Type
•
standard
: Standard volume.
•
standard*
: Destination of an in-progress volume copy and cannot be
mounted/presented/mapped until the copy is complete.
•
snap-pool
: Snap-pool volume.
•
master volume
: Master volume.
•
snapshot
: Snapshot volume.
•
replication source
: Source for an in-progress replication to a secondary volume.
•
unknown
: Unknown
Class
•
standard
: Standard volume, not enabled for snapshots.
•
PTSNAP
: Snapshot-related volume such as a master volume, snap pool, or snapshot.
•
Proxy
: Destination of an in-progress replication from a remote volume, which when complete
will change to type
snapshot
Qualifier
•
N/A
: Non-replication-specific volume such as a standard volume, master volume, snapshot, or
snap pool.
•
RSR
: Replication-specific volume, such as a primary volume, secondary volume, replication
snapshot, or replication image.
•
RSR (DRM Promoted Secondary)
: During an actual site failover (not a test failover), the
replication set's primary and secondary volumes are shown as primary volumes with a
primary-volume conflict. This qualifier enables host-based Storage Replication Adapter (SRA)
software to determine which volume is the failed-over secondary volume for disaster recovery
management (DRM). If both systems are online and the communication link between them is up,
both systems will show similar information. When the SRA completes a restore-replication or
reverse-replication operation, this volume will be shown as a secondary volume with the
RSR
qualifier.
Volume Description
•
For OpenVMS, a numeric value (set with
create volume
or
set volume
) that identifies the volume
to an OpenVMS host.
•
For HP-UX, a text value (set in-band by a host application) that identifies the volume.
•
Blank if not set.
WWN
World Wide Name of the volume, used by host-based Storage Replication Adapter (SRA) software
to identify the volume.
