Requirements for automated boot media recovery - AFF A70 and AFF A90

Review the requirements before replacing the boot media in your AFF A70 or AFF A90 storage system, including cluster port functionality, key manager configuration, and ONTAP version compatibility.

The automated boot media recovery process requires ONTAP 9.17.1 or later. If your storage system runs 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

  • Understand the controller terminology used in this procedure:

    • 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.
