Removing broken SnapMirror relationships

If you have managed SnapMirror relationships on a NetApp SAN you no doubt encountered problems deleting them after they have been broken off. One command I have found that resolves this if FilerView will not work is:

snapmirror release source { filer:volume | filer:qtree }

Tell snapmirror that a certain direct mirror is no longer going to request updates. If a certain destination is no longer going you request updates, you must tell SnapMirror so that it will no longer retain a snapshot for that destination. This command will remove snapshots that are no longer needed for replication and can be used to clean up SnapMirror created snapshots after snapmirror break is issued on the destination side.

I find I have to use this command every so often to clean up my snapmirror configs.
