Shut down the impaired controller on an AFF C190 system after completing encryption checks. This procedure includes taking the controller to the LOADER prompt, capturing boot environmental variables for reference, and preparing the controller for boot media replacement.

The AFF C190 system supports only manual boot media recovery procedures. Automated boot media recovery is not supported.

After completing the NVE or NSE tasks, you need to complete the shutdown of the impaired controller.

Steps

  1. Take the impaired controller to the LOADER prompt:

    If the impaired controller displays…​ Then…​

    The LOADER prompt

    Go to Remove controller module.

    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.
