Yup. I know but the weird thing is, all the backup from this machine goes to
a disk pool, not a tape pool.  The data only gets migrated to tape if the
diskpool gets full... but max tape mounts for the secondary storage pool is
defined on the TSM.  Plus there were no errors on the TSM activity log on
max tape mounts reached nor was there an error on lack of scratch tapes.

Any ideas about what could be the problem is welcome.
