Canceling A Pending Snapshot Image

Use the Cancel Pending Snapshot Image option to cancel a snapshot image that was put in a Pending
state when you attempted to create the snapshot image for either a snapshot group or a consistency

group.

The snapshot image is in a Pending state due to the following concurrent conditions:

• The base virtual disk for a snapshot group or one or more member virtual disks of a consistency group

that contains this snapshot image is a member of an asynchronous remote replication group.

• The virtual disk or virtual disks are currently in a synchronizing operation.

The snapshot image creation operation completes as soon as the synchronization operation is complete.
To cancel the pending snapshot image creation before the synchronization operation completes, do the
following:

1.

From the AMW, select either the snapshot group or consistency group that contains the pending

snapshot image.

2. Do one of the following:

– Copy Services → Snapshot Group → Advanced → Cancel Pending Snapshot Image.
– Copy Services → Consistency Group → Advanced → Cancel Pending Consistency Group

Snapshot Image.

Deleting A 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(s) 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 the deleted snapshot image(s), to a Stopped state.
• Disables the member snapshot virtual disks associated with the deleted snapshot image(s).
