2 Deploy a New Platform Services Controller
If a Platform Services Controller instance fails in an environment that contains multiple
Platform Services Controller instances, you must deploy a new Platform Services Controller instance
and join it to an active node in the same vCenter Single Sign-On domain, and site.
3 Repoint Back the vCenter Server Instances to the Restored Platform Services Controller
After you restore a failed Platform Services Controller in an environment that contains multiple
vCenter Server instances registered with different external Platform Services Controller instances,
you must repoint back the vCenter Server instances to the restored Platform Services Controller.
Repoint vCenter Server to Another External Platform Services Controller
Joining external Platform Services Controller instances in the same vCenter Single Sign-On domain,
ensures high availability of your system.
If an external Platform Services Controller stops responding or if you want to distribute the load of an
external Platform Services Controller, you can repoint the vCenter Server instances to another
Platform Services Controller in the same domain and site.
n
You can repoint the vCenter Server instance to an existing functional Platform Services Controller
instance with free load capacity in the same domain and site.
n
You can install or deploy a new Platform Services Controller instance in the same domain and site to
which to repoint the vCenter Server instance.
Prerequisites
n
If the old Platform Services Controller instance has stopped responding, remove the node and clean
up the stale vmdir data by running the cmsso-util unregister command. For information about
decommissioning a Platform Services Controller instance, see https://kb.vmware.com/kb/2106736.
n
Verify that the old and the new Platform Services Controller instances are in the same vCenter Single
Sign-On domain and site by running the vdcrepadmin -f showservers command. For information
about using the command, see https://kb.vmware.com/kb/2127057.
n
If you want to repoint a vCenter Server Appliance that is configured in a vCenter HA cluster, remove
the vCenter HA configuration. For information about removing a vCenter HA configuration, see
vSphere Availability.
Procedure
1 Log in to the vCenter Server instance.
n
For a vCenter Server Appliance, log in to the vCenter Server Appliance shell as root.
n
For a vCenter Server instance on Windows, log in as an administrator to the vCenter Server
virtual machine or physical server.
2 If the vCenter Server instance runs on Windows, in the Windows command prompt, navigate to
C:\Program Files\VMware\vCenter Server\bin.
