You are correct, the backup should continue to another tape volume.

There are a couple known problems with EOV handling on DLT drives...one of
which was
fixed by updating the firmware on the drive.   Please contact IBM service
for the ADSM server
so that they can help you determine which EOV problem you are seeing.

In the meantime, have you tried turning compression on to see if you can
make the DB fit onto a
single volume?  This may take longer but may allow you to get a current
backup until you have the
EOV problem fixed.
