Enabling HA mode capability and controller failover

The HA license is no longer required in Data ONTAP 8.2. You must manually configure each node to enable or disable HA pair (high-availability) mode capability and controller failover.

Steps

  1. Enter the following command on each of the node consoles to enable HA mode capability:
    options cf.mode ha
  2. Enter the following command on each of the node consoles to reboot the nodes:
    reboot
  3. Enter the following command on either of the node consoles to enable controller failover:
    cf enable
  4. Verify that controller failover is enabled by entering the following command on each node console:
    cf status

    The system displays the following output if controller failover is enabled:

    Controller Failover enabled, node2 is up.
