9. Make sure to verify that the S-VOLs are offline before starting the pairresync operations.
10. On the Pair Operation window, click Apply to resynchronize the specified pairs.
The Pair Operation window displays the results of the pairresync operations (that is, pair status
changed to COPY(RS), COPY(RS-R), or PAIR) and the progress (%) of the update copy operation.
The pair status will change to PAIR right away, if the update copy operation is not necessary.
CAUTION:
•
When reverse or quick restore resync operation ends abnormally, or Pairsplit-E (PSUE) is
requested during reverse or quick restore resync operation, the pair status changes to PSUE.
The P-VOL of the PSUE pair is read- and write-enabled for all hosts; however, the data on the
P-VOL is not guaranteed. The S-VOL of the PSUE pair remains write-disabled (read-only);
however, the data on the S-VOL is not guaranteed.
•
Even when reverse or quick restore resync operation ends abnormally, or Pairsplit-E (PSUE) is
requested during reverse or quick restore resync operation, the status of other XP Business
Copy pairs that share the same P-VOL does not change.
Deleting Pairs

is an operation to stop copying data into the S-VOL of an XP Business Copy pair, and set the status
of the P-VOL and S-VOL back to SMPL volumes.
