Vmware Fail over question
We are running 4 ESX hosts on our Farm and configured 200+ servers. All ESX hosts are clustered, last night few linux boxes moved to other ESX hosts on the farm and rebooted automatically. My question is that, when VM boxes move to other ESX hosts, it shouldn't reboot right? Why it got rebooted? Please advise.

I'm new to this. How do I check whether EVC mode enabled or not? Also, I forget to provide some other info. All the VM boxes which were running on this specific ESX host got rebooted. Also, this specific ESX host failed.

yes, EVC is enabled, but if ESX host failed VM boxes shouldn't reboot right?
As per hanccocka's previous answer - the server's will reboot
If the host failed, then the VMs would start-up in HA mode, so there would be a VM restart.

Thanks a lot. Sorry for asking stupid question. How do I know it failed by Vmotion event or DRS event?
What failed? the ESX host or the VM.
VMs did not fail, they restarted due to ESX Host failure.
If you need advice on ESX host failure, that's off topic, and requires another question, to examine the various possibilities of why the ESX host failed.

ESX host was failed, because of that VM failed over to another ESX host, once it's moved or it got rebooted automatically. Is this Vmotion event or DRS event? Is this clear?

Here is the line from your link.
• Automatic detection of server failures. Automate the monitoring
of physical server availability. HA detects server failures and
initiates the virtual machine restart without any human intervention.
Does it mean virtual machine should resatart? I'm really confused with the DOC.

Thanks a lot for all of your explanation. I'm just clarifying your third line:
When you say restart the VMS on other ESX host, it means VM gets reboot on other ESX host? I'm confused with reboot and restart term, please correct me.
3. The HA function restarted the VMs on other ESX hosts.

It's NORMAL. This is what HA does.
