Splitting Pairs
The Pairsplit dialog box (see Figure 33 (page 75) ) allows you to split existing XP Business Copy
pairs. The Pairsplit dialog box can also be used to simultaneously create and split new XP Business
Copy pairs.
For information about how to split pairs, see “Performing Only Pair Splitting” (page 78) . For
information about how to create and split pairs, see “Performing Pair Creation and Pair Splitting”
(page 79) . In addition, you can split multiple pairs at the same specified time by using RAID
Manager. For details, see “Performing At-Time Split Operation (Multiple Pair Splitting)” (page 80) .
