Splitting Pairs
The Split Volume Pair dialog box (see Figure 33 (page 74)) allows you to split existing ShadowImage
for Mainframe pairs. The Split Volume Pair dialog box can also be used to simultaneously add
and split new SIz pairs.
For information about how to split pairs, see “Performing Only Pair Splitting” (page 77). For
information about how to create and split pairs, see “Performing Pair Addition and Pair Splitting”
(page 77). In addition, you can split multiple pairs at the same specified time by using XP for
Business Continuity Manager Software™. For details, see “Performing At-Time Split Operation
(Multiple Pair Splitting)” (page 78).
