Hi all,

We have a HP BL460c G8 that 6 days ago did an unexpectedly reset.

The system runs SLES 11 with sp2. I checked all the logs (/var/log/messages, crash, etc.) and i did not find something usefull to understand the reason of the fail.

The only errors that i found was the above in OnBoard Administrator --> IML Log

System error ---> An Unrecoverable System Error (NMI) has occurred (System error code 0x0000002B, 0x00000000)

ASR ---> ASR Detected by System ROM

Any help will be welcome.

The chipset detected an unrecoverable error condition and caused an "Automatic Server Recovery" (basically a hard reset) by triggering a Non-Maskable Interrupt (NMI). There's an excellent chance there's something physically wrong with the server, and you should probably run a diagnostic check as soon as possible.

If the OS locks up hard, watchdog timers (if configured) would eventually trigger an NMI. Non-correctable RAM errors, severe bus errors and over-/undervoltage are among the hardware errors that could trigger an NMI.

Do you have all the HP management agents installed and running? If not, some conditions that would normally result in a graceful shutdown (typically overheating) could progress to the point where a forced reboot would be considered necessary.

Edit: Have you seen this thread? It seems a buggy iLO driver can cause NMI ASRs under some conditions.

Hi Olmy and thanks for your quick response.

First of all I have checked the thread at HP forum. That's why I wrote that our systems runs SLES 11 with sp2. So I beleive that works now and it is not a problem.

I ran HP diagnostic tools and all seem normal. Since then I monitor the hardware from Onboard Administrator and there is no something strange.

Just because you're running SLES 11 SP2 doesn't mean all HP-specific drivers are updated. Have you installed a recent ProLiant Support Pack (PSP)?

Does HP System Management Homepage show any errors or warnings?

The two servers have the 2013.09.0(C) which is not the latest. The latest version is 2014.02.0(B). The reason that I have not installed the new version is that when I installed in one of them the system them did not recognize the Emulex cards.

Furthermore the HP System Management Homepage do not show any errors or warnings.

I don't think the SPP (Support Pack for Proliants, Yup! They replaced the PSP with another acronym for G7s and above) supports Emulex cards, That's Emulex rather than the HP branded variety.

I believe you should be able to boot directly into hardware diagnostics via the Intelligent Provisioning Utility accessed via the iLO on a Gen 8 server (or would that be within the POST?) Have you tried that to check for hardware problems? It's sort of like built in "SmartStart" Diagnostics.


Play Bonny!

Thanks all for your support,

The problem was that there was an upgrade in iLo. For the HP was a known problem. I installed the patch one month ago and still now everything works properly.
