Have a volume with a snapshot called exchsnap__apollo_04-15-2011_19.00.13 that is in a "busy,LUNs" state and I cannot delete it from OnCommand System Manager. My guess is it's from SnapManager for Exchange which is no longer installed on the server and being used (there are no other SnapManager snapshots on the volume). The snap has grown to 70GB, but it will not give me the delete option in the GUI to remove it. How can I remove it is SnapManager is no longer around?
