I had already files split over 3 DLT tapes and it is very common to have files split over 2 tapes.
Looks like you had another problem maybe with tape drives or drivers. You may want to turn tsm tracing on to learn in detail about tape I/O�s causing ANR8301E.

I have a DB2 dump file that is 240GB that I am backing up as a flat file. I can get it into the disk pool without a problem, but I can't seem to get it to migrate to tape, a few small files move and then it seems to work on the large file for an hour or two, and then spit the tape out but not move any data. A little info about my setup: TSM 5.2.2 on Solaris 8 IBM 3494 Library with 3590E tape drives I am using IBM "K" tapes that are 80GB uncompress and somewhere around 120-140Gb compressed. From the actlog: 03/02/04 07:12:48 ANR8341I End-of-volume reached for 3590 volume 2C0448. (PROCESS: 4) 03/02/04 07:12:49 ANR0515I Process 4 closed volume 2C0448.

(PROCESS: 4) 03/02/04 07:12:54 ANR1405W Scratch volume mount request denied - no scratch I added a few scratch tapes and it just seems to go through the same process: 1. Grab the scratch and load it for migration 2. Write to it for awhile: 5 Migration Disk Storage Pool BACKUPPOOL, Moved Files: 19, Moved Bytes: 20,480, Unreadable Files: 0, Unreadable Bytes: 0. Current Physical File (bytes): 211,758,833,664 Current output volume: 2C0448. 3. Error out with ANR8301E I/O error on library IDS02ATL1 (OP=004C6D31,SENSE=00.00.00.67). 4. Remove the tape from the prime pool and back to scratch 5. Repeat the cycle. This is a new server that I have setup so I might have something set wrong though I didn't have any problems running a DB backup to tape.
