That'd work;  You could also make it an absolute requirement of your
infrastructure to maintain scratch availability, and do new acquisitions
when scratch levels fall below <foo>.

"Me too".


I have a script, which I think I've bandied about here in the past,
which evaluates collocation for me, but I think it's poorly aligned with
your needs, Grant:  I select candidates for inclusion into collocation
groups, and then once that's done I MOVE DATA to vacate tapes which are
low-utilization and have a candidate collocated home.
