Verify that the controller's HA configuration is active and functioning correctly in your AFF A70 or AFF A90 storage system, and confirm that the system's adapters list all the paths to the disks.

Verify the HA configuration settings and disk list before returning the system to service.

Steps

  1. Boot to maintenance mode:

    boot_ontap maint

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

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

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

    Note If you see PERSONALITY MISMATCH contact customer support.

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

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

    ha-config show

    The HA state should be the same for all components.

  6. 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

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

    • ha

    • mcc (not supported)

    • mccip (not supported in ASA systems)

    • non-ha (not supported)

  7. Confirm that the setting has changed:

    ha-config show

  8. Verify that the adapter lists the paths to all disks: storage show disk -p

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

  9. Exit Maintenance mode: halt

What's next?

After you’ve restored and verified the system configuration for your AFF A70 or AFF A90 system, you need to give back the controller.
