How does TSM handle files that are larger then the tape size? 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:

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.
