It's late and it's long ago, but I seem to remember something about these mount point and resourceutil things in the line of:
Resource 4, # mountpoint - 1 admin session - 1 mountpoint for diskpools - 2 mountpoint max for tape mounts So in you case, going directly to tape, you will get a max of 3 mountpoints (because there is no diskpool) to tape.

Howard, But resourceutilization is 4 now. It should give me fewer mount points, not more. So why I am overrunning the client's maximum mount points of 2 when resourceutilization is 4? The reason I can't just increase the client's maximum mount points until the message goes away is that there is a maximum of 64 virtual tape drives, so I can't have every client grabbing 4 virtual tapes drives at once. There is also no reason to have all these small clients mounting multiple tape drives at once, since most of them don't have much data or take long to back up. I also just have this concept in my head that TSM is designed according to logical rules, and works as designed. So if it is not behaving the way I think it will, perhaps I don't understand the rules properly, and I need to fix my understanding. Best Regards, John D.

Either increase the maximum allowed mountpoints or put a line in the client DSM.OPT along the lines of resourceutilization 5 (5 works well with 2 mountpoints allowed) See Ya' Howard > -----Original Message----- > From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf > Of Schneider, John > Sent: Wednesday, September 10, 2008 10:35 AM > To: ADSM-L@VM.MARIST.EDU > Subject: [ADSM-L] How does VCB backups handle resource utilization? > > Greetings, > We are running TSM 5.4.3.0 server on AIX 5.3ML5.
