Replication images If any replication images exist for this volume, when you select the Replication Images component, the Replication Images table shows information about each image. For the selected image, the Replication Images table shows: • Image Serial Number. Replication image serial number. • Image Name. User-defined name assigned to the primary replication image. • Snapshot Serial Number. Replication snapshot serial number associated with the image. The replication snapshot is associated with the replication volume specified in the request. • Snapshot Name. Replication snapshot name associated with the image. For a secondary replication image, this value is not filled in until the replication is completed. • Creation Date/Time. Date and time when the replication image was created on the replication volume. 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" (page 29). 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. • Source Volume. 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. • 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.
