• Status: Status of volume pairs.

SMPL

The volume is not currently assigned to a pair. When the initial copy is started

by a paircreate operation, the volume status changes to COPY.

COPY

An initial copy operation is in progress. Data in the primary data volume is not

synchronized with data in the secondary data volume. When the initial copy is

complete, the status changes to PAIR.

PAIR

The volume is paired with another volume. The two volumes are fully

synchronized. All updates from the host to the primary data volume are

duplicated at the secondary data volume.

PSUS

You split the pair (pairsplit-r) or deleted the pair from the secondary array

(pairsplit-S). The primary and secondary data volumes are not synchronized.

PSUE

The pair was split by the primary or secondary array due to an error or failure.

The primary and secondary data volumes are not synchronized.

Suspending

The primary and secondary data volumes are not synchronized. This pair is in

transition from the PAIR or COPY status to the PSUS/PSUE status.

Deleting

The primary and secondary data volumes are not synchronized. This pair is in

transition from the PAIR, COPY, or PSUS/PSUE status to the SMPL status.

HOLD

A Continuous Access XP Journal pair for the delta resync operation is created.

HLDE

An error occurred with the Continuous Access XP Journal pair for the delta

resync operation.
