Requirements for automatic boot media recovery - AFF C30 and AFF C60

Before replacing the boot media in your AFF C30 or AFF C60 storage system, ensure you meet the necessary requirements 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.

The automated boot media recovery process is supported only in ONTAP 9.17.1 and later. If your storage system is running an earlier version of ONTAP, use the manual boot recovery procedure.

Review the following requirements.

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

  • Verify that the e0M (wrench) port on the impaired controller is connected and 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.
