Table 6

shows the requirements for reverse and quick restore pairresync operations. If you perform

these operations on pairs that do not fulfill the requirements, the reverse copy or quick restore command
is rejected.

Table 6 Requirements for reverse or quick restore pairresync operations

Requirements

Parameter

The specified pair must be in the PSUS state. All other pairs sharing 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 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).
