ONLY DO A SINGLE LOG & A SINGLE DB !!!!!!!!!!!!!
I ran into the same thing... I exceeded the max continuation of a EXEC card
!
Just to the single log & single db vol....
then do formats of the other db vols like normal and go into the running tsm
that you started with the single log & single db vol and add in the
additional db vols

hope this helps
later, 
Dwight
