After completing the hardware replacement, you verify the low-level system configuration of the replacement controller and reconfigure system settings as necessary.

Step 1: Verify HA config settings

You must verify the HA state of the controller module and, if necessary, update the state to match your 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 module does not match your system configuration, set the HA state for the controller module: ha-config modify controller ha-state

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

    • ha

    • mcc (not supported)

    • mccip (not supported in ASA systems)

    • 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 with the storage show disk -p.

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

  2. Exit Maintenance mode: halt.
