File size limitation question

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,

                                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.
