. Local RTD connections are defined using the DEVNO and CHANIF parameters and no STORMGNR parameter. Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.
A remote library. Remote library connections are defined via the DEVNO, CHANIF and STORMGNR parameters. Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.
A VLE connected to a VTSS, defined using only the STORMNGR and IPIF parameters. Refer to Oracle's ELS publication Configuring the Host Software for VLE for more information.

Except in tapeless environments, CONFIg RTDpath is required and must follow the VTSS statement that defines the VTSS to which the devices are connected.

The maximum number of each device type you can connect are as follows:

For a VSM2 or VSM3, 8 RTDs.
For a VSM4, 16 RTDs.
For a VSM5 or VSM6, 32 RTDs.
For a VSM5 or VSM6, 4 VLE appliances.

Note:

You must specify the RESET parameter to change RTD definitions if VTCS is running with a CDS level lower than V61ABOVE. See "CONFIg" for more information. For an initial RTD definition, if the RTD name displayed at the VTSS LOP is anything other than all blanks, you must also specify RESET.

Syntax

Figure 3-20 shows CONFIg RTDpath statement syntax.

Figure 3-20 CONFIg RTDpath statement syntax

Surrounding text describes Figure 3-20 .

Parameters

As shown in Figure 3-20, the CONFIg RTDpath statement includes the following parameters:

NAME=xxxxxxxx

specifies the 1 to 8 character identifier of the RTD or VLE appliance.

During VTCS CONFIg processing, RTDs with the same name may be defined for multiple VTSSs. RTD names must be unique across all VTSSs.
For RTDs, you set or change the RTD identifier only using the RTD NAME parameter. To do so, the RTD identifier must be all blanks as displayed at the VTSS LOP or DOP.
For VLEs or remote libraries, use any meaningful 1 to 8 character identifier.

This parameter is required; there is no default value.

STORMNGR=stormngr

specifies one of the following:

VLE subsystem name
remote library

stormngr indicates the Storage Manager name:

For VLEs, this value must match the VLE Subsystem Name.
For remote libraries, this value must match a TapePlex name defined on the SMC TAPEPLEX NAME parameter.

For more information, refer to Oracle's ELS publication Configuring the Host Software for VLE.

IPIF=ci:p

The IPIF value for each VTSS to VLE port connection in ci:p format where:

c indicates the VTSS Storage Cluster number (0 or 1).
i indicates the interface number (A or I)
p indicates the device number on the interface (0, 1, 2, or 3).

For a VSM5, this value must match the values specified on the VSM5 IFF Configuration Status Screen. For a VSM 6, this must be unique for each VTSS and does not correspond to an actual value on the VSM 6 TCP/IP ports.

DEVNO=nnnn

specifies the unit address of the RTD or remote library. This parameter is required with CHANIF. There is no default value.

CHANIF=ci or ci:p

specifies the channel interface on the VTSS that communicates with the RTD where:

c indicates the VTSS Storage Cluster number (0 or 1).
i indicates the interface number (A, C, E, G, I, K, M, or O)
p indicates the device number on the interface (0, 1, 2, or 3).

For a VSM5, this CHANIF value must match the actual FICON interface values. For a VSM 6, this must be unique for each VTSS and does not correspond to an actual value on the VSM 6 FICON ports. For remote library connections, this value must be unique for each library and must follow the ci:p rules for RTDs.

Regardless of whether the Maximum 32 RTDs feature is enabled, if you do not have greater than 16 RTDs attached to a VTSS, you can use the ”old” addressing scheme (CHANIF=ci).

If, however, the Maximum 32 RTDs feature is enabled and you have greater than 16 RTDs attached to a VTSS, you must use the ”new” addressing scheme (CHANIF=ci:p).

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

Caution:

For RTDs, driving mount and dismount commands to the device is version dependant. If the remote HSC server is running V6.2, then it is dependant upon the local SMC trapping the MVS message and forwarding the mount/dismount across to the HSC server as if it was a job. If the remote HSC server is running V7 or above, then this is automatically detected and VTCS directs a mount/dismount request directly to the remote HSC server. It is important that the SMC parameters only direct commands to servers of one of these types.

CONFIg STORMNGR Statement

The CONFIg STORMNGR statement defines a VLE to VTCS.

Note:

Do not specify this statement when down-level hosts are active. Once CONFIg STORMNGR is specified, down-level hosts no longer function.
This statement requires CDS level V62ABOVE or higher.
This statement is an alternative to the CONFIg TAPEPLEX statement. That is, you can either specify a list of VLEs on CONFIg TAPEPLEX or each VLE individually via CONFIg STORMNGR. If you code CONFIg STORMNGR statements, they must immediately follow the CONFIg TAPEPLEX statement to which the CONFIg STORMNGR statements apply.
For VTCS 7.2, you can define additional emulated VLE RTDs with the VLEDEV parameter. For more information, refer to Oracle's VLE publication Configuring the Host Software for VLE.

Syntax

Figure 3-21 shows CONFIg STORMNGR statement syntax.

Figure 3-21 CONFIg STORMNGR statement syntax

Surrounding text describes Figure 3-21 .

Parameters

As shown in Figure 3-21, the CONFIg STORMNGR statement includes the following parameters:

STORMNGR

specifies Subsystem Name of the VLE attached to the preceding TAPEPLEX statement.

NAME=name

the Subsystem name of the VLE, which is set by the VLE installation scripts.

VLEDEV(device-id-list)

optionally, specifies the logical device IDs of a VLE. This parameter requires CONFIG CDSLEVEL=V71ABOVE (CDS Level H) and applies to VLE 1.2.

device-id-list is a list or range of device IDs whose format is an 'S' prefix followed by three hexadecimal characters. These IDs are similar to MVS device addresses but do not overlap with the MVS name space. You can specify up to 96 device IDs per VLE, which defines each VLE with 96 emulated devices, which enables VTCS to schedule up to 96 processes on each VLE.

CONFIg TAPEPLEX Statement

The CONFIg TAPEPLEX statement defines values to VTCS for Cross-TapePlex Replication (CTR) or for replication to a VLE.

Do not specify this statement when down-level hosts are active. Once CONFIg TAPEPLEX is specified, down-level hosts no longer function.
This statement requires CDS level V61ABOVE or higher.
Refer to Oracle's ELS publications Managing HSC and VTCS and ELS Disaster Recovery and Offsite Data Management Guide for more information about Cross-TapePlex Replication.

Syntax

Figure 3-22 shows CONFIg TAPEPLEX statement syntax.

Figure 3-22 CONFIg TAPEPLEX statement syntax

Surrounding text describes Figure 3-22 .

Parameters

As shown in Figure 3-22, the CONFIg TAPEPLEX statement includes the following parameters:

THISPLEX=name

specifies the TapePlex name for this configuration. This name is associated with any VTV copies that are exported to other TapePlexes via Cross-TapePlex Replication.

name indicates the TapePlex name. This name must match the name specified on an SMC LIBrary or TAPEPlex command defined in the local SMC. The following rules apply:

The value must be between 1 and 8 characters in length.
The first character must be either an alpha character or digit.
The last character must be either an alpha character or digit.
Any character between the first and last must be either an alpha character, digit, or hyphen.

RECVPLEX(tapeplex-list)

optionally, specifies the list of TapePlexes from which VTV copies can be received (from Cross-TapePlex Replication). Attempts by hosts to send or scratch VTV copies from TapePlexes that are not included on the list are rejected.

tapeplex-list indicates the list of TapePlex names. The following rules apply:

The value must be between 1 and 8 characters in length.
The first character must be either an alpha character or digit.
The last character must be either an alpha character or digit.
Any character between the first and last must be either an alpha character, digit, or hyphen.

Note:

Specify RECVPLEX on the receiving TapePlex. You can also specify RECVPLEX on the sending TapePlex to allow this TapePlex to recall a VTV from the receiving TapePlex.

STORMNGR(stormngr-list)

optionally, specifies Subsystem Names of the VLEs attached to this TapePlex.

stormngr-list indicates the list of VLE subsystem names. For more information, refer to Oracle's ELS publication Configuring the Host Software for VLE.

CONFIg VTD Statement

The CONFIg VTD statement defines the MVS unit address range of the VTDs in a VTSS. This statement is required and must follow the VTSS statement where the VTDs reside.

Note:

VSM2s and VSM3s provide 64 VTDs per VTSS. VSM4s and later models provide 256 VTDs per VTSS.

You can specify the VTD unit addresses to either apply to all hosts or to define which VTDs are available to specific hosts. See "Specifying VTD Unit Addresses" for more information.

Syntax

Figure 3-23 shows CONFIg VTD statement syntax.

Figure 3-23 CONFIg VTD statement syntax

Surrounding text describes Figure 3-23 .

Parameters

As shown in Figure 3-23, the CONFIg VTD statement includes the following parameters:

LOW=xxxx

specifies a four character valid MVS unit address (xxxx) as the start of a range of VTDs.

HIGH=xxxx

specifies a four character valid MVS unit address (xxxx) as the end of a range of VTDs.

CUADDR=xx

optionally, specifies a control unit identifier (xx) that matches its value in the IOCP. Valid values are 0 through 15 for VSM4 and 0 through 3 for VSM2 or VSM3. This statement is required only if a partial VTD range is specified for a host and the host does not have a path to the VTDs.

NOVERIFY

optionally, suppresses VTD verification.

Normally, VTCS attempts verification of all predicted VTD identifiers associated with Virtual Tape Drives. In order to do this, each MVS I/O address must be available to allow the associated Host to issue the ECAM-T request Virtual_Device_Identify. ECAM is the method VTCS uses to communicate with a VTSS when bringing a VTSS online and scheduling replication and migrations.

In specific cases where, for example, VTCS is providing support for a remote client host, the local host, acting as a server for the remote client, may not have paths to the MVS I/O address. In these cases, any attempt at verification of the predicted VTD identifier fails and results in error messages posted to the operator. NOVERIFY suppresses verification and prevents these failures.

When NOVERIFY is specified for a device or range of devices, the following occurs:

The device is reported to SMC so that VTVs can be mounted from MVS.
VTCS does not use that device for ECAM I/O. At least one device must be left without NOVERIFY so that it can be used for ECAM I/O.

Specifying VTD Unit Addresses

To specify VTD addresses, do one of the following:

Specify the VTD unit addresses on a VTD statement following a VTSS statement and do not specify any HOST statements following the VTSS statement. All hosts physically connected to the VTSS have access to its VTDs by the default addresses specified on the VTD statement.
Do not specify the VTD unit addresses on the VTD statement following a VTSS statement. Instead, place a VTD statement after a HOST statement for only those hosts for which you want to define connections to the previously defined VTSS. You must specify a placeholder (HOST NAME with no VTD parameter) for any hosts that you do not want connected to this VTSS.

The VTVs created and MVCs initially written to from a VTSS are considered to be resources of that VTSS. Therefore, only hosts with access to a VTSS have access to its VTVs and MVCs. In this type of ”restricted” access configuration, each host should have a separate VTV scratch pool to ensure that each host has accurate scratch counts. Similarly, free MVCs and MVC reclaim counts are reported on each host for the MVCs associated with the VTSS to which the host is connected.

You can specify different address ranges for each host, although Oracle recommends that you specify the same address ranges for all hosts for consistency of operations. If you specify different address ranges for different hosts, use the HSC SET DRVHOST and SMC DRIVEMAP statements if you have a client/server configuration. You must include UNITATTR MODEL(IGNORE) commands for all overgenned devices (including VTDs) on all MVS hosts.

Caution:

In a multi-host, multi-VTSS configuration, you can use this VTD addressing method to deny access to VTSSs to which hosts are physically connected. You must, however, use this method to deny access from hosts that are not physically connected to a VTSS. If you do not deny access, VTCS on a host that does not have physical connections to a VTSS may wait, trying to communicate with the VTSS while VSM operations may be stalled on all other hosts.

CONFIg VTSS Statement

The CONFIg VTSS statement defines a VTSS and sets its operating values. This statement is required.

When you define a new VTSS, place its definition after any existing VTSS definitions, which must remain in their original order.

Syntax

Figure 3-127 shows CONFIg VTSS statement syntax.

Figure 3-24 CONFIg VTSS statement syntax

Surrounding text describes Figure 3-24 .

Parameters

As shown in Figure 3-24, the CONFIg VTSS statement includes the following parameters:

Note:

If you physically remove a VTSS from your configuration, reconfigure the VTSS with a VTSS statement only (no parameters).

NAME=xxxxxxxx

specifies the VTSS name (xxxxxxxx). This parameter is required; there is no default value. The VTSS name can consist of the characters "A-Z", "0-9", "@", "$", and "#".

You specify the VTSS name only via the NAME parameter, which sets the VTSS name in both the VTSS microcode (as displayed in the Subsystem Name field in the LOP or VOP) and in the configuration area of the HSC CDS. After VSM is put into operation, the VTSS name is also stored in each VTV record in the CDS. Each VTV record contains the VTSS name on which that VTV is resident. If the VTV is migrated, the VTV record contains the VTSS name from which the VTV was migrated.

Once you set the VTSS name via the NAME parameter, you cannot change this identifier in the HSC CDS. That is, the CONFIg utility does not allow you to change the NAME parameter after an initial setting and changing the VTSS name using the Subsystem Name field of the LOP or VOP cannot change the VTSS name in the HSC CDS.

Caution:

Do not attempt to rename a VTSS that contains data on VTVs, which includes VTSS-resident VTVs and migrated VTVs.

For an initial setting only (not a change), you can set the VTSS name in the NAME parameter only if the VTSS name value in the VTSS microcode is one of the following:

The factory setting (all blanks).
A value of 99999999 (eight 9s).

Therefore, for an initial setting only, if the name in the VTSS microcode is not all blanks or 99999999, your Oracle StorageTek hardware representative must use the VTSS LOP or VOP to set the VTSS name to 99999999. This enables you to set the VTSS name to the value you want via the NAME parameter.

DEFLTACS=acs-id

optionally, VTCS supports multi-VTSS confirmations, and supports connecting multiple ACSs to each VTSS. In configurations where a VTSS is connected to multiple ACSs, use the DEFLTACS parameter to specify the default ACS (acs-id) from which MVCs will be selected for migration, consolidation, and reclaim processing. You can migrate up to 4 VTV copies to separate ACSs (per MGMTclas statement) from the MGMTclas MIGpol parameter (and ignores the DEFLTACS parameter, as described below).

If you do not specify DEFLTACS, the default value is x'FF', which enables VTCS to select MVCs from any ACS.

VTCS ignores the DEFLTACS value if you specify the DEFLTACS parameter and do either of the following:

Specify the ACSlist parameter of the MGMTclas statement.
Use a Storage Class.

LOW=nn

optionally, specifies the low automatic migration threshold (LAMT) for this VTSS. nn indicates the threshold value.

Valid values are 5 to 95 and must be less than the HIGH default threshold. The default is 70.

HIGH=nn

optionally, specifies the high automatic migration threshold (HAMT) for this VTSS. nn indicates the threshold value.

Valid values are 6 to 95 and must be greater than the LOW default threshold. The default is 80.

MAXMIG=n

optionally, specifies the maximum number of concurrent automatic migration, immediate migration, and migrate-to-threshold tasks for this VTSS.

n indicates the number of tasks. Valid values are 1 to the number of RTDs attached to the VTSS. The default is half the number of RTDs attached to the VTSS.

MINMIG=n

optionally, specifies the minimum number of concurrent automatic migration, immediate migration, and migrate-to-threshold tasks for this VTSS.

n indicates the number of tasks. Valid values are 1 to the MAXMIG setting. The default is 1 task.

RETAIN=nn

optionally, specifies the number of minutes that VTCS retains an MVC on an RTD in idle mode after a migration or recall. Retaining the MVC can reduce MVC mounts.

nn indicates the number of minutes. Valid values are 1 to 60. The default is 15.

An MVC on an idle RTD is not dismounted until the RETAIN time has elapsed, unless the RTD in question is required, and no other 'like RTDs' (same ACS, LSM, and device type) are free.

An exception to this behavior occurs when the last operation on the RTD was a job-initiated recall or an 'MVC is full' condition has occurred. In this case, the MVC is dismounted from the idle MVC when VTCS has determined that, although the RTD is not currently needed, there are no other 'like' RTDs free.

NOERLYMT

optionally, disables Early Time to First Byte (ETTFB), also known as the concurrent tape recall/mount feature, for this VTSS. This parameter only applies if CONFIg GLOBAL FASTRECL=YES. This parameter applies to recalls from RTDs and recalls from VLE.

CMDCONN

optionally, specifies the VTSS access method:

CHANNEL: indicates ESCON or FICON channel access. This is the default.
TCPIP: indicates TCP/IP access. This requires a valid CONFIg VTSS IPCONN=(name-list) value.

IPCONN=(name-list)

optionally, specifies a comma-separated list of one to four IP addresses, either explicitly as IP addresses or implicitly by names that resolve to IP addresses, used to define TCP/IP connections.

name-list indicates the list of IP addresses or names. Values entered in the list cannot be verified until a VTCS system is initialized to use them. They must meet the following requirements:

Any IPv4 values must be specified in format nnn.nnn.nnn.nnn, where each byte is one to four hexadecimal characters. There must be four bytes, numeric only except for the decimal points.
Any IPv6 values must be specified in format x.x.x.x.x.x.x.x, where each byte is 0-255. There must be four bytes: 0-9, A-F (or a-f). IPv6 abbreviations are not allowed. The full eight part address must be specified.
If names are specified, they can be a maximum of 60 characters. A name can be any valid DNSname containing only the characters A-Z, a-z, 0-9, '-', or '.'.

NOGT256

optionally, disables greater than 256 VTD support for this VTSS. This parameter only applies if CONFIG GLOBAL VTDGT256=YES is specified.

Note:

VTDGT256=YES is only valid with VSM model 7 and above. VSM 7 VTSS supports 512 VTDs with current maintenance.

CONFIg VTVVOL Statement

The CONFIg VTVVOL statement defines a range of VTVs.

Oracle recommends using SET VOLPARM to define VTV and MVC ranges in the VTCS CONFIg.

See "SET VOLPARM" for more information about the SET VOLPARM statement.
Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information about the use of the VTVVOL and MVCVOL statements in CONFIg to define volumes.

Active HSC/VTCS

Description

The DELETSCR command deletes scratch VTVs from VTSSs and unlinks any migrated VTVs from MVCs.

Syntax

Figure 3-28 shows DELETSCR command syntax.

Figure 3-28 DELETSCR command syntax

Surrounding text describes Figure 3-28 .

Parameters

As shown in Figure 3-28, the DELETSCR command includes the following parameters:

VTVid(volser, vol-range, or vol-list)

optionally, specifies one or more VTVs to be deleted.

volser, vol-range, or vol-list indicates the volsers of one or more VTVs.

MGMTclas(mgmtclas-name)

optionally, specifies the Management Class(es) of the VTVs.

mgmt-class-name indicates the Management Class name that you specified on the MGMTclas control statement.

SCRPool(scrpool)

optionally, specifies the scratch pool(s) to be deleted. If the pool contains VTVs and real volumes, DELETSCR deletes only VTVs.

scrpool is an existing HSC scratch pool.

VTSS(vtss-name)

optionally, causes scratch VTVs within the specified VTSS to be deleted.

vtss-name indicates the VTSS name.

Note:

VTVid, MGMTclas, SCRPool, and VTSS are mutually exclusive. If you do not specify one of these parameters, VTCS processes all scratch VTVs.

NOTREF(days)

specifies the number of days since a VTV was last referenced for it to be deleted by DELETSCR.

days indicates the number of days (1-999).

MAXVTV(nnn)

optionally, specifies the maximum number of VTVs that DELETSCR deletes. Note that this is a maximum, not a target.

nnn indicates the maximum number of VTVs (0-999). If not specified, DELETSCR deletes all scratch VTVs. If you specify 0, DELETSCR does not delete any VTVs, but the summary report shows how many VTVs would have been deleted...at the point at which you ran DELETSCR (that is, the report is just a snapshot).

DETail

optionally, produce a detailed report that also shows detail and summary of VTVs that fall within the NOTREF period.

DIRBLD

Interfaces:

Utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The DIRBLD command rebuilds the database directory for all defined CDS copies.

The control data set contains a directory of pointers to various important locations and if damaged, can cause operational problems. Normally, HSC corrects such errors automatically. The DIRBLD utility repairs a corrupted CDS database directory. This utility can be run while the HSC is stopped or running to repair damage to the directory and maintain continuous operation. It must be run using all CDS copies as input.

Caution:

Contact Oracle StorageTek Support before running the DIRBLD utility to insure that the CDS is not further damaged by inappropriate use or inappropriate operational conditions.

Syntax

Figure 3-29 shows DIRBLD command syntax.

Figure 3-29 DIRBLD command syntax

Surrounding text describes Figure 3-29 .

Parameters

None.

DISMount

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The DISMount command dismounts a cartridge or VTV.

Although the volume may be rewound and unloaded by the operating system, it may not be dismounted from the real drive or VTD. This command is provided for instances where hosts are not communicating with a specific ACS (disconnected mode).

Hosts that are still communicating (connected mode) may be able to semi-automate tape handling for hosts that cannot communicate with a specific ACS. When HSC or VTCS does not dismount a volume, you must ensure that the volume is unloaded before you issue the DISMount command.

Note:

The HSC DISMount command does not support VTDs that are not defined in the VTCS CONFIG. The SMC DISMOunt command must be used in place of the HSC DISMount command for any VTDs that are not specified in the VTCS CONFIG.

Syntax

Figure 3-30 shows DISMount command syntax.

Figure 3-30 DISMount command syntax

Surrounding text describes Figure 3-30 .

Parameters

As shown in Figure 3-30, the DISMount command includes the following parameters:

volser

optionally, specifies which volume to dismount. The volser operand is optional. If it is not specified, the robot dismounts whatever volume is mounted on the device.

If volser is not specified, a comma must be entered immediately before the device address to indicate the missing operand. For example:

DISMOUNT ,B00

devaddr

specifies the device address of the transport from which the volume is to be dismounted.

host-id

optionally, indicates that the DISMount command is to be performed for the device address of the specified host (the SMF system identifier for both JES2 and JES3).

FORCE

optionally, specifies that the drive will be unloaded before the volume is dismounted. This parameter is not valid for virtual drives.

Note:

*ABORT appears in the display of reclaim requests if the request has cancelled or abended.

Fields

The Function column shows the hierarchy of requests by indenting. The VTSS column shows either a VTSS name or a VTSS list. The Task column shows which task is currently servicing the request (same information as reported in Display Tasks).

Depending upon the parameters supplied, the output may contain only requests for a specific VTSS, be just the requests in a queued state, be just requests in an active state or be all requests. As can be seen above, the VTV and MVC columns are also used to expose additional information about the nature and status of the request.

         09 C1I  SECNDARY On-Sync   Free                 DVTSS17  #009

Fields

Display CLink command output includes the following fields:

VTSS

the Primary or Sending VTSS name.

CLINK

a composite of the device Id that has been assigned to the CLINK within the VTSS and the back end channel interface to which it is connected.

NAME

one of the following values:

name: the name of the TapePlex to which the CLINK is connected. This also indicates that the CLINK will be used for electronic exporting of VTVs. The VTSS name in the Partner column indicates the VTSS that will receive VTV copies over this CLINK.
-Cluster: indicates that the CLINK is used for replication of VTVs within the TapePlex and is part of a cluster. The VTSS name in the Partner column indicates the other VTSS that operates in the cluster.

STATUS

one of the following link statuses:

Maint: The link has failed or it has been varied into maintenance mode.
Offline: The link is offline and unavailable to all hosts and VTSSs.
Online: The link is available for replication.
P_offlne: The link is pending offline.
P_online: The link is pending online.
On-Sync: Available for synchronous replication.
On-Async: Available for asynchronous replication.
Recovery: The link is being reset following an error or a vary online operation.
Unusable: Not available for replication due to hardware errors or assigned-elsewhere conditions.
UUI err: This is a CLINK defined for electronic export and it has been unable to contact the remote VTCS. There should be messages in the HSC JOBLOG that indicate the reason for the problem. This could include problems with the definitions, the local SMC, or the remote HTTP server on the remote VTCS.

USAGE

one of the following link usages:

Assigned: Link is assigned to the host in the HOST field but is not currently replicating. This usage occurs when VTCS is starting or terminating link use or is attempting error recovery on the link after a replication failure.
Free: Link is idle (not doing replications).
Replicating: Link is actively doing replications.

HOST

the host that the link is assigned to.

PARTNER

the secondary or receiving VTSS.

VTD

the address of the VTD on the partner VTSS that forms the other end point to the connection. For a cluster link, the MVS address of the VTD is reported. For an electronic export link, this is not possible as there is no access to the other TapePlex configuration. In this case, only the ordinal number of the VTV is reported.

Display CLUster

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The Display CLUster command displays Cluster status.

Syntax

Figure 3-37 shows Display CLUster command syntax.

Figure 3-37 Display CLUster command syntax

Surrounding text describes Figure 3-37 .

Parameters

None.

Output

The following is an example of the output produced by the Display CLUster command:

Example 3-14 Display CLUster output

NAME       VTSS       STATE      DIRECTION  VTSS       STATE      MODE
CLUSTER1   HBVTSS16   ONLINE     ------>    HBVTSS17   ONLINE     Sync-replicate
CLUSTER2   HBVTSS18   ONLINE     <------    HBVTSS19   QUIESCED   DEGRADED
CLUSTER3   HBVTSS20   ONLINE     <------    HBVTSS21   ONLINE     Async-replicate
CLUSTER4   HBVTSS22   QUIESCED   <----->    HBVTSS23   ONLINE     DEGRADED

Fields

Display CLUster command output includes the following fields:

NAME

the Cluster name.

VTSS

one of the VTSS in a Cluster.

DIRECTION

One of the following:

----> or <----: Indicates the direction of VTV replication in Uni-Directional Cluster. VTVs can only be replicated from the Sending to the Receiving VTSS.
<---->: Indicates that the VTSSs are configured as a Bi-Directional (Peer-to-Peer) Cluster. VTVs can be replicated from either VTSS to the other.

STATE

one of the following VTSS states:

QUIESCING: Quiescing state.
QUIESCED: Quiesced state.
OFFLINE: Offline state.
OFFLINE-P: Offline pending state.
ONLINE: Online state.
ONLINE-P: Online pending state.
STARTED: The VTSS is initialized and in process of going to the requested state (online, offline, or quiesced).

MODE

one of the following Cluster operating modes:

Async-replicate

Both VTSSs in the Cluster are online to VTCS. Production workload can go to either VTSS, but in the case of a Uni-Directional (Primary/Secondary) Cluster, VTVs can only be replicated from the Sending VTSS. Synchronous replication is not enabled across the cluster.

Sync-replicate

Degraded

One of the two VTSSs in a Bi-Directional (Peer-to-Peer) Cluster is either offline or quiesced. Production workload can go the remaining online VTSS. VTVs requiring replication, however, are allocated to the remaining VTSS only if no other Full-Function clusters are available and suitable. In this case, replicate VTVs are migrated immediately with keep and queued for replication when the other VTSS comes online.

When the other VTSS comes online, VTCS reconciles the contents of both VTSSs.

Table 3-2 Display EXceptns Error Messages

Message	Description
`CAP Not Operational`	The CAP is not operational.
`CAP Door is Open`	The CAP door is open.
`CAP Door is Unlocked`	The CAP door is unlocked.
`CAP is Reserved`	The CAP is reserved.
`Pass Thru Port is Inoperative`	The pass thru port is inoperative.
`Robot Hand is Inoperative`	The robot hand is inoperative.
`Robot Hand needs maintenance`	The robot hand is in need of maintenance.
`LSM is Not Ready`	The LSM is in a not ready state.
`LSM is Offline`	The LSM is in an offline state.
`LSM is Offline Pending`	The LSM is in an online pending state.

`LSM Door is Open`	The LSM door is open.
`LMU Compat 10 or less; not all functions supported`	The LMU will not be able to respond correctly to some of the status queries until its microcode is updated. This condition will also cause SLS0662I LMU Response Error to be issued just before SLS4610I.
`Station` `nn` `has Inactive Connection:`	A hardware connection to the LMU is not usable. This may be normal for your configuration if the connection has never been made and is not necessary. The station number is in hex, so Station 0A is the tenth station, and Station 10 is really the sixteenth.
`Station` `nn` `Inoperative; Host not responding:`	The station number is in hex, so Station 0A is the tenth station, and Station 10 is really the sixteenth.

The following messages are summaries:

No CAP problems were detected
No Pass Thru Port problems were detected
No Robot Hand problems were detected
No LSM problems were detected

Fields

Display MVC command output includes the following fields:

VOLSER

the volser of the MVC.

MEDIA

the volume media type or recording technique. Should the value &rsquor;Need PTF' appear, then this host lacks support for this media type. Another host does have support for this media type.

ACSID

the ACS containing the MVC, or the VLE containing remote MVC volumes or VMVCs in VLEs. This will not appear if the MVC has been ejected from the library.**MANY** indicates that an MVC with a specific volser has been discovered in more than one location. MVCs in this state are marked unusable.

SIZE (MB)

the size of the MVC in megabytes.

MIGRATED COUNT

the number of VTVs migrated.

VTV COUNT

the number of active VTVs on the MVC.

%USED

the percentage of the MVC used by valid VTVs.

%FRAGMENTED

the percentage of the MVC that has invalid VTV space that is not available for use until it is reclaimed or the MVC is drained.

%AVAILABLE

the percentage of the MVC that is physically available for use.

%USABLE

the percentage of space on the MVC that can be used by VTCS. This may be zero even if there is still space physically available. For instance, if the VTV per MVC limit is reached then the %Usable will be reported as 0%. Similarly, if an error has been reported against an MVC then VTCS will not use this MVC for output and the %Usable will be reported as %0.

TIMES MOUNTED

the number of times the MVC has been mounted for writing or reading since it was added to the MVC inventory

LAST MOUNTED

the date and time at which the MVC was mounted or attempted to be mounted upon a RTD.

LAST MIGRATED

the date and time at which the last VTV migration was performed to the MVC.

LAST VERIFIED

the date and time at which the last VTV media verify was performed to the MVC.

This date reflects the last time that VTCS knew the MVC contents were valid where the date is the most recent of the following:

The date/time the MVC was verified with MEDVERfy.
The date/time the MVC was migrated to from an empty state.

LAST DRAIN/RECLAIM

the date and time at which the MVC was last processed by Drain or reclaim processing and had it's end-of-tape pointer reset.

OWNER

the Storage Class that owns the MVC. An MVC only becomes a member of a storage class when it contains migrated VTVs.

VTSS

the last VTSS that performed a migration to the MVC. CONSOLIDATE appears in this field for consolidated VTVs.

MVCPOOL

either an MVC Pool Name (including DEFAULTPOOL) or NO if the MVC is not defined on an MVCPool statement.

SECURITY ACCESS

VTCS permissions for the MVCs defined in an MVCPOOL statement (UPDATE, NO UPDATE, or NO PROFILE).

STATUS

one of the following statuses:

INITIALIZED

The MVC has been initialized.

BEING AUDITED

The MVC is either currently being audited or has been the subject of a failed audit. While in this state the MVC will not be used for migration and can be used for recalls. Due to the inherent state, recalls may fail because the CDS not yet up-to-date with the MVC contents. To clear this condition, rerun the AUDIT utility against this MVC.

LOGICALLY EJECTED

The MVC has either been the subject of an MVCDRain Eject or the MVC was rejected for update by a RACROUTE call. The MVC will not be used again for migration. To clear this condition, use MVCDRain against the MVC without the Eject option.

NOT-INITIALIZED

The MVC has been defined via the CONFIg utility, but has not ever been the subject of a successful VTV migration.

MOUNTED

The MVC is mounted on an RTD.

IN ERROR

This is a generic error that indicates the MVC, drive, or combination of the two has specifically reported a problem whilst accessing the MVC. VTCS attempts to de-preference the usage of MVCs with this state. VTCS considers this to be the most serious affliction on a MVC when considering copies to be used for recalls.

In general, to clear this state:

If the MVC caused the problem, use a DRAIN(EJECT) command to remove the MVC from service.
If the RTD caused the problem, use the MVCMAINT utility to reset the MVC state.

Note:

One or more of the following messages is issued for IN ERROR status: SLS6686, SLS6687, SLS6688, SLS6690. Refer to Oracle's ELS publication ELS Messages and Codes for recovery procedures for these messages.

MARKED FULL

The MVC is considered as being full and is not a candidate for further migrations. Due to the general behavior of tape media this can occur before the MVC has reached its nominal capacity.

DRAINING

The MVC is either currently the subject of drain or reclaim processing. Should the processing fail, the MVC maybe left in this state as a safeguard. To clear this condition, perform an MVCDRain against the MVC.

LOST - FAILED TO MOUNT

VTCS attempted to mount an MVC and the mount did not complete within a 15-minute time-out period. VTCS has had no specific error report although there could be combination of hardware problems, HSC problems, or by the MVC being removed from the ACS. VTCS attempts to de-preference the usage of MVCs with this state.

Determine the cause of the error and fix it. You can also use the VTCS MVCMAINT utility to set LOST(OFF) for the following events:

LOST(ON) was set due to LSM failures or drive errors that have been resolved
LOST(ON) was set because the MVC was outside the ACS and has been reentered.

This condition is automatically cleared by VTCS if it subsequently requests a mount of the MVC and this is successful.

DATA CHECK

A data check condition has been reported against this MVC. VTCS attempts to de-preference the usage of MVCs with this state. To get into this state, a data transfer must have failed upon two different RTDs.

To clear this state:

If all VTVs on the MVC are duplexed, use MVCDRain on the MVC without the Eject option. This recovers all VTVs and removes the MVC from service.
If all VTVs on the MVC are not duplexed, VTCS AUDIT the MVC. The audit will probably fail. After the audit, do an MVCDRAIN (no eject). This recalls the VTVs before the data-check area in ascending block-id order and the VTVs after the data-check area in a descending block-id order. Processing the VTVs in this sequence ensures that VTCS recovers as many VTVs as possible from the media. You then need to recreate the data for any VTVs still on the MVC.

Note that although this indicates that a specific failure has occurred when performing data transfers, this may not be a fault in the media. It could be that a RTD is writing data to the media out of specification. Patterns of failures are therefore important. As an example, lots of DATA CHECK conditions suddenly occurring lots of drives and volumes.

READ ONLY

The MVC has been marked read-only because of one of the following conditions:

The MVC being the target of an export or consolidation process. The read-only state protects the MVC from further updates.
The MVC media is set to file protect. Correct the error and use the MVCMAINT utility to set READONLY(OFF).
The MVC does not have the appropriate SAF rules set to enable VTCS to update the MVC. Correct the error and use the MVCMAINT utility to set READONLY(OFF). Refer to Oracle's ELS publication Installing ELS for information about defining a security subsystem user ID for HSC, SMC, and VTCS.

RETIRED

The MVC is retired and is considered by VTCS as having reached the end of its useful life. VTCS will recall from, but not migrate to, the MVC. Replace the MVC as soon as possible. Once this has been done, use the MVCMAINT utility to set RETIRED(OFF).

WARRANTY HAS EXPIRED

The MVC's warranty has expired. VTCS continues to use the MVC. You should start making plans to replace the MVC when it reaches Retired state.

INVALID MIR

VTCS has received status from an RTD to indicate the MIR (media information record) for a 9x40 media is invalid. An invalid MIR does not prevent access to data but may cause significant performance problems while accessing records on the tape. The MVC is not capable of high-speed searches on areas of the tape that do not have a valid MIR entry.

VTCS attempts to de-preference MVCs with this condition. For recalls, if the VTV resides on multiple MVCs, VTCS selects MVCs with valid MIRs ahead of MVCs with invalid MIRs. VTCS avoids using MVCs with invalid MIRs for migration, unless the migration is at the beginning of the tape. Migrating from the beginning of tape will correct the MIR. VTCS detects the invalid MIR condition at either mount time or dismount time. If detected at mount time and the operation can be completed with another MVC, VTCS dismounts the first MVC and selects the alternate MVC.

VTCS has only a limited ability to switch to an alternate MVC. That is, it is mainly used for migrate and virtual mount. For MVCs with invalid MIRs, determine the cause of the error, which may be caused by media or drive problems, and fix the error. To recover an MVC with an invalid MIR, read the MVC to the end of the tape, via a VTCS audit. If the media is the problem, run an MVCDRAIN EJECT to recall the VTVs and cause the MVC to be removed from the MVC pool.

MIGRATES NOT SUPPORTED

This host lacks support for performing migrations to this MVC. This is set by another host that does support migration.

RECALLS NOT SUPPORTED

This host lacks support for performing recalls from this MVC. This is set by another host that does support recalls.

RECLAIM NOT SUPPORTED

This host lacks support for considering this MVC for reclaim processing. This is set by another host that does support reclaim processing. This does not inhibit the MVC being processed through the MVCDRain command.

DEDUP requested on last mount

DEDUP(YES) was requested on the last mount.

FORMAT

the VTV format, standard or partitioned.

RTD – A direct connection to a RTD
VLIB – A data path connection to a Virtual Library
CLINK - A CLINK used for cluster replications within the tapeplex
EEXP – A CLINK used for electronic export to another tapeplex

RTDNAME

The name allocated to the path. For paths defined via the RTDPATH statement in the configuration, this is the name assigned through the RTDNAME parameter. For a CLINK or EEXP type path, this column will contain the target VTSS name.

CHANIF

the logical device ID assigned to the path and the CHANIF or IPIF value that was specified for the path.

Target

the destination subsystem for the path. For a VLIB type path, this contains the STORMNGR name assigned to the Virtual Library. For a CLINK type path, this contains the name of the cluster. For the EEXP type paths, this contains the tapeplex name to which the path is connected.

Device

the destination device for the path. For an RTD type path, this contains the MVS address of the tape device. If this is a VLIB path that is working in compatibility mode, this will contain the logical device address assigned to the path.

State

The current state of this path. This can be one of the following:

Online: the path is online and available for use.
On-Async: the path is online and available for use for asynchronous replication of VTVs.
On-Sync: the path is online and available for use for synchronous replication of VTVs.
Offline: the path or the device to which it connects has been varied offline.
Maint: the path or the device to which it connects has been varied into an offline maintenance mode. This could be as a result of repeated failures.

Display SCRAtch

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The Display SCRatch command displays scratch counts by subpool name, ACS id, LSM id, media type, recording technique, or owning host name.

Syntax

Figure 3-60 shows Display SCRAtch command syntax.

Figure 3-60 Display SCRatch command syntax

Surrounding text describes Figure 3-60 .

Parameters

As shown in Figure 3-60, the Display SCRATch command includes the following parameters:

acs-id: optionally, the ACS for which the system is to display scratch count information. If you specify acs-id without an LSM number, selected scratch counts for the entire ACS are displayed.
lsm-id: optionally, the LSM for which the system is to display scratch count information.
VSM: optionally, restricts the Display SCRatch display to subpools with virtual volumes. VSM is not allowed if acs-id or lsm-id are also specified.

Note:

If acs-id or lsm-id is specified, it must be the first parameter after the SCRatch keyword. The VSM keyword is not positional.

SUBpool(subpool-name)

optionally, restricts the scratch count display to the named subpool only. If SUBpool is specified, then LSM and ACS totals will reflect only the named subpool. SUBpool is not allowed if HOSTid is also specified.

subpool- name indicates the name of the subpool. Specify up to 13 characters.

HOSTid(name)

optionally, restricts the scratch count display to subpools that are accessible from the named HOSTid. If HOSTid is specified, then LSM and ACS totals will reflect only subpools that can be accessed from the named HOSTid. HOSTid is not allowed if SUBpool is also specified.

name indicates the SMFID or the SMC SERVER ALIASHOST ID of the host. Specify up to 8 characters.

MEDia(media-type)

optionally, restricts the scratch count display to the volumes compatible with the specified media name. If MEDia is specified, then LSM and ACS totals will reflect only the compatible media types.

media-type indicates the media type.

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

RECtech(recording-technique)

optionally, restricts the scratch count display to volumes compatible with the specified recording technique. If RECtech is specified, then LSM and ACS totals will reflect only the compatible recording techniques.

recording-technique indicates the recording technique.

See Appendix A, "MEDia, RECtech, and MODel Values" for valid recording-technique values.

DETail

optionally, lists scratch counts by all media and recording techniques. If specified, then an additional level of media and recording technique detail is displayed for every subpool. DETail is not allowed if either MEDia or RECtech are also specified.

REFresh

optionally, updates VSM scratch counts prior to the display occurring.

Note:

The REFresh parameter causes additional I/Os to the CDS and must be used sparingly.

ALL

optionally, lists scratch counts for subpools that have both a 0 scratch count and 0 threshold value. Normally, the Display SCRatch command will only list subpools that have either a non-zero scratch count or non-zero threshold value. Specification of ALL overrides this filter and results in the display of all defined scratch pools.

Output

The following are examples of the output produced by the Display SCRatch command.

The following example shows counts for all LSMs in all ACSs:

the Storage Class name, which can be any Storage Class, not just those defined via the MGMTDEF command. Thus, stor-clas-name can take the value of a vtss-name or !ERROR, in order to allow details of migrations to these Storage Classes to be displayed.

DETail

optionally, the output lists VTVs currently queued for automatic migration or immediate migration with this Storage Class.

MAXvtv(nnnn)

optionally, indicates the maximum number of VTVs to be listed in a single automatic migration or immediate migration list (for a VTSS).

nnnn indicates a maximum number of VTVs, from 0-9999. If not specified, a default value of 100 is used.

MAXvtv(nnnn) implies DETail.

Caution:

When you specify MAXvtv(nnnn), high values can cause temporary system degradation due to the number of WTO (write to operator) messages issued.

STATUS

one or more of the following statuses:

CONSOLIDATED: VSM has consolidated the VTV.
DUPLEXED: The DUPLEX attribute has been assigned to this VTV. When VSM migrates the VTV, a copy will be written to two MVCs.
EXPORT-NOT POSSIBLE: Export of this VTV to a remote TapePlex was attempted and the request was rejected. Typically, this is due to a different copy of the VTV residing in the remote TapePlex.
EXPORT-REJECTED: Electronic export to one or more TapePlexes was actively rejected. This could be due to the target TapePlex not allowing import of the VTV, or a clash with copy status.
EXPORT-REQUIRED: This VTV should be electronically exported and is currently queued for processing.
EXPORT-STARTED: Electronic export is active for this VTV, but not yet complete.
INITIALIZED: VTCS has used the VTV at least once.
MIGRATED: VSM has migrated the VTV.
MIGRATE PENDING: VTV migration is pending. This status is displayed when a VTV is initially created, or when the VTV requires reconciling or archiving. In these latter cases, individual MVC copies may indicate Reconcil or Deletion.
REPLICATION COMPLETE: A fully replicated copy of this VTV is now resident in the Secondary VTSS.
REPLICATION REQUIRED: This VTV should be replicated and is currently queued for processing.
REPLICATION STARTED: Replication is active for this VTV but not yet complete.

concurrent recall/mount encountered an error with this VTV. No further concurrent recall/mount activity will be attempted for this VTV.

DRAin

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The DRAin command terminates an eject or enter operation on one or more CAPs, which frees the CAP resources for use by other processes.

Syntax

Figure 3-75 shows DRAin command syntax.

Figure 3-75 DRAin command syntax

Surrounding text describes Figure 3-75 .

Parameters

As shown in Figure 3-75, the DRAin command includes the following parameters:

cap-id or cap-list

one or more CAPs to be drained. The CAPids specified on a DRAin command must match the CAPids specified on the associated EJect or ENter command.

The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

Each caplist element can be either an lsmid or a capid that describes a specific CAP. The elements in a list must be separated by a comma or a blank, and the entire list must be enclosed in parentheses.

ENter

specifies that an enter operation is to be terminated on the specified CAPs. ENter is the default.

EJect

specifies that an eject operation is to be terminated on the specified CAPs.

DRCHKPT

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC/VTCS at FULL service level

Description

The DRCHKPT command establishes the system recovery point (checkpoint) from which MVC content can be recovered from for a period of time.

Syntax

Figure 3-76 shows DRCHKPT command syntax.

Figure 3-76 DRCHKPT command syntax

Surrounding text describes Figure 3-76 .

Parameters

As shown in Figure 3-76, the DRCHKPT command includes the following parameters:

SET: Sets a date/time stamp in the active CDS which establishes the recovery point. Beginning at this recovery point, MVC content is guaranteed for a period of time in the future (for example, until another DRCHKPT utility is run).
CLEAR: Removes any recovery point set in the active CDS. Once removed, MVC content cannot be guaranteed.

DRMONitr

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC/VTCS at FULL service level

Description

The DRMONitr utility stalls job stream processing to ensure that critical data reaches its target destination. Once all identified data is accounted for, the utility ends.

DRMONitr can monitor for MVC and remote TapePlex copies being complete. It can also monitor for cluster replication being complete, in support of tapeless environments.

DRMONitr reports any VTV exception conditions found during execution.

Syntax

Figure 3-77 shows DRMONitr command syntax.

Figure 3-77 DRMONitr command syntax

Surrounding text describes Figure 3-77 .

Parameters

As shown in Figure 3-77, the DRMONitr command includes the following parameters:

MGMTclas(name)

optionally, specifies a list of Management Classes to be monitored for VTV migrate/copy completion.

name indicates one or more Management Classes.

Specified Management Classes must be defined to the active VTCS system and must specify immediate migrate. For tapeless environments, specified Management Classes must specify REPLICAT.

VTVid(volser)

optionally, specifies a list and/or range of VTV volsers to be monitored for migrate/copy completion.

volser indicates one or more volume serial numbers.

The VTV's Management Class must be defined to the active VTCS system and must specify immediate migrate, i.e. the Management Class must specify IMMEDmig(KEEP), IMMEDmig(DELETE) or IMMDELAY(n).

For tapeless environments, the VTV's Management Class must specify REPLICAT.

DSN(name)

optionally, specifies a list of data sets to be monitored for migrate/copy completion.

The VTVs containing these data sets must have Management Classes defined to the active VTCS system and must specify immediate migrate. For tapeless environments, the VTV's Management Class must specify REPLICAT.

STORclas(name)

optionally, specifies the Storage Class locations that the identified VTV data is to be delivered to.

name indicates one ore more Storage Class locations.

Specified Storage Classes must be defined to the active VTCS system. Although this parameter is optional, the STORclas parameter should only be omitted in tapeless environments.

REPLICAT

optionally, specifies that VTV cluster replication is to be monitored for completion. Replication must be specified on the VTV's Management Class policy for the VTV to be selected for monitoring. If replications are monitored in a tape environment, their completion overrides any Storage Class requirement.

MAXAGE(nnn)

optionally, specifies the maximum VTV age (time since last update), in hours, when monitoring migrations by Management Class (a MGMTclas value is required).

nnn indicates the age in hours.Valid values are 1 to 999. There is no default.

If the VTV's age (time since last update) is greater than MAXAGE, the VTV is not monitored. DRMONitr reports the number of skipped VTVs due to MAXAGE, if specified.

If you do not specify MAXAGE, any active VTV belonging to the specified Management Classes, regardless of age, is monitored for migrate or copy completion.

TIMEOUT(nnn)

optionally, specifies the maximum time, in minutes, for DRMONitr to run.

nnn indicates the maximum time. Valid values are zero to 999. If you do not specify a TIMEOUT value, there is no limit on the time the utility can run (stall).

A TIMEOUT value of zero does not stall the DRMONitr utility. This special case reports on incomplete copies of specified VTV data.

If a non-zero TIMEOUT value is exceeded, DRMONitr ends with RC 8 and generates an error message. If the TIMEOUT value specified was zero, a return code of 4 is set if a VTV's copy is detected as incomplete, otherwise a return code 0 is set.

Note:

You must specify either STORclas or REPLICAT or both to specify the destination criteria. Otherwise DRMONitr ends with RC 8 and generates an error message. Additionally, Oracle recommends that you do not specify (or monitor) Storage Classes in tapeless environments because migrations are not possible.

DRTEST

The DRTEST command sets up the environment for DR testing and optionally, starts and stops the test.

Issue this command from the SLUADMIN utility to set up the DR testing environment. Once the environment is set, you can issue DRTEST from a utility or the console to start or stop testing.

Issue this command with any of the options listed in the following table. Each option is described individually, and in more detail, on the pages to follow.

Table 3-5 DRTEST Options

Option	Description
`CREATE`	creates a DR test CDS, normally run at the DR test site
`PRIMEprd`	updates the production CDS without creating a `DRTEST CDS`
`RESET`	removes all DR test settings in the production CDS
`START`	starts the DR test on the production site. `DRTEST START` cannot run successfully until the production CDS is primed using `DRTEST PRIMEprd` or `DRTEST CREATE`.
`STOP`	stops the DR test on the production site

Note:

You can use a combination of these options provided you have correct environment and JCL requirements. For example, DRTEST STOP and DRTEST RESET can be run in the same job, however, DRTEST STOP must be run before DRTEST RESET.
Refer to Oracle's ELS publication ELS Disaster Recovery and Offsite Data Management Guide for information about how to use the DRTEST utility.

DRTEST CREATE

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The DRTEST CREATE command creates a DR test CDS, normally run at the DR test site.

Note:

The NOUPDprd parameter is only valid if the DRTEST PRIMEprd command is executed prior to the DRTEST CREATE command. See "DRTEST PRIMEprd" for more information.

Consider the following:

DR test cannot be active. This refers to the production CDS status.
Active HSC/VTCS is not required.
- If HSC/VTCS is active, SLSCNTL DD statement(s) identifying the production CDS are optional, and if included, must match the active HSC/VTCS.
- If HSC/VTCS is not active, SLSCNTL DD statement(s) identifying the production CDS are required.
SLSNEW DD statement(s) identifying the DRTEST CDS(s) are required.

Sample Control Cards:

DRTEST CREATE HOSTID(ZIPF,ZIPG) -
 DRVTSS(VTSSW) -
 DRACS(00)

Syntax

Figure 3-78 shows DRTEST CREATE command syntax.

Figure 3-78 DRTEST CREATE command syntax

Surrounding text describes Figure 3-78 .

Parameters

As shown in Figure 3-78, the DRTEST CREATE command includes the following parameters:

HOSTID(hostid1,hostid2,...hostidn)

Specifies the host IDs replicated in the test CDS in available host-id positions. The combination of existing production HOSTIDs and those identified in this parameter for replication cannot exceed the 16 host limit. If an additional host-id (not used in production) needs to be added for DR test purposes alone, this additional host-id will use 2 of the 16 host-ids in the limit.

DRVTSS(vtss1,vtss2,...vtssn)

Optionally, specifies the VTSS names available to the DR test site. Unless you also specify the SHARE or SPARE parameter, these VTSSs are offline to the production site and online to the DR test site when the DR test starts.

SPARE: Optionally, specifies that the DR test VTSS(s) are spares and that identically named VTSS(s) exist and are online at the production site when the DRTEST utility is run and during the DR test.
SHARE: Optionally, specifies that the DR test VTSS(s) are shared with the production site. During the DR test, both the test and production site may create VTVs in the DR test VTSS (based on the VOLPARM definitions). The DR test cannot modify VTVs that are not in a DR test subpool. The parameters DRACS and STORMNGR cannot be specified if SHARE is specified.

STORMNGR(stormngr-list)

Optionally, specifies the subsystem names of the VLEs attached to the DR test site TapePlex.

stormngr-list indicates the list of subsystem names. For more information, refer to Oracle's ELS publication Configuring the Host Software for VLE.

DRACS(acsid1, acsid2,...acsid16)

Optionally, specifies one or more ACSs available to the DR test site. Multiple ACS IDs must be specified as a list, and not as a range of ACS IDs. The ACSs are online to the DR test site but can remain connected (and usually are) to the production site when the DR test starts.

If the DRVTSS SHARE parameter is specified, the DRACS parameter is not allowed.
If the STORMNGR parameter is specified, the DRACS parameter is allowed but not required.

NOUPDprd

Optionally, does not update the input production CDS(s).

If this parameter is specified, you can use a single CDS production copy as input and that copy can be either the actual primary production CDS, a backup copy, or a mirrored copy.

This parameter is only valid if the PRIMEprd function has already been run on the production CDS. See "DRTEST PRIMEprd" for more information.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the DRTEST CREATE JCL:

SLSNEW1

specifies the new primary copy of the test HSC CDS.

SLSNEW2

specifies the new secondary copy of the test HSC CDS.

SLSNEW3

specifies the new standby copy of the test HSC CDS.

SLSJRN00 – SLSJRNnn

DDNAMEs for the DR test journal files, which are only valid if the current CDS defines journaling. There are two files per HOSTID: SLSJRN00 and SLSJRN01 for hostid1, SLSJRN02 and SLSJRN03 for hostid2, etc.

SLSSTATN

DDNAME for LMU station address changes for HOSTIDs. This file is optional, and if not supplied the same station addresses are used in the DR test CDS for the HOSTIDs as in the existing CDS.

Each entry follows the HSC SET SLISTATN utility format. See "SET SLISTATN" for more information. The following figure shows an example of the SLSSTATN file:

Example 3-46 SLSSTATN File

SET SLISTATN(00E7,00E8),FORACS(01),FORHOST(PRIT)
SET SLISTATN(00E7,00E8),FORACS(01),FORHOST(PRI1)
SET SLISTATN(00E7,00E8),FORACS(01),FORHOST(PRI2)
SET SLISTATN(00E7,00E8),FORACS(01),FORHOST(PRIY)

SLSVTSS

DDNAME for VSM changes on the DR test CDS. This file is optional and is only used if the DR test configuration includes VSM elements. Typically, this file is used to change RTD hardware connection definitions in the DR test CDS but may be used to modify any VSM definitions on the DR test CDS because the file invokes the VTCS CONFIg RESET utility.

Caution:

Improper use of CONFIg RESET against the DR test CDS may render the DR test environment inoperable!

Each entry follows the format of the VTSS, VTD, RTD, and HOST statements of the VTCS CONFIg utility. See "CONFIg" for more information. The following figure shows an example of the SLSVTSS file:

Example 3-47 SLSVTSS File

specifies whether MVC copies on the target TapePlex are to be deleted as part of the export process.

volser indicates a volser from the MVC copy to be deleted from the target VTVs. If not specified, then all MVC copies of the VTV are deleted.

This parameter only applies when the VTV version sent matches the version in the target TapePlex. If the versions sent is more recent, then the behavior is implicit.

This parameter can be used if the only MVC copies of a VTV in the target TapePlex become damaged. A replacement copy of the VTV can be supplied to the TapePlex via the EEXPORT command. The damaged MVC copies are replaced by additional migrations from the VTV copy sent.

FORCE

specifies whether VTCS exports the VTV to locations with disregard for other criteria.

YES: Export VTVs to the TapePlex specified in the TOPlex parameter, regardless of whether the VTVs have been previously exported to the TapePlex, or the management class points to a storage class that specifies the target TapePlex.
NO: Export VTVs to the TapePlex specified in the TOPlex parameter, but ignore any VTVs already marked as exported, and exclude any VTVs for which the management class does not point to a storage class that specifies the TapePlex in the TOPlex parameter. This is the default.

REJECTED

specifies whether VTCS only selects VTVs recorded in the CDS as being rejected by the target TapePlex. REJECTED and FORCE are mutually exclusive.

NO: Ignore any VTVs already marked as exported, and exclude any VTVs for which the management class does not point to a storage class that specifies the TapePlex in the TOPlex parameter. This is the default.
YES: Only select VTVs previously rejected by the target TapePlex.

RECALWER

specifies whether VTCS recalls VTVs with read data checks.

NO: Do not recall VTVs with read data checks. This is the default.
YES: Recall VTVs with read data checks.

NOWAIT

specifies that the utility does not wait for the operation to complete and returns after the request is submitted.

EJect

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The EJect command moves volumes to a Cartridge Access Port (CAP) for removal.

You can designate a single CAP or a list of specific CAPs. Specifying one or more CAPs limits cartridge ejection to those CAPs.

Ejections in a multiple ACS configuration may specify CAPs in each ACS if volumes reside in each ACS. If a list of CAPs is not provided, HSC selects the highest priority CAP available for each ACS (see "CAPPref").

You may elect to submit multiple EJect requests, each of which may specify a particular CAP. If you elect to specify a CAP in a multi-ACS configuration, then the list of volumes must reside within the CAP ACS.

Multiple CAPs within one ACS can be allocated to the EJECt utility. Specifying multiple CAPs in a single EJect utility typically improves performance by reducing pass-thrus.

If two CAPs are specified in the same LSM, cartridges in that LSM are ejected in sequential order. This is helpful for vaulting.

Syntax

Figure 3-84 shows EJect command syntax.

Figure 3-84 EJect command syntax

Surrounding text describes Figure 3-84 .

Parameters

As shown in Figure 3-84, the EJect command includes the following parameters:

TEXT(text)

optionally, specifies the address of a 44-byte string issued whenever the operator is requested to open the CAP for an EJect request. This text is displayed via message SLS1251E.

text indicates the text string.

PMSG(nn)

optionally, specifies a user defined message to be displayed in the SLConsole CAP status screen for a CAP when the door is unlocked for cartridge removal.

nn is a two character numeric value from 00 to 99. Specify one of the following values:

00 - No message is displayed.
01 - Display Remove cartridges message.
02 - Display Lib not available message.
03 - Display Load cartridges message.
04-99 - Display customized user messages.

Option 1 Parameters

As shown in Figure 3-84, the EJect command includes the following parameters:

volser, vol-range, or vol-list

one or more VOLSERs to be ejected. This can be a single VOLSER, a range of VOLSERs or a list of VOLSERs and/or VOLSER ranges in any combination.

If a list is specified, the elements must be delimited by commas or blanks, and the entire list enclosed in parentheses. A range of VOLSERs consists of a starting VOLSER and an ending VOLSER separated by a dash.

acs-id, lsm-id, cap-id, or cap-list

the ACS, LSM, or CAP for the cartridges to be ejected.

acs-id identifies the ACS containing the cartridges to eject. The HSC selects a non-zero preference CAP to use in the specified ACS.

lsm-id identifies the LSM containing the cartridges to eject. If the LSM has more than one CAP, an available CAP with the highest nonzero preference is selected.

cap-id identifies a specific CAP to use regardless of the assigned preference value. cap-id is of the form AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP number. The CAP numbers are dependent on the LSM type.

cap-list requires explicitly specified CAPids separated by commas. A CAPid range is not allowed. CAPids must be separated by blanks or commas, and the entire list must be enclosed in parentheses. If no CAP is specified, one is chosen in each ACS.

Note:

If neither acs-id, lsm-id, cap-id, or cap-list is specified, HSC selects a non-zero preference CAP in each ACS that contains volumes to be ejected.

SEQ

optionally, specifies whether or not CAP eject processing fills the CAP cells in the same order specified by the volser, volser-range, or vol-list.

If SEQ is not specified, but two CAPs are requested in the same LSM, and the LSM is not an SL8500, cartridges in the ACS are ejected in sequential order.

For best performance, SEQ(NO) is recommended.

NO: specifies to eject the requested volumes in the order of home cell location. EJect processing fills the CAP or magazine (for the SL8500) according to the distance of the home cell to the CAP or magazine; that is, volumes closest to the CAP or magazine are ejected first.
YES: specifies to eject cartridges to the CAP in the order the volumes are listed in the associated vol-list. The first cartridge requested appears in the topmost CAP cell, the second cartridge requested appears in the next CAP cell, etc. until the CAP is full or all cartridges have been moved to the CAP.

WAITcap

optionally, specifies whether or not a list of ejecting volumes waits for an available CAP if one is not available.

YES: specifies that the eject process waits indefinitely for a CAP to become available. YES is the default.
NO: specifies that the eject process does not wait for a CAP if it is not available.

Option 2 Parameters

As shown in Figure 3-84, the Display EJect command includes the following parameters:

SCRTCH

indicates that scratch volumes are to be ejected.

Note:

If neither acs-id, lsm-id, cap-id, or cap-list is specified, HSC selects a non-zero preference CAP in each ACS that contains volumes to be ejected. HSC selects a non-zero preference CAP in ACS 00.

acs-id, lsm-id, cap-id, or cap-list

the ACS, LSM, or CAP for the cartridges to be eject.

acs-id identifies the ACS containing the cartridges to eject. The HSC selects a non-zero preference CAP to use in the specified ACS.

lsm-id identifies the LSM containing the cartridges to eject. If the LSM has more than one CAP, an available CAP with the highest nonzero preference is selected.

SUBpool(subpool-name)

optionally, specifies the subpool from which scratch volumes are to be ejected. If MEDia or RECtech are specified, cartridges are ejected for that media type or recording technique within the same subpool.

subpool-name indicates the name for the subpool.

VOLCNT(count)

optionally, specifies that a designated number of scratch volumes are to be ejected.

count indicates the number of scratch volumes to be ejected.

MEDia(media-type)

optionally, specifies that scratch cartridges of the desired media are to be ejected.

media-type indicates the media type. See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

Note the following:

If MEDia is not specified, the next scratch cartridge is selected without regard to media type if RECtech does not exist. If both MEDia and RECtech are supplied, they must be compatible.

If SUBpool is not specified, then the next scratch cartridge is selected without regard to whether it belongs to a subpool, is defined to the default subpool using VOLPARMS, or belongs to no scratch subpool whatsoever.

RECtech(recording-technique)

optionally, specifies scratch cartridges of the desired recording technique are to be ejected. RECtech indicates the method used to record data tracks on the tape surface.

recording-technique indicates the recording technique. See Appendix A, "MEDia, RECtech, and MODel Values" for valid recording-technique values.

Note:

If RECtech is not specified, the next scratch cartridge is selected depending on the media type (if supplied). If neither is supplied, the next scratch cartridge is selected without taking media type and recording technique into consideration. If both RECtech and MEDia are supplied, they must be compatible.

WAITcap

optionally, specifies whether or not a list of ejecting volumes waits for an available CAP if one is not available.

YES: specifies that the eject process waits indefinitely for a CAP to become available. YES is the default.
NO: specifies that the eject process does not wait for a CAP if it is not available.

STORclas(stor-clas-name or stor-clas-list)

specifies one or more Storage Classes that determine one or more MVCs for export.

When an Export by STORclas is performed, the CDS maintains the MVC information in the VTV record of the CDS. The MVC will is marked as (R)ead-Only.

stor-clas-name or stor-clas-list indicate the names of one or more Storage Classes that you defined on the STORclas control statement. See "STORclas Control Statement" for more information.

Note:

EXPORT STORclas can create a manifest for VTVs that have been migrated to vMVCs in a VLE.

MANIFEST(ddname)

optionally, specifies the output destination dd-name of the manifest file. The default is MANIFEST.

RECALWER

optionally, specifies whether VTCS recalls VTVs with read data checks.

Yes: Recall VTVs with read data checks (the default).
No: Do not recall VTVs with read data checks.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the EXPORT JCL:

manifest file DD: DD statement for the manifest file (optional).

FMTLOG

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The FMTLOG command is part of the HSC/VTCS transaction logging service.

This command pre-formats a log file to be used by the logging service. It pre-formats data blocks and writes certain control information in the first record of the file. You can format a maximum of two log files with a single FMTLOG utility command.

Note:

You must pre-format a log file before activating it with the SET LOGFILE utility command. See "SET LOGFILE" for more information. You must execute the OFFload LOGfile before executing SET LOGFILE to specify a different log file data set name. See "OFFload" for more information.

Syntax

Figure 3-88 shows FMTLOG command syntax.

Figure 3-88 FMTLOG command syntax

Surrounding text describes Figure 3-88 .

Parameters

None.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the FORMAT LOGFILE JCL:

SLSLOG1: specifies the log file to be formatted.
SLSLOG2: specifies the second log file to be formatted.

IMPORT

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS not required

Description

The IMPORT command imports VTVs and MVCs listed on a manifest file into a VSM system.

Note:

Ensure that the ”to” CDS has the same features (enabled by CDS level) as the ”from” CDS. For example, if the ”from” CDS has large VTV page sizes enabled and 2/4 Gb VTVs have been created, then the ”to CDS” must have the same capabilities, otherwise the import fails.

Syntax

Figure 3-89 shows IMPORT command syntax.

Figure 3-89 IMPORT command syntax

Surrounding text describes Figure 3-89 .

Parameters

As shown in Figure 3-89, the IMPORT command includes the following parameters:

VTV(volser, vol-range, or vol-list)

specifies one or more VTVs to import.

volser, vol-range, or vol-list indicate the volsers of one or more VTVs.

MVC(volser, vol-range, or vol-list)

specifies one or more MVCs to import.

volser, vol-range, or vol-list indicate the volsers of one or more MVCs.

REPLACE

specifies whether VTCS replaces the VTV record in the target CDS. There is no default. You must specify a value.

NONE: Do not replace the VTV record. VTCS only creates new records for VTVs that are not duplicates and replaces records for VTVs not initialized in the target CDS.
UPDATED: Replace the VTV record if it is a more recent version of the VTV, or if the CDS has no migrated or resident versions of the VTV. If it is an older or the same version, do not replace the VTV record.
ALL: Replace any duplicate VTV records in the target CDS.

Considerations:

Ensure that you actually want to replace duplicate VTV records in the target CDS before you specify the ALL parameter. You may want to do a ”validate” run with NOUPDATE to see which VTV records will be replaced.
If a VTV record is replaced, all existing VTSS and MVC copies of the VTV are invalidated.
You cannot import an MVC if the target CDS records show that the MVC contains VTVs, even if you specify REPLACE(ALL). In this situation, you must first drain (with EJect) the MVC on the target system and eject it from the ACS. You can then import the MVC that you exported from the source system.

MANIFEST(dd-name)

optionally, specifies the input dd name of the manifest file.

dd-name indicates the dd name of the manifest file. The default is MANIFEST.

NOUPDATE

optionally, specifies that VSM does not update the CDS, validates the import operation, and writes information messages to the job log.

IMMDRAIN

optionally, specifies whether VSM will immediately drain imported MVCs.

NO: Do not drain MVCs (the default).
YES: Drain MVCs.

INACTCDS

optionally, specifies that the import uses a different CDS from the CDS currently active on the HSC system where you are running the import job. Use the SLSCNTL definition statement in the SLUADMIN JCL to specify the alternate CDS.

If HSC is down on the system where you are running the import job, the CDS on that system is assumed to be inactive, so you do not need to specify INACTCDS.

If you specify the INACTCDS parameter, the CDS specified in the SLSCNTL definition statement in the SLUADMIN JCL must be different from the CDS being used by HSC/VTCS (if active).

OWNRPLEX(name)

specifies ownership of a VTV being imported.

name indicates the name of the TapePlex that owns the original copy of the VTV. This name must match one of the known TapePlex names in the configuration.

If this name matches that indicated for the THISPLEX parameter on the CONFIg TAPEPlex statement, the electronic imported status is removed.

SETOWNER

specifies that ownership information is to be imported.

By default, any ownership information within the manifest is ignored. The SERTOWNER parameter specifies that the TapePlex ownership and export fields are imported. VTVs appear as if electronically imported on Display commands and reports.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the IMPORT JCL:

manifest file DD: DD statement for the manifest file.

INITialize

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

HSC at FULL service level

Description

The INITialize command enables you to batch enter cartridges into the library through the CAP, and invokes a user-specified program to write a magnetic label on each tape.

The robot accepts cartridges placed into the CAP and reads the Tri-Optic labels, and the HSC passes the VOLSERs to the user-specified program. The magnetically labeled cartridges can be ejected from the library or placed into cell locations. If the cartridges are stored in the library, the control data set is updated with the VOLSER and location information. The control data set can mark each cartridge as either scratch or nonscratch.

INITialize reads the external Tri-Optic labels and records them in a data set defined through the CNTLDD parameter. CNTLDD is a control statement parameter that describes the DDname to be used for TMSTPNIT control statements.

The INITialize utility does not initialize cartridges on its own; it invokes TMS, TLMS, or any other initialization utility, which performs the initialization. CNTLDD specifies, through the HSC to the TMS utility, the DD to be used for the input parameters the TMS utility requires.

Caution:

This utility must be executed on an MVS system running SMC and using a local HSC server.

Syntax

Figure 3-90 shows INITialize command syntax.

Figure 3-90 INITialize command syntax

Surrounding text describes Figure 3-90 .

Parameters

As shown in Figure 3-68, the INITialize command includes the following parameters:

CAP(cap-id)

optionally, specifies a particular CAP to be used for the operation.

If CAP is not specified, the utility chooses a CAP in the ACS implied by the device allocated to satisfy the SLSTAPE DD statement.

capid indicates the CAP. The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

PROGram(prog-name or IEHINITT)

optionally, specifies a program to be invoked to actually write the label (if not specified, IEHINITT is assumed).

prog-name indicates the program that is to perform the initialization.

VERIFY(parameter-name)

optionally, specifies a parameter to be passed to the tape initialization program identified by the PROGram parameter. VERIFY is valid only when the PROGram parameter specifies TMSTPNIT.

parametername indicates the parameter passed to the TMSTPNIT program. For example, if the following parameter is entered:

VERIFY(ROBOT)

TMSTPNIT suppresses the TMS CAL0TN01 message for NL (nonlabeled) tapes. Refer to the appropriate CA1 publication for valid parameter values.

CNTLDD(dd-name or SYSIN)

optionally, specifies the DD statement to which initialization control statements are written, and from which the label program reads its control statements.

Note:

This is not your control data set.

dd-name indicates the name of the DD statement. The ddname option may only be specified when using CA1 (TMS) prior to version 5.1. The default value (SYSIN) MUST be used with CA1 (TMS) version 5.1 or later.

OPTION

optionally, specifies optional handling to be performed following the completion of label processing. If not specified, the default is retention of the new cartridges in the library with a nonscratch status.

EJEct: specifies that the labeled volumes are to be ejected from the library after the labeling process is complete.
SCRatch: specifies that the labeled volumes entering the library are to be added to the scratch list. If the volume is to be treated as scratch, the installation must inform the tape management system of the volume's scratch status.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the INITialize JCL:

SLSINIT

substitution control card format for the invoked initialization program.

SLSTAPE

library transport on which the cartridge is mounted for labeling. To prevent a nonlibrary transport from being allocated, specify one of the following:

an esoteric containing only library transports
a specific library transport address
a TAPEREQ statement to direct the allocation to a library transport
a user exit (refer to Oracle's ELS publication ELS Legacy Interfaces Reference)

CNTLDD or SYSIN

contains volume serial labeling information and is passed as input to the initialization program (IEHINITT or the program specified by the PROG keyword parameter).

If CNTLDD is specified in the utility control statement, then the DD name identifies the data set containing the labeling information.

SYSPRINT

output messages from IEHINITT.

contains volume serial labeling information and is passed as input to the initialization program (IEHINITT or the program specified by the PROG keyword parameter).

If CNTLDD is specified in the utility control statement, then the DD name identifies the data set containing the labeling information.

INVENTRY

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The INVENTRY command lists all VTVs on specified MVCs.

Additionally, you can use this command to do the following:

Request that the contents of the specified MVCs are cross-checked with the information recorded in the CDS.
Terminate processing based on the end-of-tape position recorded in the CDS for the MVC, rather than at the MVC's physical end-of-tape.
Terminate processing for an MVC the first time a VTV is discovered that is incompatible with the information in the CDS.

Syntax

Figure 3-91 shows INVENTRY command syntax.

Figure 3-91 INVENTRY command syntax

Surrounding text describes Figure 3-91 .

Parameters

As shown in Figure 3-91, the INVENTRY command includes the following parameters:

MVCid(volser, vol-range, or vol-list)

specifies the MVC(s) to be inventoried.

volser, vol-range, or vol-list indicates the volsers of one or more MVCs. You can also specify one or more ranges.

CDScheck

optionally, specifies whether the contents of each inventoried MVC is checked against the information recorded in the CDS.

None

Each VTV found on an inventoried MVC is listed via message SLS6933I. The CDS is not checked. None indicates the default.

Mvc

Each VTV found on an inventoried MVC is listed via message SLS6933I. The details of the VTV are obtained from the CDS. The MVC and CDS copies of the VTV are compared and listed as a comment on SLS6933I. If the CDS shows a resident or MVC copy of the VTV that differs from the copy listed in SLS6933I, its details are listed via message SLS6934I.

Full

Each VTV found on an inventoried MVC is listed via message SLS6933I.

The details of the VTV are obtained from the CDS. The MVC and CDS copies of the VTV are compared and listed as a comment on SLS6933I. If the CDS shows a resident or MVC copy of the VTV that differs from the copy listed in SLS6933I, its details are listed via message SLS6934I. For each inventoried MVC, the CDS is checked to determine which CTCs are shown to have a copy on the MVC. Any MVCs that were not found on the MVC are listed in message SLS6935E.

STOPleot

optionally, specifies whether processing is to terminate when the logical end-of-tape position is reached. The logical end-of-tape position is the end-of-tape position recorded in the CDS for this MVC.

NO

All VTVs are to be processed on each inventoried MVC. This is the default.

YES

VTVs are processed on each inventoried MVC until one of the following occurs:

The MVC's physical end-of-tape is reached.
The first VTV is found on the MVC that is beyond the logical end-of-tape position, if this is earlier than the physical end-of-tape position. This setting is invalid with CDScheck(None).

TERMerr

optionally, specifies whether the inventory of an MVC is to terminate when it encounters the first inconsistency between the contents of the MVC and the VTVs that the CDS indicates are on the MVC. Such inconsistencies are listed via message SLS6935E, SLS6936E, or SLS6938E.

NO: The inventory of an MVC is not to terminate when it encounters the first inconsistency between the contents of the MVC and the VTVs that the CDS indicates are on the MVC. This is the default.
YES: The inventory of an MVC is to terminate when it encounters the first inconsistency between the contents of the MVC and the VTVs that the CDS indicates are on the MVC. This setting is invalid with CDScheck(None).

Return Codes

The INVENTRY command includes the following return codes:

0 indicates that all requested updates completed successfully.
4 indicates that one or more errors were found. Errors are listed via message SLS6935E, SLS6396E, SLS6938E, SLS6939E, SLS6940E or SLS6941E.
8 indicates that one or more errors were found that are not specific to INVENTRY processing. For example, ECAM errors.

Inventory Report

The following figure shows an example of an INVENTRY report produced by the following command:

INVENTRY MVC(021549)

In this example, the customer wishes to list all VTVs on MVC 021549 without cross-checking the VTVs found with the information recorded in the CDS.

In the sample output, each VTV found on the inventoried MVC is listed in message SLS6933I.

The LIBGen command decompiles the hardware configuration, VOLPARM, VAULT and LOGFILE information from the Control Data Set and creates a set of LIBGEN macros that reflects that information. The LIBGen decompile utility can be used to generate an initial set of LIBGEN macros that can be modified when you are adding new hardware to your installation that requires the creation of a new CDS.

Refer to Oracle's ELS publication Configuring HSC and VTCS for detailed information about when to use this utility and how it functions.

Syntax

Figure 3-92 shows LIBGen command syntax.

Figure 3-92 LIBGen command syntax

Surrounding text describes Figure 3-92 .

Parameters

As shown in Figure 3-92, the LIBGen command includes the following parameters:

TAPELESS

Optionally, provides a method to generate CDSCREat syntax from a CDS that currently contains library definitions, or to create LIBGEN macro syntax from a CDS currently defined as tapeless.

NO: Create CDSCREat syntax from a CDS that currently contains library definitions.
YES: Create LIBGEN macro syntax from a CDS currently defined as tapeless.

If the TAPEPLESS parameter is omitted, the default is based on the input CDS; that is, a tapeless CDS generates CDSCREat syntax and a CDS with library definitions generates LIBGEN macro syntax. When TAPELESS(NO) is specified for a tapeless CDS, ACSs and LSMs must be defined prior to using the LIBGEN macros to define a new CDS.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the LIBGen JCL:

SLSLIBGN

output data set to accommodate the LIBGEN created by the utility.

The data set has these characteristics: LRECL=80, fixedblocked format (multiple of 80). The data set can be assigned to print or to output to a DASD. It may be assigned to DUMMY if only the SLSPRINT output is desired.

SLSPARM

Output VOLPARM card images from CDS.

SLSPARM is required when VOLPARM records exist in the CDS. If the SLSPARM DD is not coded in the JCL, message SLS0212I is issued and the utility ends with a return code 4.

SLSSET

Output CDSCREAT, SET VOLPARM, SET VAULT or SET VAULTVOL, and/or SET LOGFILE control statements from the CDS. If the LIBGEN utility attempts to output one of the above types of control statements and the SLSSET DD statement is missing, a message SLS0212I is issued. If the statement to be produced is CDSCREAT, the utility terminates with a return code of 8; otherwise, processing continues and a return code of 4 is generated.

Output

LIBGen command output includes the following:

a valid LIBGEN file matching the existing control data set. The output file has the following characteristics:
- All station and drive addresses are 4character addresses.
- In cases where multiple parameters point to the same label statement, the utility duplicates the statement with a unique label and points each parameter to a different, although identical statement.
- Labels generated in the output LIBGEN are listed in Table 3-6, below.
- If an EJect password exists, it is not displayed. Instead, the following line is displayed:
  
  EJCTPAS=????????
messages associated with error conditions resulting from an unsuccessful execution of the utility.

DRIVE	`Daallpph`	`aa` indicates the ACSid, `ll` indicates the LSMid, `pp` indicates the decimal panel number, and `h` indicates the hexadecimal host index value, beginning with zero.

LMUPDEF

Interfaces:

Console or PARMLIB
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The LMUPDEF command specifies the definition data set that contains network LMU attachment (LMUPATH) statements.

If a definition file is changed by a LMUPDEF operator command, and if the change is to be permanent, you must update PARMLIB before restarting the HSC.

If the definition file is to be modified for a given shift or application, remember that the new definition remains in effect until another definition is loaded or the HSC is recycled. The definition file then reverts to the PARMLIB specification. Thus, LMUPDEF can be used to temporarily change a definition file.

Note:

Definition commands issued on one host are in effect only on that host. If different hosts use the same definition data set, the LMUPATH parameter statements are shared by those hosts.
If you issue multiple LMUPDEF commands or statements, the last one processed is currently active. You can determine which LMUPDEF statement is active by entering the Display LMUPDEF command.

Syntax

Figure 3-93 shows LMUPDEF command syntax.

Figure 3-93 LMUPDEF command syntax

Surrounding text describes Figure 3-93 .

Parameters

As shown in Figure 3-93, the LMUPDEF command includes the following parameters:

DATASET(dataset-name) or DSN(dataset-name)

specifies the name of the data set containing the LMUPATH statements to be processed and, optionally, an OPTION TITLE statement.

dataset-name indicates the name of the data set containing the LMUPATH address parameters. If the data set name includes a member name, dataset.name must be enclosed in quotes. For example:

DATASET(&rsquor;YOUR.DSN(MEMBER)')

Note:

The definition data set may contain VOLATTR, UNITATTR, TAPEREQ, LMUPATH, and OPTION TITLE statements, but only LMUPATH and OPTION TITLE statements are processed.
If any other statement is encountered, an error message is issued and the statement is ignored.
See "OPTION TITLE Control Statement" for more information about the OPTION TITLE control statement.

VOLume(volser)

optionally, specifies the serial number of the DASD volume on which the data set resides. This parameter is optional. Specify the VOLume parameter if the data set is not cataloged, or if a data set on a volume other than the volume indicated by the catalog is to be used.

volser indicates the volume serial number for the definition data set.

UNIT(unit-name)

optionally, specifies the unit where the definition data set is located.

unit-name indicates the unit name. If the definition data set is not cataloged and this parameter is omitted, a unit name of SYSALLDA is the default.

HOSTID(host-id)

optionally, limits the execution of this control statement to the specified hosts. If one of the specified host-ids matches the host executing this control statement, the control statement is executed for that host. Otherwise, it is ignored. If this parameter is omitted, the control statement is executed on all hosts.

This parameter is valid only for use in PARMLIB, so that multiple systems can share a PARMLIB member containing TAPEREQ, VOLATTR, UNITATTR, or LMUPATH statements for different releases of HSC. If entered from the console, message SLS0018I is issued.)

hostid indicates the name of one or more hosts from which to execute this control statement. Multiple hosts must be separated by commas.

LMUPATH Control Statement

The LMUPATH control statement defines network LMU/Library Controller (LC) attachments. It is loaded by the LMUPDEF command.

Note:

If you are using the SL3000 or SL8500 partitioning feature, the PARTID parameter connects to a specific partition defined by the SL3000 or SL8500 library for the HSC host group. Refer to Oracle's ELS publication Configuring HSC and VTCS for information about how to use the partitioning feature.

Syntax

Figure 3-94 shows LMUPATH control statement syntax.

Figure 3-94 LMUPATH control statement syntax

Surrounding text describes Figure 3-94 .

Parameters

As shown in Figure 3-94, the LMUPATH control statement includes the following parameters:

ACS(aa)

specifies the ACS name.

aa indicates the decimal ACSid value (00 through 99) to identify the LMU(s) used to communicate with a HSC.

LMUADDR

identifies an LMU/Library Controller (LC) by host name or IP address, for each ACS. To designate a single LMU/LC environment, specify one IP address or host name. To specify a dual LMU/LC environment or a dual IP connection to an SL8500, enter an additional IP address and/or host name.

The HSC automatically detects the type of connection, dual LMU for a 9330 or dual IP for an SL8500 library.

Users can intermix host name and IP addresses in one LMUPATH control statement. Each parameter entered must represent a different IP address.

lmu-hostname: a host name for the TCP/IP connection. The host name can be up to 24 characters long. The first character must be alphabetic.
nnn.nnn.nnn.nnn: an IP address for the LMU/LC. A maximum of 40 IP addresses can be specified.

PARTID(00n)

defines a partition ID for each ACS.

00n indicates a partition ID from 001 to 999.

All three characters must be entered for the partition ID.
For this release, only IDs 001 through 008 are supported.

Note:

A partitioned SL3000 or SL8500 cannot use the multiple TCP/IP connection feature since partitioning applies only to a single SL3000 or SL8500 box.

PING(tt)

specifies the number of minutes in between requests sent from the HSC to the LMU. These requests are to keep the connection active, which prevents a firewall from closing the connection due to inactivity.

tt indicates the time in minutes from 00-99. The default is 5 minutes if this parameter is not defined, and entering 00 turns off this feature.

LOGUTIL

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The LOGUTIL command initiates the CDS recovery process for VTCS. It is used in the following scenarios:

The CDS has become unusable or corrupt and MVCs used since the date of the CDS backup need to be identified for MVCAUDIT purposes.
A VTSS has suffered a catastrophic data loss.

LOGUTIL calls the module that analyzes the input log files, and calls a recovery module to perform the appropriate recovery actions. Additionally:

The LOGUTIL FOR_LOSTMVC statement recovers VTVs that resided on a lost or damaged MVC.
The LOGUTIL GENAUDIT statement initiates a re-synchronization of the CDS to VSM via MVCAUDIT statements.
The LOGUTIL_LOCATE_VTV statement recovers older versions of VTVs.
The LOGUTIL UNDELETE statement recovers deleted VTVs.

Syntax

Figure 3-95 shows LOGUTIL command syntax.

optionally, specifies an ending time for logged events.

hh:mm:ss indicates the ending time. The default is 00:00:01.

COMMANDS(ddname)

optionally, specifies the DD name of a data set that contains recovery commands.

ddname indicates the DD name.

LOGUTIL FOR_LOSTMVC Statement

The LOGUTIL FOR_LOSTMVC statement recovers VTVs that resided on lost or damaged MVCs.

Syntax

Figure 3-96 shows LOGUTIL FOR_LOSTMVC statement syntax.

Figure 3-96 LOGUTIL FOR_LOSTMVC statement syntax

Surrounding text describes Figure 3-96 .

Parameters

As shown in Figure 3-96, the LOGUTIL FOR_LOSTMVC statement includes the following parameters:

MVC(volser, volser-range, or volser-list)

specifies the MVC(s) to be recovered. You can specify a maximum of 1000 MVCs.

volser, volser-range, or volser-list indicates the volser, volser range, or volser list to be processed.

VTV(volser, volser-range, or volser-list)

optionally, specifies specific VTV(s) to be recovered. You can specify a maximum of 300,000 MVCs.

Specified VTVs must reside on one or more of the recovery MVCs to be processed. When this parameter is coded, only VTVs specified are recovered (if they exist on the recovery MVCs).

volser, volser-range, or volser-list indicates the volser, volser range, or volser list to be processed.

This parameter behaves as a filter. If VTVs are specified that are not on the specified MVCs, they will not be recovered and will not be listed in the report output.

SCRATCH

optionally, specifies to specify scratch VTVs. By default, scratch VTVs are not processed as part of the recovery.

COMMANDS(ddname)

optionally, specifies the DD name of a data set that includes the recovery commands created when the COMMANDS parameter is specified on the LOGUTIL command.

ddname indicates the DD name.

LOGUTIL GENAUDIT Statement

The LOGUTIL GENAUDIT statement initiates a re-synchronization of the CDS to VSM through MVCAUDIT statements that are generated when the COMMANDS parameter is specified with the LOGUTIL command. The LOGUTIL GENAUDIT statement identifies MVCs for input to MVCAUDIT.

Syntax

Figure 3-97 shows LOGUTIL GENAUDIT control statement syntax.

Figure 3-97 LOGUTIL GENAUDIT statement syntax

Surrounding text describes Figure 3-97 .

Parameters

As shown in Figure 3-97, the LOGUTIL GENAUDIT statement includes the following parameters:

COMMANDS(ddname)

optionally, specifies the DD name of a data set that includes the recovery commands created when the COMMANDS parameter is specified on the LOGUTIL command.

ddname indicates the DD name.

The GENAUDIT COMMANDS parameter works with the LOGUTIL COMMANDS parameter as follows:

If you specify LOGUTIL COMMANDS, the GENAUDIT statement outputs recovery commands to the specified data set even if you did not specify GENAUDIT COMMANDS.
If you specify COMMANDS on both LOGUTIL and GENAUDIT, recovery commands are only output to the GENAUDIT COMMANDS data set.

LOGUTIL LOCATE_VTV Statement

The LOGUTIL LOCATE_VTV statement recovers a non-current version of a VTV.

Syntax

Figure 3-98 shows LOGUTIL LOCATE_VTV control statement syntax.

Figure 3-98 LOGUTIL LOCATE_VTV statement syntax

Surrounding text describes Figure 3-98 .

Parameters

As shown in Figure 3-98, the LOGUTIL LOCATE_VTV control statement includes the following parameters:

VTV(volser, volser-range, or volser-list)

specifies specific VTV(s) to be recovered. You can specify a maximum of 1000 VTVs.

volser, volser-range, or volser-list indicates the volser, volser range, or volser list to be processed.

COMMANDS(ddname)

optionally, specifies the DD name of a data set that includes the recovery commands created when the COMMANDS parameter is specified on the LOGUTIL command.

ddname indicates the DD name.

The LOCATE_VTV COMMANDS parameter works with the LOGUTIL COMMANDS parameter as follows:

If you specify LOGUTIL COMMANDS, the LOCATE_VTV statement outputs recovery commands to the specified data set even if you did not specify LOCATE_VTV COMMANDS.
If you specify COMMANDS on both LOGUTIL and LOCATE_VTV, recovery commands are only output to the LOCATE_VTV COMMANDS data set.

VERSION(-nn)

optionally, specifies the version of the VTV to recover.

-nn indicates the version. Valid values are -1 to -99. The default is VERSION(-1), which is one version older than the current version.

Note:

VERSION is mutually exclusive the DATE and TIME parameters.

DATE(yyyy-mm-dd)

optionally, specifies the date of the VTV version to recover. If you specify DATE, you must also specify TIME.

yyyy-mm-dd indicates the date, by year, month and day.

TIME(hh:mm:ss)

optionally, specifies the time of the VTV version to recover. If you specify TIME you must also specify DATE.

hh:mm:ss indicates the time, in hours minutes and seconds.

LOGUTIL UNDELETE Statement

The LOGUTIL UNDELETE statement recovers deleted VTVs.

Syntax

Figure 3-99 shows LOGUTIL UNDELETE control statement syntax.

Figure 3-99 LOGUTIL UNDELETE statement syntax

Surrounding text describes Figure 3-99 .

Parameters

As shown in Figure 3-99, the LOGUTIL UNDELETE control statement includes the following parameters:

VTV(volser, volser-range, or volser-list)

specifies the VTV(s) to be recovered. You can specify a maximum of 1000 VTVs.

volser, volser-range, or volser-list indicates the volser, volser range, or volser list to be processed.

COMMANDS(ddname)

optionally, specifies the DD name of a data set that includes the recovery commands created when the COMMANDS parameter is specified on the LOGUTIL command.

ddname indicates the DD name.

The UNDELETE COMMANDS parameter works with the LOGUTIL COMMANDS parameter as follows:

If you specify LOGUTIL COMMANDS, the UNDELETE statement outputs recovery commands to the specified data set even if you did not specify UNDELETE COMMANDS.
If you specify COMMANDS on both LOGUTIL and UNDELETE, recovery commands are only output to the UNDELETE COMMANDS data set.

MEDVERfy

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC/VTCS

Description

The MEDVERfy utility performs a Media Verification (MV) by verifying that VTV data can be read on MVCs or VMVCs (ELS 7.1 and VLE 1.2 and above only). For VLE, MEDVERfy ensures that deduplicated VMVCs can be ”rehydrated” (reconstituted).

The utility reports on MVCs that pass or fail verification and also produces XML output.

Syntax

Figure 3-100 shows MEDVERfy command syntax.

Figure 3-100 MEDVERfy command syntax

Surrounding text describes Figure 3-100 .

Parameters

The following three, mutually exclusive, keyword parameters identify the MVCs to be verified:

MVCPOOL(name)

optionally, specifies an MVCPOOL containing MVCs requiring data verification. An undefined MVCPOOL value aborts the utility with RC 8.

name indicates the MVC pool name.

STORclas(name)

optionally, specifies a storage class for MVCs requiring data verification. Based on time of last verify and/or any frequency specified on the command, the utility selects the best MVC candidates for verification processing.

An undefined STORclas value aborts the utility with RC 8.

name indicates the storage class name.

MVC(volser, vol-range, or vol-list)

optionally, specifies a list or range of MVCs to be verified. For individual MVCs whose volser falls outside those defined in the CDS, the utility aborts with RC 8.

volser, vol-range, or vol-list indicates a volser, volser range, or volser list.

Note:

Based on time of last verify and/or any frequency specified on the command, the utility selects the best MVC candidates, within the specified selection criteria, for verification processing.

MAXMVC(nn)

optionally, specifies the maximum number of MVCs that will be processed by a single media verification task.

nn indicates the number of MVCs. Valid values are 1–99. If not specified, the default is 99.

CONMVC(nn)

optionally, specifies the maximum number of MVCs that VTCS concurrently processes for media verification.

nn indicates the number of MVCs. Valid values are 1–99. If not specified, the default is 1.

FREQency(nnnn)

optionally, establishes the verification scheduling interval, in days, that MVCs are to be verified. To be selected for verification, the number of days since the MVC's last verify date must be greater than the number of days specified.

nnnn indicates the interval, in days. Valid values are 1-9999. There is no default. If not specified, the MVC's last verify date, alone, is used for selecting MVCs to verify.

TIMEOUT(nnnn)

optionally, specifies the allowable time, in minutes, for the media verification utility to run.

nnnn indicates the allowable time, in minutes. Valid values are 1-9999. There is no default. If TIMEOUT is not specified, then there is no limit on utility run time.

Note:

Similar to RECLAIM processing, if any MVCs are being processed when the TIMEOUT value is reached, MEDVERfy completes processing on those MVCs, and then stops.

MEDVERfy Reports

The following figure shows an example of a Media Verify report that indicates successful verification for MVC DMV100:

Example 3-49 MEDVERfy report (1 of 2)

Media Verify - -----------Media Verify request 6-----------
Media Verify - 1 MVC(s) selected for processing
MVC DMV100 - verifying media
MVC DMV100 - verify complete
No exceptions to report
 
SLS0155I Condition code for utility function is 0

The report also lists MVCs not selected for MV processing under certain conditions. For example, in the following report, MVC DMV800 is skipped because it was mounted during verification selection:

Example 3-50 MEDVERfy report (2 of 2)

MEDVER MVC(DMV100,DMV800) CONMVC(1) TIMEOUT(180)

MVC DMV800 skipped, is mounted

Media Verify - -----------Media Verify request 21-----------
Media Verify - 1 MVC(s) selected for processing
MVC DMV100 - verifying media
MVC DMV100 - verify complete
No exceptions to report
 
No exceptions to report
SLS0155I Condition code for utility function is 0

MERGEcds

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE service level only

Description

Use the MERGEcds command to do the following:

Add or Change a configuration to reflect new ACSs or LSMs.
Consolidate multiple CDSs into one CDS.
Divide one CDS into multiple CDSs. MERGEcds copies volume information from each old CDS into the new CDS.
Merge multiple ACSs into one ACS.
Divide one ACS into multiple ACSs.
Modify an ACSid and/or LSMid in order to renumber ACSs and LSMs.
Modify VTSS names.
Remove virtual or vault data from the CDS.
Change the number of slots reserved for vaulted volumes.

Note:

Before using MERGEcds, refer to Oracle's ELS publication Configuring HSC and VTCS for detailed procedures used to run the utility.

Syntax

Figure 3-101 shows MERGEcds command syntax.

Figure 3-101 MERGEcds command syntax

Surrounding text describes Figure 3-101 .

Parameters

As shown in Figure 3-101, the MERGEcds command includes the following parameters:

VALIDate

optionally, specifies to only validate that the configurations to be reconfigured or merged are compatible, but not perform the operation. MERGEcds VALIDate reports any duplicate, in-transit, and errant volumes.

ALL

optionally, specifies to copy volume information for all ACSs and VTSSs from the "from" CDS to the "to" CDS. You can also specify the ALL parameter to convert a CDS to extended format.

For a CDS merge, the ACS ID and LSM IDs, and VTSS names must match.
If you are using VTCS, MVCs that are in the source (input) CDS but are not configured in the target (output) CDS, must be empty. An MVC is considered empty if it contains no current VTVs and, if previously used, has been drained.

Note:

ALL and SLSMERGE DD are mutually exclusive. If you do not specify ALL, MERGEcds reads the parameters specified on the SLSMERGE control statement. These parameters specify the ACSs, LSMs, VTSSs, and Vaults whose volume information you want to merge or reconfigure. See "SLSMERGE Control Statement" for more information.

DELVirt

optionally, specifies that VTV and MVC volume information is not copied to the ”to” CDS if both of the following are true:

The VTVs and MVCs defined in the "from" CDS are either uninitialized or empty.

An empty VTV is not VTSS resident and has no current MVC copies. An empty MVC contains no current VTVs and does not have an assigned STORCLAS. An MVC is empty when %USED is 0% and %AVAIL is 100% on an MVC Report or Q MVC display.

Refer to Oracle's ELS publication Managing HSC and VTCS for instructions for removing MVCs from the pool.
The uninitialized or empty VTVs and MVCs in the "from" CDS are not defined in the "to" CDS. That is, no duplicate volsers exist.

DELVirt has no effect unless ALLVIRT is specified on the SLSMERGE control statement.

NOMSG

optionally, suppresses message SLS4245I, which displays the volser of an MVC or VTV that was not copied to the ”to” CDS.

NOMSG has no effect unless DELVirt is specified on the MERGECDS control statement and ALLVIRT is specified on the SLSMERGE control statement.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the MERGEcds JCL:

SLSFCNTL: specifies the current primary copy of the ”from” HSC CDS.
SLSFCTL2: specifies the secondary copy of the CDS, if one is defined.
SLSFSTBY: optionally, specifies the standby copy of the CDS, if one is defined.

Note:

If more than one of these statements are present, HSC determines the primary CDS from the Database Heartbeat (DHB) record of the ”from” CDS. The ”from” CDS is not modified. If a single CDS (SLSFCNTL) is specified, ensure that it is the primary CDS. No DHB validation occurs.

SLSMERGE Control Statement

The SLSMERGE control statement specifies the "from" and "to" ACSs, LSMs, or Vaults to use for a merge, and enables you to rename a VTSS in the Resident VTSS field.

Note:

The SLSMERGE control statement is optional and is mutually exclusive with the MERGEcds ALL parameter.
If you use SLSMERGE control statements, you must include MERGE statements that account for all data in the ”from” CDS.

For example, if your ”from” CDS contains real, virtual, and vault data, you must supply a control card for each of these types to specify whether they are to be copied to the ”to” CDS. If you do not want a particular type of data to be copied to the ”to” CDS, issue the appropriate NO parameter (NOREAL, NOVIRT, or NOVALT) to exclude it.

Syntax

Figure 3-102 shows SLSMERGE control statement syntax.

Figure 3-102 SLSMERGE control statement syntax

Surrounding text describes Figure 3-102 .

Parameters

As shown in Figure 3-102, the SLSMERGE control statement includes the following parameters:

Caution:

The ”real” parameters (FACS, TACS, FLSM, TLSM) and ”vault” parameters (FVAULT, TVAULT) act as selection criteria, while the ”virtual” parameters (FVTSS, TVTSS) act only as rename criteria.

Parameters (Real Volumes)

For REAL volumes, the following parameters apply:

FACS(acs-id)

specifies the ”from” ACS.

TACS(acs-id): specifies the ”to” ACS.

FLSM(lsm-id)

specifies the ”from” LSM.

TLSM(lsm-id): specifies the ”to” LSM.

ALLREAL

Merge all real data only.

NOREAL

Do not merge real data.

Parameters (CDS Containing Virtual Data)

If the CDS contains VIRTUAL data, the following parameters apply:

FVTSS(vtss-name)

specifies the ”from” VTSS name.

TVTSS(vtss-name): specifies the ”to” VTSS name.

You cannot use MERGEcds to remove data for certain VTSSs from the CDS.

FVTSS and TVTSS act only as rename criteria. When these parameters are specified, ALLVIRT is implied.

For example:

MERGE FVTSS(VTSS18) TVTSS(VTSS17)

In this example, all VTV records are copied to the new CDS, but the Resident VTSS field is changed from VTSS18 to VTSS17. All VTSSs not specified in these statements are automatically merged to the same-named VTSS in the new CDS.

ALLVIRT

Merge all virtual data only.

NOVIRT

Do not merge virtual data.

Parameters (CDS Containing VAULT Data)

If the CDS contains VAULT data, the following parameters apply:

FVAULT(vault-name)

specifies the ”from” vault.

TVALT(vault-name): specifies the ”to” vault.

ALLVALT

Merge all vault data only.

NOVALT

Do not merge vault data.

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The MGMTDEF command loads the following control statements from a specified definition data set:

MGMTclas
MIGRSEL
MIGRVTV
MVCATTR
STORclas
STORLST
STORSEL
VTSSLST
VTSSSEL

Note:

When HSC/VTCS is active and the MGMTDEF command is issued to re-load MGMTclas control statements, the 'changed' control statements only affect newly created VTVs. Additional action is required to apply the changes to existing VTVs.

Syntax

Figure 3-105 shows MGMTDEF command syntax.

Surrounding text describes Figure 3-105 .

Parameters

As shown in Figure 3-105, the MGMTDEF command includes the following parameters:

DATASET(dataset-name) or DSN(dataset-name)

specifies the definition data set that contains the MGMTclas and STORclas statements to load.

dataset-name indicates the data set name.

VOLume(volser)

optionally, specifies the DASD volume where the definition data set resides. This parameter is optional, unless the data set is not cataloged, or the data set resides on a volume other than the volume indicated by the catalog.

volser indicates the DASD volser.

UNIT(unitname)

optionally, specifies the DASD device where the definition data set resides.

unitname indicates the DASD unit name. If the definition data set is not cataloged and this parameter is omitted, the unit name defaults to SYSALLDA.

HOSTID(host-id)

optionally, specifies the host for execution of the MGMTDEF command. This parameter is only valid when MGMTDEF is specified as a PARMLIB control statement.

host-id indicates the name of one or more hosts from which to execute the MGMTDEF command. Multiple hosts must be separated by commas.

MGMTclas Control Statement

The MGMTclas control statement defines a VSM Management Class. It is loaded by the MGMTDEF command.

Note:

By default, advanced VSM management features are automatically enabled. The FEATures command, included in previous ELS releases to enable these features, is no longer valid.
ELS includes parameters designed to improve migration control. If you choose not to use these features, refer to Oracle's ELS publication Legacy Interfaces Reference for information about existing legacy MGMTclas parameters.
When HSC/VTCS is active and the MGMTDEF command is issued to re-load MGMTclas control statements, the 'changed' control statements only affect newly created VTVs. Additional action is required to apply the changes to existing VTVs.

For example, If you change the IMMDELAY value, you must recycle the HSC to apply the change to existing VTVs. If you change the MIGpol value from one storage class to two, you must recall the VTV to allow for creation of the second migrated copy.

Syntax

Figure 3-106 shows MGMTclas control statement syntax.

Figure 3-106 MGMTclas control statement syntax

Surrounding text describes Figure 3-106 .

Parameters

As shown in Figure 3-106, the MGMTclas command includes the following parameters:

NAME(mgmt-class-name)

specifies the name of the Management Class.

mgmt-class-name indicates the Management Class name. This name must be one to eight alphanumeric characters beginning with an alpha character and must follow SMS naming conventions.

ACSlist(acs-id or acs-id,acs-id)

optionally, specifies the ACSs from which RTDs and MVCs are selected. If not specified, the default is the ACS specified on the CONFIG DEFLTACS parameter.

See DUPlex, below, for information about using the DUPlex and ACSlist parameters.

acs-id or acs-id,acs-id indicates either one or two ACS IDs. An ACSid is a two digit decimal ACS identifier from 00-99.

ARCHAge(nnn)

optionally, specifies the age (in days) of a VTV before it is archived as specified by ARCHPol. If you specify ARCHAge, you must specify ARCHPol.

This parameter is optional; there is no default value. Valid values are 1 to 999.

nnn indicates the VTV age in days.

ARCHPol(stor-class-name or stor-class-list)

optionally, specifies up to four Storage Classes that specify the ACS and media type of the archive MVCs. If you specify:

If you specify one Storage Class, VTCS archives one copy of a VTV.
If you specify multiple Storage Classes (with different ACS values, different MEDIA values, or both), VTCS archives multiple copies of the VTV to different MVCs in different ACSs.
If you specify multiple Storage Classes with identical ACS and MEDIA values, VTCS archives multiple copies of the VTV to the same ACS and media type but to different MVCs.

Note:

Multiple Storage Classes on ARCHPol also affects how VTV recall, MVC space reclamation, and VTV consolidation function.

This parameter is optional; there is no default value. If you specify ARCHPol, you must specify ARCHage.

stor-clas-name1...stor-clas-namen indicates the names of one or more Storage Classes that you defined on the STORclas control statement. Greater than two copies requires you to specify CDSLEVEL(V6ABOVE) or CDSLEVEL(V6ABOVE) on the CONFIG statement.

CONSRC(stor-class-name)

optionally, specifies the Storage Class that species a preference for the source MVC ACS and media for consolidation of VTVs that are migrated and copied to multiple MVC locations or media types. If the MVC in the specified Storage Class is unavailable, and the specified Storage Class is not the last (in order specified in the migration policy), VTCS uses the MVC associated with the last Storage Class. If the MVC in the specified Storage Class is unavailable and the specified Storage Class is the last (in order specified in the MIGpol parameter), VTCS uses the MVC associated with the previous Storage Class (in order specified in the MIGpol parameter).

stor-class-name indicates the name of a Storage Class that you defined on the STORclas control statement.

CONTGT(stor-class-name)

optionally, specifies the Storage Class that determines the output MVC ACS and media for VTV consolidation (executing CONSolid, EXPORT VTV or EXPORT MGMTclas). Note that the media preferencing is in the opposite order of the list of media types specified on the Storage Class.

This parameter is optional; there is no default value. If you do not specify a value for CONTGT, VTCS selects the output MVC as follows:

For single-ACS and dual-ACS configurations, the media selection order for VTV consolidation.
For multiple ACS systems, VTCS selects MVCs from the default ACS specified by the CONFIG DEFLTACS parameter.

stor-class-name indicates the name of a Storage Class that you defined on the STORclas control statement.

DELSCR

optionally, specifies whether VSM deletes scratched VTVs.

NO: Do not delete scratched VTVs (the default).
YES: Delete scratched VTVs unless this would cause a processing delay due to unavailable resources.
FORCE: Delete scratched VTVs and wait for access to any resources that are required. This may cause a processing delay.

Caution:

When you scratch a VTV with DELSCR YES attribute, VSM erases the VTV data at scratch synchronization time, which eliminates the ability ”unscratch” a VTV to recover data!

Also note that when using HSC to perform scratch synchronization, it is possible that a volume that is scratch in the TMC at the beginning of scratch synchronization run and also scratch in the CDS from the previous scratch update run (and thus is in the list for HSC to scratch in the CDS) is accessed by a job during the scratch update run and written to and made non-scratch by the TMS in the TMC. In this case, it is still possible for HSC to scratch the volume because it was in the originally extracted list of volumes to be scratched. Therefore, Oracle strongly recommends that you do not run any jobs that use scratches during HSC scratch synchronization.

See "Scratch Conversion Utility (SLUCONDB)" for more information about HSC scratch synchronization with the Scratch Conversion Utility (SLUCONDB).

Refer to the LCM User's Guide for more information about LCM scratch synchronization with the SYNCVTV function.

DISCARD(nnnn)

optionally, specifies the discard time in hours. This value represents the time after a VTV is dismounted that the VTV is kept in the buffer. After this time value expires, the VTV is preferred for deletion from the VTSS buffer if all required copies of the VTV exist on MVCs.

nnnn indicates the time in hours. Valid values are 0 to 9999. The default is 9999.

When IMMEDmig is specified, DISCARD is not used for immediate migration processing. It is only applicable for AUTO migration requests. If RESTIME is also specified for a VTV, it overrides the DISCARD value.

DUPlex

optionally, specifies whether VSM will migrate two copies of the VTV to two MVCs. DUPlex and MIGpol are mutually exclusive.

NO: Do not duplex the VTV (the default).
YES: Duplex the VTV.

The following table describes possible scenarios using the DUPlex and ACSlist parameters:

Table 3-7 MGMTclas ACSlist/DUPlex Scenarios

DUPlex Setting	ACSlist Setting	Action
`YES`	two ACSs	VSM migrates the VTVs to two MVCs, one in each ACS. (This scenario is the normal one for duplexing to two ACSs.)
`YES`	one ACS	VSM migrates the VTVs to two MVCs in the ACS specified.
`NO`	two ACSs	VSM ignores the `DUPlex` policy and migrates the VTVs to two MVCs, one in each ACS.
`NO`	one ACS	VSM migrates the VTVs to one MVC in the ACS specified.

MIGpol(s1 or s1,s2 or s1,s2,s3 or s1,s2,s3,s4)

optionally, specifies up to four Storage Classes that specify the ACS and media type of migration MVCs. DUPlex and MIGpol are mutually exclusive.

If you specify one Storage Class, VTCS migrates one copy of a VTV.
If you specify multiple Storage Classes (with different ACS values, different MEDIA values, or both), VTCS makes multiple copies the VTV to different MVCs in different ACSs.
If you specify multiple Storage Classes with identical ACS and MEDIA values, VTCS makes multiple copies of the VTV to the same ACS and media type but to different MVCs.

Note:

Multiple Storage Classes on MIGpol also affects how VTV recall, MVC space reclamation, and VTV consolidation function.

This parameter is optional; there is no default value.

s1 or s1,s2 or s1,s2,s3 or s1,s2,s3,s4 indicates the names of up to 4 Storage Classes that you defined on the STORclas control statement. Greater than two copies requires you to specify CDSLEVEL(V61ABOVE) or greater on the CONFIG statement.

Note:

The CONFIG GLOBAL REPLicat parameter specifies when to replicate a VTV (always, or only when changed while mounted).

EEXpol(s1 or s1,s2)

optionally, specifies the storage classes for electronic export.

s1 or s1,s2 indicates a maximum of two Storage Classes that specify the TAPEPLEX parameter. If these storage classes do not specify the TAPEPLEX parameter, an error condition results.

If there are two TAPELEX storage classes, then they must specify different destination TapePlex names.
A warning will be generated if the two TapePlex storage classes are specified with the SYNC=YES parameter. It is only possible to synchronously export to one other TapePlex.
If there is a conflict, electronic export functionality takes precedence over replication with a cluster.
If either one of the storage classes referenced contains the THISPLEX name, then the storage class is silently ignored. This enables common storage class definitions to be applied across TapePlexes.

IMMDELAY(nnnn)

optionally, specifies the immediate migration delay time; the amount of time after VTV dismount that the migration should be queued for action.

This enables VTVs used in multi-step jobs to remain resident for a specified time before being processed for migration.

nnnn indicates the immediate migration delay time in minutes. Valid values are 0 to 9999 (the default).

If IMMDELAY=9999 then immediate migration does not occur. Migration and deletion is handled through auto or command migration.

When this value is specified, MIGRSEL and MIGRVTV have no influence on migration control.

RESTIME and DISCARD parameter values represent buffer management priorities:

If the IMMDELAY value is less than the RESTIME value, keep the VTD in the VTSS as a priority.
If the IMMDELAY value is greater than the RESTIME value but less than the DISCARD value, manage the buffer according to LRU (default state).
If the IMMDELAY value is greater than the DISCARD value, remove the VTD from the VTSS as a priority.

The IMMDELAY parameter is designed to replace the IMMEDmig parameter, described in Oracle's ELS publication ELS Legacy Interfaces Reference. These parameters are mutually exclusive. The following table describes equivalent values:

Table 3-8 IMMDELAY and IMMEDmig Equivalent Values

IMMDELAY or DISCARD Values	Equivalent IMMEDmig Value	Action
`IMMDELAY(1-9998)`	`None`	Delay migration for the specified number of minutes.
`IMMDELAY(9999)`	`IMMED(NONE)`	VSM does not immediately migrate the VTV, but migrates it according to standard VSM migration criteria. `MIGRSEL` and `MIGRVTV` have no influence on migration control.
`IMMDELAY(0)DISCARD(9999)`	`IMMED(KEEP)`	VSM immediately migrates a VTV and keeps a copy resident on the VTSS until the VTV becomes eligible for deletion.
`IMMDELAY(0)DISCARD(0)`	`IMMED(DELETE)`	VSM immediately migrates the VTV and then deletes it from the VTSS.

Note:

If you specify REPlicat YES or YES_SYNC, VTCS defaults to IMMDELAY 0. If you specify REPlicat YES or YES_SYNC in combination with IMMDELAY 9999, VTCS ignores the IMMDELAY parameter without issuing a message. For example:

MGMT NAME(REPIMNO) REP(YES) IMMDELAY(9999)

causes VTCS to use IMMDELAY 0 and perform immediate migration. To suppress immediate migration, add a MIGRVTV MGMTclas(x) IMMDELAY(9999) statement for the management class. See "MIGRVTV Control Statement" for more information.

MAXVtvsz

optionally, specifies the maximum size for VTVs in this Management Class. Valid values for this parameter depend on both the CDS level and the microcode levels of the applicable VTSSs.

400: 400 MB. This is the default.
800: 800 MB. The CDS must be at a E level or above.
2000: 2 GB. The CDS must be at a G level or above.
4000: 4 GB. The CDS must be at a G level or above.

Considerations:

The size of a VTV changes only after it goes through a scratch cycle. Therefore, if you change the Management Class and DISP=MOD, then it will still retain the original size.
If you specify a VTV size that is not supported by the configuration, VTCS issues warning messages and MAXVtvsz defaults to the largest VTV size supported by the configuration.
MAXVtvsz does not apply to VSM2s.
MAXVTVSZ(2000 | 4000) requires VSM4 or VSM5 microcode D02.02.00.00 or VSM3 microcode N01.00.77.00. No installed option is required.

NOMIGRAT

optionally, specifies that VTVs in the Management Class are not candidates for migration, consolidation or export, but are candidates to reside on a tapeless VTSS.

VTSS selection is changed to prefer tapeless VTSSs for VTVs in Management Classes with NOMIGRAT, and to disallow VTVs without NOMIGRAT from VTSSs with no RTDs.

NOMIGRAT is mutually exclusive with ACSLIST, IMMDELAY, DUPLEX, MIGPOL, ARCHAGE, ARCHPOL, RESTIME, CONSRC and CONTGT.

REPlicat

optionally, specifies whether VSM replicates the VTV.

Synchronous replication must be enabled through the CONFIG GLOBAL SYNCHREP parameter. For more information, see "CONFIg GLOBAL Statement".

MGMT NAME(REPIMNO) REP(YES) IMMDELAY(9999)

causes VTCS to use IMMDELAY 0 and perform immediate migration.

To suppress immediate migration, add a MIGRVTV MGMTclas(x) IMMDELAY(9999) statement for the management class. See "MIGRVTV Control Statement" for more information.

NO: Do not replicate the VTV (the default).
YES: Asynchronously replicate the VTV.
YES_SYNC: Synchronously replicate the VTV.

RESTIME(nnnn)

optionally, specifies how long VTCS attempts to keep a VTV as VTSS-resident before becoming a preferred automatic migration candidate.

This parameter is optional; there is no default value. Valid values are 1 to 9999. Value 9999 specifies that the VTVs in this Management Class are resident permanently unless VTSS space management requires VTCS to automigrate the VTV and then delete it from the VTSS.

nnnn indicates the residency time in hours.

RESTIME and IMMEDmig(DELETE) are mutually exclusive. RESTIME takes effect when a VTV is created, and does not apply to a recalled VTV.

VTVPAGE

optionally, specifies that the page size used to store VTV data in the VTSS and on the MVCs. This setting only applies to 400 MB and 800 MB VTVs. If VTVPAGE is not specified on either the MGMTclas statement or the CONFIG GLOBAL statement, the default is STANDard.

STANDARD: standard page size, which is compatible with all VSM3 or VSM4 models and microcode levels.
LARGE: large page size, which can provide improved performance within the VTSS and for migrates and recalls. Large page size requires a G level CDS. For more information on CDS levels, see "CONFIg". For 2 GB VTVs or 4 GB VTVs (MAXVtvsz 2000 or 4000), a VTVPAGE setting of LARGE is always used.

Considerations:

VTVPAGE does not apply to VSM2s. VTVPAGE(LARGE) requires VSM4 or VSM5 microcode D02.02.00.00 or VSM3 microcode N01.00.77.00. No installed option is required.
MGMTCLAS VTVPAGE, if specified, overrides the CONFIg GLOBAL VTVPAGE value. If VTVPAGE is not specified on either the MGMTclas statement or the CONFIg GLOBAL statement, the default is STANDard.
The page size of a VTV can only be changed by a VTV scratch mount. Additional restrictions may also apply for scratch VTVs that were previously resident in a VTSS.
If you specify LARGE and the CDS level and/or VTSS microcode do not support LARGE, VTCS issues warning messages and VTVPAGE defaults to STANDard.
If you specify STANDard for 2 GB or 4 GB VTVs VTCS issues warning messages and defaults to LARGE.
Creating VTVs with large pages makes these VTVs unreadable in configurations that do not support large VTV pages.
The VTVPAGE valued specified for this Management Class overrides the global value specified on the CONFIg utility.

WRITE

optionally, specifies the VTSS-resident VTV VOLSAFE policy as follows:

MANY

specifies no VOLSAFE write protection. This is the default.

ONCE

specifies partial (write once) VOLSAFE protection. After the VTV is non-scratch, it cannot be overwritten or appended while it is VTSS-resident.

APPEND

specifies full VOLSAFE protection. This is only supported for VSM6 systems.

VTV data can be appended once non-scratch.
Data cannot be overwritten.

The Display VTV command and VTVRPT report will indicate that the VTV is write-append protected.

VTVs with full VOLSAFE protection can only be scratched with RACF ALTER authority. Use the following RACF commands to set RACF authority:

RDEFINE TAPEVOL volser UACC(NONE)
PERMIT volser CLASS(TAPEVOL) ID(userid) ACCESS(ALTER)

EDLTeexp

optionally, specifies whether pending Electronic Export VTVs are candidates for early deletion. The VTVs will only be deleted if all CLINKs to the remote Tapeplex are not operational. The EDLTeexp option requires that the EEXPOL and MIGPOL policies be set for the management class.

Note:

For the early delete VTVs to be electronically exported, you must run the VTCS RECONCIL utility after the remote Tapeplex CLINKs are varied ONLINE.

MIGRSEL Control Statement

The MIGRSEL control statement controls migration request settings for a Storage Class, VTSS, and/or host. It is loaded by the MGMTDEF command.

Syntax

Figure 3-107 shows MIGRSEL control statement syntax.

Figure 3-107 MIGRSEL control statement syntax

Surrounding text describes Figure 3-107 .

Parameters

As shown in Figure 3-107, the MIGRSEL control statement includes the following parameters:

STORclas(stor-clas-name)

optionally, specifies a Storage Class to which the migration settings apply. If you do not specify a Storage Class, the statement applies to all Storage Classes.

stor-clas-name indicates the Storage Class name you defined on a STORclas control statement.

VTSS(vtssname)

optionally, specifies a VTSS to which the migration settings apply. If you do not specify a VTSS, the statement applies to all VTSSs.

vtssname indicates the VTSS name.

HOST(host-id)

optionally, specifies one or more hosts to which the migration settings apply. Any hosts not specified on this parameter ignore the settings. If you do not specify one or more hosts, the settings apply to all hosts.

host-id indicates a host identifier (maximum 8 characters).

FUNCtion

optionally, specifies the type of migration to which the settings apply:

IMMED

migrations resulting from either of the following:

MGMTclas IMMEDmig(KEEP)
MGMTclas IMMEDmig(DELETE)

AUTO

automatic migrate to threshold migration processing.

RECLAIM

migrations resulting from MVC DRAIN or RECLAIM requests.

DEMAND

migrations resulting from a MIGRATE command or utility (demand migrations).

IMMWAIT(nnn)

optionally, makes the MIGRSEL rule sensitive to the state of the current immediate migration work load. The specified value provides an immediate migration wait time or age, in minutes, that this MIGRSEL migration rule will apply to. This value is compared against the amount of time VTVs have been waiting for immediate migration to a particular storage class. If the amount of time (minutes) that VTVs have been waiting is less than or equal to the IMMWAIT value the MIGRSEL rule will apply.

nnn indicates the immediate migration wait time or age, in minutes. Valid values are 0 to 999. The default is 999.

The default value of 999 makes the rule apply to all VTV wait times.
A value of zero is used for applying MIGRSEL rules if immediate migration is not active.

SCHPREF(n)

optionally, preferences automatic and immediate migration per storage class. MIGRSEL VTSS and HOST allow you to specify the VTSS and host to which the preferencing applies.

n indicates the preferencing value. Valid values are 0 to 9. The default is 0.

Higher values can produce quicker migration times, but may not optimize MVC usage.
Lower values may produce slower migration times, but may optimize MVC usage.

The MIGRSEL SCHPREF setting may be affected by the number of RTDs available, the SCHLIMIT setting, and the GLOBAL MAXMIG parameter for the VTSS.

SCHLIMIT(nn)

optionally, de-preferences migration per Storage Class.

nn indicates the preferencing value. Valid values are 0 to 99. The default is 99, which indicates no limit, up to the VTSS MAXMIG value.

Lower values de-preference migration, and you can specify automatic, immediate, demand, and reclaim migrates. Lower values can do the following:

Optimize MVC usage.
Preference migration to other Storage Classes.
Limit migration to keep RTDs available for auto recalls.
Reduce MVC swapping when workloads change.

For auto and immediate migration processing, MIGRSEL SCHLIMIT de-preferences migration for the VTSS to storage class relationship. This comparison is not global and only effects requests driven by the individual VTCS host.

For demand migration requests, MIGRSEL SCHLIMIT will cause the request to be held if the scheduling of it would cause the number of globally active migration requests on the VTSS that satisfy the same FUNCTION and STORCLAS selection criteria to be exceeded. The migration requests will be released and an MVC picked once the constraint subsides.

MIGRVTV Control Statement

The MIGRVTV control statement controls individual VTV copies processed by immediate migration. It is loaded by the MGMTDEF command.

This statement defines how the behavior of an individual immediate migrate should be modified depending upon various environmental considerations. The MIGRVTV rules are searched for each immediate migrate instance of a VTV. The first match found for each instance is used to modify the immediate migrate.

Syntax

Figure 3-108 shows MIGRVTV control statement syntax.

Figure 3-108 MIGRVTV control statement syntax

Surrounding text describes Figure 3-108 .

Parameters

As shown in Figure 3-108, the MIGRVTV control statement includes the following parameters:

MGMTclas(mgmt-clas-name)

optionally, specifies a Management Class to which the migration settings apply. If you do not specify a Management Class, the statement applies to all Management Classes.

mgmt-clas-name indicates the name of a Management Class you defined on the MGMTclas control statement.

VTSS(vtssname)

optionally, specifies a VTSS to which the migration settings apply. If you do not specify a VTSS, the statement applies to all VTSSs.

vtssname indicates the VTSS name.

STORclas(stor-clas-name)

optionally, specifies a Storage Class to which the migration settings apply. If you do not specify a Storage Class, the statement applies to all Storage Classes.

stor-clas-name indicates the name of a Storage Class you defined on the STORclas control statement.

INDEPEND

Affected VTVs are independent of any other VTV migrate instance. This is the default and applies to any migrates that do not match a MIGRVTV rule or any rule without an INITIAL or SUBSEQNT parameter.

INITIAL

Affected VTV migrates are scheduled and performed before any migrate instances that match to a rule with the SUBSEQNT parameter.

SUBSEQNT(timeout)

Affected VTV migrates are scheduled and performed after any migrate instances that match to a rule with the INITIAL parameter.

timeout indicates the time in minutes after which the rule expires. This is in addition to any IMMDELAY value applied to the INITIAL migrate instances.

IMMDELAY(time)

optionally, specifies the immediate migration delay time; the amount of time after VTV dismount that the migration should be queued for action. This enables VTVs used in multi-step jobs to remain resident for a specified time before being processed for migration.

This IMMDELAY parameter may be used to override the IMMDELAY value in the management class definition for the VTV as a whole. If the delay exceeds the DISCARD value in the management class, then the migrate will cause an implicit deletion of the VTV copy from the source VTSS.

If a delay time of 9999 is specified by this parameter or the IMMDELAY parameter in the management class, then the specific migrate instance is deleted and must later be serviced using auto/command migration.

nnnn indicates the immediate migration delay time in minutes. Valid values are 0 to 9999 (the default).

Considerations:

If IMMDELAY=9999 then immediate migration does not occur. Migration and deletion is handled via auto/command migration.

When this value is specified, MIGRSEL and MIGRVTV have no influence on migration control.
If IMMDELAY=0 then immediate migration is scheduled immediately.
If IMMDELAY is less than 9999 and DISCARD is greater than IMMDELAY then immediate migration occurs and deletion is deferred to auto/command migration.
If IMMDELAY is less than 9999 and DISCARD is less than or equal to IMMDELAY then immediate migration and immediate deletion occur together.
If auto migration encounters a VTV that has passed its DISCARD time, the VTV is moved to the front of the migration queue, and it will be processed first.

Note:

See "MGMTclas Control Statement" for information about the DISCARD parameter.

MVCATTR Control Statement

The MVCATTR control statement assigns a swap-to RTD device type to an MVC media name. When an error occurs while reading an MVC on an RTD, VTCS may swap the MVC to another RTD to retry the operation.

Syntax

Figure 3-109 shows MVCATTR control statement syntax.

Figure 3-109 MVCATTR control statement syntax

Surrounding text describes Figure 3-109 .

Parameters

As shown in Figure 3-109, the MVCATTR control statement includes the following parameters:

MEDIA(media-name)

specifies the MVC media name to which the attribute is assigned. Only one MVCATTR should be coded for each media-name.

media-name indicates the MVC media name. See Table 3-9.

SWAPTO(device-type)

defines the RTD device type the MVC is swapped to (if possible).

device-type indicates the RTD device type. See Table 3-9.

Table 3-9 Valid MVC Media Names and Compatible SWAPTO RTD Device Types

`T1B000ES`	`TIBE34`

STORclas Control Statement

The STORclas control statement defines a VSM Storage Class. It is loaded by the MGMTDEF command.

This statement can specify whether a VTV copy is to be written to:

An MVC (with required attributes)
The name of a remote TapePlex to which a copy of the VTV is to be exported. It also specifies whether a storage class uses partitioned media.
The subsystem name of a VLE.

Syntax

Figure 3-110 shows STORclas control statement syntax.

Figure 3-110 STORclas control statement syntax

Surrounding text describes Figure 3-110 .

Parameters

As shown in Figure 3-110, the STORclas control statement includes the following parameters:

NAME(stor-clas-name)

specifies the name of the Storage Class.

stor-clas-name indicates the Storage Class name. This name must be 1 to 8 alphanumeric characters beginning with an alpha character and must follow SMS naming conventions.

ACS(acs-id)

optionally, specifies the ACSs from which RTDs and MVCs are selected.

acs-id indicates a two digit decimal ACS identifier from 00-99.

STORMNGR(name)

optionally, specifies one of the following:

VLE subsystem name
remote library

name indicates the Storage Manager name:

For VLEs, this value must match the VLE Subsystem Name.
For remote libraries, this value must match a TapePlex name defined on the SMC TAPEPLEX NAME parameter.

For more information, refer to Oracle's ELS publication Configuring the Host Software for VLE.

You can specify both STORMNGR and ACS parameters to restrict selection of MVCs to the library in the remote TapePlex with the designated ACS number.

VLEDELET

optionally, control when deletion of the VTV from the VLE occurs.

DELAY: The deletion of the VTV from the VLE will be delayed until the vMVC is mounted for migration. DELAY is the default.
RECLAIM: The deletion of the VTV from the VLE will be done when the RECLAIM utility is run against the vMVC.

Caution:

The current CDS backup can no longer be used as a DR baseline for vMVC content if you use the DRCHKPT utility and/or the CONFIG RECLAIM PROTECT parameter to protect CDS backup content for vMVCs, and then RECLAIM a vMVC for a STORCLAS that specifies VLEDELET(RECLAIM).

MEDIA(list)

optionally, specifies a preference list of MVC media types. This list supersedes the default media selection list. Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

list indicates the preference list of media types.

MVCPOOL(poolname)

optionally, specifies the Named MVC Pool from which volumes are selected. If you do not specify an MVC Pool name, the volumes are selected from the default pool (DEFAULTPOOL).

poolname indicates the name of an MVC Pool that you defined on the MVCPool control statement.

MIGRATE

optionally, for Management Classes with REPLICAT(YES) that reference this Storage Class, specifies the source VTSS (in a Cluster) for VTV migration. This parameter cannot be specified if FROMLST is specified.

RECEIVER: VTSS that receives the replicated VTV (the default), which is the Secondary VTSS in a Primary-Secondary Cluster.
SENDER: VTSS that sends the replicated VTV, which is the Primary VTSS in a Primary-Secondary Cluster.
EITHER: Either VTSS in a Peer-to-Peer Cluster. The source VTSS is randomly selected.

TAPEPLEX(name)

optionally, specifies the name of the TapePlex to which a copy of the VTV is exported. At least one VTSS in the configuration must also specify this name in a CLINK definition.

name indicates the TapePlex name.

SYNC

optionally, specifies whether the exporting of a VTV to TapePlex is performed synchronously.

NO: export of VTV to TapePlex is performed asynchronously. This is the default.
YES: export of VTV to TapePlex is performed synchronously.

If a VTV is specified with two storage classes that specify synchronous exporting, only the first one is honored while the second is exported asynchronously. Likewise, if synchronous replication is specified in the management class, then synchronous exporting is ignored.

FROMLST(vtss-list-name)

optionally, when migrating or exporting to a Storage Class, provides VTCS with a list of VTSSs to source the VTV. FROMLST applies to both Clustered VTSSs and to VLE to VLE connections. For more information, see "FROMLST Parameter Usage".

vtss-list-name indicates the name of a VTSS list (as specified in a MGMTDEF VTSSLST control statement). See "VTSSLST Control Statement" for more information.

INPLACE

optionally, specifies whether Dynamic Reclaim is enabled for this Storage Class. See "Dynamic Reclaim Usage" for more information.

NO: Dynamic Reclaim is not enabled for this Storage Class.
YES: Dynamic Reclaim is enabled for this Storage Class.

DEDUP

optionally, specifies whether VTV data migrated to VMVCs in a VLE is deduplicated.

NO: Do not deduplicate VTVs. This is the default.
YES: Deduplicate VTVs when migrated to VMVCs.

The DEDUP value is a Storage Class attribute that applies to all VMVC mount requests sent to a VLE. DEDUP applies to all migrations that occur for the life of the mount. To change the DEDUP value, the VMVC is dismounted, the DEDUP value is changed, and the VMVC is remounted.

Dynamic Reclaim Usage

Dynamic Reclaim only applies to T10000B and above media (full and full encrypted only) that have been formatted by T10000 drives capable of creating partitions. It requires an H level CDS, VSM5 microcode D02.11.16.00 or later, and T1010000B firmware 1.41a.209 or later.

You can specify Dynamic Reclaim policies at the global, system wide level or on a Storage Class and MVC pool level. Use the VTCS CONFIg RECLAIM statement to set the global policies:

The INPLACE parameter controls the usage of Dynamic Reclaim. Its setting can either be explicitly specified on the STORCLAS statement or inherited from the RECLAIM statement in the VTCS configuration. The default is INPLACE=NO. The setting that is derived for a Storage Class does not force usage of media formatted in either mode. It is acceptable to use this parameter with drives or media that do not support partitioning. Also, any media written in a different mode continues to be a migration target. This helps avoid the need to actively manage the transition when Dynamic Reclaim is enabled. Its effect is to cause new media allocated to the Storage Class to be formatted and written in either standard (INPLACE=NO) or partitioned (INPLACE=YES) mode. The switch can only occur when media is empty.
If a hard switch-over between standard and dynamic reclaim is required, then a lengthy process involving parameter settings (for example, MEDIA on the STORCLAS statement) is required. MVCs must be removed from the MVC pool or set into a read-only state, using MVCMAINT. Also, MVCs formatted in the wrong mode must be drained.
The INPTHRSH parameter specifies the fragmentation level that makes partitioned MVCs eligible for Dynamic Reclaim. When a partitioned MVC's fragmentation falls between the INPTHRSH and THRESH values, it first becomes eligible for Dynamic Reclaim. If no space is freed on the initial reclaim attempt, the reclaim is retried when the fragmentation level has risen significantly. Should the fragmentation level reach the standard THRESHOLD, then a fall-back method of moving VTVs is performed.

VTCS CONFIg RECLAIM statements provide the global defaults for the system. You can override these defaults at the Storage Class and MVCPool level:

The STORCLAS INPLACE parameter specifies whether Dynamic Reclaim is enabled for a Storage Class. Initially, you may wish to specify INPLACE(NO) in the VTCS CONFIg RECLAIM statement and INPLACE(YES) for selected Storage Classes, in order to evaluate the effects of Dynamic Reclaim. Subsequently, if you wish to apply Dynamic Reclaim to all eligible media, you can specify INPLACE(YES) on the VTCS CONFIG RECLAIM statement.
The INPTHRSH parameter on the POOLPARM statement can be used to set a Dynamic Reclaim threshold specifically for this set of MVC media. This is useful when you wish to treat certain MVCs differently from the VTCS CONFIG RECLAIM defaults.

Dynamic Reclaim can be disabled either globally at a system wide level or at the Storage Class level:

To disable Dynamic Reclaim globally, specify INPLACE(NO) in the VTCS CONFIg RECLAIM statement and ensure that any Storage Class definition does not override this setting.
To disable Dynamic Reclaim for one or more Storage Classes, change INPLACE to NO in the Storage Class policy statements.

Note:

Any MVCs that are currently in use for migration will continue in partitioned format. If you wish to stop active MVCs from further migrates, then use the MVCMAINT utility to mark them as read-only. Once the partitioned volumes are empty, they are automatically re-used in non-partitioned mode. An MVC becomes empty either when all VTVs have expired or the MVC has been DRAINed.

STORMNGR and ACS Parameter Interactions

The STORclas statement now enables you to specify both the ACS and STORMNGR parameters. The statement is generally neutral to whether the target is to a local HSC tape library, a VLE or a remote tape library. The interaction of these parameters is as follows:

If neither the ACS or STORMNGR parameters is specified, MVCs are selected from all available.
If only the ACS parameter is specified, the selection of MVCs is restricted to the library serviced by the local HSC with the designated ACS number.
If only the STORMNGR parameter is specified, then selection of MVCs is restricted to the specified VLE or remote library complex. For a remote library complex, this applies only to ACS 0.
If both the ACS and STORMNGR parameters are specified, selection of MVCs is restricted to the library in the remote tapeplex with the designated ACS number.

The ACS and STORMNGR parameters allow the explicit specification of the location of the Storage Class. Whenever possible, use ACS and STORMNGR instead of implicit location selection by using the MVCPOOL and MEDIA parameters.

FROMLST Parameter Usage

If you do not specify FROMLST, the default behavior is as follows:

For Clustered VTSSs, if a copy resides on multiple VTSSs in the cluster, the VTV can be sourced from any available VTSS, which may not be optimal if the VTSS and the connected ACS are geographically distant from each other.
For VLE to VLE connections, if a VTV copy resides on both a VTSS and one VLE and you want to migrate it to a connected VLE, the default is to use the VLE to VLE connection. Similarly, this may not be optimal if the connected VLEs are geographically distant from each other.

Figure 3-111 shows a DR scenario with a local VLE (LOCVLE) and remote VLE (REMVLE) connected to VTSSA. You wish to migrate two VTV copies:

First, a local copy from VTSSA to LOCVLE.
Second, a copy via VLE-to VLE copy from LOCVLE to REMVLE.

Figure 3-111 VLE to VLE Replication (Versus VTSS to VLE)

Surrounding text describes Figure 3-111 .

To make the VTV copies as desired, do the following:

Create a VTSSLST statement to create a VTSS list that contains only VTSSA.

VTSSLST NAME(VSM2VLE) VTSS(VTSSA)
Create a STORCLAS statement that sends a VTV copy to REMVLE.

STORCLAS NAME(FORREMOT) STORMNGR(REMVLE)
Create a MIGRVTV statement that delays the migration copy to REMVLE.

MIGRVTV STOR(FORREMOT) IMMDELAY(360)

The migration delay is 360 minutes to allow the migration to the local site occur first; then the migration to the remote site is by VLE-to-VLE copy. Note that 360 minutes is just an example value, you can specify values of up to 9998 (do not specify 9999, because then the VTV is only migrated via automigration).
Create a STORCLAS statement that sends a VTV copy to LOCVLE.

STORCLAS NAME(FORLOCAL) STORMNGR(LOCVLE) FROMLST(VSM2VLE)

Note that the FROMLST parameter specifies that the local VTV copy is sourced from VTSSA.
Finally, create a MGMTCLAS statement that specifies two VTV copies, one to the local site and one to the remote site:

MGMTCLAS NAME(DRVLE) MIGPOL(FORLOCAL,FORREMOT)

STORLST Control Statement

The STORLST control statement specifies a list of Storage Classes and their corresponding preferencing. It is loaded by the MGMTDEF command.

Syntax

Figure 3-112 shows STORLST control statement syntax.

Figure 3-112 STORLST control statement syntax

Surrounding text describes Figure 3-112 .

Parameters

As shown in Figure 3-112, the STORLST control statement includes the following parameters:

NAME(stor-list-name)

specifies the name of the Storage Class list.

stor-list-name indicates the list name (a maximum of 8 alphanumeric characters).

STORclas(stor-clas-name)

specifies one to ten Storage Classes on the Storage Class list.

stor-clas-name indicates the name of a Storage Class that you defined on the STORclas control statement.

PRIority(order)

a list of priorities corresponding to the Storage Classes specified on the STORclas parameter.

order indicates the specified priority. Valid values are 0 to 9 (highest priority), and the default is 5. You can assign the same priority to multiple Storage Classes. For example, if two Storage Classes both have a priority of 9, VTCS selects randomly from the two. A 0 (zero) priority specifies that VTCS selects the Storage Class only if all other Storage Classes are unavailable (for example, no free MVCs available for write).

The Storage Class list is further qualified by the criteria specified by the MGMTclas and VTSS parameters of the STORSEL statement.

STORSEL Control Statement

The STORSEL control statement defines a Storage Class usage rule that applies to the Storage Class list and its preferencing specified on a referenced STORLST control statement. It is loaded by the MGMTDEF command.

Syntax

Figure 3-113 shows STORSEL control statement syntax.

Figure 3-113 STORSEL control statement syntax

Surrounding text describes Figure 3-113 .

Parameters

As shown in Figure 3-113, the STORSEL control statement includes the following parameters:

FUNCtion(function)

optionally, specifies the VSM function to which the rule applies. Only one function can be specified per statement. If this parameter is omitted, it applies to all functions. If all functions do apply, then it makes economical sense to omit the FUNCtion parameter, thus reducing the number of statements to 25% of what would otherwise need to be coded.

function indicates the function name, as described in the following table:

Table 3-10 STORSEL Functions

Function	Explanation
`SPECIFIC`	Applies to automatic recall of a specific VTV for mounting. The list of Storage Classes is determined by the specified statement. This list influences the list of RTDs eligible to mount the MVC in the Storage Class to recall the VTV.
`RECALL`	Applies to demand recall of a specific VTV for mounting. The list of Storage Classes is determined by the specified `STORLST` statement. This list influences the list of MVC copies of a VTV to select the optimal MVC for recall of the VTV.
`EXPORT`	Applies to export. The list of Storage Classes is determined by the specified `STORLST` statement. This list influences the list of MVC copies of a VTV to select the optimal MVC for export of the VTV.
`CONSOLID`	Applies to consolidate. The list of Storage Classes is determined by the specified `STORLST` statement. This list influences the list of MVC copies of a VTV to select the optimal MVC for consolidation of the VTV

HOST(host-id)

optionally, specifies one or more hosts to which the rule applies. If this parameter is used, any hosts not specified on this parameter ignore the rule. If the parameter is not used, the statement applies to all hosts.

host-id indicates a host identifier (maximum 8 characters).

MGMTclas(mgmt-class-name)

optionally, specifies a Management Class.

mgmt-class-name indicates the name of a Management Class that you defined on the MGMTclas control statement.

VTSS(vtss-name)

optionally, specifies a VTSS.

vtss-name indicates the VTSS name, as follows:

For automatic recalls, the VTSS where the recall is performed.
For all other functions, the VTSS where the VTV previously resided. This may be determined from the VTSS value shown in the Display VTV output.

STORLST(stor-list-name)

specifies a list of Storage Classes and their corresponding preferencing.

stor-list-name indicates the name of a Storage Class list that you defined on the STORLST control statement.

Note:

The Storage Class list specified on the STORLST parameter is further qualified by the criteria specified by the MGMTclas and VTSS parameters.

VTSSLST Control Statement

The VTSSLST control statement specifies a list of VTSSs and their corresponding preferencing. It is loaded by the MGMTDEF command.

VTCS first determines a system priority for each VTSS, based on various factors. For example, whether the VTSS can service the request, whether the required resources are online/available or whether the VTSS is in a compromised state (high DBU).

When more than one VTSS has the highest system priority, VTSSLST priorities can be used to influence which VTSS is used. However, VTSSLST is only considered when there is an obvious choice of VTSSs with equal abilities to service a request.

Syntax

Figure 3-114 shows VTSSLST control statement syntax.

Figure 3-114 VTSSLST control statement syntax

Surrounding text describes Figure 3-114 .

Parameters

As shown in Figure 3-114, the VTSSLST control statement includes the following parameters:

NAME(vtss-list-name)

specifies the name of the VTSS list.

vtss-list-name indicates the list name (a maximum of 8 alphanumeric characters).

VTSS(vtss-name)

specifies one to sixty four VTSSs on the VTSS list.

vtss-name indicates a VTSS name.

PRIority(order)

optionally, lists priorities corresponding to the VTSS names specified on the VTSS parameter.

order indicates the specified priority. Valid values are 0 to 9 (highest priority), and the default is 5. You can assign the same priority to multiple VTSSs.

Within a set of VTSSs with the highest system priority:

If two or more VTSSs have the same highest VTSSLST priority, VTCS selects randomly from the two (according to factors such as DBU and VSM model).
A 0 (zero) priority specifies that VTCS selects the VTSS only if all other VTSSs are unavailable (for example, unavailable due to DBU > 95%, VTSS offline, all RTDs offline, or all VTDs are busy).

Specifying priority zero does not ensure that the VTSS will never be selected. To ensure that the VTSS is never selected, do not specify the VTSS in the VTSS(..) list.

Note:

The VTSS list specified on the VTSSLST parameter is further qualified by:

The function specified on VTSSSEL statement.
The criteria specified by the MGMTclas, VTSS, STORclas, and MVCpool parameters of the VTSSSEL statement.
Other factors such as RTD connectivity.

For example, in scratch allocation, the list of VTSSs is reduced to the VTSSs that can meet Management Class policies (such as REPLICAT(YES)). If the list of VTSSs is reduced to zero, the request fails.

VTSSSEL Control Statement

The VTSSSEL control statement defines a VTSS usage rule that applies to the VTSS list and its preferencing specified on a referenced VTSSLST control statement. It is loaded by the MGMTDEF command.

Note:

VTSSSEL statements are honored only if the VTVs on the MVCs being processed are not resident in a VTSS. If the VTVs are resident, then VTCS ignores the VTSSSEL statement and migrates the VTV from the VTSS where it is resident.

Syntax

Figure 3-115 shows VTSSSEL control statement syntax.

MNTD

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The MNTD command specifies how HSC processes mounts and dismounts of library volumes.

Syntax

Figure 3-118 shows MNTD command syntax.

Figure 3-118 MNTD command syntax

Surrounding text describes Figure 3-118 .

Parameters

As shown in Figure 3-118, the MNTD command includes the following parameters:

AUTocln

controls automated transport cleaning.

OFf

disables the automated cleaning function. OFf is the initial value for the HSC.

ON

enables the following HSC cleaning functions:

the automated cleaning function, which detects when a transport requires cleaning and schedules the mount of a cleaning cartridge. For an LMU at level 22 or above, the cleaning occurs after the next dismount. For all other levels, the cleaning occurs prior to the next volume mount.
the CLean command which is used to schedule the mount of a cleaning cartridge for a specified transport. See "CLean" for more information.

Dismount

specifies whether volumes are to be deleted automatically from the control data set when a dismount is requested in a manual mode LSM for a volume that was mounted by the robot before the LSM was modified offline.

Auto

indicates that volumes are to be automatically deleted from the control data set when a manual dismount is requested for a volume that was mounted by the robot. Auto is the initial value for the HSC.

Manual

directs the HSC to issue a message prompting the operator to decide whether the volume is to be deleted from the control data set when a manual dismount is requested for a volume that was mounted by the robot.

Setting Dismount to Manual is useful when an LSM is modified offline for only a short time. In this case, the operator can choose to not respond to the dismount message and leave the volume mounted on the transport. When the LSM is modified online the HSC redrives the outstanding dismount request, causing the robot to dismount the volume and place it in a storage cell.

Ejctauto

controls automatic ejection of cleaning cartridges that have exceeded their maximum use.

In a multihost environment, the EJctauto setting for a given ACS should be the same on all hosts. EJctauto status is not shared among the HSCs on different hosts.

ON

directs the HSC to automatically eject cleaning cartridges that have exceeded the number of times they can be used (as specified by the MNTD MAXclean or VOLATTR MAXclean parameters). ON is the initial value for the HSC.

MSg

directs the HSC to prompt the operator to either eject an over uselimit cartridge from the ACS or to keep a cleaning cartridge in the ACS.

OFf

directs the HSC to keep an over uselimit cleaning cartridge in the ACS. A message is issued displaying the cleaning cartridge's volser and describing this action.

ACS(acs-id)

optionally, specifies that the EJctauto settings apply only to the specified ACS. If this parameter is omitted, EJctauto settings affect all ACSs.

acs-id indicates a decimal value from 00 to 99 that identifies the ACS. A single digit acs-id can be entered.

Float

specifies whether the HSC is to select a new home cell location when it dismounts a volume that required a passthru when it was mounted.

In multihost environments, the Float setting for a specific ACS should be the same on all hosts. Float status is not shared among the HSCs on different hosts.

ON

directs the HSC to select a new home cell location for the volume in the LSM where the dismount occurs (provided a cell is available). If no cells are available in the new LSM, a location is chosen in the nearest LSM with free cells or the volume can be forced to its original home cell. Setting Float to ON reduces the number of pass-thru operations. ON is the initial value for the HSC.

OFf

directs the HSC to return the volume to its original home cell location when it is dismounted.

Note:

The MNTD Float OFf command is useful for remote ACS/CDS link down situations to avoid control data set integrity issues by making sure cartridges are returned to their original home cell locations. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information about remote libraries.

ACS(acs-id)

optionally, specifies that the Float setting applies only to this ACS. If the ACS parameter is omitted, the Float setting affects all ACSs.

acs-id indicates a decimal value from 00 to 99 that identifies the ACS. A single digit acs-id can be entered.

MAXclean(count)

specifies the maximum number of times a cleaning cartridge is to be used.

The EJctauto setting in effect for the ACS controls how cleaning cartridges are handled when they exceed their maximum use.
In a multihost environment, the MAXclean setting should be the same on all hosts. The MAXclean value is not shared among the HSCs on different hosts.
Follow the cartridge vendor's recommendations for the number of times a cleaning cartridge should be used.

count indicates a decimal value, in the range from 1 through 32767. The initial value for the HSC is 100.

The count value applies to each cleaning cartridge in the library. When a cleaning cartridge is used count number of times, it is not selected if there are cleaning cartridges compatible with the transports in the ACS that have been used less than count number of times. Over uselimit cleaning cartridges may be automatically ejected, depending on the MNTD EJctauto setting.

MMount

specifies whether or not a mount message is issued during manual mode. This enables the operator to retain a manually mounted volume in the control data set.

Delete: generates a manual mode mount message which prompts the operator to respond D to delete the volume from the control data set, or I to ignore the mount request. Delete is the initial value of the HSC.
Reply: generates a manual mode mount message which prompts the operator to reply M to DOM the message and retain the volume in the control data set, or I to ignore the mount request.

Note:

When MNTD MMount(Reply) is specified, the HSC action for a manual mode dismount is determined by the MNTD Dismount setting.

PASSTHRU(count)

specifies the maximum number of passthrus that can occur to allow cartridge archival if SCRDISM(ARCHIVE) is specified.

count indicates the maximum number of passthrus allowed for archival of cartridges. Allowable values are decimal in the range from 1 through 99. The initial value of the HSC is 1.

Scratch

determines how a scratch volume is selected to satisfy a scratch mount request for a manual mode LSM.

Manual: specifies that the operator must select a scratch volume when a scratch mount is requested for a manual mode LSM. Manual is the initial value for the HSC.
Auto: directs the HSC to select a scratch volume when a scratch mount is requested for a manual mode LSM. If Scratch is set to Auto, the HSC manual mount message indicates the cartridge VOLSER and cell location as if it were a request for a specific volume.

SCRDISM

specifies whether or not scratch volumes mounted in a 9310 or 9360 LSM are to be automatically archived to a larger or slower LSM upon dismount.

Note:

9740 LSMs cannot attach to any other type of LSM. Thus, SCRDISM does not affect mounts in ACSs containing 9740s.

CURRENT

indicates that scratch volumes mounted in a 9310 or 9360 LSM are to be dismounted according to the MNTD Float parameter setting. CURRENT is the initial value for the HSC.

ARCHIVE

indicates that scratch volumes mounted in a 9310 or 9360 LSM are to be archived into a larger or slower storage device. Archival occurs only if the number of passthrus does not exceed PASSTHRU. Archival of a cartridge can occur:

from a 9360 to either a 9310 or a 4410
from a 9310 to a 4410.

SCRDISM(ARCHIVE) overrides the MNTD Float parameter setting.

The ARCHIVE parameter does not affect dismounts in ACSs containing 9740 LSMs.

HOSTID(host-id)

optionally, identifies the host associated with the MNTD command. This enables you to restrict certain startup options to a specific host.

If this parameter is not specified, the command is executed by each host that accesses PARMLIB.

hostid indicates the host ID (the SMF system identifier for both JES2 and JES3).

Note:

If the hostid does not match the host executing the command, a message is issued and the command is not processed.

MODify

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The MODify command performs the following functions:

modifies a CAP or an LSM online or offline to all hosts, independent of the issuing host
starts dynamic hardware reconfiguration for a SL3000 or a SL8500 library
adds, deletes, or updates an SL3000 or SL8500 ACS definition in the CDS that was preallocated using the SLILIBRY FUTRACS parameter

Dynamic hardware reconfiguration for the SL3000 and SL8500 libraries represents the portion of Near Continuous Operation (NCO) that enables you to dynamically add or delete drives and expansion panels.

Enter the MODify CONFIG command to activate dynamic hardware reconfiguration.

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information about Near Continuous Operation and dynamic hardware reconfiguration.

Caution:

Before you enter MODify CONFIG, perform a backup of the CDS.

It is possible to remove LSMs from the SL8500 configuration without performing a LIBGEN, MERGEcds, and recycle of the HSC. However, this operation requires assistance from Oracle StorageTek Support.

The MODify command differs from the Vary command in the following ways:

The MODify command places a specified CAP or LSM online/offline globally to all hosts.
- A CAP that is modified offline cannot be used for eject/enter processing.
- An LSM that is modified offline must be operated in manual mode.
- A manual mode LSM is still available for diagnostic requests from a host.
The Vary command places a host station online/offline to an LMU.
- A host that has all of its LMU stations varied offline is disconnected from all LSMs attached to the LMU.
- An LSM can still be used to semi-automate cartridge handling for a disconnected host by issuing HSC commands from a connected host.

Syntax

Figure 3-16 shows MODify command syntax.

Figure 3-119 MODify command syntax

Surrounding text describes Figure 3-119 .

Parameters

As shown in Figure 3-119, the MODify command includes the following parameters:

CAP

specifies that a CAP is to be modified online/offline to all hosts.

cap-id

a specific CAP to be modified online/offline. The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

lsm-id

a standard CAP to be modified online/offline. The format of an lsm-id is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

ONline

specifies that the CAP is to be modified online to all hosts. When a CAP is modified online, the HSC attempts to restore the CAP mode (automatic or manual) that was in effect when the CAP was modified offline.

OFFline

specifies that the CAP is to be modified offline to all hosts. Modifying a CAP offline places it in an unavailable state, preventing it from being allocated. The CAP mode (automatic or manual) is retained in the control data set.

Be sure to specify the CAP parameter to modify a CAP offline. If the LSM is online, and you specify an lsmid to modify the CAP offline but do not specify the CAP parameter, the LSM will be modified offline.
Use this command only in an emergency. Make sure the CAP is not being used by another active process. Issuing the MODify command on an active CAP may cause the process using the CAP to receive errors.

LSM

optionally, indicates that one or more LSMs are to be modified online/offline to all hosts.

lsmid, lsmrange, or lsmlist

one or more LSMs to be modified online/offline to all hosts. Each lsmlist element may be either a single lsm-id or an lsm-range. The elements in a list must be separated by commas or blanks, and the entire list must be enclosed in parentheses.

The format of an lsm-id is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

ONline

specifies that the LSMs are to be modified online to all hosts. Modifying an LSM online places it in automatic mode. When an LSM is modified online, CAPs that were in auto mode before the LSM was modified offline are again placed in auto mode (unlocked state).

OFFline

specifies that the LSMs are to be modified offline to all hosts. Modifying an LSM offline places it in manual mode. CAPs in a manual mode LSM cannot be used, but the auto/manual state of each CAP is retained.

FORCE: specifies that the LSM(s) is to be modified offline immediately. FORCE is only used with the OFFline parameter to modify an LSM offline.

CONFIG

optionally, initiates the Near Continuous Operation (NCO) for hardware reconfiguration process for SL3000 and SL8500 libraries. This is a system wide change which propagates to all hosts connected to the CDS.

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information about Near Continuous Operation and dynamic hardware reconfiguration. Before you enter MODify CONFIG, perform a backup of the CDS.

no parms

Refer to Oracle's ELS publication Configuring HSC and VTCS for more information about Near Continuous Operation and dynamic hardware reconfiguration.
Before you enter MODify CONFIG, perform a backup of the CDS.

RESET

resets internal flags for any host that may be failing as a hardware configuration is being performed. The RESET also terminates any active dynamic hardware reconfiguration in the HSC complex during the hardware and software comparison phase. When the failing host comes back up, the new hardware configuration is automatically recognized and implemented.

A reset is intended only to reset a failing host and does not initiate the actual dynamic hardware reconfiguration operation. The MODify CONFIG command, without the RESET parameter, must be run separately to invoke dynamic hardware reconfiguration.

ADD

initiates an NCO configuration change to add one or more ACSs to the HSC configuration. The ACS added takes on the library characteristics of the library type specified by the ACSType parameter. The number of ACSs that can be added is limited by the number specified on the SLILIBRY FUTRACS parameter.

ACSType

specifies the library type to use for the configuration change. Options are SL3000 or SL8500.

Additionally, you can specify N (separated by a comma) to indicate the number of ACSs to add, from 1 to 9. If this keyword is not specified, 1 is the default.

DELete ACSid(acs-id)

initiates an NCO configuration change to delete the disconnected ACS specified in the ACSid(acs-id) parameter.

After the ACSid is deleted, the ACS cannot be re-added if the ACS was defined by a SLIACS statement. If the ACS was added by a prior MODify CONFIG ADD command, the ACS can be re-added.

If the ACSid is the not highest numbered ACS, the ACS is placed in "unallocated" status.
If the ACSid is the highest numbered ACS, the ACS is entirely deleted and can be re-added as a different ACSType.
If the ACSid is not the highest numbered ACS, the ACS becomes a place holder with a status of unallocated and can be re-added only as the same ACSType.

UPDate ACSid(acs-id)

initiates an NCO configuration change to update the ACS configuration specified in the ACSid(acs-id) parameter. This is a system wide change, and other hosts connected to the CDS are notified of the change.

The ADD and DELete parameters are only valid if the FUTRACS parameter was specified in the SLILIBRY macro during the LIBGEN process.

NOCell: Used in conjunction with ACS acs-id to bypass cell discovery within the ACS. This option is used only for drive and/or CAP changes and will reduce the reconfiguration time.
DRVinfo: Used in conjunction with ACS acs-id to update drive information (for example, serial number, worldwide name) for all drives of an ACS. This option is used only when replacing defective drives with drives of the same type.

Note:
When this command option is invoked, it executes immediately and does not disrupt library activity.

Mount

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The Mount command mounts a scratch or specific volume on a transport, or mounts a VTV on a VTD and optionally assigns a Management Class to that VTV.

Do not use this command to manage a mount that appears to have been missed by a batch job. Instead, use the SMC RESYNCHronize command to automate pending mounts. See "RESYNChronize" for more information.

Note:

The HSC Mount command does not support VTDs that are not defined in the VTCS CONFIG. The SMC Mount command must be used in place of the HSC Mount command for any VTDs that are not specified in the VTCS CONFIG.

Syntax

Figure 3-120 shows Mount command syntax.

Figure 3-120 Mount command syntax

Surrounding text describes Figure 3-120 .

Parameters

As shown in Figure 3-118, the Mount command includes the following parameters:

To Mount a Specific Volume on a Transport

volser

specifies the volume to be mounted.

devaddr

specifies the device address of the transport on which to mount the volume.

host-id

optionally, indicates that the volume is to be mounted on the device address defined to the specified host (the SMF system identifier for both JES2 and JES3).

Note:

The host-id specified is only used for device address resolution. The host-id for subpool validation is obtained from the command origin.

Readonly

indicates that the volume is to be mounted for readonly access.

If you do not supply a hostid and do specify Readonly, a comma must be entered immediately before Readonly to indicate the missing operand. For example:

MOUNT 123456 0B0,,READONLY

ForceRT

optionally, enables a volume to be mounted on a device with a different recording technique. The media type for the volume must be compatible with the device. Caution should be used because it is possible to mount a volume written at a high density on a drive that is not capable of reading the high density.

To Mount a Scratch Volume on a Transport

SCRTCH

specifies a scratch volume is to be mounted.

PRIVAT

specifies a scratch volume is to be mounted.

devaddr

specifies the device address of the transport on which to mount the volume.

host-id

optionally, indicates that the volume is to be mounted on the device address defined to the specified host (the SMF system identifier for both JES2 and JES3).

Note:

The host-id specified is only used for device address resolution, The host-id for subpool validation is obtained from the command origin.

SUBpool(subpool-name)

optionally, indicates the scratch volume is to be taken from a scratch subpool. If this parameter is not specified, then the behavior is dependent upon how scratch pools were defined:

If VOLPARM specified, then the volume will be selected from the DEFAULTPOOL which contains all scractch tapes in the ACS that were specified in VOLPARM but were not assigned to a named subpool.
If VOLPARM not specified (that is, VOLATTR, or UX03 scratch pool definitions), then the volume will be selected from subpool-0 which contains all scratch tapes in the ACS including both non-subpool and subpool volumes.

MEDia(media-type)

optionally, specifies the type of media for the scratch volume. The specified media must be compatible with the requested devaddr.

media-type indicates the media type.

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

Note:

If MEDia is not specified, the next scratch cartridge is selected without regard to media type.

To Mount a VTV on a VTD and Optionally, Assign a Management Class

volser

specifies a specific VTV volser. volser indicates the volser of a specific VTV.

SCRTCH

specifies the scratch VTV attribute (SCRTCH).

devaddr

specifies the MVS device address of the VTD to use to mount the VTV.

MGMTclas(mgmt-class-name)

optionally, specifies a Management Class you defined on the MGMTclas control statement.

mgmt-class-name indicates the Management Class name.

MOVe

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The MOVe command moves volumes to specified locations within the same LSM or to any other LSM within an ACS.

Note:

Movement of volumes to all LSMs is done on a first-come first-served basis. As volumes are moved, should an LSM become fully populated before the move request is satisfied for that LSM, the move request continues with the movement of volumes designated for the next LSM specified in the request. An LSM is fully populated when all available cells contain tape cartridges. This process continues until the entire move request is completed or all destination LSMs are full.
Moves are performed one at a time to allow for other LSM activity.

Syntax

Figure 3-18 shows MOVe command syntax.

Figure 3-121 MOVe command syntax

Surrounding text describes Figure 3-121 .

Parameters

As shown in Figure 3-121, the MOVe command includes the following parameters:

Flsm(lsm-id)

specifies the &rsquor;&rsquor;From'' LSMid in the format AA:LL that the cartridges are to be moved from. If you specify the Flsm parameter, you may not specify the Volume parameter.

lsmid indicates the LSM identifier name. An LSMid (lsm-id) is made up of the ACSid (decimal 00-99) and the LSM number (decimal 00-99) separated by a colon (:).

Panel(panel-list)

specifies a panel number to be moved from. This parameter has a corequisite of the Flsm parameter and is required.

An entire panel can be emptied if the Row and Column parameters are not specified.

panellist indicates a one or two digit panel number. Ranges are not valid. This parameter cannot contain a list if a list is specified for the Row or Column parameter.

Panels specified by panellist are excluded as destination panels if cartridges are being moved within the same LSM.

A panellist element is a one or two digit decimal number, specific to the LSM type. See "Panels" for a list of valid values.

Row(row-list)

specifies a list of rows to be moved from. This parameter has a corequisite of the Panel parameter.

rowlist indicates a one or two digit row number or list of row numbers. The maximum list allowed is four rows. However, this parameter cannot contain a list if a list was specified for the Column parameter. Ranges are not valid.

A rowlist element is a one or two digit decimal number, specific to the LSM type. See "Rows" for a list of valid values.

Column(column-list)

specifies a list of columns to be moved from. This parameter has a corequisite of the Row parameter and is optional. If this parameter is not specified, all columns will be moved for the rows specified.

columnlist indicates a one or two digit column number or list of column numbers. This parameter cannot contain a list if a list was specified for the Row parameter. Ranges are not valid.

A columnlist element is a one or two digit decimal number, specific to the LSM type. See "Columns" for a list of valid values.

Volume(vol-list)

optionally, specifies volumes to be moved.

vollist indicates a list of volumes (a maximum of 300 can be specified) or a range of volumes. If you specify the Volume parameter, you may not specify the Flsm parameter.

TLsm(lsm-list)

specifies the target LSM(s). This is a required parameter. The LSMs are specified as AA:LL, where AA indicates the ACSid and LL indicates the LSMid. The ACSid:

must be identical to the Flsm parameter &rsquor;&rsquor;aa'' (ACSid), or
must be the same ACS in which the volume resides if the Volume parameter is specified.

lsmlist indicates a list of LSMs (a maximum of 24 can be specified). Ranges are invalid. An LSMid (lsm-id) is made up of the ACSid (decimal 00-99) and the LSM number (decimal 00-99) separated by a colon (:).

TPanel(panel)

optionally, specifies the panel in the TLsm to move the cartridge(s) to.

panel indicates a one or two digit panel number. This parameter cannot contain a list or range. See "Panels" for a list of valid values.

MVCDRain

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The MVCDRain command recalls all current and scratched VTVs from an MVC and, optionally, ”virtually” ejects the MVC, making it unavailable for VSM use without physically ejecting it from the library. You can use this command to override the CONFIG RECLAIM CONMVC setting.

Syntax

Figure 3-122 shows MVCDRain command syntax.

Figure 3-122 MVCDRain command syntax

Surrounding text describes Figure 3-122 .

Parameters

As shown in Figure 3-122, the MVCDRain command includes the following parameters:

MVCid(volser, vol-range, or vol-list)

drain one or more MVCs by volser.

volser, vol-range, or vol-list indicates the volsers of one or more MVCs up to a maximum of 50.

Eject

optionally, specifies that VTCS ”virtually” ejects the MVC (the MVC will not be used for output).

For virtual MVCs (VMVCs):

MVCDRAIN with the EJECT parameter physically deletes the VTVs.

The current CDS backup can no longer be used as a DR baseline for VMVC content if you use the DRCHKPT utility or the CONFIG RECLAIM PROTECT parameter to protect CDS backup content for VMVCs, and then issue the MVCDRAIN EJECT command.
MVCDRAIN without the EJECT parameter does not delete the VTVs, but updates the CDS record to show no VTVs on the VMVC.

CONMVC(nn)

optionally, specifies the maximum number of MVCs that VTCS concurrently processes for both drain and reclaim.

nn indicates the number of MVCs. Valid values are 1 to 99. If not specified, the default is the CONMVC value specified on the CONFIG RECLAIM statement.

MVCPOOL(poolname)

drain the MVCs in the specified Named MVC Pool.

pool-name indicates the name of an MVC Pool that you defined on the MVCPool control statement. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for more information.

STORCLAS(storclas-name)

drain the MVCs in the specified Storage Class.

stor-class-name indicates the name of a Storage Class that you defined on the STORclas control statement; for more information, see "STORclas Control Statement".

RECALWER

optionally, specifies whether VTCS recalls VTVs with read data checks.

NO: Do not recall VTVs with read data checks. This is the default.
YES: Recall VTVs with read data checks.

NOWAIT

optionally, specifies that the utility does not wait for the operation to complete and returns after the request is submitted.

WARRANTY

optionally, selects MVCs with expired warranties (denoted by a W in the Status T column on an MVC Report).

RETIRED

optionally, selects MVCs that are retired (denoted by a T in the Status T column on an MVC Report).

ERROR

optionally, selects MVCs that are in error (denoted by a B in the Status B column on an MVC Report).

DATACHK

optionally, selects MVCs that have a data check (denoted by a D in the Status D column on an MVC Report).

MVCMAINT

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS required if RENVTSS is specified
Can run in batch-only mode when there are no hosts active (on any LPAR) using the CDS that is to be updated

Description

The MVCMAINT command specifies MVC attributes.

Syntax

Figure 3-123 shows MVCMAINT command syntax.

Figure 3-123 MVCMAINT command syntax

Surrounding text describes Figure 3-123 .

Parameters

As shown in Figure 3-123, the MVCMAINT command includes the following parameters:

MANIFEST(ddname)

specifies the input ddname of the manifest file. Note that you can specify a merged manifest file or multiple manifest files.

ddname indicates the DD name of the manifest file. The default is MANIFEST.

When specified, VTCS reads the MANIFEST file to discover which MVCs are to be updated (all MVCs in the manifest file). VTCS then updates the MVCs in the CDS with the actions specified by the remaining parameters (LOST, READONLY, etc)

MVC(volser, vol-range, or vol-list)

optionally, specifies the MVCs whose read/write attribute is changed.

volser, vol-range, or vol-list indicates the volsers of one or more MVCs. You can specify a maximum of 50 MVCs.

READONLY

optionally, sets the read/write status of the MVC.

ON: MVC is readonly.
OFF: MVCs is writable.

LOST

optionally, sets the ”lost” status of the MVC.

ON: MVC is lost.
OFF: MVCs is not lost.

ERROR

optionally, sets the error status of the MVC.

ON: MVC is in error.
OFF: MVCs is not in error.

EJECT

optionally, sets the ”logical eject” status of the MVC.

ON: MVC is ”logically ejected”.
OFF: MVC is not ”logically ejected”.

RETIRED

optionally, sets the ”retired” status of the MVC.

ON: MVC is retired.
OFF: MVC is not retired but is still in ”expired warranty” state (still selectable for output).

WARRANTY

optionally, sets the ”expired warranty” status of the MVC.

ON: MVC's warranty has expired.
OFF: MVC's warranty has not expired.

Note:

WARRANTY and RETIRED are mutually exclusive.

INVLDMIR

optionally, sets the invalid MIR status of the MVC.

ON: MIR is invalid.
OFF: MIR is not invalid.

REPLACED

optionally, updates various MVC fields in the MVC record after an MVC is physically replaced.

NONE

The MVC record is not updated.

MEDIA

The following MVC fields are updated:

MVC media type is cleared
Count of times mounted is set to zero
Warranty Expired Flag is turned off
Invalid MIR Flag is turned off
Retired Flag is turned off
Broke/Error Flag is turned off
Lost Flag is turned off
Data Check Flag is turned off
VTSS Last Written By is cleared
Date/Time MVC was last written to is cleared
Storage Class is cleared
Date/Time of Last Drain/Reclaim is cleared
Date/Time of Migrate from Empty State is cleared
Date/Time the MVC was last mounted is cleared

Note:

This parameter requires the MVC to be empty (contain zero) and unmounted. REPLACED is mutually exclusive with the LOST, ERROR, EJECT, RETIRED, WARRANTY, and INVLDMIR parameters.

RENVTSS(vtss-name)

optionally, sets the name of the owning VTSS to vtss-name.

vtss-name indicates the new VTSS name. This must be the name of an existing VTSS in your configuration.

Note:

To use RENVTSS, the host on which MVCMAINT is run must have access to the owning VTSS.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the MVCMAINT JCL:

manifest file DD: DD statement for the manifest file.

Note:

MVCMAINT JCL may specify the CDS to be updated if the CDS is in use by HSC/VTCS on the LPAR where MVCMAINT is run. If specified, the CDS data sets specified in MVCMAINT JCL must match the CDS data sets used by HSC/VTCS.
MVCMAINT JCL must specify the CDS to be updated if MVCMAINT is being executed in batch-only mode, i.e. when there are no hosts active (on any LPAR) using the CDS.

Return Codes

The MVCMAINT command includes the following return codes:

0 indicates that all requested updates for the MVC completed successfully.
4 indicates that one requested update for the MVC failed and at lest one other requested update completed successfully.
8 indicates that all requested updates for the MVC failed.

Note:

The final return code for the MVCMAINT job is the largest return code generated by any single MVC updated. For example, if 5 MVCs generate a return code 0 and one MVC generates a return code 8, the final return code is 8.

MVCMAINT Report

The following is an example of an MVCMAINT report produced by the following command:

An exception report of the reason for all uncompleted updates.
An MVC summary report.

MVCPLRPT

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The MVCPLRPT command reports the status of a named MVC Pool or MVC Storage Class.

Syntax

Figure 3-124 shows MVCPLRPT command syntax.

Figure 3-124 MVCPLRPT command syntax

Surrounding text describes Figure 3-124 .

Parameters

As shown in Figure 3-124, the MVCPLRPT command includes the following parameters:

MVCPOOL(poolname)

optionally, report on MVCs in the specified Named MVC Pool.

poolname indicates the name of an MVC Pool that you defined on the MVCPool control statement. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for more information.

To report on all Named MVC Pools (including DEFAULTPOOL), specify ALL or omit the MVCPOOL parameter.

STORCLAS(storclas-name)

optionally, report on MVCs in the specified Storage Class.

stor-clas-name indicates the name of a Storage Class that you defined on the STORclas control statement. See Appendix A, "MEDia, RECtech, and MODel Values" for more information. You can also specify Storage Classes which used to exist to which media is still assigned.

To report on all Storage Classes, specify ALL or omit the STORCLAS parameter value.

The STORCLAS parameter enables you to filter the MVCs reported from the MVCPOOL, i.e. only those MVCs with a matching Storage Class are reported. If the STORCLAS parameter is specified then the summary counts section will contain Storage Class subtotals, either for every Storage Class encountered if the parameter value ALL or no value is specified, or for those media types where there are MVCs matching the specified value.

DETail

Report MVC detail lines (the default).

SUMmary

Report summary counts only.

Fields

The following list describes the Named MVC Pool report fields. The Summary fields are either for a Storage Class or a Named MVC Pool, depending on which was specified on the report JCL. If a Storage Class specifies a Named MVC Pool, the report gives information for that subpool.

MVC Volser

the MVC volser.

Number of VTVS

the number of current VTVs on the MVC. If the MVC has been used for VTV export, this field reports EXPVTV.

Available (GB)

the available space, specified in Gb, on the MVC.

Used (GB)

the used space, specified in Gb, occupied by current VTVs on the MVC.

Fragmented (GB)

the fragmented space, specified in Gb, occupied by non-current VTVs on the MVC. This space is not usable until it is reclaimed or the MVC is drained.

Unavailable (GB)

the unavailable space, specified in Gb, on the MVC. MVC with the following states are unavailable:

FULL
BROKE
RETIRED
DATACHECK
READONLY
Warranty Expired

Size (GB)

the media size of the MVC specified in Gb. This will only be determined after VTCS has used an MVC. "UNKNOWN" appears in this field until VTCS migrates a VTV to the MVC.

MVCs in a VLE have a nominal capacity of 250Gb. When VTVs are migrated with deduplication to a vMVC, the VTVs are divided into VTV unique data and data shared with other VTVs, which can reside on different vMVCs. As a result:

The sum of the VTVs can exceed the 250Gb vMVC media size, because the VTVs reference shared data that exists on other vMVCs.

Conversely, the sum of the VTV sizes on a full vMVC can be less than the 250Gb media size because the vMVC contains shared data for VTVs that reside on other vMVCs. For example, in an extreme case, a vMVC can have zero VTV copies but have zero available or fragmented space (the vMVC is full of shared VTV data).

STATUS

one or more of the following statuses:

I

The MVC has been initialized. A partitioned MVC is indicated by a P.

B

The MVC has an error that should be investigated. The error may not make the MVC unusable, but VTCS will not select the MVC for migration for 12 hours after it is marked B. After the 12 hour period, the MVC will be least preferred for subsequent migrations, and recalls from the MVC may cause VTCS to drain it. This error condition may be accompanied by messages SLS6686, SLS6687, SLS6688, SLS6690, and/or SLS6693.

Any of the following conditions can cause this MVC error:

MVC corrupted by another job (other than VTCS/VTSS)
attempt to use a read-only MVC for migration
DDR swap failure
RTD failure

L

The MVC was not mounted in response to the last mount request. The MVC can still be used for migration, but will not select the MVC for migration for 12 hours after it is marked L. After the 12 hour period, the MVC will be least preferred. This condition will clear itself the next time that the MVC is mounted.

D

A data check was reported for this MVC. VSM will not use this MVC again for migration.

R

the MVC has been marked read-only.

U

one of the following usage statuses:

U: the MVC is available for output (migration, reclamation, export, or consolidation).
-: the MVC is not available for output (migration, reclamation, export, or consolidation).
A: The MVC is either being audited or the audit failed. If the audit failed, VTCS will not use the MVC for migration. To clear this condition, rerun the AUDIT against this MVC.
C: The MVC is a consolidation MVC.
E: The MVC is an export MVC.
F: There is no space available on the MVC.
J: Either you issued an MVCDRain EJect for the MVC or the MVC was ejected for update by a RACROUTE call. The MVC will not be used again for migration or recall. To clear this condition, use MVCDRain against MVC without the EJect option.
N: Either the MVC is being drained because of an automatic drain or demand reclaim or an explicit MVCDRain command, or the previous DRAIN request failed, in which case VTCS will not use the MVC for migration. To clear this condition, enter MVCDRain against MVC without the EJect option.
X: The MVC has reached the maximum VTVs per MVC.

T

One of the following statuses:

T: The MVC is retired.
W: The MVC's warranty has expired.

M

The MVC has an invalid MIR.

Not in summary

MVC with the following states are not included in the MVCPLRPT summary:

EJECTED
READONLY
DATACHECK
Logically Deleted

Summary for Storage Class or Named MVC Pool

This section shows number of MVCs and total storage (Gb) by ACS and media type:

Total MVC count: Total number of MVCs.
Free MVC count: MVCs that have 100% usable space and do not contain any migrated VTVs. The storage shown is the total free space based on media type capacity.
Available (GB): Available space, specified in Gb, on the MVC.
Used (GB): Used space, specified in Gb, occupied by current VTVs on the MVC.
Fragmented (GB): Fragmented space, specified in Gb, occupied by non-current VTVs on the MVC. This space is not usable until it is reclaimed or the MVC is drained.
Unavailable (GB): Unavailable space, specified in Gb, on the MVC.

Summary of MVCs by usage

This section shows number of MVCs by the task that last used the MVC:

MVCRPt

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required

Description

The MVCRPt command reports the status of your VSM system's MVCs.

Syntax

Figure 3-125 shows MVCRPt command syntax.

Figure 3-125 MVCRPt command syntax

Surrounding text describes Figure 3-125 .

Parameters

As shown in Figure 3-118, the MVCRPt command includes the following parameters:

MVCid(volser, vol-range, or vol-list)

optionally, specifies the MVCs for the report. If you do not specify the MVCs, the report includes all MVCs in your VSM system.

volser, vol-range, or vol-list indicates the volsers of one or more MVCs.

STORclas(storclas-name)

optionally, specifies a storage class with the MVCs to be reported.

stor-clas-name indicates a 1-8 character storage class name.

Note:

STORclas is mutually exclusive with MVCid, ALL, and MANIFEST.

ALL

optionally, generate a report for all MVCs according to the selection criteria, even those that would otherwise be omitted.

MANIFEST(ddname)

optionally, specifies the input DD name of the manifest file used to generate the report.

ddname indicates the DD name of the manifest file. Note that you can specify a merged manifest file or multiple manifest files.

DETail

optionally, produce a detailed MVC report. See Example 3-54 for an example. If you do not specify this option, the default is to produce a summary MVC report. See Example 3-53 for an example.

CHECK

optionally, MVCRPt does limited MVC integrity checking, during which the CDS is reserved. Use only if directed by Oracle StorageTek Software Support.

WRITABLE

optionally, MVCRPt ignores read only MVCs on MVC detailed reports and when you specify the CHECK parameter.

MVC Reports

The following sections describe the MVC summary and detailed reports produced by the MVCRPt command.

MVC Summary Report

The following figure shows an example of an MVC summary report:

Fields

The MVCRPt MVC summary report includes the following fields:

MVC Volser

the MVC volser.

Number of VTVS

the number of current VTVs on the MVC. If the MVC has been used for VTV export, this field reports EXPVTV.

%Used

the percentage of the MVC used by current VTVs.

%Avail

the percentage of the MVC that is physically available for use.

%Frag

the percentage of the MVC that contains non-current VTVs. This space is not usable until it is reclaimed or the MVC is drained.

Size (GB)

the size of the MVC (GB). This will only be determined after VTCS has used an MVC. N/A appears in this field until VTCS migrates a VTV to the MVC.

Note that MVCs in a VLE have a nominal capacity of 250 GB. When VTVs are migrated with deduplication to a VMVC, the VTVs are divided into VTV unique data and data shared with other VTVs, which can reside on different VMVCs. As a result:

The sum of the VTVs can exceed the 250 GB VMVC media size, because the VTVs reference shared data that exists on other VMVCs.

Conversely, the sum of the VTV sizes on a full VMVC can be less than the 250 GB media size because the VMVC contains shared data for VTVs that reside on other MVCs. For example, in an extreme case, a VMVC can have zero VTV copies but have zero available or fragmented space (the MVC is full of shared VTV data).

Times Mounted

the number of times that the MVC has been mounted for writing or reading since it was added to the MVC inventory.

STATUS

one or more of the following statuses:

I

The MVC has been initialized. MVCs written in partitioned format are indicated by the letter 'P' under this column.

B

This is a generic error that indicates the MVC, drive, or combination of the two has a problem. VTCS attempts to de-preference MVCs with this state. To clear this state:

If the MVC caused the problem, use a DRAIN(EJECT) command to remove the MVC from service.

If the RTD caused the problem, use the MVCMAINT utility to reset the MVC state.

Note also that one or more of the following messages is issued for BROKEN status: SLS6686, SLS6687, SLS6688, SLS6690. For detailed recovery procedures for these messages, refer to Oracle's ELS publication ELS Messages and Codes.

L

VTCS attempted to mount an MVC and the mount did not complete within a 15-minute time-out period. VTCS is attempting to recover from a situation that may be caused by hardware problems, HSC problems, or by the MVC being removed from the ACS. VTCS attempts to de-preference MVCs with this state.

If VTCS does perform a subsequent successful mount of an MVC with LOST(ON) state, VTCS sets the state to LOST(OFF).

Determine the cause of the error and fix it. You can also use the VTCS MVCMAINT utility to set LOST(OFF) for the following events:

LOST(ON) was set due to LSM failures or drive errors that have been resolved

LOST(ON) was set because the MVC was outside the ACS and has been reentered.

D

A data check condition has been reported against this MVC. VTCS attempts to de-preference MVCs with this state. To clear this state:

If all VTVs on the MVC are duplexed, use MVCDRain on the MVC without the Eject option. This recovers all VTVs and removes the MVC from service.

If all VTVs on the MVC are not duplexed, VTCS AUDIT the MVC. The audit will probably fail. After the audit, do an MVCDRAIN (no eject). This recalls the VTVs before the data-check area in ascending block-id order and the VTVs after the data-check area in a descending block-id order. Processing the VTVs in this sequence ensures that VTCS recovers as many VTVs as possible from the media. You then need to recreate the data for any VTVs still on the MVC.

R

The MVC has been marked read-only because of one of the following conditions:

The MVC being the target of an export or consolidation process. The read-only state protects the MVC from further updates.

The MVC media is set to file protect. Correct the error and use the MVCMAINT utility to set READONLY(OFF).

The MVC does not have the appropriate SAF rules set to enable VTCS to update the MVC. Correct the error and use the MVCMAINT utility to set READONLY(OFF). Refer to Oracle's ELS publication Installing ELS for information about defining a security subsystem user ID for HSC, SMC, and VTCS.

U

One of the following usage statuses:

U: The MVC is available for output (migration, reclamation, export, or consolidation).
-: The MVC is not available for output (migration, reclamation, export, or consolidation).
A: The MVC is either being audited or the audit failed. If the audit failed, VTCS will not use the MVC for migration. To clear this condition, rerun the AUDIT against this MVC.
C: The MVC is a consolidation MVC.
E: The MVC is an export MVC.
F: There is no space available on the MVC.
J: Either you issued MVCDRain EJect for the MVC or the MVC was ejected for update by a RACROUTE call. The MVC will not be used again for migration or recall. To clear this condition, use MVCDRain against MVC without the EJect option.
N: Either the MVC is being drained because of an automatic drain or demand reclaim, or an explicit MVCDRain command, or the previous DRAIN request failed, in which case VTCS will not use the MVC for migration. To clear this condition, enter MVCDRain against MVC without the EJect option.
X: The MVC has reached the maximum VTVs per MVC.

T

One of the following statuses:

T: The MVC is retired. VTCS will recall from, but not migrate to, the MVC. Replace the MVC as soon as possible.
W: The MVC's warranty has expired. VTCS continues to use the MVC. You should start making plans to replace the MVC when it reaches Retired state.

M

VTCS detects the invalid MIR condition at either mount time or dismount time. If detected at mount time and the operation can be completed with another MVC, VTCS dismounts the first MVC and selects the alternate MVC. Note that VTCS has only a limited ability to switch to an alternate MVC. That is, it is mainly used for migrate and virtual mount.

For MVCs with invalid MIRs, determine the cause of the error, which may be caused by media or drive problems, and fix the error.

To recover an MVC with an invalid MIR, you simply need to read the MVC to the end of the tape, which can be done via a VTCS audit. If the media is the problem, run an MVCDRAIN EJECT to recall the VTVs and cause the MVC to be removed from the MVC pool.

Last Mounted

the date and time that the MVC was last mounted and the VTSS where the MVC was last used.

Location/ACS ID

the ACS containing the MVC, or the VLE containing remote MVC volumes or VMVCs in VLEs.

**MANY** indicates that an MVC with a specific volser has been discovered in more than one location. MVCs in this state are marked unusable.

Owner/Consolidate Time

If the MVC is empty, this field is null. If the MVC is a consolidation MVC, this field displays the time of the consolidation. If the MVC is a migration MVC and contains current VTVs, this field displays the MVC's Storage Class. If no Storage Class was explicitly assigned via the MGMTclas statement, the default Storage Class is the name of the last VTSS that wrote to the MVC for reclamation or migration.

If VTCS receives a request to migrate a VTV that is assigned to an invalid Management Class, VTCS will dynamically create the !ERROR Storage Class and migrate the VTVs defined by the invalid Management Class to the !ERROR Storage Class. Use this Storage Class to identify and correct invalid Management Classes, drain the affected MVCs, and resubmit the request.

Initialized MVCs processed

the total number of initialized MVCs. Also includes a breakdown of the number of MVCs that are standard format or partitioned.

Non-Initialized MVCs processed

the number of non-initialized MVCs.

Non-library MVCs processed

the number of non-library MVCs processed.

MVC Detailed Report

The MVC detailed report provides all the fields from the MVC summary report and a separate section that lists additional fields. The following figure shows an example of these additional fields from an MVC detailed report.

Fields

The MVCRPt MVC detailed report includes the following additional fields:

VTV Volser

the volsers of the VTVs on the MVC.

Size (MB)

the uncompressed size of the VTV (MB).

Block ID

the partition id and logical block ID of the beginning of the VTV on the MVC. If there are VTVs spanning partitions, the spanned to partition is shown to the right of the blockid location.

Management Class

the VTV's Management Class.

Migration Date

for migrates done by a 6.0 system or above only, the approximate date that the VTV copy was migrated. This date is approximate because it is recorded in the CDS as the number of days since VTV creation, and time zone adjustments can cause the value to slip a day.

Block Count

the decimal number of blocks of data that the VTV occupies on the MVC.

Message

reports the results of MVC integrity checking. Any message not listed below should be reported to Oracle, as it may indicate a serious problem with the CDS except messages that can appear if the MVC is being audited or has failed an audit while the MVC report is being run. An MVC report returns a minimum return code of 4 if any MVCs in audit state are encountered; the audit state also prevents some other errors from being reported.

nnnn empty space to previous

Explanation: Informational message, indicating that there are nnnn (decimal) blocks of free space before this VTV on the MVC.

Migrated size was not as expected

Explanation: If output for VTV v on MVC m, it indicates that the (compressed) size of VTV v migrated to MVC m was different to the (compressed) size of VTV v recorded in the CDS.

This is normal if VTV v had previously been recalled with error. Otherwise this indicates a possible error which should be reported to Oracle StorageTek software support.

Used/Unused Partitions

Summary of used and unused partitions for the MVC.

OFFload

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The OFFload command offloads transaction records from active log file(s) used by the HSC Transaction Logging Service and saves them in a sequential data set so that space in the log files can be reused.

If logging is currently active, you must run the OFFload LOGFILE utility to change log file names.

Syntax

Figure 3-126 shows OFFload command syntax.

Figure 3-126 OFFload command syntax

Surrounding text describes Figure 3-126 .

Parameters

As shown in Figure 3-126, the OFFload command includes the following parameters:

LOGFILE

This keyword is required. Generally, OFFload LOGFILE is issued without parameters. The utility selects the input log data set from the active log data sets as recorded in the CDS.

LOGDSN(primary-log-file-dsn)

optionally, offloads the log file without using or updating the CDS. Use this parameter in any case where the CDS is restored, or is otherwise considered to be unreliable.

primary-log-file-dsn indicates the data set name for the primary log file.

For example:

OFFLOAD LOGFILE LOGDSN(hsc.log1)

RESTART

optionally, restarts the offload, selecting the input log file from among the group of log data sets that were active when the failed offload started. It also uses the block number range used by the failed offload.

Use this parameter to recover the records from the log data set(s) that become inactive when a failed offload causes a log data set switch.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the OFFload LOGFILE JCL:

SLSOFFLD

specifies the output data set

It is recommended that no DCB be specified for this data set. If a DCB is specified, the RECFM and LRECL are ignored.

OPTION TITLE Control Statement

The OPTION TITLE control statement specifies an identifying string for a definition data set. This identifying string can be any information that helps the user describe the contents of the definition data set. You can specify this statement in a definition data set along with the following:

LMUPDEF
MGMTDEF
TREQDEF (SMC)

You can also specify this control statement using the following legacy HSC commands, as described in the ELS Legacy Interfaces Reference:

MVCDEF
SCRPDEF
VOLDEF

The OPTION TITLE statement must be placed in a definition data set; it cannot be issued as an operator command. If more than one OPTion statement is specified in the definition data set, only the identifying string of the last OPTion statement encountered is retained.

Syntax

Figure 3-127 shows OPTION TITLE control statement syntax.

Figure 3-127 OPTION TITLE control statement syntax

Surrounding text describes Figure 3-127 .

Parameters

As shown in Figure 3-127, the OPTION TITLE control statement includes the following parameters:

identifying-string

indicates an identifying string for the definition data set. The maximum length of the identifying string is fifty characters. If the identifying string includes one or more spaces, or any characters other than alphabetic, numeric, or national (for example, $, @, #), it must be enclosed in quotes.

TRACE or TRACEF: optionally, used to control internal tracing of HSC table lookups. During problem resolution, Software Support may request that you specify one of these parameters.

OPTion

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The OPTion command sets or changes general HSC options.

Syntax

Figure 3-128 shows OPTion command syntax.

Figure 3-128 OPTion command syntax

Surrounding text describes Figure 3-128 .

Parameters

As shown in Figure 3-128, the OPTion command includes the following parameters:

Dialog

enables HSC messages to be written to the operator console and/or the system log. These messages indicate that the HSC is waiting for an active task to complete before the HSC terminates. The initial Dialog value is set by the EXEC statement during HSC startup.

Off: specifies that messages are not to be written. Off is the default value for the HSC if the Dialog parameter is not specified on the EXEC statement.
Both: specifies that messages are written to the system log and the operator console.
Console: specifies that messages are written to the operator console only.
Log: specifies that messages are written to the system log only.

DISCmsg

specifies whether or not the ACS acsid is disconnected message (SLS1664A) is displayed for the specified ACS.

This option is useful when an ACS has been added to the LIBGEN in advance to provide for future expansion. Entering DISCmsg enables the user to turn off the display for those ACSs that will not be connected until later.

SHow

Displays the ACS acsid is disconnected message (SLS1664A) for an ACS. This is the initial value.

SUppress

Suppresses the ACS acsid is disconnected message (SLS1664A) for an ACS.

ACS(acs-id)

optionally, specifies the ACS for which the command applies. If ACS is not specified, the DISCmsg setting entered (Show or Suppress) applies to all ACSs.

acsid indicates the decimal ACSid value (00-99). If ACS is not specified, all ACSs are affected.

DUPOFL

optionally, enables the duplicate VOLSER process to continue when the VOLSER being entered into the CAP shows in the CDS that it exists in an ACS that is disconnected, or in an LSM that is offline.

OFF: disables the duplicate VOLSER process. This is the default.
ON: enables the duplicate VOLSER process.

EJLimit(count)

indicates the maximum number of cartridges that can be specified on one EJect command.

count indicates the maximum number of cartridges. Allowable values are 1 through 9999. The HSC initial value is 300.

ENTdup

specifies whether the HSC prompts the operator when an enter operation finds a duplicate VOLSER in the control data set, but cannot locate the cartridge in the ACS.

When someone attempts to enter a cartridge with a VOLSER that duplicates an entry in the control data set, the HSC attempts to locate the original cartridge. The ENTdup option determines how the HSC responds when the cartridge is not in its home cell, is not selected, and is not errant.

Auto: instructs the HSC to delete the cartridge in the control data set and allow the enter to continue.
Manual: instructs the HSC to issue a console message when a duplicate VOLSER is entered. The message prompts the operator to decide whether the HSC should delete the cartridge in the control data set and allow the enter to continue, or eject the duplicate cartridge. Manual is the initial value for the HSC.

Output

specifies whether the output messages are displayed on the console in uppercase or mixed case.

Upper: specifies uppercase. Upper is the initial value for the HSC.
Mixed: specifies mixed case.

SEN

enables or disables the Significant Event Notification (SEN) facility. Refer to Oracle's ELS publication ELS Programming Reference for more information about the SEN.

ON: enables the SEN facility.
OFF: disables the SEN facility. In this mode, the SEN facility accepts registration requests. However, invocation of listener programs is not performed. This is the initial value for HSC.

Viewtime(count)

specifies the length of time in seconds the system is to hold an LSM camera in one location when the VIew command is issued. See "VIew" for more information.

count indicates the number of seconds. Allowable values for count are decimal in the range from 5 through 120. The initial value for the HSC is 10 seconds.

The VIew command enables the user to override the OPTion Viewtime setting for a single viewing operation.

An SMF record (subtype 8) is written when the VIew command is issued to document robot activity.

Warnmsg(minutes)

sets the number of minutes between scratch depletion messages.

minutes indicates the number of minutes. Allowable values for minutes are 1 through 65535. The initial value is 5 minutes.

HOSTID(host-id)

optionally, identifies the host associated with the OPTion command. This enables you to restrict certain startup options to a specific host.

If this parameter is not specified, the command options are applied to each host that accesses PARMLIB.

hostid indicates the host identifier (the SMF system identifier for both JES2 and JES3).

Note:

If the hostid does not match the host executing the command, a message is issued and the command is not processed.

PITCOPY

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The PITCOPY command uses a utility snapshot feature to produce a point-in-time copy of the CDS. PITCOPY ensures CDS backup integrity by performing a CDS RESERVE to ensure that any ongoing updates are serialized. The PITCOPY function backs up only the primary CDS. Refer to Oracle's ELS publication Managing HSC and VTCS for more information about how to use the PITCOPY utility.

Syntax

Figure 3-129 shows PITCOPY command syntax.

Figure 3-129 PITCOPY command syntax

Surrounding text describes Figure 3-129 .

Parameters

As shown in Figure 3-129, the PITCOPY command includes the following parameters:

METHOD

specifies the snapshot copy utility to use for the PIT copy.

ADRDSSU: DFSMSdss SnapShot/DFSMSdss FlashCopy (ADRDSSU)
SIBBATCH: StorageTek SVAA SnapShot (SIBBATCH) utility
FDRSNAP: specifies that messages are written to the operator console only.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the PITCOPY JCL:

SLSPARMP: specifies a parameter file containing control statements to back up the CDS data set defined as SLSCNTL. Note that this may not be the primary CDS data set at the time the backup is taken.
SLSPARMS: specifies a parameter file containing control statements to back up the CDS data set defined as SLSCNTL2.
SLSPARMB: specifies a parameter file containing control statements to back up the CDS data set defined as SLSSTBY.
SYSIN: specifies a file to be output by the PITCOPY function and used as input to the snapshot copy function. When the PITCOPY function determines the primary CDS, it copies the appropriate SLSPARMx file into SYSIN.

Note:

Other definition statements are required by the snapshot utility you are requesting.
If you use Oracle's StorageTek SVAA SnapShot function, it is recommended that you use the SOURCE option specifying the data set name, rather than the INDDNAME option specifying the DDNAME; or that you always include the DD statements for the CDS data sets. If the dynamic CDS allocation feature is used, the primary CDS is automatically allocated to SLSCNTL. Therefore, a control statement in SLSPARMS, for example, to back up the SLSCNTL2 DD, would result in backing up a CDS copy that is not the primary.

RECall

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The RECall command performs demand recalls of VTVs to a VTSS.

Syntax

Figure 3-130 shows RECall command syntax.

Figure 3-130 RECall command syntax

Surrounding text describes Figure 3-130 .

Parameters

As shown in Figure 3-130, the RECall command includes the following parameters:

VTVid(volser, vol-range, or vol-list)

specifies the VTVs to recall.

volser, vol-range, or vol-list indicates the volsers of one or more VTVs. You can also specify one or more ranges.

DSN(name)

specifies data sets used to select VTVs to recall.

name indicates the data set name. Table 3-12 describes the valid wildcards for data set names.

MGMTCLAS(mgmt-class-name or mgmt-class-list)

specifies one or more Management Classes that determine one or more VTVs to recall.

mgmt-class-name or mgmt-class-list indicates the names of one or more Management Classes that you defined on the MGMTclas control statement. For more information, see "MGMTclas Control Statement".

MGMTCLAS, VTVid, and DSN are mutually exclusive.

RECALWER

optionally, specifies whether VTCS recalls VTVs with read data checks.

NO: Do not recall VTVs with read data checks. This is the default.
YES: Recall VTVs with read data checks.

VTSS(name)

specifies where the VTVs are recalled as follows:

If you do not specify a VTSS (the default), VTCS attempts to recall the VTVs to the VTSS of creation if it is accessible. Otherwise VTCS recalls the VTVs to the VTSS with the lowest DBU.
If you specify a single VTSS, VTCS attempts to recall the VTVs to the specified VTSS if it is accessible. Otherwise, VTCS recalls the VTVs to the VTSS with the lowest DBU.
If you specify a list of VTSSs, VTCS attempts to recall the VTVs to the VTSS of creation if it is on the list and accessible, otherwise VTCS recalls the VTVs to the VTSS with the lowest DBU on the list.

name indicates the names of one or more VTSSs.

NOWAIT

optionally, specifies that the utility does not wait for the operation to complete and returns after the request is submitted.

RECLaim

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The RECLaim command performs demand MVC space reclamation. This command can also override the CONFIG RECLaim settings for the THRESHLD, INPTHRSH, MAXMVC, and CONMVC parameters.

Syntax

Figure 3-131 shows RECLaim command syntax.

Figure 3-131 RECLaim command syntax

Surrounding text describes Figure 3-131 .

Parameters

As shown in Figure 3-131, the RECLaim command includes the following parameters:

MVCPOOL(poolname)

reclaim the MVCs in the specified Named MVC Pool.

poolname indicates the name of a Named MVC Pool that you defined on the MVCPool control statement. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for more information.

STORCLAS(stor-clas-name)

reclaim the MVCs in the specified Storage Class.

stor-clas-name indicates the name of a Storage Class that you defined on the STORclas control statement; for more information, see "STORclas Control Statement".

ACSid(acs-id)

reclaim the eligible MVCs in the specified ACS.

acs-id indicates a two digit decimal ACS identifier from 00-99.

MVC(volser, vol-range, or vol-list)

reclaim the specified MVC(s).

volser, vol-range, or vol-list indicates the volsers of one or more MVCs. You can also specify individual MVCs and ranges in a list. For example:

(MVC000-MVC005,MVC010,MVC015)

MAXMVC(nn)

optionally, specifies the maximum number of MVCs that will be processed by a single space reclamation task.

nn indicates the maximum number of MVCs. Valid values are 1 to 98. There is no default; if not specified, the CONFIG RECLAIM value (or default) is used.

For automatic space reclamation to start, the number of eligible MVCs (determined by the THRESH parameter) must also exceed the MAXMVC value.

THRESH(nn)

optionally, specifies the percentage of fragmented space that makes an MVC eligible for demand or automatic reclamation.

nn indicates the percentage of fragmented space. Valid values are 4 to 98. If not specified, the CONFIG RECLAIM value (or default) is used.

INPTHRSH(nn)

optionally, specifies the percentage of fragmented space that makes an MVC in partitioned format eligible for dynamic reclaim processing. This value overrides the global INPTHRSH value specified in the CONFIg RECLAIM statement. If this parameter is not specified, the current active global INPTHRSH value is used.

nn indicates a percentage between 3 and 97. This value must be less than the THRESHLD value.

Note:

If INPTHRSH is specified, THRESHLD must also be specified. Both INPTHRSH and THRESHLD play roles when space reclamation processes MVCs in partitioned format. Refer to Oracle's ELS publication Configuring HSC and VTCS for more information.

MOVEDATA

optionally, specifies the extent of VTV data movement to occur as a result of an MVC being reclaimed by the RECLaim command.

Standard

Move all VTV copies from the MVC being reclaimed to the currently applicable Storage Classes as specified in the MGMTclas or STORclas definitions.

A new STORclas definition may have been explicitly implemented by MGMTDEF changes, or it could be as a result of an ARCHIVE policy specifying a new STORclas taking effect.

This is the default.

Minimum

For an ALP MVC being reclaimed INPLACE, if the fragmentation percentage space in a partition exceeds the THRESH value specified on the RECLaim command, move all VTV copies from the MVC being reclaimed to the currently applicable Storage Classes as specified in the MGMTclas or STORclas definitions. This option supplies the Defrag function for an ALP MVC.

If a VTV spans partitions, it may have a segment in a low-use partition. For a partition to be eligible for defrag, the total size of all VTVs that reside partially or completely within the partition is used to calculate the used space associated with the partition.

For defrag to occur, the total associated used space must be less than 100 minus the THRESH value percentage of the partition size. This prevents the RECLaim from potentially recalling a large amount of data residing in multiple partitions to free up a small amount of space in a single partition.

Do not move VTV copies from a VLE VMVC to a new Storage Class.

None

Do not move VTV copies from any MVC. This turns off all data movement.

Empty partitions on an ALP MVC that is being reclaimed INPLACE are freed. Additionally, free space on VLE VMVCs becomes available.

CONMVC(nn)

optionally, specifies the maximum number of MVCs that VTCS concurrently processes for both drain and reclaim.

nn indicates the number of MVCs. Valid values are 1 to 99. If not specified, the default is the CONMVC value specified on the CONFIG RECLAIM statement.

ELAPSE(nnnn)

optionally, specifies the maximum time for the reclaim in minutes. If the maximum time expires, VTCS issues message SLS6682I. If there are no MVCs currently mounted, reclaim stops when the ELAPSE value is reached. If any MVCs are currently mounted when the ELAPSE value is reached, reclaim processes the mounted MVCs and then stops.

nnnn indicates the reclaim time in minutes. Valid values are 1 to 1440. If not specified, there is no time limit on the reclaim process.

NOWAIT

optionally, specifies that the utility does not wait for the operation to complete and returns after the request is submitted.

RECONcil

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The RECONcil command reconciles VTV media and location (moves VTVs from one Storage Class to another).

RECONcil performs a series of cross-checks between the MVCs, VTVs, STORCLAS and MGMTCLAS definitions.

RECONCIL has two phases:

In the first phase, VTCS selects MVC and Storage Classes to be checked. MVCs are checked to ensure they meet the Storage Class definitions and ACS definitions. If inconsistencies are found, then the VTVs on those MVCs are added to the list of VTVs to be recalled and re-migrated to give correct MVC, ACS and Storage Class copies for that VTV. The RECONcil parameters STORCLAS and MVC limit the checking in this phase.
In the second phase, VTCS selects the VTVs and Management Classes to establish the correct number and location of VTV copies. Any VTVs with inconsistencies are added to the list of VTVs to be recalled and re-migrated. The RECONcil parameters MGMTCLAS and VTV limit the checking in this phase.

Syntax

Figure 3-132 shows RECONcil command syntax.

Figure 3-132 RECONcil command syntax

Surrounding text describes Figure 3-132 .

Parameters

The STORclas and MVC parameters limit the first phase of checking to the specified Storage Classes or MVCs. If STORclas or MVC are not specified, VTCS checks all MVCs by default.

As shown in Figure 3-132, the RECONcil command includes the following parameters:

STORclas(stor-class-name1...stor-class-namen)

optionally, specifies one or more Storage Classes.

stor-class-name1...stor-class-namen indicates one or more Storage Classes.

MVC(mvc-list or mvc-range)

a list or range of MVCs. This parameter is mutually exclusive with STORclas.

mvc-list or mvc-range indicate a list or range of MVCs.

MGMTclas(mgmt-class-name1...mgmt-class-namen)

optionally, specifies one or more Management Classes. This parameter is mutually exclusive with VTVid.

mgmt-class-name1...mgmt-class-namen indicates one or more Management Classes.

VTV(vtv-list or vtv-range)

optionally, specifies a list or range of VTVs. This parameter is mutually exclusive with MGMTclas.

vtv-list or vtv-range indicates a list or range of VTVs.

MAXMVC(nn)

optionally, specifies the maximum number of MVCs that will be processed by a single reconciliation task.

nn indicates the number of MVCs. Valid values are 1 to 98. If not specified the CONFIG RECLAIM value (or default) is used. This parameter is ignored if MOVEVTV is not specified.

CONMVC(nn)

optionally, specifies the maximum number of MVCs that VTCS concurrently processes during subsequent recall and migrate operations.

nn indicates the number of MVCs. Valid values are 1 to 99. If not specified the CONFIG RECLAIM value (or default) is used. This parameter is ignored if MOVEVTV is not specified.

ELAPSE(nnnn)

optionally, specifies the maximum time for the reconciliation in minutes. If the maximum time expires, VTCS issues message SLS6682I. If there are no MVCs currently mounted, reconciliation stops when the ELAPSE value is reached. If any MVCs are currently mounted when the ELAPSE value is reached, reconciliation processes the mounted MVCs and then stops.

nnnn indicates the time in minutes. Valid values are 1 to 1440. If not specified, there is no time limit on the reconciliation process. This parameter is ignored if MOVEVTV is not specified.

PLICYdd(ddname)

optionally, specifies the DD name of a file containing an alternate MGMTclas statement. This parameter is mutually exclusive with MOVEVTV.

ddname indicates the DD name.

MOVEVTV

optionally, move VTVs per the currently active Management Policies as specified by the MGMTclas statements that apply to the VTVs. If you do not specify MOVEVTV, only a report is generated. (no VTVs are moved). This parameter is mutually exclusive with POLICYdd.

RECONcil Reports

Fields

The RECONcil report includes the following fields:

VTV volser: the VTV volser.
Size (MB): The uncompressed size of the VTV (MB). <MOUNT> indicates that the VTV was mounted when the report ran. <FENCED> indicates that the VTV's state is unknown. If <FENCED> appears, contact Oracle StorageTek Software Support.
Comp %: The VTV compression percentage achieved. This is the difference between the uncompressed and compressed VTV size expressed as a percentage of the uncompressed VTV size. For example if a 100 MB VTV compresses to 40 MB then the compression% will be given as 60%. A compression of 0% indicates that no compression was possible on the VTV.
Creation Date and Time: The date and time that the VTV was created.
MGMT Class: The name of the Management Class for the VTV specified.
MVC1, MVC2, MVC3, MVC4: The MVC(s) affected as a result of the Reconcil.
Tapeplex: The TapePlex name.
Reason: The reason for the VTV selection: media type, media location, migration (space release), immediate migration, or Storage Class.

The RECONcil Tapeplex Report section displays the number of candidate VTVs and Total VTV size (MB) for each TapePlex.

MVC Report Fields

The following list describes the RECONcil MVC report fields. The data for each MVC is followed by one or more VTV volsers with copies on the MVC. This section of the report is followed by a total line showing the number of candidate MVCs and the size in MB to be recalled and remigrated:

MVC Volser: The MVC volser.
MVC Media Type: The MVC type.
Media Size (MB): The size of the MVC (MB). This will only be determined after VTCS has used an MVC. UNKNOWN appears in this field until VTCS migrates a VTV to the MVC.
Storage Class/Consolidate time: The MVC's Storage Class or time the VTVs on it were consolidated.
Candidate VTVs: The number of candidate VTVs on the MVC.
Total VTV Size (MB): The size of all candidate VTVs on the MVC in MBs.
Location (ACS ID): The ACS where the MVC resides. If blank, the MVC is not currently in an ACS.

RECOVer

Interfaces:

Console or PARMLIB
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The RECOVer command recovers the resources owned by a host that becomes inoperable. Cross-host recovery frees library resources that are owned by the failing host, and transfers that ownership to the recovering host. These resources include CAPs, which can be activated by only one host at a time, and volumes, which are assigned to a particular host while moving or mounting.

Syntax

Figure 3-133 shows RECOVer command syntax.

Figure 3-133 RECOVer command syntax

Surrounding text describes Figure 3-133 .

Parameters

As shown in Figure 3-133, the RECOVer command includes the following parameters:

host-id: identifies the host for which to perform recovery (the SMF system identifier for both JES2 and JES3).
FORCE: optionally, indicates that recovery is to be performed for the specified host even if the HSC has not detected that the host is inactive. This enables the recovery of a host when the active flag for that host is still on.

Caution:

Use the FORCE operand with great caution. Make sure the specified host is inactive before specifying this operand. Forced recovery of an active host requires that the HSC on that host be recycled. All database activity is prohibited on the recovered host, which can cause unexpected abends when tape activity occurs, or when the HSC is recycled on that host.

RELease

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The RELease command frees an allocated CAP, making it available for other processes, without requiring a recycle of all HSCs sharing the control data set.

A CAP can be left allocated to a host if the HSC on that host terminated without performing recovery while the CAP was active.

This command can be issued from any connected host. The operator is required to confirm the release operation by responding to a console message.

Caution:

Use this command as a last resort. Make sure the CAP is not being used by another active process. Issuing the RELease command on an active CAP may cause the process using the CAP to receive errors.

Syntax

Figure 3-134 shows RELease command syntax.

Figure 3-134 RELease command syntax

Surrounding text describes Figure 3-134 .

Parameters

As shown in Figure 3-134, the RELease command includes the following parameters:

cap-id: identifies the CAP to be released. The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

Note:
The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

REPLaceall

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The REPLaceall command deletes the scratch list in the CDS and optionally replaces it with a new list.

Syntax

Figure 3-135 shows REPLaceall command syntax.

Figure 3-135 REPLaceall command syntax

Surrounding text describes Figure 3-135 .

Parameters

As shown in Figure 3-135, the REPLaceall command includes the following parameters:

VOLser(vol-list)

optionally, specifies the list of volume serial numbers to be added, deleted, or replaced in the scratch list(s).

vollist indicates the volume serial numbers; this can be a single volume, a list of volume serial numbers, ranges of volume serial numbers, or combinations of lists with ranges delimited by commas. The entire list must be enclosed in parentheses.

RESTore

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

HSC must be down (inactive)

Description

The RESTore command restores, or re-creates the library Control Data Set (CDS) from a previous CDS backup copy. If multiple CDS DD statements are specified, then multiple CDS copies are created in the RESTore process.

Caution:

It is critical that you restore all data sets referenced by the HSC (primary, secondary, standby). Failing to restore all data sets can cause CDS mismatches. Refer to Oracle's ELS publication Managing HSC and VTCS for detailed information about when to use this utility and how it functions.

Syntax

Figure 3-136 shows RESTore command syntax.

Figure 3-136 RESTore command syntax

Surrounding text describes Figure 3-136 .

Parameters

None.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the RESTore JCL:

SLSCNTL

specifies the primary CDS.

SLSCNTL2

optionally, specifies the secondary CDS.

If a secondary CDS exists, include this statement so that if a switch occurs and the secondary CDS becomes active, the CDSs can be reordered to maintain database integrity.

SLSSTBY

optionally, specifies the standby CDS.If a standby CDS exists, include this statement so that if a switch occurs and the standby CDS becomes active, the CDSs can be reordered to maintain database integrity.

SLSBKUP

the backup data set.

SCRAtch

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC at FULL service level

Description

The SCRAtch command scratches one or more volumes.

Syntax

Figure 3-137 shows SCRAtch command syntax.

Figure 3-137 SCRAtch command syntax

Surrounding text describes Figure 3-137 .

Parameters

As shown in Figure 3-137, the SCRAtch command includes the following parameters:

VOLser(vol-list)

specifies the list of volume serial numbers to be added, deleted, or replaced in the scratch list(s).

SCREdist

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The SCREdist command redistributes, or balances, the number of scratch volumes across the library.

SCREdist permits the redistribution of scratch volumes either:

among LSMs implied by the specification of an ACS, or
among the LSMs explicitly identified through an optional parameter.

SCREdist enables you to select one media type and recording technique. If specified, scratch volume redistribution will be based on the MEDia and RECtech settings.

If neither MEDia nor RECtech is specified, volumes are redistributed without regard to media type or recording technique.

When only the ACS parameter is specified, the redistribution method transfers cartridges from LSMs with a greater number of scratch volumes to LSMs with a lesser number of scratch volumes. The process is repeated until the number of scratch volumes in each LSM is within the defined scratch tolerance level.

Distribution in an ACS containing a mix of LSMs (4410s, 9310s, 9360s, 9740s) is performed based on a percentage of scratch cartridges in the ACS. That is, the utility causes each LSM to have the same percentage of scratch tapes within the ACS as the LSM has cells within the ACS. For example, in an ACS where a 9310 LSM contains 80 percent of the cells within the ACS, 80 percent of the scratch tapes will reside in the 9310.

Note:

The SL3000 and SL8500 are standalone libraries and cannot be combined with any other LSM type.

After Scratch Redistribution is completed, only the specified LSMs contain scratch cartridges, if the LSM parameter was specified.

Concurrent redistributions among different ACSs are accomplished by multiple executions of this utility program.

Redistribution moves non-scratch cartridges to make space for scratch cartridges. The actual number of scratch cartridges moved may vary depending on the number of free cells and the number of scratch cartridges available.

Note:

Cartridges cannot be transferred to a frozen panel.

Syntax

Figure 3-138 shows SCREdist command syntax.

Figure 3-138 SCREdist command syntax

Surrounding text describes Figure 3-138 .

Parameters

As shown in Figure 3-138, the SCREdist command includes the following parameters:

ACS(acs-id)

specifies one ACS in the library in which the scratch volumes are to be redistributed.

acsid indicates the ACS. The one or two digit decimal ACS identifier.

LSM(lsm-list)

optionally, specifies that only certain LSMs within an ACS are to contain scratch cartridges (if not specified, scratch volumes are redistributed across all LSMs in the ACS).

lsmlist indicates a single LSM or a list of LSMids. An LSMid (lsm-id) is made up of the ACSid (decimal 00-99) and the LSM number (decimal 00-99) separated by a colon (:). An LSM range is not allowed.

The element(s) contained in an lsmlist must be enclosed in parentheses; multiple elements must be separated by blanks or commas.

SUBpool(subpool-name)

optionally, specifies the subpool name from which scratch volumes are to be redistributed.

subpoolname indicates the subpool.

BALtol(tolerance-value)

optionally, specifies a balance tolerance value. Scratch volumes are distributed based on this specified value.

tolerancevalue indicates a percent value that identifies when cartridge redistribution ends. Valid values are 1 through 999, where the values indicate a percentage from .1 to 99.9 (i.e., 1 signifies .1 percent; 999 equals 99.9 percent). The initial value for the HSC is 1. If tolerancevalue is not specified in this utility, HSC uses the initial value for scratch redistribution.

The utility finishes redistributing scratch cartridges when the percentage of scratch tapes in all specified LSMs is within tolerancevalue / 2 percentage points of each LSM's percentage of cells in the ACS.

For example, assume an ACS has one 4410 LSM with 5,000 cells, one 9360 (WolfCreek) LSM with 1,000 cells, and 600 total scratch tapes in the ACS. Scratch Redistribution attempts to put 500 scratches in the 4410 and 100 scratches in the 9360.

Entering BALtol(100) specifies a setting of 10 percent, which means that the utility ends when all LSMs are within ±5 percent of the expected number of scratches for each LSM (500 for the 4410, 100 for the 9360).

The expected number can be determined as follows:

expnumlsm=totscracs x (totcellslsm/totcellsacs)

where:

expnumlsm indicates the expected number of scratches for each LSM.
totscracs indicates the total number of scratches in the ACS.
totcellslsm indicates the total number of cells in the LSM.
totcellsacs indicates the total number of cells in the ACS.

In the previous example, the 4410 should have a range 470530 scratches and the 9360 a range of 70130. To determine the BALtol range:

BALtol range = expnumlsm + (baltol/1000 x totscracs) \ 2

where:

BALtol range indicates the range of balance tolerance value.
expnumlsm indicates the expected number of scratches for each LSM (see above).
baltol indicates the usersupplied percent value (tolerance-value) that specifies when scratch cartridge redistribution ends.
totscracs indicates the total number of scratches in the ACS.

MEDia(media-type)

optionally, specifies the type of cartridge to redistribute across the ACS.

media-type indicates the media type

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

RECtech(recording-technique)

optionally, specifies the method used to record data tracks on the tape surface.

Note:

If RECtech is not specified, the next scratch cartridge is selected depending on the MEDia type that has been specified.

recording-technique indicates the recording technique. See Appendix A, "MEDia, RECtech, and MODel Values" for valid recording-technique values.

Fields

The SCRPT report includes the following fields:

Storage Class

The Storage Class.

STORMNGR

The VLE subsystem name.

NODE

The server node.

Total MVCs

Total count of VMVCs in this grouping.

Capacity (Gb)

Total capacity in Gbs of all VMVCs in this grouping.

Used (Gb)

Total Gbs of used VMVC space in this grouping.

Compressed (Gb)

Total Gbs of compressed data in this grouping, which is equal to the size of the data as the VTSS compresses it (at a 4:1 ratio) and writes it to a VTV.

Uncompressed (Gb)

Total Gbs of uncompressed data in this grouping, which equals the original size of the data before the VTSS compresses it and writes it to a VTV.

Reduction Ratio

The approximate reduction ratio for the data, which is Uncompressed Gb divided by Used Gb. The Reduction Ratio, therefore, includes both VTSS compression and VLE deduplication. A larger reduction ratio indicates more effective compression and deduplication. For example, the VTSS receives 16 Mb of data, compresses it to 4Mb, and writes the compressed data to a VTV. VLE subsequently deduplicates the VTV to 2Mb and writes it to a VMVC. Thus, the reduction ratio is 16Mb2Mb or 8.0:1.

Because the calculation is done using Mb, it is possible to see 0Gb in the Used or Uncompressed fields, yet see a reduction ratio other than 1.0:1.

SENter

SET CLNPRFX

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET CLNPRFX command sets a cleaning prefix.

Note:

HSC must be shut down on all systems before changing the cleaning prefix.

Syntax

Figure 3-141 shows SET CLNPRFX command syntax.

Figure 3-141 SET CLNPRFX command syntax

Surrounding text describes Figure 3-141 .

Parameters

As shown in Figure 3-141, the SET CLNPRFX command includes the following parameters:

prefix: indicates a 3character prefix for the cleaning cartridges. Valid characters are AZ, 09, $, #, and @.

Note:
HSC must be shut down on all systems before changing the cleaning prefix.

SET CLNPRFX Procedure

To change a cleaning cartridge prefix:

Eject all cleaning cartridges from all ACSs. The HSC records information about cleaning cartridges in the CDS.
Terminate the HSC on all hosts.
Change the cleaning prefix using SET CLNPRFX.
Initialize the HSC on any desired hosts.
Enter new cleaning cartridges identified with the new prefix into all ACSs.

Note:

It is preferable to enter new cleaning cartridges because a cartridge's select count is set to zero when it is ejected and reentered. The select count tracks the number of times a cleaning cartridge has been used.

SET COMPRFX

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET COMPRFX command sets a HSC/VTCS command prefix.

Syntax

Figure 3-142 shows SET COMPRFX command syntax.

Figure 3-142 SET COMPRFX command syntax

Surrounding text describes Figure 3-142 .

Parameters

As shown in Figure 3-142, the SET COMPRFX command includes the following parameters:

cmdhex

indicates the 2character hexadecimal code of the command prefix. Do not choose a value that conflicts with values assigned to other subsystems. The characters associated with each code are shown in Table 3-14.

The command prefix is not valid until the HSC or VTCS system is recycled.

Make sure that the prefix character used does not conflict with any of the following:

another subsystem's command prefix character (such as $ for JES2 or * for JES3, or ; the delimiter for TSO).
the command delimiter for MVS, specified as the value for the CMDDELIM keyword in SYS1.PARMLIB (CONSOLxx) and described in the IBM z/OS Installation and Tuning Guide.
a JES line editing character as specified in the JES installation statements or default. For JES2 the initialization statement is CONDEF.
For JES3 the installation statement is CONSTD. Descriptions of these statements and default values can be found in the appropriate IBM z/OS JES3 Installation and Tuning Guide.

If you are running the HSC on a VM host that shares the CDS with a HSC running on MVS, make sure that your command prefix character does not conflict with any of the VM facilities, such as the CP line editing symbol. The following table maps command prefix codes to characters:

SET FREEZE

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET FREEZE command specifies whether to disallow (freeze) or allow (unfreeze) additional cartridges to be stored on a panel or LSM.

Syntax

Figure 3-146 shows SET FREEZE command syntax.

Figure 3-146 SET FREEZE command syntax

Surrounding text describes Figure 3-146 .

Parameters

As shown in Figure 3-146, the SET FREEZE command includes the following parameters:

ON

specifies to freeze a panel or LSM, which prevents additional cartridges from being moved to it. This restriction includes allocating new cartridge locations on a panel or LSM as a result of the following:

a MOVe command, utility, or PGMI request
cartridge entry into the ACS
float, scratch dismount, or scratch redistribution processing.

If a cartridge on a frozen panel is selected (e.g., through a mount request), it may be returned to its home cell on the frozen panel after fulfilling the request.

Cartridges already located on a frozen panel or LSM must be deliberately moved off using the MOVe command, utility, or PGMI request, or cartridges can be ejected by running the EJECt command or EJECt utility.

OFF

specifies to unfreeze a panel or LSM, which enables additional cartridges to be moved to it.

FORLSMID(lsm-id)

specifies that the operation is being restricted to a specific panel or LSM.

lsm-id indicates the LSMid (AA:LL) of the LSM being frozen or unfrozen. An LSMid (lsm-id) is made up of the ACSid (decimal 00-99) and the LSM number (decimal 00-99) separated by a colon (:).

FORPANEL(panel)

optionally, specifies that the operation is being restricted to a specific panel.

panel indicates the 2-digit ID of the panel to be frozen or unfrozen. The specified panel must be an existing drive panel in the LSM. See "Panels" for a list of valid values.

Note:

If frozen panels already exist in an LSM, and then you freeze the entire LSM, all panels will be unfrozen when you unfreeze the LSM.

If you want some panels to remain frozen after unfreezing the entire LSM, you can add SET FREEZE ON FORLSMID FORPANEL statements to the same SLUADMIN JOBSTEP.
When an LSM is frozen, no new cell allocations occur. However, any cartridge from the frozen LSM that is currently mounted on a drive will return to its home cell.
Frozen or unfrozen panels and LSMs are recognized immediately by all active HSCs. It is not necessary to stop and reinitialize active HSCs to detect changes made by SET FREEZE.

On a frozen panel, if a panel type is changed by running the MERGEcds or Reconfiguration utility, the new panel is not frozen. If the panel type did not change, the panel remains frozen after a merge or reconfiguration.

SET HOSTID

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET HOSTID command renames a host ID.

Note:

If other hosts are active at the time of the host name change, some messages on those active hosts may display the old host name. After the HSC is restarted on those hosts, the new host name appears in the messages.

Syntax

Figure 3-147 shows SET HOSTID command syntax.

Figure 3-147 SET HOSTID command syntax

Surrounding text describes Figure 3-147 .

Parameters

As shown in Figure 3-147, the SET HOSTID command includes the following parameters:

HOSTID(newhost)

specifies that the old host ID is being changed to a new name.

newhost indicates a 18 character host ID, which represents the SMF system ID for both JES2 and JES3. newhost cannot already be defined in the CDS.

FORHOST(oldhost)

specifies the old host ID.

oldhost indicates a 1to 8character host ID. This host must not be marked active in the CDS. A HSC can be down but still marked active. SET HOSTID would fail to run. To be marked inactive, the HSC, in the host that is down, must be brought up and then shut down. Also, another host could perform crosshost recovery on the HSC that is down, but marked active. Either of these change the status in the CDS of the down HSC from active to inactive. See "SET HSCLEVel" for information about resetting operating flags.

Note:

You must delimit the HOSTID (newhost or oldhost) with quotes when this ID is in lower case.

SET HSCLEVel

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET HSCLEVel command clears HSC active and release level indicators for a designated host.

Note:

If used, HSCLEVel should be performed only when the host designated in hostid is inactive.

These indicators remain set after an abrupt termination of the HSC has occurred. For example, a cancellation of the HSC or a crash of the operating system.

Syntax

Figure 3-148 shows SET HSCLEVel command syntax.

Figure 3-148 SET HSCLEVel command syntax

Surrounding text describes Figure 3-148 .

Parameters

As shown in Figure 3-148, the SET HSCLEVel command includes the following parameters:

OFF

specifies that the HSC active and HSC release level indicators for the designated host are to be cleared.

FORHOST(host-id)

specifies that the active indicators are to be cleared for the designated host.

hostid indicates the 1 to 8character host ID of the host to which the operation is restricted.

Note:

Oracle recommends the following alternatives to executing SET HSCLEVel because they reset the HSC indicators and recover resources owned by the failing host:

Restart the HSC on the host.
Enter the RECover hostid FORCE operator command.

SET LOGFILE

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET LOGFILE command is part of the HSC Transaction Logging Service, introduced in HSC 7.0.

This command defines primary and secondary log files used by the HSC transaction logging service to record VTCS logical transactions necessary to recover the CDS.

If it becomes necessary to restore a CDS, the information in these log files can be used to reduce the amount of time required to restore the VTCS data in the CDS back to the proper state.

Note:

Log files must be pre-formatted using the FMTLOG utility. See "FMTLOG" for more information.
If logging is not currently active, log file names specified in the SET LOGFILE command are activated immediately.
If logging is currently active, you must run the OFFload LOGFILE utility using the OFFload LOGFILE command to change the log files. See "OFFload" for more information.

Syntax

Figure 3-149 shows SET LOGFILE command syntax.

Figure 3-149 SET LOGFILE command syntax

Surrounding text describes Figure 3-149 .

Parameters

As shown in Figure 3-149, the SET LOGFILE command includes the following parameters:

primary-log-file-dsn

the data set name for the primary log file. This parameter is required.

OFF

Specify OFF in place of the primary-log-file-dsn to indicate that logging should be terminated. Logging will continue on the HSC subsystem until you run OFFload LOG, unless you also specify the IMMED parameter.

IMMED: specifies that logging should be immediately stopped on all active HSC subsystems. When IMMED is specified, any previous log data cannot be offloaded.

secondary-log-file-dsn

optionally, the data set name for the secondary log file. This parameter is required if a secondary log file was previously defined.

When changing only the secondary log file data set name, you must re-specify the existing primary log file data set name in the primary log file data set name position.

OFF

Specify OFF in place of the secondary-log-file-dsn to change from duplex to simplex logging.

SET MAJNAME

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required. HSC must be shut down on all systems before changing the QNAME.

Description

The SET MAJNAME command sets the ENQ/DEQ/RESERVE QNAME.

Syntax

Figure 3-150 SET MAJNAME command syntax

Surrounding text describes Figure 3-150 .

Parameters

As shown in Figure 3-150, the SET MAJNAME command includes the following parameters:

qname: a 1 to 8character QNAME. The QNAME is blank padded on the right. The name should conform to the requirements for a QNAME. If any hosts are MVS hosts, to prevent conflicts with the operating system, the QNAME should not start with SYSA through SYSZ. Since the HSC is authorized, the SYSA through SYSZ names would be allowed, but deadlock may result.

Note:

HSC must be shut down on all systems before changing the QNAME.

SET MIGOPT

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The SET MIGOPT command changes the following migration parameters:

nn indicates the new low AMT as a percent of VTSS space. Valid values are 5 to 95 and must be less than the HIGHthld value.

SET NEWHOST

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET NEWHOST command defines a new host.

Syntax

Figure 3-152 shows SET NEWHOST command syntax.

Figure 3-152 SET NEWHOST command syntax

Surrounding text describes Figure 3-152 .

Parameters

As shown in Figure 3-152, the SET NEWHOST command includes the following parameters:

newhost

a 18 character host ID, which represents the SMF system ID for both JES2 and JES3.

The new host to be added cannot exceed the maximum limitation of 16 hosts.
newhost cannot already be defined in the CDS.
You must delimit the HOSTID with quotes when newhost is in lower case.

SET RMM

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The SET RMM command enables or disables the VTCS to DFSMSrmm interface.

Syntax

Figure 3-153 shows SET command syntax.

Figure 3-153 SET RMM command syntax

Surrounding text describes Figure 3-153 .

Parameters

As shown in Figure 3-153, the SET RMM command includes the following parameters:

ENable: enables the VTCS to DFSMSrmm interface. With the interface enabled, VTCS communicates with DFSMSrmm on all scratch mounts and scratch requests of VTVs whose Management Class specifies DELSCR(YES).
DISable: disables the VTCS to DFSMSrmm interface. With PTF L1H139T installed, the interface is automatically disabled at VTCS initialization.

If you do not specify a parameter, VTCS displays the current setting of the interface.

Note:

Enabling the DFSMSrmm interface is required only for sites that do not have IBM APAR OA03368 applied and the following (minimum) VTSS microcode levels installed:

VSM3: N01.00.65

VSM4: D01.00.03

VSM5: all microcode levels have the required change
If required, Oracle recommends adding the VTCS SET RMM ENA command to the SLSSYSxx PARMLIB member read at HSC initialization.
Enabling this interface can cause delays in scratch mount processing.

SET SCRLABL

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET SCRLABL command specifies the scratch label type.

To add to the scratch pool, the REPLaceall function is run before the Scratch Update utility. Otherwise, the Scratch Update utility should be run to update the scratch pools after using this function.

Syntax

Figure 3-154 shows SET SCRLABL command syntax.

Figure 3-154 SET SCRLABL command syntax

Surrounding text describes Figure 3-154 .

Parameters

As shown in Figure 3-154, the SET SCRLABL command includes the following parameters:

SL: specifies that nonspecific requests for standardlabeled tapes are to be automated.
AL: specifies that nonspecific requests for ANSIlabeled tapes are to be automated.
NL: specifies that nonspecific requests for nonlabeled tapes are to be automated.
NSL: specifies that nonspecific requests for nonstandard labeled tapes are to be automated.

SET SLIDRIVS

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET SLIDRIVS command adds or changes device numbers for drives in a particular panel.

For 9310 and 9740 libraries, these changes take effect when you recycle the affected HSC system(s). See "Running SET SLIDRIVS With the HSC Active" for more information.
For SL3000 and SL8500 libraries, these changes take effect when you issue a MODIFY CONFIG UPD ACS(XX) for the ACS that the drives were added to. NCO adds the drives to the configuration. There is no need to recycle the HSC.

Caution:

For 9310 and 9740 libraries, Oracle recommends you bring the HSC down on all hosts before specifying this parameter, and recycle the HSC after every SET SLIDRIVS operation. Table 3-15 describes some instances where the HSC can remain active, however, unpredictable results can occur.

Syntax

Figure 3-155 shows SET SLIDRIVS command syntax.

Figure 3-155 SET SLIDRIVS command syntax

Surrounding text describes Figure 3-155 .

Parameters

As shown in Figure 3-155, the SET SLIDRIVS command includes the following parameters:

addr0,...addr31

the device numbers for the panel. The numbers are from the top of the panel down. If a device number is omitted, this means that the host cannot access a drive in that particular position in the panel, or the drive does not exist. Blanks as well as commas may be used to separate the drive specifications.

The total number of drives specified (including comma placeholders) must be:

4, 10, or 20 for a 9310
16 for an SL8500
8, 16, 24 or 32 for an SL3000
You cannot specify 20-drive panels on 9740 (TimberWolf) LSMs or SL8500 libraries.
10drive and 20drive panels cannot be specified on 4410 LSMs.

Before this utility can be executed, all cells in the panel must be empty if the user is moving to or from a 20drive panel configuration.

The user can change a drive panel between a 4 or 10drive panel (normal) and a 20drive panel (wide) without running a reconfiguration. Affected panels must be empty and no cells in the panels can be allocated to cartridges.

To make sure that drive panels being changed from normal to wide configurations (or vice versa) remain empty, freeze them with the SET FREEZE utility. Then, move all cartridges to other panels or LSMs.

If a panel type is changed by SET SLIDRIVS, the new panel will not be frozen. Frozen panels whose panel type did not change remain frozen after SET SLIDRIVS.

HSC does not allow duplicate addresses for drives. If it becomes necessary to exchange the drive addresses on one panel with the drive addresses on another panel, the addresses on one of the panels must first be changed to temporary addresses that are not currently defined. For example:

LSM00, PANEL10, ADDRESSES400,401,402,403
LSM01, PANEL11, ADDRESSES404,405,406,407

If the 400403 addresses are to be moved to LSM01 and 404407 are to be moved to LSM0, the SET utility must first be run to change the LSM0 addresses (400403) to 900903 (or some other addresses that are not currently defined). The SET utility is then run to change the LSM01 addresses to 400403. The utility is run a third time to change the temporary LSM0 addresses (900903) to 404407.

On all 9310 LSMs, drives are defined to the HSC from top to bottom, with addr0 representing the topmost drive and addrn the bottommost drive.

However, on a 9740 10drive panel LSM, the drives are populated and configured to the 9740 LSM from bottom to top. (9740 4drive panels are configured to the 9740 LSM from top to bottom, as are all other LSM drive panels.)

An example showing how to define a 9740 10drive panel containing five 9840 drives is:

SET SLIDRIVS(,,,,,BD4,BD3,BD2,BD1,BD0),FORLSMID(lsm-id),
              FORPANEL(panel)

For the SL3000, drives are defined from top to bottom, right to left, as looking from the front to the back of the library.

For the SL8500, drives are defined from top to bottom, right to left, as viewed from the outside of the library.

FORLSMID(lsm-id)

specifies that the operation is being restricted to a specific LSM.

lsmid indicates the LSMid (AA:LL) containing the drive panel whose addresses are being changed. An LSMid (lsm-id) is made up of the ACSid (decimal 00-99) and the LSM number (decimal 00-99) separated by a colon (:).

FORPANEL(panel)

specifies that the operation is being restricted to a specific panel.

panel indicates the 2digit ID of the panel containing the drives whose addresses are being changed. See "Panels" for a list of valid values.

Note:

The specified panel must be an existing drive panel in the LSM.

MODEL(model-type)

optionally, specifies the transport model number.

model-type indicates the model type.

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid model-type values.

Note:

The MODEL parameter is only used to specify the drive type for manual RTDs., which are defined in a nonexistent ACS. When an LSM is brought online, the (non-manual) drive type is automatically set.

FORHOST(host-id)

specifies that the operation is being restricted to a specific host. Only the specified hosts' drive device numbers are set. If omitted, the device numbers for all hosts are changed.

hostid indicates the 1 to 8character host ID of the host, to which the operation is restricted.

Note:

The number of drive positions for a specific host must equal the number of drive positions defined globally (issuing SET SLIDRIVS without the FORHOST parameter).

Running SET SLIDRIVS With the HSC Active

The following applies to 9310 and 9740 LSMs only. It does not apply to the SL8500 or SL3000.

Ideally, the HSC should be shut down on all hosts when you specify the SET SLIDRIVS parameter. In some cases, however, the HSC can be left active without causing adverse results. Table 3-15 defines options for running SET SLIDRIVS.

Table 3-15 HSC State/SET SLIDRIVS Operation

HSC State	Effect on SET SLIDRIVS
Down	If the HSC is down on all hosts, the HSC recognizes all new drive locations when it is initialized.
Active	The HSC can be up on all hosts only if new drives are being added at new drive locations. The HSC recognizes the new drive locations when it is recycled on a host.
Active	If unit addresses are changed or deleted for an existing drive location, either the affected LSM must be offline until the HSC has been recycled on all hosts, or the affected ACS must be offline to all affected hosts that access an HSC that has not been recycled.

SET SLIDRIVS Procedure

The following procedures show one method for changing unit addresses with the HSC active.

For the 9310 and 9740:

For one host:

Modify the affected LSM offline (MODify lsmid OFFline). The LSM will be offline to all hosts.
Use SET SLIDRIVS to update the CDS drive records while the Oracle StorageTek CSE(s) is making the hardware changes.
Recycle the HSC on one host.
Vary the affected ACS offline (Vary ACS(acsid) OFFline) on all hosts running an HSC that has not been recycled.
Modify the affected LSM online (MODify lsmid ONline). The LSM will be online to all hosts where the ACS is online. Only hosts that are online to the ACS and running a recycled HSC will mount to drives connected to this LSM.

For the remaining hosts, recycle the HSC, and the affected ACS will come up.

For the SL3000 and SL8500:

Make necessary hardware changes (add/delete/move drives).
Modify the SET SLIDRIVS JCL deck to reflect the changes.
Run SET SLIDRIVS.
Issue MODIFY CONFIG (or MODIFY CONFIG ACS(xx))

The changes will cascade to all other hosts.

SET SLISTATN

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET SLISTATN command adds or changes LMU station addresses in an ACS. The change does not take effect until the affected HSC(s) is recycled.

An affected HSC is one that resides in the host specified in FORHOST. If FORHOST is omitted, all HSCs are relevant because the operation is not restricted to a specific host.

Syntax

Figure 3-156 shows SET SLISTATN command syntax.

Figure 3-156 SET SLISTATN command syntax

Surrounding text describes Figure 3-156 .

Parameters

As shown in Figure 3-156, the SET SLISTATN command includes the following parameters:

stat1,...,stat16

the LMU station addresses associated with a particular ACS. No station addresses are required. Up to 16 can be specified, separated by commas.

When adding one or more station addresses to an existing list of stations, you must specify all old stations as well as new ones. Any stations (for this ACS and Host ID) not specified here will be deleted and no longer available for use.

To remove station addresses for an ACS or host, do not specify station addresses following the SLISTATN parameter. For example:

SET SLISTATN(),FORACS(01),FORHOST(HSCA)

FORACS(acs-id)

specifies the ACS for which station addresses are being changed.

acsid indicates the ACSid whose stations are being changed (00 FF).

FORHOST(host-id)

specifies that the operation is being restricted to a specific host. Only the specified hosts' stations are set. If omitted, the stations for all hosts are changed.

hostid indicates the 1 to 8character host ID for the host to which the operation is restricted.

SET SMF

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET SMF command adds a new SMF record type for HSC.

Until the HSC is recycled on all CPUs, the ACTIvities command produces incorrect results because some HSC systems are writing records with the old SMF type, and some with the new record type.

Syntax

Figure 3-157 shows SET SMF command syntax.

Figure 3-157 SET SMF command syntax

Surrounding text describes Figure 3-157 .

Parameters

As shown in Figure 3-157, the SET SMF command includes the following parameters:

libtype

the SMF record type. The range is from 0 to 255, inclusive.

Since 128 through 255 are for userdefined records, it is recommended that a number from 128 through 255 be chosen, and that the number does not conflict with other userdefined record types.

SET TAPEPlex

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET TAPEPlex command sets a TapePlex name.

Syntax

Figure 3-158 shows SET TAPEPlex command syntax.

Figure 3-158 SET TAPEPlex command syntax

Surrounding text describes Figure 3-158 .

Parameters

As shown in Figure 3-158, the SET TAPEPlex command includes the following parameters:

tapeplex-name

the 1-8 character TapePlex name.

The TapePlex name must start with an alphabetic or numeric character. Remaining characters may be letters, numbers, or hyphens, however, a hyphen may not be the last character. You can specify a NULL value (TAPEPLEX()) to allow the TapePlex name to be set automatically by the next SMC transaction.

Note:

This name must match the TapePlex name specified on the SMC TAPEPlex command on ALL SMC systems that communicate with this HSC system. See "TAPEPlex" for more information about the SMC TapePlex command.

SET TCHNIQE

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET TCHNIQE command sets the control data set recovery technique. This replaces the recovery technique currently defined in the CDS.

Refer to Oracle's ELS publication Configuring HSC and VTCS for information about the LIBGEN SLIRCVRY macro. A recovery technique value must be specified. There is no default value.

Syntax

Figure 3-56 shows SET TCHNIQE command syntax.

Figure 3-159 SET TCHNIQE command syntax

Surrounding text describes Figure 3-159 .

Parameters

As shown in Figure 3-159, the SET TCHNIQE command includes the following parameters:

NONE: specifies no form of recovery is used for the control data set. Thus, the primary control data set must be rebuilt, if inaccessible.
SHADOW: specifies that there is to be two distinct copies of the control data set (primary and secondary) for recovery purposes. It is recommended that these data sets reside on separate HDAs and separate strings. A journal is not recorded.
STANDBY: specifies that primary, secondary, and standby control data sets are to be recorded for recovery purposes. No journals are recorded during HSC operation.

SET TCHNIQE Procedure

Use the following procedure to invoke the TCHNIQE utility and to set the appropriate recovery technique value:

ALLOCATE, based on existing CDS definitions, any new CDS copies that will be needed for the subsequent SET recovery technique.
Stop the HSCs on all hosts configured to use the CDS you are intending to update with SET recovery technique.
Run the BACKup utility.
Run the RESTore utility to restore all CDS copies required to support the current recovery technique. If the recovery technique update in the following step requires new CDS copies, then include them in this restore.
Run the SET utility with the appropriate recovery technique value. It is important to note that the SET utility for this recovery technique update must include DD statements for all CDS copies defined in either the old or the new recovery technique.
Run the BACKup utility again. This backup provides you with the ability to restore the updated CDS.

SET VAULT

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

SET VAULTVOL

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET VAULTVOL command defines the VAULT volume area. This information is stored in the CDS and serves the VAULT volume area information source for all server systems that access the CDS.

Note:

You must run this utility before running the SET VAULT utility.
There is no SET utility command to increase, decrease, or remove all vault volume records once the SET VAULTVOL utility is run. To increase the number of vault volume records, use the Merge CDS utility to migrate vaults and vaulted volumes to a CDS that has been configured with a greater number of vault volumes.

Syntax

Figure 3-161 shows SET VAULTVOL command syntax.

Figure 3-161 SET VAULTVOL command syntax

Surrounding text describes Figure 3-161 .

Parameters

As shown in Figure 3-161, the SET VAULTVOL command includes the following parameters:

NBRVOLS(nnnnnn)

specifies the number of VAULT volumes to be added to the CDS.

nnnnnn indicates the number of volumes. This number can be 1-9,999,999,999.

Note:

Refer to Oracle's ELS publication Configuring HSC and VTCS for details on calculating CDS space requirements for Vaulting.
The number of Vault volumes must be greater than the total number of slots for all Vaults created with the SET VAULT utility.

SET VOLPARM

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET VOLPARM command defines the volume and pool information for a server complex. This information is stored in the CDS and is the volume and pool information source for all server systems (ELS 7.0 or higher) that access the CDS.

SET VOLPARM reads POOLPARM and VOLPARM control statements that define VOLUME/POOL information in the form of named pools of specific types, and their associated volser ranges.

Once SET VOLPARM is run, older volume and pool definitions are disabled for all server systems (ELS 7.0 or higher) that access the common CDS.

Note:

HSC 6.2 or lower systems are unaware of the presence of the SET VOLPARM data and continue to operate as though the SET VOLPARM utility had not been run.
Specify REGION=0M on the EXEC PGM=SLUADMIN statement when the number of input statements exceeds 10,000 card images.
If you delete MVCs or VTVs from the configuration as a result of either SET VOLPARM or CONFIG MVCVOL or CONFIG VTVVOL processing:

If MVCs were deleted, you cannot re-enter the volsers into the configuration as VTVs.

If VTVs were deleted, you cannot re-enter the volsers into the configuration as MVCs.

Do not use the volsers for native HSC tapes.

Message SLS6944I indicates the number of MVCs or VTVs that have been deleted.

The following commands are disabled for systems (ELS 7.0 or higher) after SET VOLPARM:

HSC:

VOLDEF
SCRPDEF

VTCS:

MVCDEF
CONFIG VTVVOL or CONFIG MVCVOL

The HSC/VTCS systems do not need to be recycled for the new volume and pool definitions to take effect. The attached HSC/VTCS in the CDS complex are notified of the definition changes and the volume and pool definitions are automatically active.

Syntax

Figure 3-162 shows SET VOLPARM command syntax.

Figure 3-162 SET VOLPARM command syntax

Surrounding text describes Figure 3-162 .

Parameters

As shown in Figure 3-162, the SET VOLPARM command includes the following parameters:

APPLY

specifies whether the POOLPARM or VOLPARM definitions are to be applied to the CDS:

NO: Validate the definitions but do not apply them to the CDS (the default).
YES: Apply the definitions. If you specify YES, the SLSPARM data set containing POOLPARM and VOLPARM control statements is read and applied to the CDS. Additionally, the date and time of this action is stored in the CDS, and is output by the Display CDS command.

POOLPARM and VOLPARM control statements are defined in the SLSPARM data set, and define VOLUME or POOL information in the form of named pools of specific types, and their associated volser ranges.

When a POOLPARM statement is read, all subsequent VOLPARMs encountered until the next POOLPARM statement are applied to the prior POOLPARM.
When VOLPARM statements are read without a prior POOLPARM, those VOLSER volumes will be considered non sub-pool (subpool 0) volumes.

See "POOLPARM Control Statement" and "VOLPARM Control Statement" for more information.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statement applies to the SET VOLPARM JCL:

SLSPARM: specifies the data set that contains the POOLPARM and VOLPARM control statements that define volumes and pools.

Using SET VOLPARM to Disable POOLPARM/VOLPARM

To disable POOLPARM or VOLPARM, run the SET VOLPARM utility with an empty SLSPARM input file.

Once POOLPARM or VOLPARM is disabled:

The previous version of POOLPARM or VOLPARM remains in effect for MVC and VTV definitions until you run VTCS CONFIg.
The previous POOLPARM or VOLPARM POOL definitions remain in effect until you run the VOLDEF, SCRPDEF and MVCDEF commands on the HSC host(s).

POOLPARM Control Statement

POOLPARM control statements define pool information for a server complex in the form of named pools of specific types.

VOLPARM statements define a volser, volser list, or volser range to be associated with the specified POOLPARM statement.

POOLPARM and VOLPARM statements are defined in the SLSPARM data set, and are loaded using the SET VOLPARM utility. See "SET VOLPARM" for more information.

When a POOLPARM statement is read, all subsequent VOLPARM statements encountered before the next POOLPARM statement are applied.
When VOLPARM statements are read without a prior POOLPARM, those VOLSER volumes are considered non-subpool (subpool 0) volumes.

Syntax

Figure 3-163 shows POOLPARM control statement syntax.

Figure 3-163 POOLPARM control Statement syntax

Surrounding text describes Figure 3-163 .

Parameters

As shown in Figure 3-163, the POOLPARM control statement includes the following parameters:

TYPE: specifies the type of pool definition. Valid types include SCRATCH, CLEAN, MVC, and EXTERNAL.

TYPE(SCRATCH) Subparameters

If you specify TYPE(SCRATCH), the following subparameters apply:

NAME(nnnn)

specifies the name of the volume pool.

NAME is required for TYPE(SCRATCH) pools. Additonally, NAME(DEFAULTPOOL) is not valid for TYPE(SCRATCH) pools.

nnnn indicates the volume pool name. A maximum of 13 characters is allowed. Blank spaces are not allowed.

HOSTid(host-id)

optionally, defines the hosts that can access the named sub-pool.

host-id indicates the host id. Multiple host-ids may be specified, separating each host-id value with a comma. If a host-id is not specified, the default is all hosts.

HOSTid determines which client hosts can mount volumes from the named subpool. If a mount request is received from a client not specified in the HOSTid list, the HSC rejects the mount request and the mount is not satisfied. If you did not specify an ALIASHOST on the SMC SERVer command, then specify the 4 character SMFID of the MVS hosts that will access the subpool. Otherwise, you can specify up to 8 characters for the host name matching the SMC ALIASHOST specification.

LABEL

optionally, specifies the label type associated with the named subpool. Specify one of the following:

SL indicates standardlabeled tape. This is the default if the parameter is omitted.
AL indicates ANSIlabeled tape.
NL indicates nonlabeled tape.
NSL indicates nonstandard labeled tape.

Note:

Scratch volume requests without a sub-pool (sub-pool 0) will come from volumes not defined in named subpools.

DRTEST

optionally, specifies that the scratch pool is to be used in DRTEST environments.

TYPE(CLEAN) Subparameters

If you specify TYPE(CLEAN), the following subparameters apply:

MAXclean

optionally, specifies the maximum cleaning cartridge usage for the named sub-pool. Do not specify values that exceed the manufacturer's recommendation for usage.

The volumes defined in the CLEAN sub-pools must begin with the cleaning cartridge prefix defined in the LIBGEN.

Note:

If MAXclean is not specified in the VOLPARM statement, the value or default of the MAXclean parameter in the MNTD operator command is used for all cleaning cartridge counts.

TYPE(MVC) Subparameters

If you specify TYPE(MVC), the following subparameters apply:

NAME(nnnn)

specifies the name of the volume pool. This parameter is optional for TYPE(MVC) pools. Additionally, NAME(DEFAULTPOOL) is not valid for TYPE(MVC). NAME(ALL) is not valid for TYPE(MVC) pools.

nnnn indicates the volume pool name. A maximum of 13 characters is allowed. Blank spaces are not allowed.

DRTEST

optionally, specifies that the MVC pool is to be used only in DRTEST environments.

INITMVC

optionally, enables or disables the MVC initialization feature.

YES: enables the MVC initialization feature.
NO: disables the MVC initialization feature.

MVCFREE(nn)

optionally, specifies the minimum number of free MVCs in the MVC pool. A free MVC has 100% usable space and does not contain any migrated VTVs.

nn indicates the number of MVCs. Valid values are 0 to 255. There is no default; if not specified, the CONFIG RECLAIM value (or default) is used.

If free MVCs is equal or less than this value, VTCS issues message SLS6616I and initiates an automatic space reclamation.

MAXMVC(nn)

optionally, specifies the maximum number of MVCs to be processed in a single space reclamation run.

nn indicates the number of MVCs. Valid values are 1 to 98. There is no default; if not specified, the CONFIG RECLAIM value (or default) is used.

For automatic space reclamation to start, the number of eligible MVCs (determined by the THRESH parameter) must also exceed the MAXMVC value.

START=nn

optionally, specifies the level at which automatic space reclamation starts for each ACS (not globally for all ACSs), or, if specified, for a Named MVC Pool.

nn is a percentage value, which is equal to:

Reclaim Candidates / (Reclaim Candidates + Free MVCs) * 100

Where:

Reclaim Candidates indicates the number of Reclaim Candidates determined by the CONFIG RECLAIM THRESHLD parameter.
Reclaim Candidates + Free MVCs equals the number of Reclaim Candidates plus the number of free MVCs.

Valid values are 1 to 98. There is no default. If not specified, the CONFIG RECLAIM value (or default) is used.

THRESH(nn)

optionally, specifies the percentage of fragmented space that makes an MVC eligible for demand or automatic reclamation.

nn indicates the percentage. Valid values are 4 to 98. There is no default; if not specified, the CONFIG RECLAIM value (or default) is used.

INPTHRSH(nn)

optionally, specifies the percentage of fragmented space that makes an MVC in partitioned format (within the pool) eligible for dynamic reclaim processing.

This value overrides the global INPTHRSH value specified in the CONFIg RECLAIM statement. If this parameter is not specified, the current active global INPTHRSH value is used.

nn indicates a percentage between 3 and 97. This value must be less than the THRESHLD value.

Note:

RECLaim

optionally, specifies space reclaim behavior of the MVCPOOL.

AUTo

VTCS will output message SLS6699E and schedule automatic space reclaims. Reclaims may also be invoked using the RECLAIM command. This is the default.

DEMand

VTCS will not output message SLS6699E and will not schedule automatic space reclaims. Reclaims may be invoked using the RECLAIM command.

RECLaim(DEMand) is mutually exclusive with MVCFREE and START.

REPortonly

VTCS will output message SLS6699E but will not schedule automatic space reclaims. Reclaims may not be invoked using the RECLAIM command.

RECLaim(REPortonly) is mutually exclusive with MAXMVC, START, and THRESH.

Note:

REPortonly is equivalent to, and replaces, the NORECLAM parameter though NORECLAM is still tolerated if the RECLaim parameter is not specified.

NONe

VTCS will not output message SLS6699E and will not schedule automatic space reclaims. Reclaims may not be invoked using the RECLAIM command.

RECLaim(NONe) is mutually exclusive with MVCFREE, MAXMVC, START, and THRESH.

NORECLAM

optionally, specifies that the named MVCPOOL will not be eligible for space reclamation.

Note:

The use of the MVCFREE, MAXMVC, THRESH, INPTHR and START parameters override the values specified on CONFIG for the named sub-pool.

NOMIGRAT

optionally, specifies that the MVCPOOL will not be eligible for selection for migration MVCs This enables MVC information to be retained in the CDS virtual area. The MVCs will not be used for new migrations.

TYPE(EXTERNAL) Subparameters

If you specify TYPE(EXTERNAL), the following subparameters apply:

NAME(nnnn)

specifies the name of the volume pool. This parameter is required for TYPE(EXTERNAL) pools.

nnnn indicates the volume pool name. A maximum of 13 characters is allowed. Blank spaces are not allowed.

OWNRPLEX

optionally, specifies the name of the TapePlex that owns the volumes in the external pool.

For VTVs, this controls volumes imported via Cross-TapePlex Replication. A VTV can only be imported if the sending system's TapePlex name matches the OWNRPLEX value.

Volumes in an EXTERNAL pool can be scratched only if the scratch request originates from the TapePlex matching the OWNRPLEX name. The TapePlex name is defined via the SMC TAPEPLEX NAME parameter and the CONFIG TAPEPLEX THISPLEX parameter.

Alternatively, volumes in an external pool with an OWNRPLEX name of LOCALHSC can be scratched on the local system (but not used as scratch volumes on the local system).

Note:

Refer to Oracle's ELS publications Managing HSC and VTCS and ELS Disaster Recovery and Offsite Data Management Guide for more information about Cross-TapePlex Replication.

VOLPARM Control Statement

VOLPARM control statements define volume attributes for a server complex. These statements define a volser, volser list, or volser range to be associated with a specified POOLPARM statement.

POOLPARM and VOLPARM statements are defined in the SLSPARM data set, and are loaded using the SET VOLPARM utility. See "SET VOLPARM" for more information.

VOLPARM statements follow a POOLPARM statement and apply only to that POOLPARM.

When a POOLPARM statement is read, all subsequent VOLPARM statements encountered before the next POOLPARM statement are applied.
When VOLPARM statements are read without a prior POOLPARM, those VOLSER volumes are considered non-subpool volumes.

Syntax

Figure 3-164 shows VOLPARM control statement syntax.

Figure 3-164 VOLPARM Control Statement syntax

Surrounding text describes Figure 3-164 .

Parameters

As shown in Figure 3-164, the VOLPARM control statement includes the following parameters:

VOLSER(volser, vol-range, or vol-list)

specifies one or more volumes to which this definition applies.

volser, volrange, or vollist indicates a single VOLSER, a VOLSER range, or a list of VOLSERs.

Do not overlap the ranges. Doing so causes an error which invalidates the entire POOLPARM definition.

MEDia(media-type)

optionally, specifies the media type for the volume(s) specified on the VOLSER parameter.

media-type indicates the media type.

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

Note the following:

Only specific media types can be entered. Generic media types, that is, LONGItud and HELical cannot be specified.
If this parameter is not specified, a default is chosen based on the value of the RECtech parameter. Table A-2 shows default values used if MEDia is omitted.
If both media type and recording technique are omitted, all media types and recording techniques are assumed to be eligible. It is recommended that MEDia always be specified on all VOLPARM statements.

RECtech(recording-technique)

optionally, specifies the method used to record data on the media for the volume(s) specified on the VOLSER parameter.

recording-technique indicates the recording technique.

See Appendix A, "MEDia, RECtech, and MODel Values" for valid recording-technique values.

If this parameter is not specified on any matching VOLPARM statement, a default is chosen based on the value of the MEDia parameter. Table A-4 shows default values used if RECtech is omitted.

INITSCR

optionally, specifies that the VIRTUAL volume has an initial status of SCRATCH.

The INITSCR parameter is only valid with MEDIA(VIRTUAL) and/or RECTECH(VIRTUAL) volumes. INITSCR only has meaning when the VTV is first defined.

DRTEST

optionally, specifies that the volumes in the defined range are to be used only in DRTEST environments. The DRTEST parameter is only valid for VOLPARM statements defined before the first POOLPARM statement.

SET VOLPARM UPDATE

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The SET VOLPARM UPDATE command defines the changes to the volume and pool information for a server complex. The information stored in the CDS by the SET VOLPARM utility is changed to reflect the new VOLUME or POOL information.

The HSC/VTCS systems do not need to be recycled for the updated volume pool definitions to take effect. The attached HSC/VTCS in the CDS complex are notified of the definition changes and the volume and pool definitions are automatically active.

Syntax

Figure 3-165 shows SET VOLPARM UPDATE command syntax.

Figure 3-165 SET VOLPARM UPDATE command syntax

Surrounding text describes Figure 3-165 .

Parameters

As shown in Figure 3-165, the SET VOLPARM UPDATE command includes the following parameters:

APPLY

specifies whether the POOLPARM or VOLPARM changes are to be applied to the CDS:

NO: Validate the changes but do not apply them to the CDS (the default).
YES: Apply the changes. If you specify YES, the SLSPARM data set containing the POOLPARM and VOLPARM change control statements is read and applied to the CDS.

POOLPARM and VOLPARM change control statements are defined in the SLSPARM data set and define VOLUME or POOL information in the form of named pools of specific types, and their associated volser ranges.

When a POOLPARM statement is read, all subsequent VOLPARM statements encountered until the next POOLPARM statement are applied to the prior POOLPARM.
When VOLPARM statements are read without a prior POOLPARM, those VOLSER volumes will be considered non-subpool (subpool 0) volumes.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statement applies to the SET VOLPARM UPDATE JCL:

SLSPARM: specifies the data set that contains the POOLPARM and VOLPARM change control statements that define the pool and volume changes to the CDS volume and pool information.

POOLPARM Change Control Statement

POOLPARM Change control statements define new pool information for a server complex in the form of named pools of specific types.

VOLPARM Change control statements define or remove a volser, volser list, or volser range associated with the specified POOLPARM Change statement.

POOLPARM and VOLPARM Change statements are defined in the SLSPARM data set, and are loaded using the SET VOLPARM UPDATE utility. See "SET VOLPARM" for more information.

When a POOLPARM Change statement is read, all subsequent VOLPARM Change statements encountered before the next POOLPARM Change statement are applied.
When VOLPARM Change statements are read without a prior POOLPARM, those VOLSER volumes are considered non-subpool (subpool 0) volumes.

Syntax

Surrounding text describes Figure 3-166 .

Parameters

As shown in Figure 3-166, the POOLPARM Change control statement includes the following parameters:

change-type

specify one of the following to add, delete, or update a pool:

ADD: A new pool is to be added to the server complex. VOLPARM change statements that follow this POOLPARM change statement will define the volumes associated with this pool.
DELETE: An existing pool is to be deleted. When the pool is deleted, the associated volumes will also be deleted.
UPDATE: An existing pool definition is to be changed. UPDATE can be used to change POOLPARM parameters. For example, the value of the MVCFREE parameter may be changed. UPDATE is also used to associate the VOLPARM change statements that follow with the correct pool.

Note:
UPDATE cannot be used to change the name of a pool.

pool-parameters

Syntax

Figure 3-170 shows STOPMN command syntax.

Figure 3-170 STOPMN command syntax

Surrounding text describes Figure 3-170 .

Parameters

As shown in Figure 3-170, the STOPMN command includes the following parameters:

PGMI

specifies that monitoring of cartridge move requests from the programmatic interface is to be terminated.

,L(cc or name)

optionally, identifies the console where the monitoring information is being displayed. If this parameter is omitted or if L= is specified without a console ID or console name, the monitoring being displayed on the console that issued the command is terminated.

cc optionally indicates the console ID. Allowable values are decimal in the range from 00 through 99. Specifying 00 stops information from being sent explicitly to the hardcopy log.

name optionally indicates the console name.

SWitch

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at FULL service level

Description

The SWitch command can be used to manually reverse the roles of the master and standby LMUs or Library Controllers (LCs). The following configurations support switching:

dual LMU
SL8500 dual Library Controller (LC)

In a dual LMU environment, this command initiates an IPL in the master LMU, causing the current standby LMU to become the master LMU. If the former master LMU completes the IPL successfully, it then assumes the role of the standby LMU.

In a dual LC configuration for a multiple SL8500 library ACS, the SWitch command issues a request to the LMU to switch the library LCs by library ID.

Caution:

Issue the Display Acs command before you enter the SWitch command to ensure the library to switch includes an assigned TCP/IP address or host name for the standby. If it does not, do not switch the library because doing so causes the HSC to lose communication with the library.
Before you issue the SWitch command, stop all HSC activity.
After you issue the SWitch command, do not start HSC on any other hosts and do not start any HSC activity (mounts, dismounts, Display ACS, or any other commands) until the switch process is complete.

Note:

For this release, only the SL8500 library is supported for dual LC switching.
For an automatic switch to occur (for example, from LCA to LCB or visa versa), the LC must fail. In this case, if there is a network/communication problem with LCA, the HSC goes into network recovery for the LCA connection(s). If you cannot recover or fix the connection, issue the SWitch command to switch LCA to LCB manually.
Before you issue the SWitch command, if the library is partitioned, be aware of other host software groups (ACSLS, HSC, ELS) using other partitions in the same library.

Syntax

Figure 3-171 shows SWitch command syntax.

Figure 3-171 SWitch command syntax

Surrounding text describes Figure 3-171 .

Parameters

As shown in Figure 3-171, the SWitch command includes the following parameters:

Acs acs-id

optionally, indicates that an ACSid is being specified. This parameter is required for a multipleACS environment configuration or if an acsid is specified.

acsid identifies the ACS that must switch the current active connection as standby and bring the standby connection online as active.

In a single ACS configuration, Acs acsid is optional and defaults to ACS 00. If the acs-id defaults to 00 or is specified with no other parameters, then all of the ACS's active connections are switched to standby, and the standby connections are switched to active.

RESET

Optionally, used in conjunction with ACS acs-id to reset the internal switch setting and internal conflict counts for an ACS. This is helpful when a SWitch is invoked for an SL8500 library and one or more LSMs fail to reach ready state after the SWitch process completes.

Before issuing a SWitch RESET command, it is recommended that you enter the Display Status command to determine which ACS(s) are in the switch process and which ACSs are conflict active.

Verify that the library has completed the SWitch process before you consider issuing a SWitch RESET command. Also verify that a SWitch RESET is complete before you consider issuing another SWitch command.

Use the following guidelines to determine when to issue a SWitch RESET command after a SWitch ACS command is issued:

Issue SWitch RESET after the SWitch process completes, as indicated by the following message:

SLS0694I ACS aa: Switch has completed

If this message is not displayed, wait for the SLS6013I message to be displayed for the active connection before issuing the SWitch RESET command.
If you receive the following message after the switch process has completed:

SLS1004I ACS aa cannot switch; ACS is busy

Issue the SWitch RESET command on another host. If the SLS1004I message is displayed again, bring up another HSC host and issue the SWitch RESET command, or restart an HSC host and then issue the SWitch RESET command.

LIBrary lib-id

optionally, specifies the SL8500 library ID for the connection switch. This parameter applies only to the SL8500 library.

lib-id indicates the library id from 1 to 9 or A to G.

For an SL8500 four library ACS cluster, each library is assigned an ID from 1 to 4, as shown in the following figure:

Figure 3-172 SL8500 Cluster Library IDs

Surrounding text describes Figure 3-172 .

An ACS can have up to 16 library connections with A and B Library Controller (LC) connections. For the initial release, only one library (preferred to be ID 1) can have A and B LC connections. The other libraries can have a single LC connection. Each LC can handle dual TCP/IP (2B and 2A). The following table describes the LSM ID correlation to Library ID:

Table 3-16 LSM ID and Library ID

Library ID	LSM ID Range
1	00-03
2	04-07
3	08-0B
4	0C-0F
5	10-13
6	14-17
7	18-1B
8	1C-1F
9	20-23
A	24-27
B	28-2B
C	2C-2F
D	30-33
E	34-37
F	38-3B
G	3C-3F

Note:

Before issuing this command, use the Display ACS acs-id command to see if the library to switch has a TCP/IP address or Host Name assigned to the standby. If there is not a TCP/IP address or Host Name assigned to the standby, do not switch the library as this will cause HSC to lose communication to the library.
For a switch to occur (for example, from LCA to LCB), the LC must fail. For example, if there is a network/communication problem with LCA, HSC enters network recovery for the LCA connection(s). If you cannot recover/fix the connection, then issue the HSC SWitch command to manually switch LCA to LCB.
If the library is partitioned, please be aware of the other host software groups (ACSLS, HSC, ELS) that are using other partitions in the same library before issuing the SWitch command.

UEXIT

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The UEXIT command defines how HSC processes your user exits.

HSC user exits allow you to invoke your own processing routines at particular points during HSC processing. User exits controlled by the HSC are loaded at HSC initialization from the load library identified by DDNAME SLSUEXIT. The following user exits are managed by the HSC using the UEXIT command:

SLSUX03
SLSUX05
SLSUX06
SLSUX14
SLSUX15

Using the UEXIT command, you can start the HSC with a user exit disabled and then enable the exit at any time the HSC is operational. If an exit does not perform as expected, make the necessary changes and load it again.

The UEXIT command optionally enables you to provide unique user exit load module names and to create different versions of an exit that can be run at different times (for example, day shift versus night shift). The load modules are contained in a user-defined load module library described at HSC startup.

Note:

User Exit 03 and User Exit 05 are legacy interfaces and have been replaced by alternative facilities that do not require a User Exit.
User Exit 03 is enabled at HSC initialization. The UEXIT command cannot be used to enable, disable, or reload this exit.

Syntax

Figure 3-175 shows UEXIT command syntax.

Figure 3-175 UEXIT command syntax

Surrounding text describes Figure 3-175 .

Parameters

As shown in Figure 3-175, the UEXIT command includes the following parameters:

nn

specifies the user exit number. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for user exit numbers.

Load

causes the specified module to be loaded into storage.

SLSUXnn: specifies the default name for the user exit. If name is not specified, then the default name is used when the HSC loads the module into storage.
name: the name of the module to be used for this exit. This is the entry point name which is used to linkedit the load module.
Enable: indicates that upon completion of the command the specified exit is considered as being active. Enable is the default.
Disable: indicates that upon completion of the command the specified exit is considered as being inactive.

Enable

optionally, specifies that the most current module for the specified user exit (nn) is to be enabled. This parameter may also be specified with the Load parameter.

Disable

optionally, specifies that the most current module for the specified user exit (nn) is to be disabled. This parameter may also be specified with the Load parameter.

nn, nn-range, or nn-list

can be used with the Query parameter to specify a single user exit, a range of exits, or a list of exits.When specifying a range of user exit numbers, the beginning number must be separated from the ending number by a hyphen. For example: (0409) In a list of user exits, the user exit numbers must be separated by commas and the list must be enclosed in parentheses. For example: (01,04,10)

Query

requests the status of all the currently loaded versions of the specified user exit number(s). A display of user exit status may be specified for a single user exit, a range of exits, or a list of exits.

UNSElect

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The UNSElect command unselects a volume that is erroneously in a selected state.

Note:

Use this utility only if you are certain that the HSC has incorrectly left the volume selected. Incorrect use of this utility can result in HSC abends and errant volumes.

Issue a Display Volume DEtail command to determine which host has the volume in question. Then, issue Display DRives and Display Requests commands on the host that has the volume in question to see if that volume is being used.

If the selected volume is mounted on a transport, issue a DISMount command for the transport. If there is a request active to the LMU for the volume, wait for the request to complete. If the overdue response handler indicates the request has timed out, you may want to abort the request.
The UNSElect function can only be invoked when SLUADMIN is invoked APF authorized, key 0 through 7, or supervisor state. The load module invoked by UNSElect is SLUNSEL. Restricting access to this module restricts access to this utility function.

Syntax

Syntax

Figure 3-179 shows VIew command syntax.

Figure 3-179 VIew command syntax

Surrounding text describes Figure 3-179 .

Parameters

As shown in Figure 3-179, the VIew command includes the following parameters:

CAp

indicates that a camera is to focus on a cell location in a CAP. If you do not specify the CAPID or Lsm parameter, the command defaults to CAPid 00:00:00. If you do not specify the Row and Column parameters, the command defaults to row 0, column 0.

CAPID(cap-id)

identifies one CAP in an LSM that contains multiple CAPs.

capid indicates the CAP that you want to view. The format of a capid is AA:LL:CC, where AA:LL indicates the LSMid, and CC indicates the CAP. See "CAPid" for a list of valid values.

Lsm(lsm-id)

identifies an LSM that contains a single CAP.

lsmid indicates the single CAP that you want to view. The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

Row(rr)

identifies a row number in a CAP. If you do not specify this parameter the command defaults to row 0.

rr indicates the row number. Allowable values for rr are decimal and are specific to the LSM type. See "Rows" for a list of valid values.

Column(cc)

identifies the column number within a CAP. If you do not specify this parameter the command defaults to column 0.

cc indicates the column number. Allowable values for cc are decimal and are specific to the LSM type. Columns are numbered starting at the left of the panel. See "Columns" for a list of valid values.

CEll

indicates that a camera is to focus on a cartridge storage or diagnostic cell in an LSM panel. If you do not specify the Lsm, Panel, Row, and Column parameters, the command defaults to LSM 00:00, panel 0, row 0, column 0.

Lsm(lsm-id)

identifies an LSM. If you do not specify this parameter, the command defaults to LSMid 00:00.

lsmid indicates the LSMid. The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

Panel(pp)

designates the LSM panel number containing the cartridge storage or diagnostic cell that the camera is to view. If you do not specify this parameter the command defaults to panel 0.

pp indicates the panel number. Allowable values for pp are decimal and are specific to the LSM type. See "Panels" for a list of valid values.

Row(rr)

identifies a row number in an LSM panel. If you do not specify this parameter the command defaults to row 0.

Column 3 on panel 2 allows row entries only on rows 28-41. The cells on panel 3 are optional.

Column(cc)

identifies the column number within a panel. If you do not specify this parameter the command defaults to column 0.

DRive

indicates that a camera is to focus on a cartridge drive. You must designate the Address parameter to identify the drive. The Host parameter enables you to view a drive defined to another host.

Address(xxx)

specifies the address of a cartridge drive. The Address parameter defines the operating system address of the transport you want to inspect.

xxx indicates the hexadecimal address of the transport. The HSC verifies that the specified address matches the LIBGENdefined address for the given host.

Host(host-id)

gives meaning to the Address parameter when the drive being inspected is not defined in the LIBGEN for the host from which the VIew command is being entered.

If you do not specify the Host parameter, the HSC checks the LIBGENdefined drive list for the host from which you entered the VIew command. If the address is found in the drive list, the command is executed.

hostid indicates the host where the transport is defined.

PLaygrnd

indicates that a camera is to focus on a playground cell. If the Lsm and Column parameters are not specified, the command defaults to the relative location of the cell in the playground in LSM 00:00.

Note:

The playground is a reserved area of cells where the robot deposits cartridges that it finds in its hands during LSM initialization. Normal LSM initialization recovery processing moves cartridges from the playground cells to either their home cells or their intended destinations, but under abnormal circumstances cartridges may be left in playground cells. Refer to the appropriate Oracle StorageTek hardware publication for the location of the playground in the LSM.

Lsm(lsm-id)

identifies an LSM. If you do not specify this parameter, the command defaults to LSMid 00:00.

lsmid indicates the LSMid. The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

Column(cc)

identifies the relative location of the cell in the playground for a panel. If you do not specify this parameter, the command defaults to the relative location of the cell in the playground.

cc indicates the relative location of the cell in the playground. Allowable values for cc are decimal and are specific to the LSM type. (Some LSMs have multiple playground cells and some have only one.)

PTp

indicates that a camera is to focus on a passthru port (PTP) cell. You can designate a particular PTP using the Lsm and Xlsm parameters, a particular cell using the Column parameter, and specify the viewing time using the Time parameter.

Note:

When the PTP is being shared by two different LSM types, the upper limit of the column value is determined by the LSM with the smaller PTP capacity.

Lsm(lsm-id)

identifies an LSM. If you do not specify this parameter, the command defaults to LSMid 00:00.

lsmid indicates the LSMid. The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).

Xlsm(ll)

identifies the PTP to be inspected by defining the LSM that shares the PTP.

Each PTP is identified by the two LSMs it services. The Lsm parameter identifies which robot is used to view the PTP, and the Xlsm parameter identifies the LSM that shares the PTP. This distinction is necessary whenever an LSM contains more than one PTP.

If Xlsm is not specified for an LSM containing two or more PTPs, the HSC examines the LIBGEN and selects the first PTP defined there for Lsm(lsmid).

ll indicates the LSM number of the adjacent LSM. Values for ll are decimal in the range from 00-99. (The ACS is identified in the Lsm parameter.)

Column(c)

identifies the column number within a panel. If you do not specify this parameter the command defaults to column 0.

c indicates the column number. Allowable values for c are decimal and are specific to the LSM type:

0-3 for LSM Models 4410, 9310, and 9740
0 or 1 for WolfCreek LSMs (all models).

Note:

When the PTP is being shared by two different LSM types, the upper limit of the column value is determined by the LSM with the smaller PTP capacity.

Time(ttt)

specifies the video monitor viewing time.

ttt indicates the time, in seconds.

VLEMAINT

Interfaces:

Console or utility
UUI Support: Yes

Subsystem Requirements:

Active HSC/VTCS

Description

The VLEMAINT utility command moves or copies VLE based MVC (VMVC) data content to a specified VLE system, without using VTSS storage resources.

This utility should only be used under the guidance of Oracle Support personnel.

Syntax

Figure 3-180 shows VLEMAINT command syntax.

Figure 3-180 VLEMAINT command syntax

Surrounding text describes Figure 3-180 .

Parameters

As shown in Figure 3-180, the VLEMAINT command includes the following parameters:

MOVEMVC(mvc-list or mvc-range)

specifies a list or range of VLE based MVCs whose content is to be moved to the specified target VLE system. MVCs selected in the target VLE system inherit the storage class of the source MVC.

mvc-list or mvc-range indicates the list or range of MVCs.

MOVEMVC is mutually exclusive with COPYMVC.

TOVLE(name)

specifies the target VLE to receive the source VMVC data. This parameter is required.

name indicates the target VLE name. This VLE must be valid (defined to the configuration). Otherwise, the utility aborts with a return code 8.

MGMTclas(name)

optionally, specifies a single management class used to filter data sent to the target VLE. Only VTVs with this management class are sent to the target VLE.

name indicates the management class name. This name must be valid (defined in MGMTDEF). Otherwise, the utility aborts with return code 8.

COPYMVC(mvc-list or mvc-range)

specifies a list or range of VLE based MVCs whose content is to be copied to the specified target VLE system. COPYMVC creates an additional copy of the data to another storage class on the target VLE system.

mvc-list or mvc-range indicates the list or range of MVCs.

COPYMVC is mutually exclusive with MOVEMVC. COPYMVC requires a STORclas name to be specified.

TOVLE(name)

specifies the target VLE to receive the source VMVC data. This parameter is required.

name indicates the target VLE name. This VLE must be valid (defined to the configuration). Otherwise, the utility aborts with a return code 8.

STORclas(name)

optionally, specifies the storage class assigned to the VMVC selected at the target VLE for COPYMVC processing. This parameter is required when COPYMVC is specified.

name indicates the storage class name. This name must be valid (defined in MGMTDEF). Otherwise, the utility aborts with a return code 8.

Optional Parameters (VLEMAINT COPYMVC)

If you specify VLEMAINT COPYMVC, the following optional parameters apply:

MGMTclas(name)

optionally, specifies a single management class used to filter data sent to the target VLE. Only VTVs with this management class are sent to the target VLE.

name indicates the management class name. This name must be valid (defined in MGMTDEF). Otherwise, the utility aborts with return code 8.

REPMGMT(name)

optionally, specifies a single management class name assigned to the VTV data after it is received by the target VLE system for COPYMVC processing.

name indicates the management class name. This name must be valid (defined in MGMTDEF). Otherwise, the utility aborts with return code 8.

Note:

During COPYMVC processing, any VTV found with the management class specified in REPMGMT is bypassed. This could potentially serve as a copy complete acknowledgment if utility restarts occur.

VOLPCONV

Interfaces:

SLUADMIN utility only
UUI Support: No

Subsystem Requirements:

Active HSC not required

Description

The VOLPCONV command reads existing VOLDEF, SCRPDEF, MVCDEF, and VTCS CONFIG input statements and converts them to SET VOLPARM statements. The existing VTCS configuration is also input to the utility.

Syntax

Figure 3-181 shows VOLPCONV command syntax.

Figure 3-181 VOLPCONV command syntax

Surrounding text describes Figure 3-181 .

Parameters

As shown in Figure 3-181, the VOLPCONV command includes the following parameters:

CLNPRFX(prefix or CLN)

specifies a prefix to apply to all types of cleaning cartridges.

prefix indicates a three-character prefix. CLN is the default.

Additional JCL Requirements

In addition to the required JCL definition statements described in "Invoking SLUADMIN", the following definition statements apply to the VOLPCONV JCL:

SLSVOLA: input VOLDEF definitions in the form of VOLATTR statements.

Note:
VOLATTR statements coded with the masking character (%, ? or *) within the SERIAL parameter are not supported and will cause message SLS0227I to be issued. Any VOLATTR statement using these masking characters must be converted to a range that spans the intent of the masking characters prior to running VOLPCONV.
SLSSCRP: input SCRPDEF definitions in the form of SCRPOOL statements.
SLSMVCP: input MVCDEF definitions in the form of MVCPOOL statements.
SLSVTCS: input VTCS configuration definitions. The VTCS configuration definitions can be obtained by running the VTCS DEComp utility.
SLSPARM: output VOLUME or POOL definitions in the form of POOLPARM and VOLPARM control statements. The logical record size of the SLSPARM data set is 80.

VOLRpt

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required

Description

The VOLRpt command produces a volume report.

Syntax

Figure 3-182 shows VOLRpt command syntax.

Figure 3-182 VOLRpt command syntax

Surrounding text describes Figure 3-182 .

Parameters

As shown in Figure 3-182, the VOLRpt command includes the following parameters:

ACS(acs-id)

optionally, specifies that a report is to be produced for only a particular ACS.

acsid indicates the one or two digit decimal ACS identifier.

LSM(lsm-list)

optionally, specifies that a report is to be produced for only certain LSMs within an ACS.

lsmlist indicates the LSMs. An lsmlist can be a single LSM number or a list of LSM numbers. An LSM number is decimal 00-99.

An LSM range is not allowed. If a list is specified, the elements must be separated by blanks or commas, and the entire list enclosed in parentheses.

VOLser or VOLume(volser, vol-range, or vol-list)

optionally, specifies that the report only contain information on certain VOLSERs.

volser, volrange, or vollist indicates the volume serial numbers requested. Any subranges of volumes specified in the vollist that are not in the control data set are listed in the Control Card Image Listing portion of the report using one line per subrange.

A percent sign (&rsquor;&rsquor;%'') may be used as a &rsquor;&rsquor;wildcard'' character in the VOLSER to specify pattern matching. The percent sign designates that any single character can match the corresponding position in the VOLSER.

For example, A9%%%% specifies that all of the sixcharacter volume serial numbers that begin with the characters &rsquor;&rsquor;A9'' are selected for the report.

Q%12% specifies that all fivecharacter VOLSERs that begin with &rsquor;&rsquor;Q'' and have a &rsquor;&rsquor;12'' in the third and fourth positions of the VOLSER are selected for the report. The percent sign cannot be specified in a range specification. Therefore, &rsquor;&rsquor;A%0000A%9999'' is invalid.

In the Volume Report Listing of the utility, the volumes requested which are not in the control data set are not listed.

SORT

optionally specifies a specified sort sequence.

Multiple sort criteria may be specified. The order, from left to right, specifies the order in which the report is to be sorted.

For example, SORT(INS,USE) produces a report sorted by date inserted in the control data set, and then for each date, sorted by select count.

Note:

SORT and NOSORT are mutually exclusive.

The following SORT options are available:

VOL

indicates that the report is to be sorted by volume serial number (VOL is the default).

INS

indicates that the report is to be sorted by date and time the volume was inserted into the control data set.

LOC

indicates that the report is to be sorted by location.

SEL

indicates that the report is to be sorted by date and time the volume was last selected.

USE

indicates that the report is to be sorted by selection count.

MWL

indicates that the report is to be sorted by Media Warranty Life (MWL) percentage, which indicates how much of the media life has been used.Media warranty life is considered to be expired at 100%.

To collect and report media warranty life, tape libraries and transports must meet the following requirements:

SL8500 or SL3000 libraries
LMU compatibility level 21 or higher
T9x40: all media and models at firmware level 1.42 or higher (except 9840B)
T10000: all models and media at firmware level 1.38 or higher

Refer to Oracle's ELS publication Managing HSC and VTCS for more information about media warranty life.

ASCend

optionally, specifies that the report is to be sorted in ascending order. ASCend is the default. This parameter is ignored if NOSORT is specified. ASCend is mutually exclusive with NOSORT and DEScend.

DEScend

optionally, specifies that the report is to be sorted in descending order. This parameter is ignored if NOSORT is specified. DEScend is mutually exclusive with NOSORT and ASCend.

NOSORT

specifies that an unsorted report is to be produced. NOSORT is mutually exclusive with SORT, ASCend, and DEScend.

INCLude

optionally, specifies the criteria for including volume information in the report. If this keyword is specified, all volumes that match at least one of the specified criteria are tentatively selected for the report. Information about volumes may be removed from the list of volumes selected for the report if other options, such as EXCLUDE, VOL, ACS, or LSM are specified.

INCLude parameters are applied before EXCLude parameters in volume selection.
Parameter values are not checked for the existence of their opposite values (for example, SEL is still flagged even if NONSEL is specified, and vice versa).
Positive attributes are applied before negative attributes (for example, SCR is applied before NONSCR).

*

indicates that all volumes in the library are considered for being included in the report. The default is *. If more than one of the following parameters is specified, the parameters must be separated by commas.

SCR

specifies that scratch volumes match the specified criteria.

NONSCR

specifies that nonscratch volumes match the specified criteria.

ERR

specifies that errant volumes match the criteria.

NONERR

specifies that nonerrant volumes match the criteria.

SEL

specifies that selected volumes match the criteria.

NONSEL

specifies that nonselected volumes match the criteria.

READable

specifies that volumes with a readable external label match the criteria.

UNREADable

specifies that volumes with an unreadable external label match the criteria.

MEDEQUAL

specifies that volumes for which the media types of the VOLATTR and the VAR are equal match the criteria.

NONMEDEQ

specifies that volumes for which the media types of the VOLATTR and the VAR are not equal match the criteria.

NOEXTernal

specifies that volumes without an external label match the criteria.

For example, INCLUDE(SEL,ERR) tentatively chooses only selected and errant volumes for the report. INCLude parameters are applied before EXCLude parameters in volume selection.

MWLNA

specifies that volumes with an unknown media warranty life match the criteria. Media warranty life is obtained at volume dismount for tape libraries with an LMU compatibility level of 21 or above. Use the Display ACS command to obtain the LMU compatibility level.

MWLGE nnn

specifies that volumes with a media warranty life greater than or equal to nnn percent match the criteria. It also excludes all volumes with an unknown media warranty life.

Specify INCLUDE(MWLNA) to force inclusion of all volumes with an unknown media warranty life. Valid values for nnn are 0-254.

To collect and report media warranty life, tape libraries and transports must meet the following requirements:

SL8500 or SL3000 libraries
LMU compatibility level 21 or higher
T9x40: all media and models at firmware level 1.42 or higher (except 9840B)
T10000: all models and media at firmware level 1.38 or higher

Refer to Oracle's ELS publication Managing HSC and VTCS for more information about media warranty life.

EXCLude

optionally, specifies the criteria for excluding volume information from the report. Any volumes that match one or more of the exclusion criteria are excluded from the report.

EXCLude parameter values are the same as INCLude values, except for the * parameter (see the INCLude options list above).

As an example, EXCL(NONSEL) excludes nonselected volumes from the report.

INCLude parameters are applied before EXCLude parameters in volume selection.
If MWLGE is specified in both the INCLUDE and EXCLUDE parameters, the EXCLUDE limit value must be greater than the INCLUDE limit value.
Parameter values are not checked for the existence of their opposite values (for example, SEL is still flagged even if NONSEL is specified, and vice versa).
Positive attributes are applied before negative attributes (for example, SCR is applied before NONSCR).

*

indicates that all volumes in the library are considered for being included in the report. The default is *. If more than one of the following parameters is specified, the parameters must be separated by commas.

SCR

specifies that scratch volumes match the specified criteria.

NONSCR

specifies that nonscratch volumes match the specified criteria.

ERR

specifies that errant volumes match the criteria.

NONERR

specifies that nonerrant volumes match the criteria.

SEL

specifies that selected volumes match the criteria.

NONSEL

specifies that nonselected volumes match the criteria.

READable

specifies that volumes with a readable external label match the criteria.

UNREADable

specifies that volumes with an unreadable external label match the criteria.

MEDEQUAL

specifies that volumes for which the media types of the VOLATTR and the VAR are equal match the criteria.

NONMEDEQ

specifies that volumes for which the media types of the VOLATTR and the VAR are not equal match the criteria.

NOEXTernal

specifies that volumes without an external label match the criteria.

For example, INCLUDE(SEL,ERR) tentatively chooses only selected and errant volumes for the report. INCLude parameters are applied before EXCLude parameters in volume selection.

MWLNA

MWLGE nnn

specifies that volumes with a media warranty life greater than or equal to nnn percent match the criteria. It also excludes all volumes with an unknown media warranty life.

Specify INCLUDE(MWLNA) to force inclusion of all volumes with an unknown media warranty life. Valid values for nnn are 0-254.

To collect and report media warranty life, tape libraries and transports must meet the following requirements:

SL8500 or SL3000 libraries
LMU compatibility level 21 or higher
T9x40: all media and models at firmware level 1.42 or higher (except 9840B)
T10000: all models and media at firmware level 1.38 or higher

Refer to Oracle's ELS publication Managing HSC and VTCS for more information about media warranty life.

MAXclean(nnnn)

optionally, specifies the maximum cleaning cartridge usage for the ”over max clean” column. The MAXclean specified for each POOLPARM TYPE(CLEAN) overrides this value.

nnnn indicates the maximum usage value. Valid values are 0-32767.

VAULT

optionally, specifies that vaulted volumes are to be included in the detail volume report. VAULT is mutually exclusive with NOVOL, ACS, and LSM.

If the vault CDS subfile does not exist, this parameter is ignored.

Vaulted volumes are not included in the SUMMARY reports. In the detail report, the cell location for a vaulted volume is identified by the word VAULT and the insertion date/time is the date/time that the volume was inserted into the vault; i.e., ejected from the tape library. Refer to the LCM User's Guide for more information about vaulting.

SUMMary

optionally, specifies that the utility provide totals of volume attributes on an LSM and ACS basis, and/or subpool data on an ACS or LSM basis. Totals are affected by the use of limiting parameters such as ACS (and possibly LSM), VOLser or VOLume, and INCLude and/or EXCLude.

If both TOTal and SUBpool are specified, both reports are provided. The time and date displayed in the header for the Summary Report(s) are the same as the Volume Report Listing header.

TOTal

specifies that totals of scratch, selected, errant, available cells, and external label status types be provided on an LSM, ACS, and library basis in the report.

The totals are listed on a separate listing, on a new page from the Volume Report Listing and the Control Card Listing.

SUBpool

specifies that subpool totals be provided on an LSM, ACS, and library basis in the report.

Subpool information can be provided using the VOLPARM facility. See "VOLPARM Control Statement" for more information about defining VOLPARM information. For alternative methods of specifying subpool information, refer to Oracle's ELS publication ELS Legacy Interfaces Reference.

The totals are listed on a separate listing, on a new page from the Volume Report Listing, the Control Card Listing, and the Volume Report Totals Listing.

If subpools overlap (that is, a volume belongs to more than one subpool), then each volume is reported only within the first subpool in which it occurs, and totals for the other subpools may be inaccurate.

NOVOL

optionally, when used with SUMMary, specifies to display summary and/or subpool totals without producing volume detail.

NOVOL should not be specified by itself. NOVOL is mutually exclusive with ACS, VOLser, VOLume, SORT, NOSORT, INCLude, EXCLude, MAXclean, and VAULT.

Additional JCL Requirements

If you are not using the VOLPARM facility to define your volume characteristics, refer to Oracle's ELS publication ELS Legacy Interfaces Reference for a description of additional VOLRPT JCL statements that may be required.

Volume Report

The following is an example of a volume report produced by the VOLRpt command issued with the SUMMary(SUBpool) parameter:

Example 3-58 VOLRpt report

Fields

The VOLRpt report includes the following fields:

Volume Serial

the volume serial number

Media

the media type. See Appendix A, "MEDia, RECtech, and MODel Values".

The media field may be immediately preceded by an asterisk * or dash -.

An asterisk * indicates that the media defined by a VOLATTR statement is not compatible with the media label value.
A dash - indicates that the volume has no VOLATTR or VOLPARM defined media value.

Rectech

the recording technique. See Appendix A, "MEDia, RECtech, and MODel Values".

Cell Loc

the cell location field shows cartridge location by ACS (AA), LSM(LL), panel (PA), row (RO), and column (CO).

Err, Scr, Sel

A Y (yes) flag under the Errant, Scratch, or Selected headings indicates that the volume is currently in that status.

A volume in Errant (Err) status shows the volume's home cell in the Cell Loc column.

A Y (yes) flag under the Selected heading indicates that the volume is currently selected, that is, being mounted, dismounted, ejected, or moved. An M flag indicates that the volume is currently mounted. The Selected column on the totals report includes both selected and mounted volumes. The volume's home cell appears in the Cell Loc column.

Ext Lbl

External Label:

R indicates that the volume has a readable external label.
U indicates that the volume has an unreadable external label.
N indicates that the volume has no external label.

Cln Use

Cartridge Usability:

N indicates that the volume is not usable, for example, a spent cleaning cartridge that is not usable because it has exhausted its cleaning surface.
M indicates that a cleaning cartridge has exceeded its maximum usage set by the MAXclean value (as specified by the MNTD MAXclean or VOLATTR MAXclean parameters).

Subpool ID

the subpool ID.

Scratch subpools for volumes are listed if scratch subpool definitions have been provided using VOLPARM control statements.

*NON-VOLPARM* indicates that VOLPARM is in effect, but this volume is not defined in VOLPARM.
DEFAULTPOOL indicates that the volume is defined in VOLPARM with no associated pool.
*MVC* indicates that the volume is reserved for VTCS usage as a migration volume.
*DEFAULT* indicates that the volume is a cleaning cartridge but has not been included in a VOLPARM defined subpool, *DEFAULT* appears.

If VOLPARM is not used, the generated report is the same as in the HSC 6.2 release. Refer to the HSC 6.2 System Programmer's Guide for more information.

Inserted

date and time that the volume was inserted.

Last Used

date and time that the volume was last used

MWL Media Warranty Life

Media Warranty Life (MWL) is a percentage value that is obtained at volume dismount for tape libraries that are at LMU compatibility level 21 or later. If you do not know the compatibility level, enter the HSC Display Acs command to display it. See "Display ACS" for more information.

The MWL percent indicates how much of the media life has been used and is considered to be ”expired” at 100%. Values may range from 0 to 254. If the field is blank, the MWL is unknown.

Total Reports

Two totals reports can be produced:

volume report totals
subpool totals

Volume Report Totals

Total of cartridges with various characteristics are displayed for LSMs, ACSs, and the entire library.

The total selected volumes is the sum of the number of volumes currently selected and the number of volumes currently mounted.

Note:

The free storage cells reported do not include free cells on frozen panels. An LSM with at least one frozen panel is indicated by an asterisk after the free cell count.

Subpool Totals

Totals of cartridges by subpool are produced for LSMs, ACSs, and the entire library.

Note:

A value of Y in the DRTEST column indicates that the pool is defined using the VOLPARM control statement feature with the keyword DRTEST(YES).

VTVMAINT

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required

Description

The VTVMAINT command does the following:

Unlinks VTVs from MVCs,
Sets the VTV Management Class
Logically dismounts specified VTVs in an offline VTSS.
Specifies ownership of a VTV that has been electronically imported
Adds or deletes references to electronic exported copies of VTVs.

Syntax

Figure 3-183 shows VTVMAINT command syntax.

Figure 3-183 VTVMAINT command syntax

Surrounding text describes Figure 3-183 .

Parameters

As shown in Figure 3-183, the VTVMAINT command includes the following parameters:

VTVid(volser, vol-range, or vol-list)

specifies one or more VTVs.

volser, vol-range, or vol-list indicates the volsers of one or more VTVs.

ULINKMVC

optionally, unlink (logically delete) MVC copies of the specified VTVs.

volser indicates the volume serial number of the MVC. If no value is specified, then all MVC copies of the VTVs are deleted.

MGMTclas(mgmtclas-name)

optionally, set the Management Class of the VTVs.

mgmt-class-name indicates the Management Class name that you specified on the MGMTclas control statement. For more information, see "MGMTclas Control Statement".

DISMOUNT VTSSid(name)

optionally, logically dismount the specified VTVs in the specified VTSS.

name indicates the VTSS name.

If migrated copies of the dismounted VTVs exist that an online VTSS can access, you can now use this VTSS to access the VTVs.

Caution:

If the VTV copy mounted in the offline VTSS was modified and not migrated, the MVC copy that you recall to an alternate VTSS is not current! Therefore, Oracle strongly recommends that you do not recall these non-current MVC copies!

When the offline VTSS is ready to be brought back online, it is strongly recommended that you audit the VTSS before running production jobs that use the VTSS. Also ensure that you clear any boxed VTD conditions before issuing the VTSS VARY ONLINE command.

OWNRPLEX(name)

optionally, specifies ownership of a VTV that has been electronically imported.

name indicates the name of the TapePlex that owns the original copy of the VTV. This name must match one of the known TapePlex names in the configuration.

If this name matches that indicated for the THISPLEX parameter on the CONFIg TAPEPlex statement, the electronic importing status is removed.

DELEXpot(name)

optionally, specifies which references to electronic exported copies of the VTVs are removed.

name indicates the name of the TapePlex that is to be removed. If this parameter value is omitted, then all references to electronic export copies are removed.

This parameter merely removes the reference to the external copy of the VTV from the VTV record. It does not cause a contact of the other TapePlex to modify the remote copy in any way. Depending upon the management class definition for the VTV, removing a reference could cause an automatic re-drive of the export at some later time.

ADDEXpot(name)

optionally, specifies the addition of references to the electronic export copy of the VTV.

name indicates the name of the TapePlex that is to be added. This name must match to one of the names that has been specified in the VTCS configuration.

This parameter merely adds the reference to the external copy to the VTV record. It is assumed that the required copy of the VTV will have been physically placed there by some other process. The VTV record can track a maximum of two TapePlex locations.

Note:

The DELEXpot operation executes before the ADDEXpot operation. This makes it possible to replace the exported location information in a single call. For configurations where the electronic export function is not used, it is acceptable to use the ADDEXpot and DELEXpot parameters to add dummy tracking or user information to the VTV. The information in the VTV record is always cleared when the VTV data is updated.

RENVTSS(vtss-name)

optionally, sets the name of the VTSS where the VTV was last mounted to vtss-name.

vtss-name indicates the new VTSS name. This must be the name of an existing VTSS in your configuration.

Note:

To use RENVTSS, the host on which VTVMAINT is run must have access to the owning VTSS.

Return Codes

VTVMAINT includes the following return codes:

0 indicates that all requested updates for the VTV completed successfully.
4 indicates that one requested update for the VTV failed and at lest one other requested update completed successfully.
8 indicates that all requested updates for the VTV failed.

Note:

The final return code for the VTVMAINT job is the largest return code generated by any single VTVs being updated. For example, if 5 VTVs generate a return code 0 and one VTV generates a return code 8, the final return code is 8.

VTVMAINT Report

The following is an example of a VTVMAINT report produced by the following command:

VTVMAINT VTV(X00000-X00002) ULINKMVC MGMTCLAS(M1)

Surrounding text describes Figure 3-184 .

Parameters

As shown in Figure 3-184, the VTVRPt BASIC command includes the following parameters:

VTVid(volser, vol-range, or vol-list)

optionally, specifies the VTVs for the report. If you do not specify the VTVs, the report includes all initialized VTVs in your VSM system. A VTV is initialized when VTCS has used it at least once.

volser, vol-range, or vol-list indicates the volsers of one or more VTVs.

ALL

optionally, specifies to report on all VTVs (including non-initialized volumes). If you do not specify ALL, only initialized VTVs are reported.

OPTION(UNAVAIL)

optionally, specifies to report only on unavailable VTVs (VTVs in an offline VTSS). The report lists only unavailable VTVs in three sections: unavailable mounted on a VTD, unavailable VTSS-resident, and unavailable VTSS-resident and fenced.

SUPEMPTY

optionally, suppress the printing of empty VTVs.

The VTV report will not print details of VTVs that contain no data or VTVs that are fenced. SUPEMPTY is mutually exclusive with ALL and OPTION(UNAVAIL).

MANIFEST(ddname)

optionally, specifies the input DD name of the manifest file used to generate the report.

ddname indicates the DD name of the manifest file. Note that you can specify a merged manifest file or multiple manifest files. MANIFEST is mutually exclusive with SINCE.

SINCE(nnnn)

optionally, specifies a time in minutes. Only VTVs that have been accessed within the specified time are processed.

nnnn indicates the time in minutes, from 1 to 9999. SINCE is mutually exclusive with MANIFEST.

VTV Report (Basic)

The following is an example of a VTV report produced by the VTVRPt BASIC command:

Fields

The following list describes the fields for the report generated by a VTVRPt or VTVRPt BASIC command:

VTV Volser

the VTV volser.

Size (MB)

the uncompressed size of the VTV (MB). <MOUNT> indicates that the VTV was mounted when the report ran. <FENCED> indicates that the VTV's state is unknown. If <FENCED> appears, contact Oracle StorageTek Software Support.

Comp %

the VTV compression percentage achieved. This is the difference between the uncompressed and compressed VTV size expressed as a percentage of the uncompressed VTV size. For example if a 100 MB VTV compresses to 40 MB then the compression% will be given as 60%. A compression of 0% indicates that no compression was possible on the VTV

Creation Date and Time

the date and time that the VTV was created.

Last Used Date and Time

the date and time that the VTV was last used. This date and time value is updated by successful completion of a VTV mount, migrate, recall, or scratch.

Mgr/Res

indicates the copy status of the VTV. The absence of a flag in the columns below indicates that there are no current copies of the VTV within this TapePlex.

An R in the left column indicates that there is a VTSS resident copy of the VTV
An M in the right column indicates that there is at lease one MVC copy of the VTV. As an alternative, if this column contains a C then the VTV is also consolidated.

Scr/Imp

indicates the usability of the VTV.

An S in the left column indicates that the VTV is in a scratched state. If the VTV has also been imported from a remote TapePlex, then the VTV cannot be picked for a scratch mount.
An I in the right column indicates that the VTV has been imported from another TapePlex. Imported VTVs cannot be modified.
An O in the left column indicates that the VTV has partial (write once) VOLSAFE protection.
An A in the left column indicates that the VTV has full VOLSAFE protection.

Repl/Expt

indicates the replication or electronic export status of the VTV. A VTV that is not resident does not have any replication requirements.

It can be one of the following statuses in the left column:

PR: The VTV is currently queued for replication.
SR: Replication of the VTV has started.
R: Replication has completed and another copy of the VTV resides in the partner to the currently resident VTSS.

It can be one of the following statuses in the right column:

PE

The VTV requires electronic export.

SE

Electronic export of the VTV has started.

FE

Electronic export of the VTV has been rejected by the remote TapePlex.

E

Electronic export has completed and another copy of the VTV resides in the partner to the currently resident VTSS.

ME

electronic export of this VTV to one TapePlex completed successfully, but an electronic export of this VTV to another TapePlex failed.

VTVRPT COPIES will provide the names of the two TapePlexes and indicate which one succeeded and which one failed.

MGMT Class

the name of the Management Class for the VTV specified.

MVC1, MVC2, MVC3, MVC4

the MVC(s) that contain the VTV (for both migration and consolidation). If all of these fields are empty, the VTV has not been migrated or consolidated. If one or more of these fields list an MVC volser, the VTV was migrated to each of these MVCs.

Max VTV

the maximum size of the VTV in GB (.4, .8, 2, or 4).

VTSSname

the VTSS where the VTV resides, or, if the VTV is migrated, the VTSS where the VTV was last resident. If this field is empty, the VTV is non-existent (not created or used, scratched, and deleted) or has been manually imported.

VTVRPt COPIES

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC not required

Description

The VTVRPt COPIES command generates a VTV report indicating where all current copies of a VTV reside.

Syntax

SLS0155I CONDITION CODE FOR UTILITY FUNCTION IS 0

Fields

The following list describes the fields for a report generated by the VTVRPt COPIES command:

VTV Volser: the VTV volser.
Size (MB): the compressed size of the VTV (MB). <MOUNT> indicates that the VTV was mounted when the report ran. <FENCED> indicates that the VTV's state is unknown. If <FENCED> appears, contact Oracle StorageTek Software Support.
MGMT Class: the name of the Management Class for the VTV specified.
Scr: indicates whether the VTV is in a scratched state. An S in this column indicates that the VTV is in a scratched state.
Primary: the name of the VTSS that contains the primary VTSS resident copy of the VTV. If this field is blank, then there are currently no VTSS resident copies of the VTV.
Replica: the name of the VTSS that contains a replica copy of the VTV. If this field is blank, then there are currently no VTSS resident replica copies of the VTV.
Owning Tapeplex: the name of the TapePlex that has ownership of this VTV. If this field is blank, then the VTV is owned by another TapePlex and can be processed normally. If this field is set, then the VTV has been imported from another TapePlex and its contents cannot be modified.
MVC1, MVC2, MVC3, MVC4: the MVC(s) that contain the VTV (for both migration and consolidation). If all of these fields are empty, the VTV has not been migrated or consolidated. The number next to each MVC volser is the ACS location of the MVC. If this is set to --, then the MVC is not library resident.
Export Tapeplex: the names of the TapePlexes to which copies of the VTV have been exported. The copies within these TapePlexes will show the VTV as imported and having an owning TapePlex name. This list is not exhaustive as some of these TapePlexes may have forwarded copies onto further locations. An asterisk (*) next to the name indicates an export that has been rejected by the target TapePlex.

VVAUDIT

Interfaces:

Utility only
UUI Support: Yes

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The VVAUDIT command synchronizes the vault allocation map with the vault volume records. If the slot in the map indicates that it is allocated, then the vault volume records are searched. If the slot number is not found in any vault volume record, then the slot is freed.

Syntax

Figure 3-186 shows VVAUDIT command syntax.

Figure 3-186 VVAUDIT command syntax

Surrounding text describes Figure 3-186 .

Parameters

As shown in Figure 3-186, the VVAUDIT command includes the following parameters:

VAULT(vault-name)

optionally, audits the specified vault-name. If VAULT is not specified, then all vaults are be audited.

vaultname indicates the vault name.

Warn

Interfaces:

Console or PARMLIB only
UUI Support: No

Subsystem Requirements:

Active HSC at BASE or FULL service level

Description

The Warn command sets scratch warning threshold values.

Setting a threshold value causes a warning message to be issued when the number of scratches falls below the specified threshold. The Warn command enables you to specify parameters that can narrow the scope of the threshold values you set:

If SUBpool, MEDia, and RECtech are not supplied, the threshold value applies to scratch volumes for the specified ACS or LSM.
If SUBpool is supplied, but MEDia and RECtech are not, the threshold value applies to scratch volumes for the specified subpool and ACS or LSM.
If MEDia and RECtech are supplied, but SUBpool is not, the threshold value applies to scratch volumes for the specified media type, recording technique, and ACS or LSM.
If SUBpool, MEDia, and RECtech are supplied, the threshold value applies to scratch volumes for the specified subpool, media type, and recording technique in the ACS or LSM.

Note:

Use the Display THReshld command to display the current Warn threshold values. See "Display THReshld" for more information.

Syntax

Figure 3-187 shows Warn command syntax.

indicates that scratch threshold values are to be set.

acs-id: the ACS on which to alter threshold values. The ACSid is a decimal value from 00-99.
lsm-id: the LSM on which to alter threshold values. The LSMid is comprised of the ACSid and the LSM number. The format of an LSMid is AA:LL, where AA indicates the ACSid (decimal 00-99) and LL indicates the LSM number (decimal 00-99).
VSM: specifies that threshold values are to be set only for subpools for virtual volumes. VSM is not allowed if acs-id or lsm-id are also specified.

SUBpool(subpool-name)

optionally, indicates that you want to designate a subpool. This parameter is optional.

subpoolname indicates the name of the subpool.

Note:

Scratch subpool names are specified with the SCRPOol control statement. Refer to Oracle's ELS publication ELS Legacy Interfaces Reference for information.

THReshld(threshold-value)

indicates that you want to alter the threshold value.

thresholdvalue indicates the minimum number of scratch volumes that are allowed before the HSC issues a warning message. Allowable threshold values are decimal in the range from 0 through 99,999.

The warning interval values are preset at five minutes.

Note:

When the number of scratch volumes in an ACS or LSM drops below the threshold value, the system issues a warning message.

MEDia(media-type)

optionally, specifies the media type for the threshold. When MEDia is specified, RECtech must also be specified.

media-type indicates the media type.

See Appendix A, "MEDia, RECtech, and MODel Values" for a list of valid media-type values.

RECtech(recording-technique)

optionally, specifies the recording technique for the threshold. RECtech indicates the method used to record data tracks on the tape surface. When RECtech is specified, MEDia must also be specified.

You can enter a list of recording techniques, but they must be separated by commas.

recording-technique indicates the recording technique.

See Appendix A, "MEDia, RECtech, and MODel Values" for valid recording-technique values.

Note:

A list specifies a generic pool from which a selection is made. There is no implied priority.
