Before replacing the controller in your AFX 1K storage system, ensure you meet the necessary requirements for a successful replacement. This includes verifying all other components in the system are functioning properly, verifying that you have the correct replacement controller, and saving the controller's console output to a text log file.

Review the requirements for replacing the controller.

  • It is important that you apply the commands in these steps on the correct systems:

    • The impaired controller is the controller that is being replaced.

    • The replacement controller is the new controller that is replacing the impaired controller.

    • The healthy controller is the surviving controller.

  • All drive shelves must be working properly.

  • The healthy controller must be able to take over the controller that is being replaced (referred to in this procedure as the “impaired controller”).

  • You must replace the failed component with the field-replaceable unit (FRU) you received from NetApp.

  • You must replace a controller module with a controller module of the same model type. You cannot upgrade your system by just replacing the controller module.

  • You cannot change any drives or drive shelves as part of this procedure.

  • You must always capture the controller's console output to a text log file.

    This provides you a record of the procedure so that you can troubleshoot any issues that you might encounter during the replacement process.
