Requirements to replace the boot media - ASA C30

Before replacing the boot media in your ASA C30 storage system, ensure you meet the necessary requirements and considerations for a successful replacement. This includes verifying that you have the correct replacement boot media, confirming that the e0M (wrench) port on the impaired controller is working properly, and determining whether Onboard Key Manager (OKM) or External Key Manager (EKM) is enabled.

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.

  • You must replace the failed component with a replacement FRU component of the same capacity that you received from NetApp.

  • Verify that the e0S interface (e0M wrench port) on the impaired controller is not faulty.

    The e0M port is used to communicate between the two controllers during the automated boot recovery process.

  • For OKM, you need the cluster-wide passphrase and also the backup data.

  • For EKM, you need copies of the following files from the partner node:

    • /cfcard/kmip/servers.cfg file.

    • /cfcard/kmip/certs/client.crt file.

    • /cfcard/kmip/certs/client.key file.

    • /cfcard/kmip/certs/CA.pem file.

  • It is critical to apply the commands to the correct controller when you are replacing the impaired boot media:

    • The impaired controller is the controller on which you are performing maintenance.

    • The healthy controller is the HA partner of the impaired controller.

What's next

After you've reviewed the boot media requirements, you shut down the controller.
