Hi
First, officially, the new B/A clients do have HACMP support. There is
also complete scripts to do this installation.
Inofficially, I have clients running HACMP, but also TSM servers running
HACMP with fail-over support. Only HACMP installation that is not
supported is using HACMP with Concurrent Access.
Yes, we have done restores of clients running HACMP, and it works well.
Only thing you have to do, is to move the TSM Client services with the
involved resource group.
For TSM servers, the installation is a bit more tricky, but it works. We
have an installation running 2 P-Series 660 servers and HACMP. On this
server, they are running TSM ver 4.2. They have about 450 clients, and
restores are being done one a daily basis.

Subject: b/a client & HACMP: failover support
Dear gurus,
The manual "Tivoli Storage Manager for AIX: Quick Start" v5.1 (First
Edition, March 2002, GC32-0770-00) says "the backup-archive client is
not supported with HACMP and should not be used on the production or
standby nodes because it does not contain failover support" (pg. 74,
par. "Installing the Tivoli Storage Manager Client on the Production
Node").
What does it mean? I'm quite sure that the following cascading-mutal
takeover scenario could work fine:
Node A
Resource group node A: TSM b/a client (it backups the filesystems owned
by node A of the shared volume group handed by HACMP) + TDP for Oracle
+ TSM server
Node B
Resource group node B: TSM b/a client (it backups the filesystems owned
by node B of the shared volume group handed by HACMP) + TDP for Oracle
In case of failure of the node A,
1) the node B continues its activities (this is Oracle instances +
backup oracle/files of the node B) and
2) the node B starts the activities of the node A (this is Oracle
instances + backup oracle/files of the node A + TSM server)
