Manual

• With a Quick Restore, RWC may show outdated information. Click Refresh View to ensure
the most up-to-date information.
• To keep the S-VOL and T-VOL unsynchronized when performing a Quick Restore, enable the
Swap&Freeze option prior to performing the operation. Update copy operations are then
suppressed when the Quick Restore is completed, and the pair is in DUPLEX status.
• If you perform a reverse or Quick Restore operation on a pair whose S-VOL is also paired
with other T-VOLs, the S-VOL and other T-VOLs are no longer synchronized.
• For Reverse Copy or Quick Restore operation, the following restrictions apply:
Pairs sharing the same S-VOL must be split (Split/SUSPOP status) or suspended
(Suspend/SUSPER status).
◦
◦ If the pair shares a volume with Cnt Ac-S Z or Cnt Ac-J Z, the Cnt Ac-S Z or Cnt Ac-J Z
pair must be suspended to perform either backward resync operation.
◦ You cannot create a Cnt Ac-S Z or Cnt Ac-J Z pair with a volume shared by BC Z during
either backward resync operation.
◦ When the Reverse Copy or Quick Restore operation is in progress, you cannot create,
split, or resync any pair sharing the same S-VOL. You can delete or suspend the pairs,
however.
◦ The Quick Restore operation cannot be performed on a Cross OS File Exchange pair.
1. In the RWC, click Actions > Local Replications > BC Z/FC Z > Pair Operation.
2. Change to Modify mode by clicking the icon.
3. In the tree, in the Pair Operations window, select the CU image where the pairs or volumes
are located.
Related volumes are shown in the volume list. If a volume is already paired, pair information
is also shown.
4. In the volume list, select the pairs to be resynchronized, right-click, and select Resync Pair.
5. In the Resynchronize Volume Pair dialog box, select the Resync Type as follows:
• Normal Copy(S->T) to resynchronize the pairs normally. All differential data is updated
to the T-VOL.
• Quick Resync(S->T) to immediately change pair status to DUPLEX. Resynchronization of
data does not occur immediately. Differential data is copied during update copying.
• Reverse Copy(T->S) to copy the T-VOL data to the S-VOL. All differential data is updated
to the S-VOL.
• Quick Restore(T->S) to swap the S-VOL and T-VOL. Any differential data between the
volumes is copied during update copying.
