Identify IBM P55A and P55Q

Hi All,

Please help to identify the machine type of IBM server.
Using AIX 5 OS.

From prtconf command, the output is like:
System Model: IBM,9133-55A
Machine Serial Number: 107C43H
Processor Type: PowerPC_POWER5
Number Of Processors: 4
Processor Clock Speed: 1900 MHz
....
....

Processor Type: PowerPC_POWER5
==> Here it is p5

System Model: IBM,9133-55A
==> Here it is 55A, but I heard that P55Q also will have the same System model ID (IBM,9133-55A) if we do prtconf.

Any other way to identify the difference between them (by listing system configuration)?

Thanks for the help...

Nope.

@padow: it doesn't hurt too much to expound a little, does it? I do appreciate your expertise here and i am glad that you are willing to share it, but if you are really interested in helping others you have to present your help in a way that makes it useful to them. "Just saying no" might be a viable approach when it comes to drugs, but definitely not in advancing AIX knowledge. Thanks for your consideration.

Back to the problem:

You seem to confuse the model of a machine and the processor type. A "model" is a complete computer, not necessarily different in terms of processors from another model. Maybe the one is rack-mounted, the other one a deskside system, etc..

If you want to find out everything there is about the processor use the command "lsattr -El proc0". You can also try "lscfg -vp -l proc0". (On really old machines you might have to use "cpucard0" instead of "proc0" as device identifier.)

Maybe you could lay out your problem in greater detail so we might find a solution for you.

I hope this helps.

@bakunin - you are right, my apologies.

The difference between the 55A and 550Q (also identified as a 55A) is that the 55A is Dual core and the 550Q is Quad Core.

What I meant to say is that there is no easy way to tell the 55A froom thye 550Q. I've asked my VAR (Value Added Reseller) as well as IBM technical support in the past and have yet to find a way to tell these two models apart at the command line or even by physically looking at them.

Thank you bakunin and padow for your answer..

I already have the way to identify 55A and 55Q from some guides.
As said by padow, 55A is dual core and 55Q is quad core.
So, by using lscfg -vp, I checked all memories module location.
If the locations contain Px-C8-Cy and Px-C9-Cx means there are 2 processor cards.
Then using Number Of Processors: 4 (this should be the total CPU core) information, I calculate using this formula :
Number of processors / number of processor card
== 4 / 2 = 2. It means dual core=55A

Correct ? :slight_smile:
