Deconfigured Cpu'S

mjos — Tue, 27 Jan 2009 09:02:37 GMT

On my rx8640 server, when I do a parstatus it shows that two CPU's are deconfigured.
How do I configure them.

[CPU Details]

Type : N/A
Speed : 1418 MHz
CPU Status
=== ======
0 OK
1 OK
2 Deconfigured
3 Deconfigured
4 OK
5 OK

7 OK

CPUs
===========
OK : 6
Deconf : 2
Max : 8

Any info will he highly helpfull - thanks

The reasons for a deconfigured CPU could be various like i/d cache h/w failures and/or exceeding the LPMC thresholds of i/d cache errors, bus problem etc. These problems would make the CPU as "not responding", the firmware will detect the "degradation" and it will de-configure it. This all happens during CPU self test routines on power-on as well while system is up and running OS.

is there HP Integrity Management Agent installed there?

how many cells in there?

these 2 processors are in same cell?

There are 2 active cells

There are 14 processors which makes it dual boot

How do i check whether these two processors are part of same cell?

Yes both the deconfigured CPU's are part of the same cell - cell 1

all right then. check the firmware of that cell board. may be some mismatch there.

BTW, if your OS claimed all the CPU's, check with the 'top' command.

TOP is showing 14 CPUs

Since two CPUs in Cell 0 is showing as deconfigured, TOP is shoiwng as 14 CPUs

How do I check the firmware of the cell board. Is there any way...I can check or modify the status or the CPU from the EFI shell

Re: Deconfigured Cpu'S

sujit kumar singh — Tue, 27 Jan 2009 12:50:15 GMT

Hi

1)the Firmware for all the parts of the SD can be checked logging onto the MP Console.

GO To the COmmand Menu.

MP>CM
from there give command sysrev.

MP:CM>sysrev

this shall showe all trhe firmwares of the SD that is PDC,PDHC,CELL,IO etc.

2)the other part is that the Deconfigured CPUs can be made to use on the next boot only.

3) as this is an SD, Firmware (upgrade if reqd) and the CPU operations better to get done by logging a Case with HP and Authorosed HP Engineers only.

Sujit

Check on the FPL logs on the mp, and search for this type of message:

CELL_HW_DEGRADED

if you see these type messages, you have a HDW issue on the cpus

Re: Deconfigured Cpu'S

likid0 — Tue, 27 Jan 2009 13:21:11 GMT

Sorry i didn't see your other post, you can try and enable the cpus from the efi:

cpuconfig

to see if the CPUs are shown as de-configured.

If this is what has been done, then:

cpuconfig 0 on
cpuconfig 1 on
cpuconfig 2 on

Re: Deconfigured Cpu'S

sujit kumar singh — Tue, 27 Jan 2009 14:42:45 GMT

hi

just in add of what orange_adm says the
#cpuconfig on

considering this an SD

might take the form as

EFI Shell>cpuconfig on

to activate the Deconfigured processors.

where CELL_NO can take the form of 0/1 , 1

etc that means 0/1 is in the Cell local format and reads Cabinet0/Cell1 and later reads local format that is Simply cell 1.

Obviously for a multicabinet SD.

In addition to being deconfigured as part of predictive, and being explcitily deconfigured via cpuconfig, isn't it possible that the cpus are iCOD? I don't know what that would look like at the various levels but thought I would mention it.

Re: Deconfigured Cpu'S

mjos — Wed, 28 Jan 2009 05:40:04 GMT

Thanks, I was able to make the CPU's up through the EFI menu.
However is there any way to check whether these CPU's are part of iCod

Re: Deconfigured Cpu'S

sujit kumar singh — Wed, 28 Jan 2009 06:30:42 GMT

Hi,

to check if the CPUs on the system are a part of ICOD or ICAP, the following commands can be tried.
#icapstatus
#icod_stat

#icapstatus

Hi

can you also immediately post the icod_stat -v

Hi

and
also

#icod_stat -u

these shall be the ICOD logs.

Hi,

There is no icod_stat -u or icod_stat -v
