Ensuring hardware-level HA is enabled

If the newly installed controller modules are reused—not new—you must enter Maintenance mode and ensure that their HA state is set to HA.

About this task

If you are using new controller modules, you can skip this procedure because HA is enabled by default. Otherwise, you must perform this procedure on both the nodes.

Steps

  1. On the first node, enter Maintenance mode:
    1. Exit the nodeshell by entering halt.
      The LOADER prompt is displayed.
    2. Enter Maintenance mode by entering boot_ontap maint.
      After some information is displayed, the Maintenance mode prompt is displayed.
  2. In Maintenance mode, ensure that the controller module and chassis are in HA state:
    1. Display the HA state of the controller module and chassis by entering ha-config show.
    2. If the displayed state of the controller is not HA, enter ha-config modify controller ha.
    3. If the displayed state of the chassis is not HA, enter ha-config modify chassis ha.
    4. Verify that HA is enabled on both the controller module and chassis by entering ha-config show.
  3. Return to ONTAP:
    1. Enter halt to exit Maintenance mode.
    2. Boot ONTAP by entering boot_ontap
    3. Wait while the node boots and the Cluster Setup wizard automatically starts on the console.
    4. Press Enter four times to accept the existing settings for the node-management LIF.
    5. Log in to the node as the admin user, which does not require a password.
  4. Repeat this procedure on the other node that you are adding to the cluster.
