In your situation you can *only* get a true view of things, including
snapshot reserve space and all the rest of it by using the netapp storage
level tools. smo doesn't give you that info. Time to either make good
friends with the storage guys or become a DBA 2.0 (in the original sense)
and bring netapp storage into your realm and skillset. Good luck with
either. Incidentally your Unix admins likely *also* can't see the true
picture unless they are the storage admin as well.
