Interview Question : (Moderator Please move it to right group if this is not)

I encountered below question.

ESXi Host is Down ? What troubleshooting steps you will take ? Tell what all will you check ?

Guys what will be your answer ......

Some thoughts:

• Check whether the host is powered off or still powered on?
• If powered off, check the power and/or hardware (e.g. iLO logs or other harware management tools)
• If it is still powered on, does the console show a PSOD or the DCUI?
• If it's a PSOD, check for hardware issues or driver issues with e.g. unsupported hardware.
• If the console shows the DCUI, check networking?

Depends what your view of down is. If down means that the host dropped out of vCenter, check whether:

• The host can still be pinged
• If a SSH session is still possible, if so, restart the management agents. services.sh restart might help here.
• The logs tell any relevant information

If the host is completely offline, I can only confirm Andre's points, but I would add:

• Check the logs (vmkernel.log, hostd.log, etc).

It's a very wide-open question so there isn't really one answer. I guess it kinda depends but for every case you encounter, the relevant log files always tell you more.
