Problem:
How do I delete a busy NetApp storage snapshot left behind from an unsuccessful Veeam Storage snapshot backup?
Solution:
1. Set the privilege mode
set -privilege advanced
2. Show the volume you want to remove
lun show -vserver crp_svm -volume VeeamAUX_crp_vol01_Backup
3. Show the volume the the flexclone is taken from
lun show -vserver crp_svm -volume crp_vol01
4. Take the volume to be deleted offline:
vol offline -vserver crp_svm -volume VeeamAUX_crp_vol01_Backup
5. Delete the volume
vol delete -vserver crp_svm -volume VeeamAUX_crp_vol01_Backup
6. Go into the GUI and delete the snapshot
