Before replacing the boot media in your ASA A20, ASA A30 or ASA A50 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 e0S (e0M wrench) port on the impaired controller is not faulty, and determining whether Onboard Key Manager (OKM) or External Key Manager (EKM) is enabled.

Requirements

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

  • The e0S (e0M wrench) port on the impaired controller cannot be faulty.

    The e0S port is used for automated boot recovery.

  • Determine if Onboard Key Manger (OKM) or Eternal Key Manager (EKM) is configured using one of the following methods:

    • You can ask the system administrator if OKM or EKM are enabled.

    • To check if OKM is enabled, you can use the security key-manager onboard show.

    • To check if EKM is enabled, you can use the security key-manager external show.

  • For OKM, you need the OKM passphrase file contents.

  • 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.

Considerations

  • It is important that you apply the commands in these steps on the correct controller:

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

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

  • If needed, you can turn on the platform chassis location (blue) LEDs to aid in physically locating the affected platform. Log into the BMC using SSH and enter the system location-led on command.

    A platform chassis has three location LEDs: one on the operator display panel and one on each controller. Location LEDs remain illuminated for 30 minutes.

    You can turn them off by entering the system location-led off command. If you are unsure if the LEDs are on or off, you can check their state by entering the system location-led show command.

What's next

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