I'm not sure I understand what you mean; if the default volume is a 3380 and
the allocation is satisfied on a 3390, a larger volume, how would the space
allocation be increased for the larger 3390.

If SMS is configured with a default volume specified as 3380 and the space
allocation is satisfied on a 3390, the amount allocated will be adjusted to
account for the larger cylinders on a 3390.
