Larry,
On my production lpar, here's my new profile settings.
I will be changing from capped to uncapped, and now using Shared processor pool 1.
I'm not sure on the rules for the virtual processors.
Should virtual equal processing unit?
They always seem to round up to the next higher integer.
I'm not totally understanding the help text, see below.
In their example, I don't see how they get 10.
When I try putting in a higher number, states invalid.
Also, what is a good recommendation for weight?
Desired virtual processors
The desired number of virtual processors for the logical partition that is associated with this partition profile. The desired number of virtual processors is the number of virtual processors that you want to assign to this logical partition when you activate this partition profile.
When you activate this partition profile, the managed system calculates the ratio between the number of processing units committed to the logical partition and the desired number of virtual processors. If the calculated ratio is equal to or greater than the minimum processing units required for each virtual processor, then the logical partition is assigned the desired number of virtual processors. Otherwise, the number of virtual processors is the number of processing units divided by the minimum processing units required for each virtual processor, rounded down to the previous whole number. For example, a logical partition has 1.00 processing units committed to it, and the minimum processing units required for each virtual processor is 0.1. If the desired number of virtual processors is less than 10, then the managed system uses the desired number of virtual processors for this logical partition. Otherwise, the number of virtual processors for this logical partition is 10 (1.00 processing units divided by a minimum of 0.1 processing units for each virtual processor).
Any change you make on this page takes effect only after you shut down the logical partition and reactivate this partition profile.
Minimum shared processing units: 1.5
Desire shared processing units: 1.5
Maximum shared processing units: 3.0
Shared processor pool: SharedPool01(1)
Virtual processors.
Minimum processing unites required for each virtual processor: 0.01
Minimum virtual processors: 2.0
Desired virtual processors: 2.0
Maximum virtual processors: 3.0
Sharing mode
X Uncapped Weight: 128

YES you CAN set all partitions for a high of 3. The IBM i LPARS should all be set to draw out of a shared processor pool with a 3 core limit.
That will keep you clean.
Nothing else should draw from this pool. Do not use the defaultpool.

I have 8 active cores.
3 cores licensed for i5/OS.
Can I set the high max to 3 for all LPARs.
I thought I remember an error occurring if the total max exceeded the total licensed?
This was back in 2012, so I don't have the details.
