  • 1.  How to disable auto-restart after PSOD

    Posted Jul 28, 2021 12:30 AM

    Hello everyone,

    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

    James

    HI,

    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.

    Cheers,

    Hey,

    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.

    /var/run/log/hostd.log

    /var/log/vmksummary.log

    /var/run/log/shell.log

     

    Cheers,
