– Select one or more consistency groups, from the Consistency groups table, that you want to remove the
base virtual disk from and then click Remove.
NOTE: You can click the Select all check box to remove the virtual disk from all the consistency
groups displayed in the table.
– Select the member virtual disks, from the Member virtual disks table, that you want to remove from the
consistency group and then click Remove.
NOTE: You can click the Select all check box to remove all the virtual disks displayed in the table.
4. Select the Delete all repositories associated with this member virtual disk if you want to delete all associated
repositories that exist for the member virtual disk(s) in the consistency group.
5. Type yes in the text box and then click Delete to delete the member virtual disk(s) from the consistency group.
The system removes the member virtual disks from the consistency group; they will not be deleted.
Creating A Snapshot Virtual Disk Of A Snapshot Image
You create a snapshot virtual disk to provide host access to a snapshot image within a snapshot group. A read-write
snapshot virtual disk has its own repository that is used to save any subsequent modifications made by the host
application to the base virtual disk without affecting the referenced snapshot image.
The snapshot virtual disk can be designated as either read-only or read-write:
• A read-only snapshot virtual disk provides a host application with READ access to a copy of the data contained
in the snapshot image, but without the ability to modify the snapshot image. A read-only snapshot virtual disk
does not have an associated repository.
• A read-write snapshot virtual disk requires an associated repository to provide the host application with WRITE
access to a copy of the data contained in the snapshot image.
Snapshot Virtual Disk Limitations
• You cannot create a snapshot virtual disk of a Failed base virtual disk.
• Snapshot repositories are fully resizeable. If you have the storage capacity you can increase the size of the
snapshot repository to avoid a repository full message. Conversely, if you find that the snapshot repository is
larger than you need, you can reduce its size to free up space that is needed by other logical virtual disks.
• If you create a snapshot virtual disk for a snapshot image and that snapshot image creation operation remains in
a Pending state it is due to the following conditions:
– The base virtual disk that contains this snapshot image is a member of an asynchronous remote
replication group.
– The base virtual disk is currently in a synchronizing operation. The snapshot image creation will
complete as soon as the synchronization operation is complete.
Creating A Snapshot Virtual Disk
1. From the AMW, select the Storage & Copy Services tab.
2. Do one of the following:
– Select a base virtual disk, and then select Copy Services → Snapshot Virtual disk → Create. The Select
Existing Snapshot Image or New Snapshot Image window is displayed.
– Select a base virtual disk, and then select Copy Services → Snapshot Image → Create Snapshot Virtual
Disk. The Snapshot Virtual Disk Settings window is displayed. Go to step 4.
3. If you selected a base virtual disk in step 1, choose the snapshot image for which you want to create a snapshot
virtual disk. Do one of the following:
