I forgot to include a message the user found in his OS log files (or whatever they are called under Windows). Please allow me to correct my mistake. This is the error the user found: Event Type:Error Event Source:tsmlvsa Event Category:None Event ID:29 Date:3-11-2005 Time:4:00:09 User:N/A Computer:BGS-242-20 Description: Encountered exception [C005] during copy-on-write operation.

The poster of the original question had a TSM server which was utilizing default timeout values - which are far too low for real world conditions, where clients have to spend a lot of time rummaging around in file systems seeking backup candidates before they next interact with the server. The server may deem such sessions hopeless and terminate them from its end, where sometimes the client "doesn't get the message" that the session was cut off. In all "hang" situations, you need to dig in and extract the details: most "hang" situations are not hangs at all, but peer situations where one side is busy and the other is waiting for it. Look for ANR messages in your TSM server activity log, any OS or dsmerror.log entries on the client, monitor process activity, I/O activity, etc. to ascertain what's really going on. You *may* have a situation that an APAR may cure, but you first need to identify symptoms so as to apply the right remedy. A W2K system which is downlevel in service packs can be the cause of their own problems. Richard Sims
Re: Backup hangs the Windows 2000 server client
Hi, We also have a number of Windows 2000 clients (5.3.2.0) that seem to hang the entire system during a backup. The client has to be rebooted to get it working again. I searched the web and found APAR IC47248 which suggested there is a problem with the TSM Logical Volume Snapshot Agent. Since the client was using Open File Support I asked the user to de-install the LVSA (thereby disabling OFS). I haven't heard from the user since then so I assume that solved the problem.

Backup hangs the Windows 2000 server client
Dear All, I m using TSM server 5.2.2 on Windows 2003 using Library LTO 3582. I take incremental backups daily for all the servers including another windows 2000 server. One of my servers which is IBM 346 running latest secutiy and OS patches hangs and hangs forever untill power button is pressed. the system always hangs and the process of backup restarts and hangs again and again. there is no specific point or file where it hangs. also the TSM server logs show that the session was idle and was terminated. Mount retention expires and tape is safely put back into its slot. I am using open file backup support with include.fs. I m stuck ! Please help.
