HP XP P9000 Business Copy User Guide (AV400-96573, July 2013)

• For Reverse Copy or Quick Restore, the pair must be in PSUS status.
• The pairresync normally takes less time when the pair is in PSUS status than when it is in PSUE.
This is because the amount of differential data accumulated for a split pair is usually much
less than the total amount of data in the P-VOL, which must be copied in full when the pair
was suspended by the storage system.
• To keep the P-VOL and S-VOL unsynchronized when performing a Quick Restore, enable the
Swap&Freeze option prior to performing the operation. Update copy operations are then
suppressed when the Quick Restore is completed, and the pair is in PAIR status.
• If a pair consists of encrypted volumes and a non-encrypted volume, and the Quick Restore
is run, the P-VOL and S-VOL encryption statuses are reversed.
• With a Quick Restore, RWC can show outdated information. Click Refresh View to ensure
the most up-to-date information.
