ESXi Logs

Posted on 2011-04-21

I am new to ESXi.

I installed using the vendor specific version for my hardware.

The only additional software I have installed is powerpath.

Well one of my Servers has just rebooted for no apparent reason.  I checked the console looking for a pink screen but all I saw was the server booting back up.

How can I investigate why the server rebooted.

I pressed F2 and tried to look at the logs on the console, but with out the service console I couldn't really work effectively.

    What is the server? Is the server on the hardware compatibility list

    If the server is very new, I would maybe run a memory test using Memtest86 available from here to check the memory

    if the problem continues, you probably need to collect more information.

    if it's ESXi, looking at the logs will be fruitless if it wasn't a clean shutdown.  You should set up a syslog server to send the logs to.  VMware has a virtual appliance (vma) you can use to be a syslog server, but it it's on the host that crashes they you might not get enough data to find out what the cause was.

    ESXi is basically memory resident, I would advise to setup up a vMA and use it for syslog
