Clarence,

I am not quite sure what you are asking for.  I have experience with
administering HACMP, ADSM and AIX all in the same environment.

If you are looking at setting up an ADSM server, and are not sure if you need
an HA cluster, the question to ask is, How important is it to have
ADSM available 99.99% of the time in a 7x24 environment?

If you are looking at adding ADSM onto a HA cluster, then there are some
things to look at, like making sure the database and recovery logs
will be available after the take over.
