Requirements to replace the boot media - ASA A1K

Before replacing the boot media in your ASA A1K 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.

Review the following requirements.

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 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.
