Shut down or take over the impaired controller.

If your storage system is running ONTAP 9.17.1 or later, use the automated boot recovery procedure. If your system is running an earlier version of ONTAP, you must use the manual boot recovery procedure.

Complete the shutdown of the impaired controller by halting it to the LOADER prompt and capturing the boot environment variables. The LOADER prompt is the safe halted state from which you can replace the boot media.

Steps

  1. Take the impaired controller to the LOADER prompt:

    If the impaired controller displays…​ Then…​

    The LOADER prompt

    Go to Remove controller module.

    Waiting for giveback…​

    Press Ctrl-C, and then respond y when prompted.

    System prompt or password prompt (enter system password)

    Take over or halt the impaired controller from the healthy controller: storage failover takeover -ofnode impaired_node_name

    When the impaired controller shows Waiting for giveback…​, press Ctrl-C, and then respond y.

  2. From the LOADER prompt, enter: printenv to capture all boot environmental variables. Save the output to your log file.

    Note This command may not work if the boot device is corrupted or non-functional.
