Dale, I didn't notice any replies, so here goes. My environment is not the same as yours but I also had very old clients to deal with.
My 5.1.7.0 server on AIX 4.3.3 ML-11 has been very stable with most "errors" being just annoyances. No failed sessions or processes; no data lost. Prior to the upgrade from 4.1, I had lots of 3.1.0.6 and 3.1.0.8 Windows and AIX clients, along with 3.1.0.7 Irix clients. That combo mostly worked OK with just a few rare problems. When running a small, simple test system, 3.1 clients worked fine with 5.1 server. Once we upgraded the production TSM system to 5.1, if a 3.1 node had been configured to use a 4.x feature, those 3.1 clients failed to perform backups at all. In particular, we used the DIRMC feature and that seemed to cause the most problems between 3.1 clients and 5.1 server. We did not seriously pursue a fix since we had only 13 current clients on 3.1, and client upgrades were included in the upgrade project. So the answer, from my experience, is to keep the 3.1 client configuration - on both ends of the wire - as simple as possible. Hope this helps.

The server is on AIX 5.1 ML3. Two Questions: 1.) Is TSM server level 5.1.7.2 reliable? 2.) I have two old NetWare clients at the V3.1.0.5 level and two AIX clients at the V3.1.0.6 level. These clients can't be upgraded because of OS levels. Will these old clients continue to work after the server upgrade? Thanks in advance for any comments or advice. Dale Gieseke TSM administrator
