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)
