Transferring files to the boot media using backup recovery from the second boot media

You can install the system image to the replacement boot media using the image on second boot media installed in the controller module. This is the primary method for transferring the boot media files to the replacement boot media in systems with two boot media in the controller module.

About this task

The image on the secondary boot media must contain an image.tgz file and must not be reporting failures. If image.tgz file is missing or the boot media reports failures, you cannot use this procedure. You must transfer the boot image to the replacement boot media using the USB flash drive replacement procedure.

Steps

  1. If you are not already grounded, properly ground yourself.
  2. If you have not already done so, close the air duct:
    1. Swing the air duct all the way down to the controller module.
    2. Slide the air duct toward the risers until the locking tabs click into place.
    3. Inspect the air duct to make sure that it is properly seated and locked into place.

  3. Align the end of the controller module with the opening in the chassis, and then gently push the controller module halfway into the system.
  4. Reinstall the cable management device and recable the system, as needed.
    When recabling, remember to reinstall the media converters (SFPs) if they were removed.
  5. Recable the power supply, and then connect it to the power source.
    Make sure that you reattach the power cable locking collar on the power cord.
  6. Gently push the controller module all the way into the system until the controller module locking hooks begin to rise, firmly push on the locking hooks to finish seating the controller module, and then swing the locking hooks into the locked position over the pins on the controller module.
    The node begins to boot as soon as it is completely installed into the chassis.
  7. Interrupt the boot process by pressing Ctrl-C to stop at the LOADER prompt.
  8. From the LOADER prompt, boot the recovery image from the secondary boot media: boot_recovery
    The image is downloaded from the secondary boot media.
  9. When prompted, either enter the name of the image or accept the default image displayed inside the brackets on your screen.
  10. After the image is installed, start the restoration process:
    1. Record the IP address of the impaired node that is displayed on the screen.
    2. Press y when prompted to restore the backup configuration.
    3. Press y when prompted to confirm that the backup procedure was successful.
  11. From the partner node in advanced privilege level, start the configuration synchronization using the IP address recorded in the previous step: system node restore-backup -node local -target-address impaired_node_IP_address
  12. After the configuration synchronization is complete without errors, press y when prompted to confirm that the backup procedure was successful.
  13. Press y when prompted whether to use the restored copy, and then press y when prompted to reboot the node.
  14. Exit advanced privilege level on the healthy node.
