The VOLUME option suspends an XRC volume pair that encounters a
device error. XRC continues to process all other volume pairs in the
XRC session. You must correct the volume’s error condition and
then resynchronize it so that it is consistent with the other volumes
in the XRC session.
If you select VOLUME and the error is associated with the XRC
session, then XRC suspends all volume pairs for that storage control.
Volume processing continues for other storage controls.
Note: If
a volume that is suspended due to an error contains data that is dependent
on data on another volume, data consistency cannot be assured in the
event of a disaster recovery.
