Re: Creating an LPAR - the continuing saga......

[Pete Helgren <pete@xxxxxxxxxx>]

OY!   So, this is where my head explodes because I have never really 
totally understood the whole "Processing Units" vs "Virtual Processors" 
settings when using shared processors....

So, I have the whole processor to dice up while I wait for the IBM 
configuration juggernaut to activate my other processors.  In the IBM i 
profile, I'd like to start with giving 1/2 of the system processor to 
the Linux LPAR.  So, logic tells me that under the "Processing Units" 
settings I could set it something like:  .25 minimum shared, .50 Desired 
shared and 1.0 maximum. (the defaults were .05 for all)

So next there are "Virtual Processor" settings which have a value of 1.0 
for each minimum, desired and maximum.

Sharing mode "Uncapped"?  Weight?

Will that work?  Is it a sane set of settings....?
