vmunix: LPMC type : I-Cache Parity Error.

[SCI Tech Support]

I got this error (vmunix: LPMC type : I-Cache Parity Error) on one of the rp7400 server. I got this kind of messgae 20 days back.
Is there anyway to find out which processor is generating this error. I had checked in stm through logtool and also there were no files generated on /var/tombstones.

TIA

Have a look at this recent posting. Looks like there is not too much to worry about unless it is a frequent occurance.

Hi,

try this if OnlineDiagnostic is installed and running:
1) start 'cstm'.
2) on "cstm>" Prompt, type 'ru l'
3) on "Logtool Utility>" Prompt, type 'sr'
4) select recent file...
5) now do the formatting on typing 'fl' on the "Logtool Utility>" prompt...look for the LPMC event...there should be something about the corresponding HPA (hard physical adress) of the CPU experiencing this LPMC...

Anyway, a single LPMC is no reason of concern!

regards.

No, Its doesnt give me any details regarding the physical address, the following is the output from STM.

Hi,

the output you stated above is the about from the "sr" (select raw) command at "Logtool Utility>" prompt.

Try to do afterwards at that prompt first "fr" (format raw) and then "fl" (formatted log). This will produce a more detailed output...

If you are getting this error frequently
(atleast once a day) then you have to
replace the corresponding processor.
Once in two weeks, you can ignore!!

Thanks Tobias,

I had collected the formatted information, but i am not sure, which part in the command shows the processor thats giving error. I am attaching the file. Could you please have a look?

Your help is highly appreciatable.

Uhhmmm - attachment?

sorry....here is the attachment.

Hi,

The HPA info in the attachment needs to be translated to a CPU #. To do that you'll need to run up the STM software & tie that HPA # to a CPU #

Run up xstm & pull down Device & choose Select & then Class. Highlight CPU & click OK. Then pull down Tools & select Information & then Run

This will give you a report with *all* the CPUs & then just match that HPA # to the appropriate CPU #.

Rgds,
Jeff
