4. In the Pairresync window, select the pairs, and set the copy pace (Slower, Medium, or Faster)
and resync type (Normal Copy, Quick Resync, Reverse Copy, or Quick Restore) for each pair.
Reverse and quick restore pairresync cannot be performed on suspended pairs (PSUE) or L2
cascade pairs.
NOTE:
When a quick restore operation is in progress, the array management user interface may
display old configuration information. To update the information in the user interface, wait
for the quick restore operation to finish, and click Refresh.
CAUTION:
Ensure that the correct resync direction (normal/quick, or reverse/quick restore) is selected.
CAUTION:
During the quick restore operation, the RAID levels, HDD types, and Cache LUN settings
are swapped. To avoid performance impact due to quick restore operations:
• Ensure that the P-VOL and S-VOL have the same RAID level and HDD type before per-
forming the quick restore operation. To restore the original RAID levels after quick restore,
stop host I/Os to the pair, split the pair, perform the quick restore operation for that
pair again, and restart host I/Os to the pair.
• Because the Cache LUN settings are exchanged during a quick restore operation, you
must perform one of the following operations. If you do not, the change of location of
the cache residence areas may cause I/O performance to the Cache LUN data to be
down.
• Set the same Cache LUN settings (locations) for the P-VOL and S-VOL before per-
forming the quick restore operation.
• Release the Cache LUN settings of the P-VOL and S-VOL before the quick restore
operation, and reset the Cache LUN settings of the P-VOL and S-VOL after the pair
changes to PAIR status as a result of the quick restore operation.
If you do not want to resynchronize the P-VOL and S-VOL after the quick restore operation,
set the Swap&Freeze option before performing the quick restore operation.
5. Click OK. Repeat step 4 — step 5 until the Preset Volume list on the BC main screen displays the
pairs (settings).
NOTE:
Ensure that the S-VOLs are taken offline before starting pairresync operations.
6. In the BC main screen, click Apply to resync the specified pairs.
The BC main screen displays the results of the pairresync operations (that is, the pair status
changed to COPY(RS), COPY(RS-R), or PAIR).
7.
Click Refresh ( ) to monitor the progress of the pairresync operations.
