Thanks for your suggestions.

Yes, I had available drives.  The only other process using a drive was a DB 
backup.

Yes, the disk pool is shared and was full enough that the 5G would not fit, so 
that explains the tape mount attempt.  But I can still find no reason for the 
job to fail.  We do have plenty of scratch tapes available.  There were no 
errors related to tape problems or other problems during the 4 to 5 minutes 
this backup was trying to run.  I have forced migration of the storage pool.  
It was only about half full, so had not triggered a migration yet.  The backup 
seems to be running to the storage pool ok.

This pool is not collocated, but we have seen backups wait for a tape being 
used by migration when the storage pool was migrating for a collocated pool.

The last comment in your note 

>>you allow client backups to tape drives (a setting I believe...)?

does trigger an idea.  We have recently seen a problem with some Novell backups 
of large files that tried to go to tape.  They appeared to fail because the 
MAXNUMMP setting apparently came in with our upgrade to 3.7, but existing nodes 
got set with MAXNUMMP=0 instead of the default of 1.  They failed with ANS1312E 
error that clearly referenced the MAXNUMMP setting.  I'm wondering if this 
problem is the Unix client version.  This client is an existing AIX client that 
also was left with the MAXNUMMP=0 after the upgrade.

        Do you have available tape drives at that time (it appears that your
are going straight to tape). IF you are not going straight to tape, the DISK

        area that you are trying to backup to can't hold your 5+GB file.
Mind you, that if the DISK pool is shared...it could be some percent full
from other
        backups? Another thought..colocation on?...tape in use by another
process (it shouldn't matter...but...)...available scratch tapes?
        FYI Thanks Tim
        you allow client backups to tape drives (a setting I believe...)?
