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.
