Access Journal pairs. Volumes that are assigned to Continuous Access Journal pairs can be
protected by LUN Manager.
•
Continuous Access Journal S-VOLs cannot be accessed by any UNIX® or PC server host except
when the pair is split.
Resource Partition
You can specify Resource Partition volumes as Cnt Ac-J P-VOL and S-VOL as long as they belong
to the same resource group. For journal volumes, use a Res Par OPEN-V virtual volume.

Fast Snap
Continuous Access Journal pair volumes can be shared with Fast Snap (FS) P-VOLs; however, there
are limitations on how they can be used together.
•
A Cnt Ac-J P-VOL or S-VOL can be used as the FS P-VOL.
•
A Cnt Ac-J P-VOL or S-VOL that is part of a delta resync configuration with Continuous Access
Synchronous can also be used as a FS P-VOL.
•
A FS P-VOL can be used as a Cnt Ac-J S-VOL that is in a single Cnt Ac-J pair or part of a delta
resync configuration; but the Cnt Ac-J pair must be created first.
Configurations with FS volumes
