volume-type string • standard: Standard volume.
• standard*: Destination of an in-progress volume copy and cannot be
mounted 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
volume-type-
numeric
string Numeric equivalents for volume-type values.
• 0: standard
• 1: snap-pool
• 2: master volume
• 3: snapshot
• 4: standard*
• 8: replication source
volume-class string • 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.
volume-class-
numeric
string Numeric equivalents for volume-class values.
• 0: standard
• 1: PTSNAP
• 3: Proxy
volume-
qualifier
string
• 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 with the RSR qualifier.
