The Resync Type list allows you to select the pairresync type for the pairs being resynchronized
(from Normal Copy(P->S), Quick Resync(P->S), Reverse Copy(S->P), or Quick Restore(S->P)).
Remember that you must select either Normal Copy(P->S) or Quick Resync(P->S) if the selected
pair is L2 pair or its status is PSUE. Before selecting Reverse Copy(S->P) or Quick Restore(S->P),
make sure that the pair you are going to select meets the following requirements:
Table 37 Requirements for Reverse Copy(S->P) or Quick Restore(S->P) Pairresync Operations

The specified pair must be in the PSUS state. All other pairs that share the same
P-VOL as the specified pair must also be in the PSUS or PSUE state. Pair status
Whether you can execute a quick restore command to a pair that consists of VLL
and normal volumes depends on the volume emulation type. For details, see
Table 38 (page 83) .
