Well, I'm really confused now.

I came up with my own version of the query:

select distinct volume_name,stgpool_name
    from volumeusage
    where node_name='FOO'

and that produces an answer:

VOLUME_NAME            STGPOOL_NAME
------------------     ------------------
ITF010                 CPITFPOOL
ITF010                 CPITFPOOL
ITF013                 CPITFPOOL
ITF018                 CPITFPOOL
ITF026                 CPITFPOOL
ITF001                 ITFPOOL
ITF003                 ITFPOOL
ITF004                 ITFPOOL
ITF014                 ITFPOOL
ITF025                 ITFPOOL
ITF027                 ITFPOOL
ITF028                 CPITFPOOL
ITF006                 ITFPOOL
ITF002                 CPITFPOOL

BUT if I add "order by stgpool_name" it doesn't show all the tapes - eg:

VOLUME_NAME            STGPOOL_NAME
------------------     ------------------
ITF010                 CPITFPOOL
ITF010                 CPITFPOOL
ITF001                 ITFPOOL

So what's going on here?
