Pair status values
When checking pair status in RWC, click File/Refresh to verify that the data is current.
In RWC, the pair status is shown in the [pair status in Remote Web Console/pair
status in RAID Manager]
format. If the pair status name in RWC and the pair status name
in RAID Manager are the same, the pair status name in RAID Manager is not shown.
The following table lists ESAM pair status and whether the volumes can be accessed. The
accessibility to P-VOL or S-VOL depends on the pair status and VOL Access. You can see VOL
Access in the Pair Operation window or the Detailed Information dialog box.
