HP StorageWorks XP Remote Web Console Software - Manual (Page 81)

To remove any volumes from the Split Volume Pair Volume List or the T-VOL List, select the volumes,
right-click the selected volumes using the mouse, and then click the Delete command from the pop-up
menu that appears after right-clicking.
Splitting Pairs
To split one or more existing Siz pairs:
1. If you want the T-VOLs you are intending to split to be identical to the S-VOLs, stop all write
operations to the S-VOLs before 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 Siz asynchronous update copy operations, this status transition can
take several minutes.
2. Go to the Siz main window, and select the desired CU image or S-VOL in the Tree to filter the
volumes displayed in the Volume List.
3. Select the pair(s) you want to split, right-click the mouse to display the pop-up menu, and then
select the Split Pair command to open the Split Volume Pair dialog box.
NOTE:
You cannot split a suspended pair.
4. On the Split Volume Pair dialog box, select from the Copy Pace drop-down list, the copy pace
(Slower, Medium, or Faster) for all pairs being split.
NOTE:
If you change the setting, the last setting becomes effective.
5. Click the split type (Quick Split or Steady Split) for all pairs being split from the Select Split
Type drop-down list.
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 dialog box displays the desired pair(s), click the OK button to reflect
all pairs to the Preset List on the Siz main window.
NOTE:
Use the Delete command selected from the pop-up menu (displayed by right-clicking) to remove
any pairs from the Preset List.
7. On the Siz main window, click the Apply button to apply the Split Volume Pair operation(s) set in
the Split Volume Pair dialog box to the HP StorageWorks XP12000 storage system. When the
Split Volume Pair operation(s) start, the Siz 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.
