John,

we upgraded our ADSM server to V3 (on AIX 4.1) 4 weeks ago; the HSM client
is still at 2.1.0.7 (on AIX 4.1, server and client are running on the same
machine). We did not encounter any problems in the HSM area. Perhaps I
should say, that access to our HSM file system is restricted to FTP; it
thus is not that highly active, although there are lots of data in it
(180 GB).

I would be interested to hear about your reasons to abandon HSM ...
