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....?

Ohhhhhhhhhh the dreaded 'De-Configured' :-( Sorry to see that. So you're out of luck to use them. I NEVER recommend de-configuring processors for this very reason. The only thing you save is a tiny amount of cost for sharwarma for PowerVM. You can place an order and get at least a processor or 2 or 3 reactivated but that will take time.

So for now you need to share that lonely processor. So in the profile for IBM i you need to change processing to shared and perhaps desire 1/2 core and then for Linux do the same. LIkely won't be a big deal because the processor will be shared and there is a fair bit there and you're not likely to run heavy duty apps on either side.

Hmmm...maybe one more pointer.. I created the NWSD, created the NWSSTG, linked the storage to the NWSD, downloaded the Linux ISO, got it mounted and ready.  Went back to the HMC and took the option to activate the new Linux partition.  But! I get an error that there are no processors available.

If I look at the system Processor, Memory and I/O panel it shows: 0.0 Available, 1.0 assigned to partitions, Configurable 1.0, Installed 4.0, Deconfigured 3.0

Perhaps I 1) Misunderstood that the processors that were not assigned to IBM (3) *were* available to other partitions OR 2) Missed a step where those processor are made available in the base system.

Seems although I have 4 processors in the 9009-41A and only 1 assigned to an IBMi partition, the 3 other processors aren't available.  There is an option to create or change a processor "pool".  Do I need to do that or did I miss something (again)?

Building the Linux LPAR now to see what else I can break....

So I THINK a missed step is that OOTB as you say machines with one partition have a checkbox set to "Power OFF when last partition is shut down."

On your HMC go to "All Systems > Your machine > General Settings."

Under the 'General Properties' the very last item is that checkbox noted above. Remove that checkmark. (And be sure to SAVE!)

Now when you power down your IBM i partition it should not go away because the SERVER will remain running even though the partition is down. I think this is the cause of your puzzlement!!
