HP XP P9000 Auto LUN User Guide (AV400-96606, January 2014)

Auto LUN with Business Copy Z or Business Copy
You can use the Business Copy Z pair volumes or the Business Copy Z pair volumes as the Auto
LUN source volume, excluding the volumes having some pair statuses or the configurations. For
more information, see “Supported and prohibited source and target volumes” (page 11).
CAUTION:
• If you do the Business Copy operation so that the Business Copy pair status becomes COPY
(SP) or PSUS(SP) when Auto LUN and Business Copy share a volume, the Auto LUN process
stops.
• If you do the Business Copy Z operation so that the Business Copy Z pair status becomes other
than SP-Pend or V-Split when Auto LUN and Business Copy Z share a volume, the Auto LUN
process stops.
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 using two mirrors in a 3DC multi-target configuration, cascade configuration, or delta
resync configuration with three Continuous Access Journal sites, as a source volume.
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 18) and Table 9 (page
19).
