1. On the first IBM eServer p5 520 server drs_engine1, replace the value in the
/usr/tivoli/tsm/client/ba/bin/dsm.sys file for the tcpserveraddress with your new HACMP cluster
service address. We recommend that you do NOT use a dot address, for instance
100.100.51.122 (if you must use an address, you should use the address provided by your
network administrator), use the TCP/IP domain name instead, that is drs_service_svc.
To replace the value, use an editor of your choice, for instance use vi (AIX command to start vi
and open the file is vi /usr/tivoli/tsm/client/ba/bin/dsm.sys).
If you are not familiar with AIX editors, you may want to use xedit, an X-window based editor. For
the latter, you first need to start an X-session. Start the X-session with the AIX command startx
(see startx manpages for details by issuing man startx). Then open the
/usr/tivoli/tsm/client/ba/bin/dsm.sys file with the AIX command xedit
/usr/tivoli/tsm/client/ba/bin/dsm.sys this will open a graphical editor session.
2. Save the file and exit the editor by using Save and Close on the scroll bar.
3. Connect to the IBM System Storage Archive Manager server from drs_engine1 with the
command dsmadmc. Login with the ITSM administrator admin and his password. Verify the
connection with the ITSM command query session. Exit the administrative command line client
with the ITSM command quit.
4. Switch to the second server, using the Prt Scr key. On the second P5 520 server drs_engine2,
replace the value in the /usr/tivoli/tsm/client/ba/bin/dsm.sys file for the tcpserveraddress with your
new HACMP cluster service address. We recommend that you do NOT use a dot address, for
instance 100.100.51.122 (if you must use an address, then use the address provided by the
network administrator), use the TCP/IP domain name instead, that is drs_service_svc.
To replace the value, use an editor of your choice, for instance use vi (AIX command to start vi
and open the file is vi /usr/tivoli/tsm/client/ba/bin/dsm.sys).
If you are not familiar with AIX editors, we suppose you use xedit, an X-window based editor. For
the latter, you first need to start an X-session. Start the X-session with the AIX command startx
(see startx manpages for details by issuing man startx). Then open the
/usr/tivoli/tsm/client/ba/bin/dsm.sys file with the AIX command xedit
/usr/tivoli/tsm/client/ba/bin/dsm.sys this will open a graphical editor session.
5. Save the file and exit the editor. In case you are running an X-session for your editor, quit the X-
session by pressing the Ctrl+Alt+Backspace key combination.
6. Connect to the IBM System Storage Archive Manager server from drs_engine2 with the
command dsmadmc. Login with the ITSM administrator admin and his password. Verify the
connection with the ITSM command query session. Exit the administrative command line client
with the ITSM command quit.
Tip: When using the TCP/IP domain name for the tcpserveraddress field in the IBM
System Storage Archive Manager client system options file (dsm.sys), you do not
need to change the value after a network reconfiguration. This is not true, when you
use the dot address.
