How to Update the Fallback Image

This procedure applies to those systems that have service processors (SPs) with the fallback miniroot installed. Whenever you update to an SRU version on the host, you must also update the fallback image.

Note - The fallback image's Readme file also provides the same instructions for updating the fallback image. Make sure to refer to that document for additional information related to the image.

Access your MOS account at https://support.oracle.com

On the support web page, search for Doc ID 2045311.1 (Oracle Solaris 11.3 Support Repository Updates (SRU) Index ).

This index lists the different SRU versions with links to their corresponding fallback boot images.

Download the SRU version's fallback image.

At the ILOM prompt, check the version of the current image to verify that you do not have the latest version installed already.

Code:
-> show /SP/firmware/host/miniroot version

  /SP/firmware/host/miniroot
    Properties:
        version = fallback-5.11-0.175.2.9.0.5.0

At the ILOM prompt, update the fallback image.

Code:
-> load -source  http://webserver.example.com/fallback/fallback.pkg

BOOTCTL(1)							      bootctl								BOOTCTL(1)

NAME
bootctl - Control the firmware and boot manager settings SYNOPSIS
bootctl [OPTIONS...] status bootctl [OPTIONS...] list bootctl [OPTIONS...] update bootctl [OPTIONS...] install bootctl [OPTIONS...] remove DESCRIPTION
bootctl checks, updates, installs or removes the boot loader from the current system. bootctl status checks and prints the currently installed versions of the boot loader binaries and all current EFI boot variables. bootctl list displays all configured boot loader entries. bootctl update updates all installed versions of systemd-boot, if the current version is newer than the version installed in the EFI system partition. This also includes the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is created if there is no current entry. The created entry will be added to the end of the boot order list. bootctl install installs systemd-boot into the EFI system partition. A copy of systemd-boot will be stored as the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is created and added to the top of the boot order list. bootctl remove removes all installed versions of systemd-boot from the EFI system partition, and removes systemd-boot from the EFI boot variables. If no command is passed, status is implied. OPTIONS
The following options are understood: -h, --help Print a short help text and exit. --version Print a short version string and exit. --path= Path to the EFI System Partition (ESP). If not specified, /efi, /boot, and /boot/efi are checked in turn. It is recommended to mount the ESP to /boot, if possible. -p, --print-path This option modifies the behaviour of status. Just print the path to the EFI System Partition (ESP) to standard output and exit. --no-variables Do not touch the EFI boot variables. EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise. SEE ALSO
