Debbie,
I have a suggestion to give you 6 months on disk, then push to tape.
This will work especially well with file disk. Make multiple stgpools,
for example, march, april, etc. Using a script or schedule, update the archive
destination
to use the current month stgpool. Using another script or schedule, migrate
the pool
6 months later. The file type scratch volumes will be freed and so you will
have only a net of 6 months worth of migrated files stored on
TSM disk.
Thanks,
Bill Colwell

The problem is that to satisfy customer requests for archived data, it has to
stay on disk. Tape retrievals take too long. We would prefer a hierarchical
system that would allow, for example, files not touched in 6 months to go to
disk, then if still not touched for another 6 months they migrate to tape.
With the way this product works we will have to either manually create the
hierarchy, or leave everything on disk. Not much of a savings there. Might as
well just add the extra disk to the file server.

Hi,
I don't agree with you I think it is a more or les a good product, I only
detect a problem " Reconcile Files". But you can backup and restore stub files
from TSM client and you can restore one stub and recall the file from HSM and
you don't need to recall all files. In case you lost a directory with 10000
files you restore the stub files it is more quickly. Other point is you need to
establish a archive copy group with a long retention because you can recall a
file because you have the stub file and this can be expired in the TSM Server.

When I heard about it ( Long Time Ago: Last Oxford ) my comment was that it is
not really like anything that I've seen labeled HSM before.
Previous discussion, last January, starts:

I piped up here:

I think your observations mesh well with mine, though you're looking at it from
a slightly different perspective.
Beware about the "back up the migrated stub file" problem.
