Error at syslog

[Utpal Krishna]

Hi,

I am facing the following error from one of our HP-9000 server:

mis vmunix: LPMC type : D-Cache Parity Error

Here MIS is the hostname of our server.


Can anyone tell me the probable reason for this.


Thanks

LPMC
Low priority machine checks
These messages come from the processor on the server.
As stated above these messages are low priority.

Make sure these messages do not come frequently,as then you should plan to replace the processor throwing these messages.

This is the Data Cache parity error in one of the processor. If you have contract with HP, pls talk to them with details.

For getting further details you may send the /var/tombstones/ts99 files to them.

You can also see the file
#strings /var/tombstones/ts99

these are processor logs

HPMC
But do check whether there are HPMC errors for the processor/cache.

If then,replace the processor.

[Steven E. Protter]

If this system does any kind of work you depend on, get the CPU replaced now.

You can test it by running xstm in X and excersizing the CPU.

Hi

Thanks everyone for the information.
But I am adding that after this(after 16 Hours) I cannot ping to my server and also cannot login to server also the attension light is blinking. Can anyone tell me the probable solution for this.

Thanks

I couldn't get you!

[Jeroen Peereboom]

Utpal,

apparently your server crashed.
Did you try to login at the console?
If the server is 'dead', try connecting to the GSP by entering '^B' at the console.
The attention light indicates there are messages in the logfile of the GSP.
You may view the logfile, and you may reset the hardware (= hard reboot of your server).

goto GSP .

^b at console. u shall get GSP prompt.
type "sl"
then "e". This will give the LPMC / HPMC error details. In the last of each event there will be a number of hex codes. U can communicate the same to HP solution center people. They shall tell you which part is defective. Can u forward me the hex codes

Once you see these messages at GSP prompt, attention light will go to off state

a LPMC is usually a memory related error. Usually one of the following has failed or failed out at the time of the crash:

Memory Card/Carrarier or Memory Port on the system board. If there was a system board related you would have received a LPMC with a HPMC then you would cored and panic'd. All of this would also be present in your Guardian Processor.

I would run a Q4 and place a call to the down server team at HP and get a tech onsite with some memory and board. I have seen these alot.

Not for Nothin a LPMC is usually recoverable, normally it's caused by a rouge C program trying to lock a memory region that is unlockable or unavailable and that cause's a memory fault and some times throws an LPMC.
