Figure 7 Backward Pairresync Operations

Notes:

The P-VOL remains read-enabled during the quick restore operation only to enable the volume

to be recognized by the host. The data on the P-VOL is not guaranteed until the quick restore

operation is complete and the status changes to PAIR.

During reverse or quick restore pairresync, you cannot perform paircreate, pairsplit, or pairresync

for any other pair that shares the same P-VOL (pairsplit-S and pairsplit-E are allowed).
