CAUTION:
The S-VOL and T-VOL are synchronized only when the pair status changes from SP-Pend
or V-Split to Split. Due to the SI390 asynchronous update copy operations, this status transition can
take several minutes.
2.
From the ShadowImage main window, click the CU image or LDEV in the Tree View box to filter the
volumes displayed in the Volume List box.
3.
Select the pair(s) you want to split, right-click to display the pop-up menu, and then click Split Pair to
open the Split Volume Pair window. You cannot split a suspended pair.
4.
From the Split Volume Pair window, set the copy pace (Slower, Medium, or Faster) for all pairs being
split.
NOTE:
If you change the setting, the last setting will become effective.
5.
Set the split type (Quick Split or Steady Split) for all pairs being split.
NOTE:
The split type is set for all pairs being split. If you change the setting, the latest setting is
applied to all pairs.
6.
When the Split Volume Pair window displays the pair(s), click OK to reflect all pairs to the Preset
Volume List box on the ShadowImage main window.
NOTE:
Use the Delete command to remove any pairs from the list.
7.
From the ShadowImage main window, click Apply to split the pair(s).
When the pairsplit operation(s) start, the ShadowImage main window shows the new pairs with
SP-Pend or V-Split status and the progress (%) of the update copy operation(s). The Split status is
displayed right away if there were no pending update copy operations.
8.
Click the Refresh button (
) to monitor the progress of the split operation(s).
Adding and Splitting Pairs
The split operation can also be used to simultaneously add and split new SI390 pairs. In this case, the split
operation changes the pair status from simplex to SP-Pend or V-split, copies all data on the S-VOL to the
T-VOL, and then changes the pair status to Split.
NOTE:
The combined add and split operation can be performed using PPRC commands. Refer to
To add and split one or more new SI390 pairs with a single Command View XP or XP Remote
Web Console operation:
1.
If you want the split T-VOLs to be identical to the S-VOLs, stop all write operations to the S-VOLs before
adding and splitting the pairs. This ensures that there are no updates to the S-VOLs while the split
operations are synchronizing the T-VOLs to the S-VOLs.
CAUTION:
The S-VOL and T-VOL are synchronized only when the pair status changes from SP-Pend
or V-Split to Split. Due to the SI390 asynchronous update copy operations, this status transition can
take several minutes.
2.
From the ShadowImage main window, click the CU image or LDEV in the Tree View box to filter the
volumes displayed in the Volume List box (for example, to display unreserved simplex volumes).
