Hi Jerry,

 I have been a bit late coming into this post. One thing I seen to remember,
that I have not yet seen a reply to, is that you could also balance your 'hot'
and 'cold' data across disks. I will have to go and check out the commands,
sequence and implications if you are interested.

Cheers.
