Try the export node preview=yes using the syntax for export to media, not the 
export for server-to-server.
Don't know why the difference, but doing it that way doesn't trigger the 
mounts.  (I don't understand why doing it the server-to-server way DOES trigger 
mounts with PREVIEW=YES).

Subject: [ADSM-L] How much active data?

COPY ACTIVE has a preview option to tell me which volumes I'd need, but is 
there a simple way to compute how active data I have? QUERY OCCUPANCY doesn't 
have a useful parameter for that. For some reason, EXPORT NODE tries to mount 
each volume, even with PREVIEW=YES, which doesn't help me -- I'm investigating 
ACTIVE pools precisely because I can't fit my tapes in my library!

I'd like to avoid SELECT commands against BACKUPS or CONTENTS.

Thanks,
Nick
