HA is not working properly

Hi,
I have 4 hosts connected to vcenter with HA enabled on the cluster.
I had some issues with one of the hosts and I was forced to reset it without entering the host into maintenance mode.
To my surprise, none of the VM's which were allocated on the host migrated to the other hosts, instead they were powered off and I had to power them on only when the host was back online.

What can be the problem here?

What is the version of your VCenter?

Have you checked any error Events generated?

Refer below articles for error messages if any generated

I haven't seen any errors during the downtime.

Shutting down the host is NOT hardware failure and will not cause HA to kick in.  Did you shut down via vmware at all or do a manual power cycle?

manual power cycle.
So on what conditions HA will kick in?

VMware HA works or kicks in on a host failure.

Eg pull the power out of the host not a controlled restart or power off reboot or shutdown

What you did was not host failure

What you did is a very common mistake and you will only do it once.
