Then I replaced a good one to CPU3 and still see CPU3 deconfigured. I want to know if that indicates the problem is on system board, or psm.
Thanks.
Solved! Go to Solution.

SolutionYou have to manually enable them again in BDC.
Go to COnfiguration menu and there is command to re-configure the processor. You have to do hard restart (power cycle) to recognize the new processor.
First you have identify the correct processor, Based on the logs.
Hope you are replacing same model/speed!
Do you have 2 PSM and 4 Processor?

Re: CPU Replace & Re-configure
How can we find out what cause the CPU deconfigured, even though we can manually re-start it?

Re: CPU Replace & Re-configure
See your /var/adm/syslog/syslog.log
(Hope you have not disabled EMS!)
Post the syslog if you are not able to find out which processor.

Re: CPU Replace & Re-configure
syslog.log has no lpmc error. It only shows 2 CPUs of path 160 & 162 are configured. From BDC, I see CPU3 is stopped and deconfigurared. Though manual re-start could bring back the CPU, my fear is:
1) would this CPU go bad again?
2) would psm go bad in this case?
3) would system board go back in this case?
Any comments?
Very appreciated.

Re: CPU Replace & Re-configure
Without any reason a CPU may not get de-configured.
What GSP log says?
Press Ctrl+B in console and from GSP>sl and press e for error logs.
Generally a CPU get de-configued during restart! did you restart?
run
/etc/opt/resmon/lbin/moncheck
to find out whether your processor is monitored for LPMC. You should see some thing similar below.
/system/events/cpu/lpmc ... OK.
For /system/events/cpu/lpmc/cache_errors:
Events >= 1 (INFORMATION) Goto TEXTLOG; file=/var/opt/resmon/log/event.log
Events >= 3 (MAJOR WARNING) Goto SYSLOG
Events >= 3 (MAJOR WARNING) Goto EMAIL; addr=root
Events >= 4 (SERIOUS) Goto TCP; host=hostname port=49296
Also check /var/tombstones/ts99 ts98 ts97 ..etc for possible catch.

Re: CPU Replace & Re-configure
The problem is bad enough that the CPU has deconfigured itself. You want to get this CPU replaced, NOW. It isn't doing anything for you as long as it is having problems.
Good Luck - Tim

Re: CPU Replace & Re-configure
Your CPU is anyway bad. Replace it ASAP.
Remember re-configure the processor in BDC after replacing with new CPU.
