Today while trying to take snapshot of one the VM, end up with following error,
“The operation is not allowed in current state”
Then I tried to vMotion the VM to any other host but no luck, same was true for any other task however I didn’t see any issue with other VMs on this host.
I also checked for any associated running task but couldn't find any.
I had seen such errors earlier and most of the time such error occur because either the ESXi host or a virtual machine is in an unexpected state and to work around this, we just need to restart the host management agents.
Note: Before restarting the host management agents, make sure no Virtual machine is configured to poweron/off with host otherwise it may reboot.
To restart the VMware host management agent, connect to host over ssh using putty and run following commands,
/etc/init.d/hostd restart
/etc/init.d/vpxa restart

That’s it… J
