Viewing information about a snapshot
In the Configuration View panel, right-click a snapshot and select View > Overview. The Snapshot
Overview table shows:
• The capacity and space usage of the snapshot
• The quantity of mappings for the snapshot
• The quantity of task schedules for the snapshot
For descriptions of storage-space color codes, see About storage-space color codes.
Select a component to see more information about it.
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 0.
• 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 0.
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.
• 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.
