Performing Only Pair Splitting
CAUTION: 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.
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.
To split one or more existing SIz pairs:
1. Go to the Pair Operation window, and select the desired CU image or S-VOL in the Tree to
filter the volumes displayed in the Volume List.
2. Select and right-click the pairs you want to split (other than the suspended pairs) to display
the menu, and then select the Split Pair command to open the Split Volume Pair dialog box.
3. On the Split Volume Pair dialog box, select from the Copy Pace list, the copy pace for all pairs
being split.
The copy pace is set for all pairs being split. If you change the setting, the last setting will
become effective.
