Deleting snapshot image

Use the Delete Snapshot Image option to delete the oldest snapshot image from a snapshot group or consistency group.

After a snapshot image is deleted from a snapshot group, the system performs the following actions:
  • Deletes the snapshot image from the storage array.
  • Releases the repository’s reserve space for reuse within the snapshot group.
  • Disables all the associated snapshot virtual disks that exist for the deleted snapshot image.
For a consistency group you can delete:
  • A single snapshot image.
  • Multiple snapshot images that have the same sequence number and creation timestamp.
When a snapshot image is deleted from a consistency group, the system performs the following actions:
  • Deletes the snapshot image from the storage array.
  • Releases the repository’s reserve space for reuse within the consistency group.
  • Moves any member virtual disk, associated with one or more deleted snapshot images, to a Stopped state.
  • Disables the member snapshot virtual disks associated with one or more deleted snapshot images.

To delete the snapshot image, do the following:

  1. From the AMW, select the Storage & Copy Services tab.
  2. Select the snapshot image that you want to delete from the snapshot group or consistency group and then select one of the following menu paths to delete the snapshot image:
    • Copy Services > Snapshot Image > Delete.
    • Copy Services > Consistency Group > Consistency Group Snapshot Image > Delete.
    The Confirm Delete window is displayed.
  3. Type yes in the text box and then click Delete to delete the snapshot image.
