Are these LPARs in the same Sysplex? Two beneficial effects if they are:

1) You could - with IRD Weight Management - have weights shifted between
the LPARs.

2) Sysplex PI for important works comes into play.

is defined as having 50% of the capacity of the entire machine, uncapped
across the board.  In this scenario, if both LPAR1 and LPAR2 are running
flat out, each LPAR will take 50% of the machine.  If one of the LPARs is
busy and the other isn't doing anything, the busy LPAR will "steal" cycles
from the not busy one.  That's the easy part.  Here's where my thoughts get
fuzzy.  Is there a way to differentiate between high priority work on one
LPAR and low priority work on the other LPAR.  Here's what I'd like to do:
Say I'm running a bunch of production on one LPAR and a bunch of test work
on the other one.  I'd like to be able to steal cycles from the test LPAR
and give them to the production one.  I know WLM handles this within an
LPAR, making sure the high priority work gets the cycles it needs, but is
there a mechanism where I can do this across multiple LPARs?  If there is,
can somebody point me to the right place for learning how to configure this
to happen automatically?

that regardless of which LPAR the high priority work is on, it gets the CPU
