Splitting a Pair of Data Volumes
After the initial copy operation finishes, you can use the Suspend Pair window to split the pair of
data volumes.
To split one or more pairs, follow the procedure below. Not only the primary storage system
administrator but also the secondary storage system administrator can perform this operation:
1.
Ensure that the XP Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see XP Remote Web Console user’s guide.
2.
Ensure that the Pair Operation window is displayed.
3.
In the tree, select a CU number.
4.
In the list, select and right-click the pair that you want to split.
The pair status must be Duplex.
5.
From the pop-up menu, select Suspend Pair.
The Suspend Pair window appears (
“Suspend Pair Window” (page 152)
).
6.
In the Suspend Pair window, select the desired pairsplit options for the pair(s).
7.
Select Set to close the Suspend Pair window.
8.
See the Preview list in the Pair Operation window to check the settings that you have made.
•
To modify a setting, select and right-click the setting and then select Modify.
•
To cancel a setting, select and right-click the setting and then select Cancel.
9.
Select Apply to split pair(s).
10.
In the list of the Pair Operations window, verify that the pair has been split successfully. If the
pair has been split, the status of the pair is Suspend.
NOTE:
To restore a pair that has already been split, use the Resume Pair command.
In either of the following conditions, the secondary data volume may become suspended due
to a failure:
•
You split a pair when the primary data volume is reserved by a mainframe host.
•
The primary data volume becomes reserved when you split the pair.
If the secondary data volume is suspended due to a failure, you can restore the pair by using
the Resume Pair command.
