Configuring the ONTAP Mediator service from a MetroCluster IP configuration

Download PDF of this page

The ONTAP Mediator service must be configured on the ONTAP node for use in a MetroCluster IP configuration.

Before you begin

  • The ONTAP Mediator must have been successfully installed on a network location that can be reached by both MetroCluster sites.

  • You must have the IP address of the host running the ONTAP Mediator service.

  • You must have the username and password for the ONTAP Mediator service.

  • All nodes of the MetroCluster IP configuration must be online.

About this task

  • This task enables automatic unplanned switchover by default.

  • This task can be performed on the ONTAP interface of any node in the MetroCluster IP configuration.

  • A single installation of the ONTAP Mediator service can be configured with up to five MetroCluster IP configurations.


  1. Add the ONTAP Mediator service to ONTAP using the following command: metrocluster configuration-settings mediator add -mediator-address ip-address-of-mediator-host

    Note: You will be prompted for the username and password for the Mediator admin user account.

  2. Verify that the automatic switchover feature in enabled: metrocluster show

  3. Verify that the Mediator is now running.
