Sudden Reboot

[nibble]

Good day everyone,
weve got an HP-N4000 that reboots/shutdowns by himself. We traced the syslog, dmesg, etc... but could not find anything wrong. We suspected its hardware related but we dont have any proof. Please see attached tombstone files. Any help are highly appreciated.

Here's the cpumap file from /var/tombstone

looks like a hardware panic, log a call with HP

It seems that processor 6 is gone bad. This processor has caused the HPMC. As you can see in the CPU infolog, there is no entry for Processor 6 . Only 7 processors are listed in both infolog and tombstone files at the end.

The server had 8 processors online right?

The server had 8 processors online before this HPMC.

hi,

if you had 8 procesoors and lost no 6, then its likely you have a B revision N4000? is this right?

A3639B

if so have you got a processor trim card installed?

You may need one as there was a bug in the B rev boards that need it with 8 processors in certain situations.

you can check by looking at the fru information in system menu of STM

should have part number A3639-60026 0r 60027 for the trim card and system board part number A3639-60020

or open the box and look at the back left corner for a board sticking up.

Nibble,

You can also look at the /var/tombstones file for a ts99 file which would point to a H/W problem. The only thing is I think that HP would have to review the out put.
