I am new to ESXi and vCenter. We have installed both of them on RAID 1, Dell branded SSD on PowerEdge Server
My ESXi v7 and vCenter seems to be experiencing a shutdown/reboot once every 2-3 days.
I would like to disable the auto-restart to expose the error message if this happened, how would I do it?
And, is there a way to know why it restart? I am not sure what logs and where I should look for?
Thank you very much
The delay or timeout can be extended in the advanced system configuration options of the esxi hosts.
Host » Configure » System » Advanced System Settings
You should look for Misc.BlueScreenTimeout. It's value 0 by default which means no timeout. I think the maximum value is (or was) 65535 seconds which is around 18 hours.
Regarding the value of blue screen timeout: If the value is different than 0, then ESXi reboots automatically after the purple screen.
I also recommend to check the /var/log/vobd.log file on the esxi host. This one is very easy to understand.
If there is nothing in it you can check the followings as well.
