support/IBMTivoliStorageManager.html. If you are using the storage agent to
support multiple clients, you must install or upgrade the client and API
software on each client that will be supported.
2. Be sure you have the information recorded on the forms in “Configuration
Information Worksheets” on page 13. This information is required in this
procedure.
3. Modify the client options file (dsm.sys) For information about the dsm.opt and
dsm.sys files, see the Backup-Archive Clients Installation and User’s Guide.
a. Locate the options file and open it. The file could be located in one of
several places, such as the installation directory, or pointed to by an
environment variable.
b. Specify the Tivoli Storage Manager server name. This information will come
from the client system and server system configuration-information
worksheets. For example:
servername tsmsrver
Keep the file open for the next step.
c. Specify the communications method between the Tivoli Storage Manager
client and server. Again, this information will come from the client system
and server system configuration-information worksheets, as will the
information for the next steps. For example:
COMMmethod TCPip
TCPServeraddress tsmsrver.tucson.ibm.com
TCPPport 1502

Note: A TCPPORT of 1502 is used in the examples; however, the default

TCPPORT is 1500.
Keep the file open for the next step.
d. Edit the dsm.opt file to specify the server name of the dsm.sys stanza edited
in step 3b. For example,
servername tsmsrver
e. Add the following options to the same dsm.sys stanza edited in step 3b.
These options specify that the client will use SAN-attached devices when
the path is available, during backup, restore, archive, and retrieve
processing.
enablelanfree yes
LANFREECommmethod TCPIP
LANFREETCPPORT 1500
or
LANFREECommmethod SharedMem
LANFREESHMPORT 1510
4. If you are using a Tivoli Storage Manager data protection application client,
configure the API by performing the following procedure:
a. Set up the environment variables. The Tivoli Storage Manager API uses
unique environment variables to locate files.

v DSMI_CONFIG is the fully qualified name for the client user option file.

v DSMI_DIR points to the path containing dsm.sys, dsmtca, and the

subdirectory en_US.

v en_US subdirectory must contain dsmclientV3.cat.

v DSMI_LOG points to the path for the dsierror.log file

The following are examples on how to set up these environment variables.
