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.
