You can restore a malfunctioning primary instance by promoting a replica instance to become the primary instance.

Promoting a replica instance restores the primary instance more quickly than replacing the primary instance with a new appliance, but the replica instance available for promotion needs to be physically accessible to an Operations Console administrator to facilitate ongoing administration.

Promoting a replica instance to be the primary instance changes the topology of a deployment in the following ways:

  • The malfunctioning primary instance is deleted from the deployment.

  • The promoted replica instance becomes the new primary instance.

  • The RADIUS server on the new primary instance becomes the RADIUS primary. You cannot perform a separate promotion of a replica RADIUS server.

  • If web tiers are associated with the old primary instance, you must restart the web tiers that are associated with the old primary instance.

  • If web tiers are associated with any replica instance in the deployment, you must restart the web tiers that are associated with any replica instance.
