RequirementsParameter
Whether you can execute a quick restore command for a pair consisting of
customized and normal volumes depends on the volume's emulation type.
Pair type
If BC and Continuous Access XP pairs share the same volume, and the Con-
tinuous Access XP pair is not suspended, you cannot perform reverse and
quick restore pairresync operations.
Shared BC/Continuous Access
XP volume
If the BC and Continuous Access XP Journal pairs share the same volume,
and the Continuous Access XP Journal pair is not suspended, you cannot
perform the reverse and quick restore pairresync operations.
Shared BC/Continuous Access
XP Journal volume
NOTE:
A Continuous Access XP Journal P-VOL means a Continuous Access XP Journal primary data volume.
A Continuous Access XP Journal S-VOL means a Continuous Access XP Journal secondary data
volume.
CAUTION:
If a reverse or quick restore resync operation ends abnormally, or a Pairsplit-E (PSUE) is requested
during a reverse or quick restore resync operation, the status of other BC pairs sharing the same
P-VOL does not change.
NOTE:
When a reverse or quick restore pairresync operation is in progress, you cannot perform paircreate,
pairsplit, or pairresync operations for any other pairs sharing the same P-VOL (pairsplit-S and
pairsplit-E are allowed).
