As a precaution I run a daily report that does "backup stg tapepool
copypool preview=volume wait=yes" for each of my storage pools.   This
way I will know if anything snuck out of the diskpool to the tapepool
prior to backing it up to a copypool.

Just wanted to pass that on in case someone didn't know how to check
that their tapepool and copypool were in sync.

As I recently learned, TSM tries to reserve space on disk for the
largest file it's going to backup in the current session.  If there is
not space for that file on disk, it, and the whole backup, will go
directly to tape.  And it certainly appears as if all subsequent backups
from all other nodes will go to tape as long as there are any active
sessions.
