“XP Snapshot Operations for Shared XP Snapshot P-VOL/XP Continuous Access or XP Continuous
Access Journal P-VOL” (page 30)
and “XP Snapshot Operations for Shared XP Snapshot P-VOL/XP
Continuous Access or XP Continuous Access Journal S-VOL” (page 30) show the relationship
between the XP Continuous Access or XP Continuous Access Journal pair status and XP Snapshot
operations when the XP Snapshot P-VOL is shared with an XP Continuous Access or XP Continuous
Access Journal volume.
“XP Continuous Access / XP Continuous Access Journal Operations for Shared XP Snapshot
P-VOL/XP Continuous Access or XP Continuous Access Journal P-VOL” (page 31)
and “XP Continuous
Access/XP Continuous Access Journal Operations for Shared XP Snapshot P-VOL/XP Continuous
Access or XP Continuous Access Journal S-VOL” (page 31)
show the relationship between the XP
Snapshot pair status and XP Continuous Access or XP Continuous Access Journal operations for
shared volumes.
If a volume uses two mirrors in the 3DC multi-target configuration, the 3DC cascade configuration,
or the delta resync configuration consisting of three XP Continuous Access Journal sites, the volume
cannot be used as an XP Snapshot pair volume.
For detailed information about XP Continuous Access pair status and operations, see the HP
StorageWorks XP24000/XP20000 Continuous Access Software User Guide. For detailed
information about XP Continuous Access Journal pair status and operations, see the HP
