Upgrading PowerHA? Don't forget your TSM client!

When you upgrade PowerHA (formerly HACMP) don’t forget to check/update your TSM client as well!
We successfully upgraded from PowerHA 5.4 to PowerHA 6.1 SP6 first.
# halevel -s
We found that our
DB2 backups to TSM were no longer working.
$ db2adutl query
Error: Initialize environment failed with TSM return code 4602
In the TSM error log file we also saw the following message repeated over and over:
# tail -1 dsmerror_db2_ha.log
10/17/11 12:42:57 ANS1478E CLUSTERNODE is set to YES but the cluster software is not available on this system.
Obviously cluster services were most
certainly installed and running! So we suspected the TSM client was in need of
an update or two! This was no surprise to us.
The current installed TSM client version was 5.5.2.
# lslpp -L tivoli*
tivoli.tivguid 126.96.36.199 C F IBM Tivoli GUID on AIX
We upgraded the TSM client to version 6.2.
# lslpp -l tiv*
188.8.131.52 COMMITTED TSM Client - Application
Now our DB2 connection to the TSM server was working again.

We also discovered that we needed to comment out the following entries in the TSM client dsm.sys file (note the MAILPROG variable appeared twice in our dsm.sys file):
The latest TSM client no longer supports the MAILPROG option, as we discovered when we ran the TSM client from the command line:
# dsmc q sess
ANS1677W The MAILPROG option is ignored because it is no longer supported.

The CLUSTERNODE option was previously required when using TSM in a PowerHA (HACMP) environment. But not anymore:
Do tsm client 6.1 and 6.2 support PowerHA cluster system?
TSM client supports all versions of PowerHA. In the past, TSM client used to publish information in the client books about the HACMP versions that it supported. The reason for this was, at that time TSM client was invoking the HACMP API in order to support it. From TSM version 6.1, TSM client does not use the HACMP API. As long as TSM client is configured with HACMP as documented in the client books and the HACMP documentation, TSM will be able to support any version of PowerHA (formerly known as HACMP).
