You cannot select a volume in COPY or PAIR status as a source volume.

In a 3DC multi-target configuration with Universal Replicator and TrueCopy, if you create a Universal Replicator pair for a delta resync operation, 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 3DC multi-target configuration is as shown in the tables given below.
