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).

Use the Pairresync window (see
and suspended BC pairs. When the pairresync operation starts, the pair status changes to COPY(RS) or
COPY(RS-R). When the pairresync is complete, the pair status changes to PAIR. The disk array resumes BC
update copy operations after the pair status changes to PAIR. The P-VOL remains fully accessible during a
normal pairresync operation, but becomes inaccessible to all hosts during a reverse or quick restore
pairresync operation. This ensures that data on the P-VOL is identical to data on the S-VOL when the
reverse or quick restore pairresync operation completes.
