DASD pools normally show the same values for %Mig and %Util, but for tape, it
normally doesn't.  From what I understand, from my own systems, %Mig measures,
basically, the % of tapes in use, with any data on them.  %Util shows how much
of that space is actually used.

I have a storage pool, 3 tapes (it's archive data), shows 73.8%Util, 100%Mig.
All 3 tapes have data on them, but
one is only about 1/3 full.

I may be wrong, but my theory has held out for me thus far.

If you don't have the time to do it right the first time, where will you find
the time to do it again?
