To patch a vCenter Server Appliance configured in a vCenter High Availability (HA) cluster, you must remove the vCenter Server High Availability configuration and delete the Passive and Witness nodes. After patching the vCenter Server Appliance, you must re-create your vCenter Server High Availability clusters.

This procedure describes how to remove the vCenter HA configuration.

Procedure

  1. In the vSphere Client, log in to the vCenter Server from which you want to remove the vCenter HA configuration.
  2. Click the Configure tab, and select vCenter HA.
  3. Select Remove vCenter HA .
    • The vCenter HA cluster's configuration is removed from the Active, Passive, and Witness nodes.
    • The Active node continues to run as a standalone vCenter Server Appliance.
  4. Wait until the Witness node joins the VCHA cluster and then patch the Passive node.
  5. Delete the Passive and Witness nodes.

What to do next

Patch the vCenter Server Appliance as described in either Patching vCenter Server Using the vCenter Server Management Interface or Patching the vCenter Server Appliance by Using the Appliance Shell.

After patching the vCenter Server Appliance, you can configure vCenter HA. For information about configuring vCenter HA, see vSphere Availability.
