I have one disk pool and one tape pool. Unless you have different
types of disk, I don't see any point in having more than one
disk pool in your heirarchy.

We have not been using ADSM all that long. I would think that
you would keep the tapes for as long as you need the files on
them. Remember, that files get expired per the specificiations
of the management class.

I force migration every weekend by lowering the high migration
threshold to 30%. As we backup more data I will probably migrate
more frequently and make the high migration threshold even lower.
