Hi,
IBM documentation says the CPU Compatibility Mopde can be changed from th HMC in LPAR properties, but i have no option to change it there, it is only displayed. Anyone?
Regards, firefox111
What p/POWER technology are you using?
Maybe this chapter helps:
Processor compatibility modes
See the different matrixes in the links below.
Is the HMC and VIO version up-to-date?
I know this site, but it does not say how to change the mode.
I'm using Power7 (8233-E8B) and the LPAR is in P6 Compatibility Mode. I need to switch it to P7 Compatibility Mode.

I also have a test environment with HMC 7.5.0 and p710/p720 with AL740_088.
i do not have an hmc for a screen shot. it may be all you need to do is shutdown, not reboot -and restart.
did the partition arrive via live partition mobility from a power6? if so, the shutdown/activate will automatically change to power7 mode.
to change it manually, effective at next activation - not reboot - iirc it is changed via the partition properties dialog. can also be done at command line, but i do not the command. that will be something like "chsyscfg -m ... -r lpar ...."
hope this helps!
Might sound stupid, but have you been in the correct place ie. in the profiles definition?
From some documentation:
There is some steps in it, that might help to identify the problem:
Verifying the processor compatibility mode of the mobile partition
Have no HMC at hand like Michael, sorry.
OK, I got it.
For some reason the profile I checked before does not have the processors tab. I created another one now and it works. Thanks for your help.
another happy customer
