Before replacing the boot media in your AFF A20, AFF A30, or AFF A50 system, ensure you meet the necessary requirements for a successful replacement. This includes making sure you have a USB flash drive with the appropriate amount of storage and verifying that you have the correct replacement boot device.

Before replacing the boot media, make sure to review the following requirements and considerations.

Requirements

  • You must have a USB flash drive, formatted to FAT32, with the appropriate amount of storage to hold the image_xxx.tgz.

  • You must copy the image_xxx.tgz file to the USB flash drive for later use in this procedure.

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

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 requirements to replace the boot media, you need to check encryption key support and status on the boot media.
