Ok, so where are you pulling that from? sv_backup03?
If that's the case if you try to delete that snap it will say it's busy right?
If that's the case, one of the only ways I was able to get past this transitioning snap was to do a takeover and giveback of the cluster or a reboot if its standalone. Once that's done, it will release the *lock* on that snap and you should be able to delete it.
