• VOL: Identifies the volumes in the local storage system.

A device ID ending in # (for example, 00:00:3C #)

indicates the LDEV is an external volume. For details on

an external volume, see the HP XP24000/XP20000

External Storage Software User Guide.

A device ID ending in X (for example, 00:00:3C X)

indicates the LDEV is an XP Thin Provisioning virtual

volume. For details on a virtual volume, see the HP

XP24000/XP20000 Thin Provisioning Software User

Guide.

When the initial copy is started by a paircreate

operation, the volume status changes to COPY.

COPY: The 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: The pair has been split by the

user (pairsplit-r), or the pair has been

released by the user from the secondary

storage system (pairsplit-S). The primary

data volume and the secondary data

volume are not synchronized.

PSUE: The pair has been split by the

primary storage system or the secondary

storage system due to an error or a

failure. The primary data volume and

the secondary data volume are not

synchronized.

Suspending: The primary data

volume and the secondary data volume
