Also, the source and target volumes must belong to the same CLPR.

If you create a Continuous Access Journal Z pair for a delta resync operation in a 3DC multi-target
configuration, the primary volume or the secondary volume of the delta resync pair can be used
as a source volume. To use the primary or secondary volume as a source volume, you must ensure
that the status of each pair in the 3 DC multi-target configuration is as shown in

Table 6 (page 16)

and

Table 7 (page 17)
