Switch access to backup server

Perform a cluster switchover when you want a backup server to access the switchable device containing an independent disk pool.

In a multisystem clustered environment that uses switchable independent disk pools, an independent disk pool can only be accessed by one node at a time. Current access to a switchable independent disk pool is managed through the switchover function within the cluster.

To switch access from the current node in the cluster to the first backup node:

1. The switchover may have already made the current node unavailable. If not, then from the current node, make a disk pool unavailable (vary off).
2. Switch the independent disk pool to the first backup cluster node by performing a switchover in the cluster. See Perform a switchover for details.
