The actual script would process the cartridge list from stdin (identified by the "ISV" tag at the
beginning of the line) and use the NetBackup CLI to trigger a tape import on the specified library.
For example:
#!/bin/bash
#set -x
#read from stdin
CARTLIST=`grep ISV~ /dev/stdin`
for CART in $CARTLIST
do
BARCODE=`echo $CART | awk -F"~" '{print $2}'`

BCSLOT=`echo $CART | awk -F"~" '{print $4}'`

IBM TSM

This section includes both general and deduplication guidelines as well as other useful information
for IBM TSM.

TSM General Guidelines

The following TSM guidelines apply to a VLS regardless of whether deduplication is enabled or
disabled:
• Configuration of libraries: See the HP StorageWorks Enterprise Backup Solution with Tivoli Storage
Manager implementation guide for details on how to configure the device drivers for HP libraries
and drives, including how to set the library element numbers, install the appropriate "tsmscsi"
drivers, etc.
The "HP VLS" library emulation is only supported in TSM version 5.5.2.1 or higher.
• Disable client compression: When configuring clients on the TSM server, HP recommends not en-
abling client compression. The built-in compression in the virtual library device gives better per-
formance. In addition, the client compression prevents deduplication from operating. Therefore,
when registering a new client node on the server, set the client compression setting to NO rather
than CLIENT. The default value for the COMPression parameter for the REGister Node com-
mand is CLIENT.
• TSM server/client performance: There are a multitude of settings available in the TSM server options
file that make TSM very configurable in a wide variety of environments. However, there are a few
key recommended settings shown in
and restore to tape libraries. See the IBM Tivoli Storage Manager Performance Tuning Guide for
more information on server and client performance.
