This may be my favorite post yet. There will come a time when you need to shutdown your cvm. I always recommend checking your cluster resiliency status and putting the cvm in maintenance mode before you do this.
Connect to your cvm via ssh, and execute the below command.
nutanix@cvm:~$ cvm_shutdown -P now
If your using ESX or AHV, don't forget to put those nodes in maintenance mode before shutting down the node.
To gracefully shutdown you AHV node:
root@ahv# shutdown -h now
