I think you've hit the nail on the head Richard. KEEPMP is set to NO, and we set MountRet to 2 mins - with only 4 drives we need those vols out as quick as possible.
My solution is to set the storage pool to have only one scratch volume - in the last 2 years of backing up these SQL machines we haven't got more than 18% of a volume, so I think we'll be OK with that one vol for a bit. Much appreciated.

Your KEEPMP and MOUNTRetention values may cause TSM to dismount the recently written volume. But if a volume is dismounting, TSM will shrug its shoulders and call for a scratch to be mounted - ostensibly because it's faster than waiting for a full dismount-store-retrieve-remount tape sequence.
