Don,
Check
out chapter 5 in the ADSM Administrators Guide - Managing a Full
Library.
Beyond
what it states in the manual, if you've taken the default of 0 for maxscratch
instead of setting maxscratch to the number of tapes in your library, ADSM will
ask for the mount of a new scratch volume after running out of free tapes in
your library. This will come in the form of a request, so you'll want to
have a mount request window running when that happens (dsmadmc -mount). If
you do see the request, export an existing volume and import a new you do see the request, export an existing volume and import a new volume.
The new volume must be pre-labled for ADSM.
If you
have maxscratch set to the number of tapes in the library, you will eventually
receive a Server out of data storage space during a backup when ADSM can't find
enough free space.
You
want to stay ahead of the backups by ensuring that there is enough free space
for backups each day.
Check
the used percentages on your existing tapes and the reclamation thresholds to
see if you can reclaim tapes that are in the library now.
And
budget for a new tape library next year.

We have been running ADSM for nearly 8
months now and things have been running very well. We recently changed some
of the copy group parameters so that we retain more objects longer and our
tape storage is nearing capacity. We are writing only to tape and we have
never had to change a tape out of our 3570. So my question is this; when
ADSM finally fills up that last tape, what will it do? Do I just
define some tapes to the tape library and ADSM will ask for them? I
kind of confused on this point and hoping that someone can give me some
insight.
Thanks in advance!
