Editing the TSM client system options file

You can edit the IBM® Tivoli® Storage Manager (TSM) client systems options file, dsm.sys. This file must refer to the correctTSM server address and communication method.

The following TSM options are the most important to set in the dsm.sys file:

SERVERNAME: Specifies the name that you want to use to identify a server when it is referred to in the dsm.opt file and to create an instance that contains options for that server.
COMMMETHOD: Identifies the communication method.
TCPSERVERADDRESS: Identifies the TSM server.
PASSWORDACCESS: Specifies GENERATE to store the TSM password.
PASSWORDDIR: Directory where the Spectrum Protect client will store the SSL encryption related files and keystore.
NODENAME: Specifies the name of the Spectrum Protect client.
Note: Use the INFORMIXSERVER / DBSERVERNAME values in such a way that, it will be easy to identify in the Spectrum Protect catalog.

The SERVERNAME option in the dsm.opt and dsm.sys files define server instance names only. The TCPSERVERADDRESS option controls which server is contacted.

You can enable deduplication by including the DEDUP=CLIENTORSERVER option in the client system options file. You must also set the IFX_BAR_USE_DEDUP environment variable in the database server environment and restart the database server. See the Tivoli Storage Manager Backup-Archive Client Installation and User's Guide for information about configuring deduplication.

You can set up multiple server instances in the dsm.sys file. See the Tivoli Storage Manager Backup-Archive Client Installation and User's Guide for information about multiple server instances.
