ESX 6.0 suddently restarted

if you have installed OMSA

Dell OpenManage Server Administrator (OMSA)

then check the hardware logs.

all the best

Dear Andrew

thanks for quick list to check. This computer is running in data center with all expected redundancy, power including. Firmware and ESXi build are still the same, i.e. they are old maybe, but considering that I did NO change over last 2 years in any configuration of hardware of virtual machines, I believe this should not be issue.

For Hardware - what I can see in vSphere client, all is OK.

I suspected that there could be some problem with failed drive, so I downloaded full logs from Perc raid card, but those looks quite good as well.

For logs - please advice what I should check?

PSOD? - what is it, please?

Thanks

Vladimir

You’ll be surprised what firmware and build versions fix even after 2 years

Can you repeat the problem!?

Otherwise one off - or hardware issue!

You need the system event log as per above.

If it has only crashed once in two years that's pretty good, I tend to put such one-off events down to cosmic rays.

Yes First item in my post!

Logs will not show much!

Logs may show a power loss event for one PSU, although not both as no electricity to write to BMC/iDRAC.
