HP StorageWorks XP Cluster Extension Software Administrator Guide (T1656-96035, April 2010)

XP Cluster Extension resources go offline because the primary volume state changes from P-VOL_PAIR
to P-VOL_PSUE and the secondary volume state changes from S-VOL_PAIR to EX_NORMT.
The state combination P-VOL_PSUE and EX_NORMT is not designed to be handled automatically
because the remote side (remote XP RAID Manager/ disk array), which has no status information
available, could have more current data then the primary (P-VOL_PSUE) site. In this particular case,
you are required to investigate data currency and determine the appropriate action to be taken.
