You need to adjust the IBM Tivoli Storage Manager (ITSM) client system options file, so that the
ITSM API or any ITSM client (dsmadmc) can find the IBM Tivoli Storage Manager server.
On the p5 520 server, replace the value in the 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
100.100.51.121, instead, use the TCP/IP domain name instead, that is drs_engine.
Tip: When using the TCP/IP domain name for the tcpserveraddress field in the IBM
Tivoli Storage 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.
Step 7 - Logoff all sessions
After successful configuration you should exit all shells with the AIX command exit. Depending on
the actual shells, you must type the exit command more than once. For example, enter exit one
time to close the shell of root and one time to close the shell of dr550. Repeat it until you see the
AIX login prompt on the management console session.

Changing passwords
It is strongly recommended to change the default passwords set at the factory. It is also a good
practice to change the passwords on a regular basis. Change passwords for the HMC, AIX operating
system, and the IBM Tivoli Storage Manager users:
AIX
For the AIX operating system (for both IBM eServer p5 520 servers) you should change the
passwords for all four preconfigured system accounts (dr550, dr550adm, ibmce, root). Because of
AIX security restrictions with the DR550 SMB, the most convenient way to change passwords is to
log in with the user whose password you want to change, and then change the password; root is
allowed to change passwords for other users but then these users are forced to change their
password again the next time they log in.
Therefore, the procedure for every distinct user account is:
Use the management console to access the first IBM eServer p5 520 (use PrtSc button,
select Engine1 on Port 01 from the panel, press Enter)
o Login to AIX using the dr550 user with the appropriate password.
o Change the password of dr550 with the AIX command passwd. Follow the instructions
on the screen.
o Switch to the root user ID and his environment with the AIX command su - root and
provide root’s password.
o Change the password of root with the AIX command passwd. Follow the instructions on
the screen.
o Switch to the dr550adm user ID and his environment with the AIX command su -
dr550adm.
o Change the password of dr550adm with the AIX command passwd. Follow the
instructions on the screen.
o Exit the shell back to the root environment with the AIX command exit.
