NOTE: The following concerns possible post-resync conditions:

• Make sure that pair status changes to PAIR before attempting any other operation.

• If the reverse or quick restore operation ends abnormally, the pair status changes to PSUE. In

this case, the primary volume is read/write-enabled for all hosts, but the data is not guaranteed.

The secondary volume remains write-disabled and data is not guaranteed. The status of other

pairs sharing the same primary volume does not change.

Pair deletion

You can delete a pair when you no longer need it. When you delete a pair, the primary and

secondary volumes return to their SMPL state, though their data remains intact. After deletion, both

volumes are available for use in another pair.

NOTE: When pair status becomes SMPL, it no longer displays in Remote Web Console.

Prerequisite information for deleting pairs

• The primary and secondary volumes must be synchronized. Before deleting, wait until all write

I/O operations to the primary volume are completed, set the primary volume offline, then split

the pair.

• Pair deletion cannot be performed when the pair status is PSUS(SP)/PSUS.
