P550 showing 1 processor 2

This is a new machine. No open HMC ports so we have to order another. No logical partitions either, like I said it is a new machine. If someone has access to a multi processor P550 I would like to know how many procs it shows when you run lscfg. The P520s we have that are two-ways show two processors.
Thanks,

Sounds to me like you don’t have an HMC, is that correct?
Sorry it is so hard to read but you try getting this lot across:
On a p5 machine, you don’t have the “partition stand-by” option any more.
On power 4 you turned the power on and it would go to the OK prompt. i.e. the service processor was initialised, then you could boot SMP (the whole system up), no LPAR or HMC stuff involved.
Or you could use the HMC to boot to “partition stand-by”
Then you could do LPAR stuff, activate any CuoD features and boot LPAR’s.
On p5 there is no OK equivalent, turning on the power takes it to what used to be called “partition stand-by”, where, on a Non-HMC machine, you can boot to what used to be called a full system partition, which is an encoded partition that includes all resources (without any CuoD resources because you need an HMC to activate them).
Or if you have an HMC you can boot the default full system partition (with or without activating CuoD resources) or you can create LPAR’s (with or without activating CuoD resources) and boot them.
Seems odd that you might have a CUoD p5 without an HMC because you need the HMC to accept the CUoD licence to activate the CUoD resources.(but I have heard this is / was possible)
I think lscfg will display ALL of the enabled CUoD sysplanar resources in the system on ANY LPAR but for the CuoD stuff to display it needs to be enabled / registered via the HMC CUoD registration – for which you need an HMC.
So if only 1 CPU is registered and the other 3 are CuoD you will need an HMC to be able to use the 30 day trial or to register them before lscfg will display them.
When I get the chance I will check out the lscfg on a 4 CPU p550 (no CUoD) and let you know what I find.....

hfaix: see above, I think even on power 4 the lscfg displays all sysplanar (processor, memory, power and cooling) resources, they certainly cause errpt entries / errors on all LPARs even if the resource is only configured on one other LPAR.
Plamb: all p5 use the same method to communicate with the HMC, two ethernet ports connected to the FSP (FSP = Flexible Service Processor not “full system partition”, another nightmare IBM acronym problem...), hmc1 and hmc2. Yes, SSH is the only option, telnet is disabled on p5.

You are right I have no HMC for the power5 currently. We have 2 HMCs but we purchased them with our power4 hardware and IBM said that they will not work with a mix of power4 and power5. I don't know if this is because of the application level of the HMC or if it is just incorrect information. Our current HMCs use serial cables attachments to the power4 servers. But if what I'm hearing you say is that it can run off of ethernet then maybe I need to do some more research. If any one can qualify this information then great. And any resources you can point me to that would show me how to set this up using enthernet instead of this serial cable method then great. If you have not figured it out yet this whole HMC thing has got me stumped.

The 550 is a 4 way machine so you could have 1 - 4 CPUS
Where are you running the lscfg command if you have no LPARS yet?
"If you always do what you've always done, you will always be where you've always been."

rzs0502, see above. If you don't have an HMC the system will power on with the default profile of all resources.
There is a full system LPAR loaded in the manufacturing process. It is just like turning on an old pre-LPAR system.
When you apply power a p5 goes to LPAR standby rather than OK but there is a preloaded full system LPAR profile and when you hit the white button it boots a manufacturing loaded "full system partition" - you don't need an HMC if you don't want to use LPARs - it is just like hitting the button on a pre / non-LPAR system, it goes from stand-by / OK / partition stand-by to a full system boot (the first "stand-by" in the last sentence was there for the people who remember the old MCA SMP / early multiple bus boxes that went to stand-by rather than OK).
tcorum, I would be surprised if IBM would let you order a CUoD machine without an HMC but I believe it can be done if you specify that you already have an HMC, which you do but yours are P4 not P5.
I can’t comment on whether you can control a p4 and a p5 machine from the same HMC but, like checking out my 550 processor resources, I will try to lok into it.

Is it fair to assume the full system parition is AIX 5.3? If so, have you applied the IBM AIX 5.3 Mandatory Fixes? How about ML 1? Did I miss where you say what level of microcode you are at? They've had a town of microcode problems with p5.
I don't think I bothered with the full system partition on my 520's. I have everything booting from san, so I didn't bother with the local disk.
