Auto LUN and Continuous Access Journal

You cannot select a volume in COPY or PAIR status as a source volume. Also you cannot select a
volume where two mirrors are registered in a 3DC multi-target configuration, cascade configuration,
or delta resync configuration with three Continuous Access Journal sites.

In a 3DC multi-target configuration with Continuous Access Journal and Continuous Access
Synchronous, if you create a Continuous Access Journal 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 3 DC multi-target configuration is as shown in

Table 8 (page 17)

and

Table 9 (page

18)

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