Restoring and verifying the system configuration

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



  1. Verifying and setting the HA state of the controller module
    You must verify the HA state of the controller module and, if necessary, update the state to match your system configuration.
  2. Running system-level diagnostics
    You should run comprehensive or focused diagnostic tests for specific components and subsystems whenever you replace the controller.
