Before putting the Gen8 servers into production (as with all servers), I ran the comprehensive HP diagnostic tests on them for 24 hours. I also ran the intensive MemTest86 tests on them for 24 hours as well. All tests passed. I feel safe assuming the hardware is okay. The little information I have found on the matter suggests it is a Kernel watchdog issue, but those articles offered no help in resolving the problem. I am not suggesting it is an oVirt issue. I am simply hoping that someone in the oVirt community has encountered the same problem and can offer a solution or work-around.

I'm not sure if fencing is not generating those NMI options. Have you tested the fencing ? If not, follow the documentation to test fencing and if that's the reason for the NMI.Also check any pending firmware updates like the newest iLO4.

Hi Diggy, I'm not sure if it's an oVirt issue, but it can be a network or firewall issue. Did you test the connection between oVirt hosts and the iLO interfaces? Simple tests like ping to ensure one host can reach others iLO interfaces and ipmitool to ensure you can connect to the management interfaces?

I have oVirt Node v4.4.8.3 running on several HP ProLiant Gen8 servers. I receive the following error under certain circumstances: "An Unrecoverable System Error (NMI) has occurred (iLO application watchdog timeout NMI, Service Information: 0x0000002B, 0x00000000)" When a host starts taking a load (but nowhere near a threshold), I encounter the above iLO-logged error and the host locks-up. I have had to grossly under-utilize my hosts to avoid this problem. I'm hoping for a better fix or work-around. I've had the same problem beginning with my oVirt 4.3.x hosts, so it isn't oVirt version specific. The little information I could find on the error wasn't helpful. Red Hat acknowledges the issue, but limited to shutdown/reboot operations; not during "normal" operations. Anyone else experienced this problem? How did you fix it or work around it? I'd like to better utilize my servers if possible. In advance, thank you to anyone and everyone who offers help. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://urldefense.com/v3/__https://www.ovirt.org/privacy-policy.html__;!... oVirt Code of Conduct: https://urldefense.com/v3/__https://www.ovirt.org/community/about/communi...
