Use the following process to create FS pairs using RWC:
1. Select the pair configuration.
2. Select the P-VOL.
3. Select the S-VOLs.
4. Perform confirmation.
Configuring a complex pair
If you add S-VOLs to an existing pair, ensure that the Number of Secondary Volumes field contains
a number that is larger than the current number of S-VOLs of the existing pair.
For example, if you add an S-VOL to an existing pair that has one P-VOL and one S-VOL, specify
2 for the number of S-VOLs.
Figure 2 Adding an S-VOL to an existing pair
If you simultaneously create multiple pairs among which the number of S-VOLs differs, ensure that
Number of Secondary Volumes is the largest number among those pairs. Then, when selecting
S-VOLs, delete them.
The following is an example of creating pairs of different configurations simultaneously. In this
example, one pair of two S-VOLs and another pair of one S-VOL are created simultaneously.
