Verify that the controller’s HA configuration is active and functioning correctly in your AFF A20, AFF A30, or AFF A50 storage system, and confirm that the system’s adapters list all the paths to the disks.

Step 1: Verify HA config settings

You must verify the HA state of the controller and, if necessary, update the state to match your storage system configuration.

  1. Boot to maintenance mode:

    boot_ontap maint

    1. Enter y when you see Continue with boot?.

      If you see the System ID mismatch warning message, enter y.

  2. Enter sysconfig -v and capture the display contents.

    Note If you see PERSONALITY MISMATCH contact customer support.

  3. From the sysconfig -v output, compare the adapter card information with the cards and locations in the replacement controller.

  4. Verify that all components display the same HA state:

    ha-config show

    The HA state should be the same for all components.

  5. If the displayed system state of the controller does not match your storage system configuration, set the HA state for the controller:

    ha-config modify controller ha-state

    The value for HA-state can be one of the following:

    • ha

    • non-ha (not supported)

  6. Confirm that the setting has changed:

    ha-config show

Step 2: Verify disk list

  1. Verify that the adapter lists the paths to all disks:

    storage show disk -p

    If you see any issues, check cabling and reseat cables.

  2. Exit Maintenance mode:

    halt

What's next?

After you’ve restored and verified the system configuration for your AFF A20, AFF A30, or AFF A50 system, you need to give back the controller.
