Viewing Information About A Snapshot; Snapshot Properties - HP P2000 G3 Reference Manual

• Source Volume Serial. Source volume serial number.
• Destination Vdisk. Name of the destination vdisk for a volume copy.
• Destination Vdisk Serial. Destination vdisk serial number.
• Prefix. Label that identifies snapshots, volume copies, or replication images created by this task.
• Count. Number of snapshots to retain with this prefix. When a new snapshot exceeds this limit, the
oldest snapshot with the same prefix is deleted.
• Last Created. Name of the last snapshot, volume copy, or replication image created by the task.
• Last Used Snapshot. For a task whose replication mode is last-snapshot, the name of the last snapshot
used for replication.
• Snapshot Name. Name of the snapshot to reset.
• Snapshot Serial. Snapshot serial number.
• Mode. Replication mode:
• new-snapshot: Replicate a new snapshot of the primary volume.
• last-snapshot: Replicate the most recent existing snapshot of the primary volume.
For a TakeSnapshot task, the Retained Set table shows the name and serial number of each snapshot that
the task has taken and is retaining.

Snapshot properties

When you select the Snapshot component, the Properties for Snapshot table shows:
Vdisk Name.
•
• Serial Number. Snapshot serial number.
• Name. Snapshot name.
• Creation Date/Time.
• Status.
• Status-Reason.
• Master Volume Name. Name of the volume that the snapshot was taken of.
• Snap-pool Name.
• Snap Data. The total amount of data associated with the specific snapshot (data copied from a source
volume to a snapshot and data written directly to a snapshot).
• UniqueData. The amount of data that has been written to the snapshot since the last snapshot was
taken. If the snapshot has not been written or is deleted, this value is zero bytes.
• 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.
