110 Viewing system status
• SharedData. The amount of data that is potentially shared with other snapshots and the associated amount of
space that will be freed if the snapshot is deleted. This represents the amount of data written directly to the
snapshot. It also includes data copied from the source volume to the storage area for the oldest snapshot, since
that snapshot does not share data with any other snapshot. For a snapshot that is not the oldest, if the modified
data is deleted or if it had never been written to, this value is zero bytes.
• Priority. Retention priority for the snapshot, based on the snapshot attributes and the user-defined priority for the
snapshot type.
• User Priority. User-defined priority for the snapshot type.
• Type.
• Standard snapshot: Snapshot of a master volume that consumes a snapshot license.
• Standard snapshot (DRM): A temporary standard snapshot created from a replication snapshot for the
purpose of doing a test failover for disaster recovery management (DRM).
• Replication snapshot: For a primary or secondary volume, a snapshot that was created by a replication
operation but is not a sync point.
• Replication snapshot (Replicating): For a primary volume, a snapshot that is being replicated to a secondary
system.
• Replication snapshot (Current sync point): For a primary or secondary volume, the latest snapshot that is
copy-complete on any secondary system in the replication set.
• Replication snapshot (Common sync point): For a primary or secondary volume, the latest snapshot that is
copy-complete on all secondary systems in the replication set.
• Replication snapshot (Old Common sync point): For a primary or secondary volume, a common sync point
that has been superseded by a new common sync point.
• Replication snapshot (Only sync point): For a primary or secondary volume, the only snapshot that is
copy-complete on any secondary system in the replication set.
• Replication snapshot (Queued): For a primary volume, a snapshot associated with a replication operation that
is waiting for a previous replication operation to complete.
• Replication snapshot (Awaiting replicate): For a primary volume, a snapshot that is waiting to be replicated to
a secondary system.
Mapping properties
When you select the Maps component, the Maps for Volume table shows:
• Type. Explicit or Default. Settings for an explicit mapping override the default mapping.
• Host ID. WWPN or IQN.
• Name. Host name.
• Ports. Controller host ports through which the volume is mapped to the host.
• LUN. Volume identifier presented to the host.
• Access. Volume access type: read-write, read-only, no-access (masked), or not-mapped.
Schedule properties
If any schedules exist for the snapshot, when you select the Schedules component, the Schedules table shows
information about each schedule. For the selected schedule, the Schedule Details table shows:
• Schedule Name.
• Schedule Specification.
• Schedule Status.
• Next Time.
• Task Type.
• Task Status.
• Task State.
• Source Volume.
• Source Volume Serial.
