Note*1:
SSWS is a status of Continuous Access Journal pairs. Continuous Access pairs will not change
to SSWS status.
Note*2:
When you restore the XP Snapshot pair whose P-VOL is used as a Continuous Access or
Continuous Access Journal S-VOL, you need to switch operations from the local site to the remote site by
executing the horctakeover command.
The relationship between the XP Snapshot pair status and Continuous Access or Continuous Access
Journal operations is to be as shown in
