multiple 400's on a single media library

Hi All,

    Until recently our shop operated on a model S20 AS/400. We are in
the process at this moment of bringing a model 640 on along with the
S20. We are using a Magstar 3570 model B12 tape drive with a media
library running out of BRMS. Is it possible to run both systems on the
same tape unit with having to dedicate a single drive to each machine.
if possible I would rather have both systems share both drives. If this
is possible, HOW. Any advice or directions at were to look would be
greatly appreciated.

Thanks in advance,
Chad Walsingham
