Ray, I think that what you want to consider is that you will be allocating a
dataset (without secondary growth potential).  You then tell ADSM that it
has a volume within the storage pool.  When you need to add another "volume"
because you are filling up, you basically allocate another dataset and tell
ADSM that it now has another volume by extending the DB.
