HP StorageWorks P9000 Cluster Extension Software Administrator Guide (TB534-96009, February 2011)

If the resynchronization attempt fails, P9000 Cluster Extension will not fail. The
internal logic will first apply the concurrency and consistency rules to allow access
to the disk set.
If you configure fence level DATA for the device/copy group and set the FenceLevel
object to DATA, the AutoRecover object will change P9000 Cluster Extension's
behavior. P9000 Cluster Extension will attempt to re-establish the PAIR state and
wait for the PAIR state before it allows access to the disk. If the resynchronization
or takeover process fails, P9000 Cluster Extension returns a global error.
