Ok, but aren't the policies you can set on the HSM client such that you
can achieve exactly that? I mean, disk on the client or the server
doesn't really matter most of the time, does it? And TSM policies never
allow you to base migration of diskpool to tapepool on the amount of
time a file hasn't been touched, just on the time the file has bee in
the pool.
