Hi,
Server AIX 5.1, TSM 5.2.3 Client AIX 5.1, TSM 5.1.6 (several different machines)
We've been experiencing a number of client errors, which seem to be related to tape mounts taking too long. It appears that tape mounts taking longer than 15 minutes produce the error, but waits less than 15 minutes don't. The server activity log doesn't seem to recognize a problem, other than terminating the lost session "IdleTimeOut" minutes after the client considers the session lost. The backup recovers successfully, but the errors are irritating.
The client isn't behind a firewall, so that doesn't appear to be the problem. Any ideas on why a mount would timeout after 15 minutes? Is there a client parameter that I'm missing?
