Re: Increasing MAX CPU of LPAR - HMC managed

Hi Paul

You can set the max to 3 for all but probably better to set it to a
"practical" or likely limit. If all the LPARs could reasonably expect a
requirement for 3 procs "on demand" then this might be a reasonable idea.
I would certainly do that for Prod but on Dev systems I might waver and
make it slightly harder for the dev guys to obtain extra processor when
they felt they needed it (just to give me extra bargaining power, not for
any technical reason).

The license total is compared to actual processor assigned and in use but
this can be affected by any LPARs that are uncapped (if you are using
uncapped) particulalry if you are not using a shared processor pool.

If you don't have one you should create a shared processor pool for 3 cores
for your i licenses and have all your i5 LPARs drawing processor from that
shared pool. That will make your life a lot simpler.

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.

Hi Paul,

HMC profile setting is loaded when LPAR is powered on.
So a normal "re-IPL" does not work. You must shutdown and start again.

Consider setting high MAX values and reasonable DESIRED values so you'll
be flexible.

I'd like to DLPAR and increase the LPAR CPU.
Currently set at 1.5
Max is also set at 1.5.

I changed the profile's Maximum shared processing units from 1.5 to 2.0.

It will not allow me to DLPAR and increase beyond the 1.5.
The value is beyond the maximum value.

Is an IPL required to increase the max?
Processing mode - shared
