Removing a vCenter HA Configuration

To my knowledge there are only two ways to deconfigure/remove a vCenter HA Deployment.  The first method is the easiest and involves using the vCenter UI to "Remove vCenter HA".  The second method is to use the shell on the active vCenter node and run the destroy vCenter HA command. 

Method 1:

  1. Login to vCenter.
  2. Click on your top level vCenter menu item.

  3. Click on Configure.

  7. Click Delete Passive and Witness node then press OK.

It's normal if it takes a few seconds to load after clicking the checkbox for deleting the nodes.

Method 2:

  1. Power down the Passive and Witness nodes and delete them.
  2. Access the shell console on the active vCenter node.  This can be done via SSH or viewing the VM Console.
  3. Once you're in, type shell to access the bash shell.
  4. Run this command to remove the vCenter HA configuration vcha-destroy -f.
  5. Reboot the active node, when it comes back up it should be a standalone vCenter instance.
