virtual disk that is a member of the consistency group before creating the snapshot images. If thesnapshot image cannot be completed successfully for all of the consistency group members, thiscommand fails and new snapshot images are not created.Since all members of a snapshot consistency group normally contain the same number of snapshotimages, adding a new member to a snapshot consistency group with this command create a newmember lacking previously created snapshot images. This is not an indication of an error condition.To create a consistency group snapshot image:create cgSnapImage consistencyGroup="consistencyGroupName"where, consistencyGroup is the name of the consistency group for which you are creating snapshotimages.Deleting A Snapshot Virtual Disk Or A Consistency Group Snapshot VirtualDiskYou can use the following command to delete a snapshot virtual disk or a consistency group snapshotvirtual disk. Optionally, you can also delete the repository members.delete cgSnapVirtualDisk ["snapVirtualDiskName"] [deleteRepositoryMembers=(TRUE| FALSE)];where, snapVirtualDiskName is the snapshot you want to delete. ThedeleteRepositoryMembers=TRUE parameter will preserve the member virtual disks (default). Settingthe parameter to FALSE will delete the member virtual disks.Deleting A Consistency Group Snapshot ImageYou can delete the snapshot images in a consistency group. However, when you delete a consistencygroup snapshot image that is associated with a consistency group snapshot virtual disk, thecorresponding snapshot virtual disk member in the consistency group snapshot virtual disk is transitionedto a Stopped state. Being in this state means that the snapshot virtual disk member no longer has arelationship to the snapshot group of the deleted snapshot image. A snapshot virtual disk member in aStopped state maintains its relationship to its consistency group snapshot virtual disk.When a snapshot image(s) is deleted from a consistency group:• The snapshot is deleted from the storage array.• The repository’s reserve space for reuse within the consistency group is released.• Any member virtual disk associated with the deleted snapshot image(s) is moved to a Stopped state.• The member snapshot virtual disks associated with the deleted snapshot image(s) is deleted.To delete two snapshot images named all_data_1 from a consistency group, use the followingcommand:delete cgSnapImage consistencyGroup="all_data_1"To succeed, all snapshot images must be deleted or the command will fail and no snapshots will bedeleted.Scheduling Snapshot ImagesUsing the enableSchedule and schedule parameters with virtual disk and consistency groupcommands, you can schedule regular snapshot images to recover files or schedule regular backups. Theschedule can be set when you initially create a snapshot group or consistency group, or you can add itlater to an existing snapshot group or consistency group.56
