This chapter describes the initial tasks required for you to begin to use LTFS-LE. It also introduces the LTFS-LE browser based user interface (BUI).
The following topics are included:
Ensure that you have installed the following software:
LTFS-LE 1.0 software
LTFS Open Edition (LTFS-OE) software
Refer to the StorageTek Linear Tape File System, Library Edition Planning and Installation Guide for more information.
To verify that LTFS-OE is installed, issue the ltfs -V
command from the LTFS-LE server. See "Displaying Oracle Enterprise Linux (OEL) Version" for more information.
LTFS-LE supports a single ACS/library, either a dedicated library or a zoned library partition. Ensure that you have configured the SL150, SL3000 or SL8500 tape library with appropriate drives and media. Using the SLConsole, ensure that the library partition has drive bays, storage cells, and an HLI library CAP.
Additionally, define the following settings:
Use the ACSLS command, config_acsss
, option 3 to configure the following parameters:
Number of days to retain volumes that are identified as ABSENT or EJECTED to the database should be set to zero (0).
Select the default (TRUE) to support alphanumeric volume ranges for commands and utilities. Alphanumeric ranges include all valid vol_ids in ASCII collating sequence.
Note:
Changes to alphanumeric volume ranges will not take effect until ACSLS is restarted.Set your CAP to manual mode:
set cap priority <cap_id>
Example:
set cap priority 5 2,0,6
Refer to the StorageTek Automated Cartridge System Library Software Installation Guide for more information about the config_acsss
command.
To verify drive connections, perform the following steps to compare drive serial numbers in ACSLS with drive serial numbers on the LTFS-LE server.
Use the ACSLS display
command to display your drive serial numbers:
display drive * -f type serial_num
Example Output:
ACSSA> display drive * -f type serial_num 2013-07-19 15:34:13 Display Drive Acs Lsm Panel Drive Type Serial_num 2 0 10 6 T1C 576001000518 2 0 10 7 HP-LTO5 HU1246T5MV 2 0 10 11 HP-LTO5 HU1246T5PW
Display the drive serial numbers on the LTFS-LE server:
lsscsi -g | grep -i tape
Output Example:
# lsscsi -g | grep -i tape [7:0:0:0] tape HP Ultrium 5-SCSI I59S /dev/st0 /dev/sg5 [9:0:0:0] tape STK T10000C 1.57 /dev/st1 /dev/sg6 [11:0:0:0] tape HP Ultrium 5-SCSI I59S /dev/st2 /dev/sg7 sg_ing </dev/sq#> | greap "Unit serial number"
Output Example:
# sg_inq /dev/sg5 | grep "Unit serial number" Unit serial number: HU1246T5MV # sg_inq /dev/sg6 | grep "Unit serial number" Unit serial number: 576001000518 # sg_inq /dev/sg7 | grep "Unit serial number" Unit serial number: HU1246T5PW
Verify that the serial numbers from steps 3 and 4 match using the display
drive
command output from ACSLS cmd_proc
.
Refer to the StorageTek Automated Cartridge System Library Software Installation Guide for more information about the display
and cmd-proc
commands.
After you configure the physical tape library, you must access the LTFS-LE browser based user interface (BUI) to define the library in the LTFS-LE application.
The LTFS-LE BUI is used primarily by the LTFS-LE System Administrator to perform various administrative tasks and monitor LTFS-LE system performance.
The LTFS-LE BUI resides on the LTFS-LE server and is accessed from a standard web browser such as Windows Explorer or Mozilla Firefox.
You can use the LTFS-LE BUI to do the following:
Discover library resources
Monitor the LTFS-LE system, including online capacity, drive availability, and LTFS-LE events.
Manage drives and volumes, placing them online or offline, assigning them to LTFS-LE, and adding them to the LTFS-LE default drive and volume pools.
Enter, eject, and vault volumes.
Format or unformat volumes for use with LTFS-LE.
Schedule a local LTFS-LE system backup.
The BUI is installed as part of LTFS-LE. Refer to the StorageTek Linear Tape File System, Library Edition Planning and Installation Guide for more information.
The following figure shows the LTFS-LE BUI:
