It's probably worth ruling out the obvious stuff first.

If the end-of-volume is reached then a new scratch tape will be required. If 
for some reason a new scratch tape cannot be mounted (eg there are no scratch 
left) to complete the writing of the spanned file/object then the store 
operation will fail and the previous end-of-data point on the tape will be used 
as the starting point the next time the tape is mounted. I've seen many 
occasions where a  paucity of scratch tapes has resulted in the end-of-tape 
being reached repeatedly on the handful of remaining 'filling' volumes.

In the cases where the end-of-volume has been reached, has a scratch volume 
been successfully mounted subsequently to complete the operation?

Regards
Neil
