Vmware ESXi Server reboot

I have a server (HP ProLiant DL380 Gen9, Intel Xeion CPU E5-2609v3 with 2.04 TB) running VMWare ESXi 5.5.0 with 2 VMs. I've been having issue of sudden reboot every once in a while. I've gone through VMware Knowledge Base (Determining why an ESXi/ESX host was powered off or restarted (1019238)) but nothing comes up.

I guess my question is - can I get some sort of hint in the vmksummary or vmkernel log files to find the issues ? I've gone through those files but nothing pops-out of the ordinary before the reboot happens.

What are the places to look in the log files ?

You are 3 years behind on patches with that build. Update to the latest available build first before continuing troubleshooting efforts.

can you attach the hostd and vmksummary logs?

I do need to update to latest build version. Meanwhile I'm just poking around to see if I can find something.

I've attached hostd.log and vmksummary.log.

Thanks

Login to the host's iLO interface, and check the logs there, to find out whether they contain entries related to the reboots.

2018-01-29T16:34:37Z bootstop: Host has booted

from the vmksummary, it shows that the host is booted and coredumped as per the logs.. This indicates a hardware specific nature of issue or an ASR

If it is user initiated then it should list host is booting first and then host has booted

Thanks a lot...and I guess to find out the exact hardware issue - go through the IML logs ?

Try this command on ESXi host esxcli hardware ipmi sel list and share the output.. if its blank or no valid output, needs to check the ilo logs

That is not valid, you need to look into the SEL logs from the ilo or any hardware events on the ilo

I would like to check where you have taken the ssh session? That command would not work on ESXi host.. It is for hp hardware

Hi,

Do you see the problem even when you have both PSUs connected?

I had a similar problem (faulty hardware) and issue was resolved when both the PSUs were connected.

Thanks
