Backups going to disk Fail without Tape drive online?
Greetings *SM'ers, Environment: Server: Win2K SP2, TSM 5.1.1 Clients: NT4 SP6a TSM 5.1.1 and Win2K SP2, TSM 5.1.1 I am relatively new to TSM, and not afraid of being humbled! Our library failed yesterday and is being repaired today. Last night most (but not all) of the backups failed on the clients with errors like the one below. All clients point to disk pools for their backups and the disk pools are/were online and available. I assumed the backups would continue despite the library not being available, am I wrong to assume this? I understand our migration/reclamation is not possible today until the library is repaired, but we specifically designed our diskpools to be able to handle 3-4 days of backups without migration for this very reason. As is evident by the Pct Migr. Number, the pool took on almost no data during the backups. Simultaneous writes to Copy Pools are disabled as well. I guess I am wondering why TSM needs the tape drive during the backups if the clients point to the disk which has plenty of space and is available? Any help would be greatly appreciated. In all likelihood, this is a PEBCAK problem. :-( In the future, is there a good or graceful way to take a library offline. I know it can be done with the VARY command against disks, but is there a similar option for libraries? snip 08/28/2002 18:00:31 --- SCHEDULEREC STATUS END 08/28/2002 18:00:31 ANS1312E Server media mount not possible 08/28/2002 18:00:31 --- SCHEDULEREC OBJECT END DAILY_INCR 08/28/2002 18:00:00 08/28/2002 18:00:31 ANS1512E Scheduled event 'DAILY_INCR' failed.

Re: Backups going to disk Fail without Tape drive online?
A couple of things to check: - Is anyone using INCLUDE statements to bind files to management classes that go straight to tape? - Check the RETONLY in your copygroup settings. By default, the client will bind directories to the management class with the highest RETONLY value. If more than one class has this high value, then the class whose name is alphanumerically highest will be the one that is used. Maybe you have a copygroup whose destination is tape and whose RETONLY value happens to be the highest.

Re: Backups going to disk Fail without Tape drive online?
A big hats off to all who answered! After sifting through all the answers (which taught me quite a bit more about TSM I might add), it appears Andy nearly hit the nail on the head. The CopyGroup with the longest RETONLY value was a diskpool, BUT it had no volumes defined (yet). Thereby forcing the data (directories in this case) to go downstream to the tape pool which was, obviously, unavailable. Thanx again everyone!!
