And the way to stop it is to set a MAXSCRATCH value for the storage pool.
That will make ADSM collocate the data (i.e., put all today's incoming data
for a client on the same tape it used yesterday for that client), but will
use the same tape for 2 or more clients.  It's the way to go if you have
high capacity tapes, and many small clients.

I forget how you were doing your offsite tape rotation.
Are ANY tapes coming back onsite?

Also look at your volhistory:  q volhist type=DBB
and see how many tapes are being used for DB backups.
