NOTE:
Make sure you have either existing repositories, enough free capacity nodes, or available unconfigured capacity for
the storage array on which you are creating the snapshot group repository, otherwise you cannot create the repository and
an error message is displayed.

The system takes a copy of the associated base virtual disk. The snapshot image and its properties are displayed in the navigation tree
for the associated base virtual disk.
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 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.
