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.

Note

NetApp strongly recommends that you enable console logging on the devices you are working with and take the following actions when performing this procedure:

  • Leave AutoSupport enabled during your maintenance. This allows NetApp support to receive diagnostic information if issues occur.

  • Enable session logging for any CLI sessions. This creates a complete record of all commands and system output during the maintenance activity. For guidance on how to enable session logging, see How to configure PuTTY for optimal connectivity to ONTAP systems.

  • 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.
