Configuring an AIX environment for clustering

You can configure the IBM Storage Protect server for AIX® clustered environments by using IBM® PowerHA® SystemMirror® for AIX or IBM Tivoli System Automation for Multiplatforms.

PowerHA SystemMirror for AIX and System Automation for Multiplatforms detect system failures and manage failover to a recovery processor with a minimal loss of user time. You can set up the IBM Storage Protect server on a system in a PowerHA or a System Automation for Multiplatforms cluster. Then, if the system fails, the IBM Storage Protect server can be started on another system in the cluster.

In both failover and failback, it seems that the IBM Storage Protect server halted and is then restarted. Any transactions that were in progress at the time of the failover or failback are rolled back, and all completed transactions are still complete. IBM Storage Protect clients see failover or failback as a communications failure and try to reestablish their connections.
