Figure 4 3DC multi-target configuration
Table 8 Pair status when primary volume of Continuous Access Journal delta resync pair is a source
volume
Status Pair Name
PSUS or PAIR Continuous Access Synchronous pair
Any pair status can be acceptable Continuous Access Journal pair
HOLD or HLDE Continuous Access Journal pair for delta resync operation
Table 9 Pair status when secondary volume of Continuous Access Journal delta resync pair is a
source volume
Status Pair Name
Any pair status can be acceptable Continuous Access Synchronous pair
PSUS Continuous Access Journal pair
HOLD or HLDE Continuous Access Journal pair for delta resync operation
Also, the source and target volumes must belong to the same CLPR.
CAUTION: 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.
Volumes having access attribute of Data Retention
You can select a volume setting an access attribute by using Data Retention as a source volume.
However, depending on the access attribute of the target volume, you may not be able to perform
the Auto LUN operations. For the information about whether or not you can perform the volume
migration operation to the volume having the access attribute of Data Retention, see
Table 10 (page
17) .
