Dell PowerVault MD3260i - Manual (Page 201)

Parameter Description
snapshot group names in double quotation marks (" ").
Enclose all of the snapshot group names in parenthesizes.
If you do not use any other parameters with the
snapGroup parameter or snapGroups parameter, then
by default the oldest snapshot image is deleted.
deleteCount The number of snapshot images that you want to delete
from the snapshot 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.
If the number that you enter is greater than the actual
number of all of the snapshot images in the snapshot
group, all of the snapshot images will be deleted. The
snapshot group is left empty.
retainCount The number of snapshot images that you want to keep in
the snapshot group. Use integer values. This parameter
keeps the most recent snapshot images in the snapshot
group and deletes older snapshot images.
If the number of existing snapshot images in the snapshot
group is less than the number that you enter, none of the
snapshot images are deleted.
ignoreSnapVirtual Disk Use this parameter to make sure that you do not delete a
snapshot image that has a snapshot virtual disk
associated with the snapshot image. You can use one of
these values:
• TRUE—Use this value to delete the snapshot
image even though the snapshot image has an
associated snapshot virtual disk.
• FALSE—Use this value to keep the snapshot
image when the snapshot image has an
associated snapshot virtual disk.
The default value is TRUE.
snapImageID The snapImageID parameter accepts only the OLDEST
option. This parameter deletes the earliest snapshot
image created.
Notes
You can delete the oldest snapshot image from a snapshot group repository virtual disk. The definition of a snapshot
image that you delete is removed from the system. The space occupied by the snapshot image that you delete from the
snapshot group repository virtual disk is released and made available for reuse within the snapshot group.
Any snapshot virtual disks that exist for a snapshot image transition to the Stopped state when the snapshot image is
deleted.
This command will not run when the controller is in Lockdown mode.
