After executing the pairsplit command on a Snapshot pair, you must confirm that pairs in the Snapshot consistency
group are all PSUS status before performing restore operations on the Business Copy pair. Otherwise it cannot be
ensured that the snapshot data of Snapshot is completely the same as the P-VOL data when the P9500 received the
pairsplit command. For details about Snapshot pair status and operation, see the HP P9000 Snapshot User Guide.

When the host accesses S-VOL of Snapshot, a response may be returned using data of Snapshot P-VOL. Therefore
you cannot perform the Quick Restore operation in reverse direction to swap the Business Copy P-VOL (Snapshot
P-VOL) and T-VOL.
OK: Operation can be performed No: Operation cannot be performed (Command is rejected)
