I have the same problem. But I had Reclamation Threshold 100%. So even thought 
the most tapes shows utilization 25 - 30 % the tapes are full. I think that is 
a reason.

Andreas - You may have a combination of problems...

If the tape drive is reporting EOV and you see that the volume is far from full,
I would look into the firmware level being used on your drives.  We've seen too
many LTO firmware problems recently, and this may be another.

Your Query Volume output shows "Scratch Volume?: No" which suggests that you may
not be supplying a scratch tape pool for that stgpool: see if the stgpool needs
more empty, candidate volumes assigned to it, or implement a scratch pool.
In concert, I would also check whether your collocation setting for that 
migration
stgpool is requiring a separate tape for further migration to occur.
