Requirements for automated boot media recovery - AFF C80

Before replacing the boot media in your AFF C80 storage system, ensure you meet the necessary requirements for a successful replacement. This includes verifying that you have the correct replacement boot media, confirming the cluster ports on the impaired controller are 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 boot media with a replacement boot media you received from NetApp.

  • The cluster ports are used to communicate between the two controllers during the automated boot recovery process. Make sure that the cluster ports on the impaired controller are working properly.

  • 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

    • /cfcard/kmip/certs/client.crt

    • /cfcard/kmip/certs/client.key

    • /cfcard/kmip/certs/CA.pem

  • 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.
