Adding Pairs
WARNING: The ShadowImage for z/OS add pair operation overwrites all data
on the T-VOLs. The user is responsible for backing up the data on the T-VOLs
before adding SIz pairs.
The Add Pair dialog box (see Figure 5-5) allows you to select the T-VOL(s) for
each S-VOL, set the copy pace for all pairs being added, and start the Add Pair
operation(s).
If you want to add new SIz pairs and then split them immediately so that you
can access the T-VOLs as soon as possible, add the pair from the Split Pair
Volume dialog box instead of the Add Pair dialog box. For details, see section
Performing Pair Addition and Pair Splitting.
