Renaming a snapshot group
Use the Rename Snapshot Group option to change the name of the snapshot group when the current name is no longer meaningful or
applicable.
Keep these guidelines in mind when you name a snapshot group:
• A name can consist of letters, numbers, and the special characters underscore (_), hyphen (-), and pound (#). If you choose any other
characters, an error message is displayed. You are prompted to choose another name.
• Limit the name to 30 characters. Any leading and trailing spaces in the name are deleted.
• Use a unique, meaningful name that is easy to understand and remember.
• Avoid arbitrary names or names that would quickly lose their meaning in the future.
• If you try to rename a snapshot group with a name that is already in use by another snapshot group, an error message is displayed, and
you are prompted to choose another name for the group.
To rename a snapshot group:
1. From the AMW, select the Storage & Copy Services tab.
2. Select the snapshot group that you want to rename and then select Copy Services > Snapshot Group > Rename.
The Rename Snapshot Group window is displayed.
3. Type a new name for the snapshot group and then click Rename.
Deleting snapshot group
Use the Delete Snapshot Group option to delete a snapshot group.
The system performs the following actions when a snapshot group is deleted:
• Deletes all existing snapshot images from the snapshot group.
• Deletes the associated repository that exists for the snapshot group—if selected.
• Disables all the associated snapshot virtual disks that exist for the deleted snapshot images.
To delete the snapshot group:
1. From the AMW, select the Storage & Copy Services tab.
2. Select the snapshot group that you want to delete and then select Copy Services > Snapshot Group > Delete.
The Confirm Delete window is displayed.
3. Select Delete all repositories associated with this object? if you want to delete the associated repository that exists for the
snapshot group.
4. Type yes in the text box and then click Delete to delete the snapshot group.
Converting a snapshot Virtual Disk to read-write
Use the Convert Snapshot Virtual Disk to Read-Write option a to convert a read-only snapshot virtual disk to a read-write snapshot
virtual disk.
You can use the Convert Snapshot Virtual Disk to Read-Write option for these storage objects:
• Snapshot virtual disk
• Consistency group member’s snapshot virtual disk
The conversion operation requires that a repository be provisioned to support write operations on the snapshot virtual disk.
1. From the AMW, select the Storage & Copy Services tab.
2. Select either a snapshot virtual disk or a consistency group member’s snapshot virtual disk and then select Copy Services >
Snapshot Virtual disk > Convert to Read-Write.
3. Select how you want to create the repository for the Read-Write snapshot virtual disk. Do one of the following:
• Select Automatic to create the snapshot virtual disk repository with the default capacity settings. This is the recommended
option.
• Select Manual to define the properties for the snapshot virtual disk repository. Use this option if you want to specify all of the
customizable settings for the snapshot virtual disk repository. The Manual method is considered advanced and only those who
understand physical disk consistency and optimal physical disk configurations should use this method.
