Create an additional vCenter Single Sign-On node as a partner to an existing vCenter Single Sign-On installation in the same location so that you can configure a third-party load balancer to provide vCenter Single Sign-On high availability.



  1. In the software installer directory, double-click the autorun.exe file to start the installer.
  2. Under Custom Install, select vCenter Single Sign-On, and click Install.
  3. Follow the prompts in the installation wizard to review the Welcome page and accept the end user patent and license agreements.
  4. If the prerequisites check screen shows any problems, cancel the installation, correct the problems, and restart the installer.
  5. Select the deployment mode High Availability.
  6. Enter the information to point this additional node to the first vCenter Single Sign-On server.
    Note: If the primary node is in a high-availability cluster, enter the address of the primary node load balancer.
    1. Enter the partner host name.
      The partner host name is the IP address or DNS name of the existing vCenter Single Sign-On server to replicate from.
    2. Enter the password for the vCenter Single Sign-On administrator account of the existing vCenter Single Sign-On server (administrator@vsphere.local).
  7. Review and accept the partner certificate.
  8. From the Site name drop-down menu, select the site name of the first vCenter Single Sign-On server, and click Next.
  9. Accept or change the HTTPS port for vCenter Single Sign-On.
  10. Accept or change the default vCenter Single Sign-On installation folder.
  11. Review the installation options and click Install.

What to do next

You must place the primary and high-availability vCenter Single Sign-On instances behind a third-party load balancer.
Important: If you do not complete the vCenter Single Sign-On high availability configuration, you might experience unexpected behavior with the newly installed vCenter Single Sign-On instance.
