Splitting a pair of data volumes

The primary and secondary disk array administrators can perform the following procedure:
1. Ensure that the Command View XP or XP Remote Web Console main pane is in Modify mode. For
more information, see the HP StorageWorks Command View XP User Guide for XP Disk Arrays or the
HP StorageWorks XP Remote Web Console User Guide for XP12000/XP10000.
2. Ensure that the Pair Operation pane is displayed (see ” Displaying the Pair Operation pane ” on
page 105).
3. In the tree, select Subsystem or a port.
4. In the list, select and right-click the pair you want to split. The pair status must be COPY or PAIR.
5. Select Pairsplit-r. The Pairsplit-r pane appears.
6. In the Pairsplit-r pane, select the desired pairsplit options for the pairs.
7. Click Set to close the Pairsplit-r pane.
8. In the Preset list in the Pair Operation pane, check the settings you made.
• To modify a setting, select and right-click the setting, and select Modify.
• To cancel a setting, select and right-click the setting, and select Cancel.
9. Click Apply to split pairs.
NOTE: If an error occurs, the right-most column of the Preset list displays the error code. To view
detailed information about the error, right-click the error code, and select Error Detail. An error
message appears providing detailed information about the error.
10. In the list of the Pair Operations pane, verify that the pair was split successfully. If the pair was split, the
status of the pair is PSUS.
NOTE: To restore a pair that has already been split, use the Pairresync command (see ” Restoring a pair of
data volumes” on page 120 ).
