I agree, this level sucks completely. Server crashes at least 3 times a week
with internal errors (APAR IC31884), mount failed problems (if all drives are in
use), and last but not least, after a server restart, most of the private
volumes in the tape library becomes scratch, and scratch volumes becomes
private (APAR IC31691). So what happens is that if TSM asked for a scratch
volume, the Library Manager gives 95% of the time a private volume, thank God
TSM recognise this volume as one of his a private volumes, asked again for a
scratch volume, and on and on and on. So sometimes mount takes for hours. We use
now a script to get the Library manager in sync with the TSM server (i.e. change
the categories with mtlib). And we have a crontab entry which checks if our
server is still running, if not, the server will started.

Btw, the reason we went 2 weeks ago to 4.2.1 was that the 4.1.1 server did hang
at least 5 times a week, so we had to halt the server and restart it everytime
(symtoms were simple queries like q proc never ended, and cancel proc didn't
work at all).
And btw2, we run our "TSM-server" on AIX 4.3.3.0.

Cheers,
Henk (waiting for lot's of fixes)
