1.  You need to cap the LPAR at the 200 MIP level.  (on the panel I
believe it's a check box under "Initial Capping")  If you have 2 LPARs
on a 1000 MIP machine, for example, and all CPs are shared, you could
weight the capped LPAR at 20 and the other at 80.   (20/100=.2,
.2*1000=200)

Relative weight LPAR sizing is subject to the mix of LPARs that are
active at any given point in time.  In your example, if the LPAR whose
weight is 80 is not IPL'd then the LPAR with weight=20 will get 100% of
the processor (1000 MIPS in your numerical example) without changing the
weight numbers.  This is a far cry from the 200 MIP target.  I believe
that the calculation is:
  
  ((LPAR weight)/SUM(all _active_ LPAR weights))*(CEC capacity)

Again, assuming that initial capping is activated.
