•
The Copy Pace list allows you to select the copy pace (from Slower, Medium, or Faster) for all
the pairs that you are resynchronizing.
When resynchronizing pairs, you can select the pace for the pairresync operations: slower,
medium, or faster. The slower pace minimizes the impact of XP Business Copy operations on
storage system I/O performance. The faster pace resynchronizes the pairs as quickly as
possible, but it may affect the storage system I/O performance.
•
The OK button adds the operation setting displayed in the Pairresync Volume List for
resynchronizing the specified pairs to the Preview List on the Pair Operation window.
You must click Apply on the Pair Operation window to start the pairresync operation for the
specified pairs.
•
The Cancel button cancels the operations set in the Pairresync dialog box and closes the dialog
box.
To resynchronize one or more XP Business Copy pairs that have been split or suspended:
1.
Unmount the split (PSUS) S-VOLs from the host before starting the pairresync operations.
When the pairresync operation starts, the storage system will stop accepting write I/Os to the
S-VOL.
2.
Go to the Pair Operation window, and select the desired port or host group in the Tree to
filter the volumes displayed in the Volume List.
3.
On the Pair Operation window, select the pairs in PSUS, PSUS(SP), or PSUE status, right-click
the selected pairs to display the menu, and then select the Pairresync command to open the
Pairresync dialog box.
4.
On the Pairresync dialog box, select the pairs you want to resynchronize.
To remove the pairs in the Pairresync Volume List, select and right-click the pair, and then
select the Delete command in the menu.
5.
Select the desired copy pace from the Copy Pace list.
6.
Select the desired resync type for each pair from the Resync Type list.
IMPORTANT:
Make sure to select the correct resync direction (normal/quick, or reverse/quick
restore).
CAUTION:
•
If you do not want the P-VOL and S-VOL to be resynchronized after the quick restore
operation, you must set the Swap&Freeze option before performing the quick restore
operation (see
and
).
•
If the reverse or quick restore pairresync operation is performed on one XP Business Copy
pair in a 1-to-n XP Business Copy configuration (n>1), the P-VOL and the other S-VOLs
are no longer synchronized.
•
Reverse and quick restore operations cannot be performed on pairs in the PSUE or
PSUS(SP) status, or on L2 cascade pairs.
•
When a quick restore operation is in progress, the Remote Web Console window may
display old configuration information on components such as logical volumes (LDEVs);
the window may display configurations before the quick operation is performed. To
update configuration information on the Remote Web Console window, wait until the
quick restore operation completes and then click File and then Refresh on the menu bar
of the window.
