Delete Consistency Group Snapshot Image

Description

This command deletes the snapshot images in a consistency group.

Syntax

delete cgSnapImage consistencyGroup="consistencyGroupName" 
                                 [deleteCount=numberOfSnapImages]
                                 [retainCount=numberOfSnapImages]
                                 [ignoreSnapVirtualDisk=(TRUE | FALSE)]

Parameter

Parameter Description
consistencyGroup The name of the consistency group from which you want to delete the snapshot images. Enclose the consistency group name in double quotation marks (" ").
deleteCount The number of snapshot images that you want to delete from the consistency group. Use integer values.

This parameter deletes the oldest snapshot image first and continues to delete the oldest snapshot images until reaching the number that you enter.

retainCount The number of snapshot images that you want to keep in the consistency group. Use integer values. This parameter keeps the most recent snapshot images in the consistency group.
ignoreSnapVirtualDisk Determines whether the associated consistency group snapshot virtual disk is kept or deleted. This parameter applies only if the consistency group snapshot image is associated with a consistency group snapshot virtual disk. To keep the snapshot virtual disk, set this parameter to TRUE. To delete the snapshot virtual disk, set this parameter to FALSE. The default value is FALSE.

Notes

If the snapshot images cannot be deleted for all of the relevant consistency groups, the operation fails and none of the snapshot images are deleted.

When you delete a consistency group snapshot image that is associated with a consistency group snapshot virtual disk, the corresponding snapshot virtual disk member in the consistency group snapshot virtual disk transition to the Stopped state. A snapshot virtual disk member in the Stopped state no longer has a relationship to the snapshot group of the deleted snapshot image. However, a snapshot virtual disk member in the Stopped state keeps its relationship to its consistency group snapshot virtual disk.
