CAUTION:
•
If you do the Continuous Access Synchronous operation so that the Continuous Access
Synchronous pair status becomes other than PSUS when Auto LUN and Continuous Access
Synchronous share a volume, the Auto LUN process stops.
•
If you do the Continuous Access Journal operation so that the Continuous Access Journal pair
status becomes other than PSUS when Auto LUN and Continuous Access Journal share a
volume, the Auto LUN process stops.
Auto LUN and Continuous Access Journal Z
You cannot select a volume in Pending Duplex or Duplex status as a source volume. Also you
cannot select a volume using two mirrors in the 3 DC multi-target configuration or cascade
configuration with three Continuous Access Journal Z sites, as a source volume.
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
and
