Hi,

We have moved from os/390 to AIX and for us it has been a very good
experience! only pro's.

OS/390 was used for much more then only TSM so we had all kinds of resource
problems. CPU especially and also tape units. We had one LPAR (of eight
LPARS) with two TSM servers and around 400 clients backing up, so for the
housekeeping of the servers did not have enough units. We now have two NSM's
with a LTO library dedicated for the backups and restores and that is
running without problems.

regards,
