Media servers never share tapes with eachother. If you really want
them on the same tape, you could use bpduplicate to duplicate the
images onto one tape and then expire the original tapes. This assumes
you have at least 2 drives, or a disk storage unit large enough to
hold the images temporarily (duplicate to the disk unit, duplicate
back off to tape)
