How to remove old snapshot in busy state??

[fallen-uk]

Hi,

Have a volume(VOL6) with a very old snapshot called "ll" that is in a "busy,Snapmirror" state and I cannot delete it from OnCommand System Manager. The snap has grown to 4.76TB..., but it will not give me the delete option in the GUI to remove it.

How can I remove it ?

So what happens if you try to delete it from CLI?

[fallen-uk]

nas3> snap delete vol6 ll
Snapshot ll is busy because of snapmirror, sync mirror, volume clone, snap restore, dump, CIFS share, volume copy, ndmp, WORM volume, SIS Clone, LUN clone

The problem is resolved.

nas3:/vol/vol5/data_q12  nas3:/vol/vol6/data_q12  Uninitialized  00:00:00   Idle with restart checkpoint (at 106 MB) - It was a key issue

Snapmirror abort -h nas3:/vol/vol6/data_q12, then snapshot goes to normal mode and i delete it.
