ibm3494 - The IBM3494 interface through lmcpd
ibm3494 is the Sun QFS and SAM-QFS interface to the IBM 3494
library. This interface utilizes the lmcpd interface sup-
plied by IBM. For more information on configuration and
interfacing the IBM libraries, see the documentation sup-
plied with the IBM hardware and for lmcpd.
It is assumed that the site has the lmcpd daemon configured
and operating with the 3494 library.
The "equipment identifier" field in the mcf file, (see
mcf(4)), is the full path name to a parameters file used by
ibm3494. This file consists of keyword = value and
path_name = value pairs. All keyword/path_name/values are
The keywords are:
name This is the name assigned by the system administra-
tor and configured in the /etc/ibmatl.conf file and
the symbolic name of the library. This parameter
must be supplied, there is no default.
The category is a hex number between 0x0001 and
0xfeff. Media controlled by Sun QFS or SAM-QFS will
have its category set to this value. The default
for category is 4.
access Access to the library may be shared or private. If
private, then any media imported into the library
(category = 0xff00) will be added to the catalog and
its category will be changed to that specified by
category above. If shared, then the import command
(see import(1M)) will have to be used to add media
to the catalog. The default for access is private.
There is one device_path_name entry for every drive
in the library attached to this machine. This name
must match the Equipment Identifier of an entry in
the mcf file. Following the device_path_name is the
"device number" as described in the IBM documenta-
tion. The system administrator can determine this
number by running the IBM supplied utility mtlib.
Following the device number is the shared parameter.
This parameter is optional and is used to indicate
the drive is shared with other Sun QFS or SAM-QFS
servers. See examples below.
The example uses the following file and information obtained
from the IBM supplied utility mtlib. Both are documented in
the materials supplied by IBM.
# This is file: /etc/ibmatl.conf
# Set this file up according the documentation supplied by IBM.
3493a 18.104.22.168 test1
After lmcpd is running, run mtlib to get the device numbers.
mtlib -l 3493a -D

Import media into the library by placing the new media into
the I/O slots and closing the door. The library will lock
the door and move the media into the storage area. Only 100
volumes can be imported at one time. If you are running
with access=private, the library will inform the daemon as
the media is moved and the media will be added to the cata-
log. If running with access=shared, then an import (see
import(1M)) command will need to be executed to add the
media to the catalog.
Exporting media (in all modes) is performed by the export
(see export(1M)) command. This command will move the media
to the I/O area and the output mode light on the operator
panel will light. The operator can then remove the media
from the I/O area.
If running with access=shared then a catalog will need to be
built before starting Sun QFS or SAM-QFS. There are two
utilities used to maintain the library catalog. build_cat
(see build_cat(1M)) is used to build the catalog. dump_cat
(see dump_cat(1M)) and build_cat together are used to change
the size of the catalog.
To initialize a catalog with 1000 slots run:
build_cat /tmp/catalog_file < /dev/null
then move /tmp/catalog_file to the path pointed to in the
mcf file for this library. (In this case
/var/opt/SUNWsamfs/catalog/ibmcat). Use import to populate
the catalog with the volumes. Or, you can create a file
with the list of volumes and supply it as input to build_cat
(see build_cat(1M) for the format of the input file).
If the size of the catalog needs to be increased, execute
dump_cat file1 | build_cat -s 2000 /tmp/file2
This would create a new catalog file (/tmp/file2) with room
for 2000 entries and initialize it with the entries from
file1. This can only be done when the Sun QFS or SAM-QFS
software is not running and sam-amld has been shutdown (see
mcf The configuration file for the
Sun QFS and SAM-QFS software.
