Update the Stage 3 Boot Loader and System Image
Whenever you upgrade the software image, upload the stage 3 boot loader image file and reboot the system with the new system software image. The stage 3 boot loader is backward compatible as well, so you can still boot into older software images with a newer stage 3 boot loader.
To ensure compatibility, copy the stage 3 boot loader to
/boot/bootloader
before you update the boot parameters to use the new software image file. The boot loader file must be renamed to
/boot/bootloader
on the target system with no file extension. When upgrading an HA pair, you must perform the upgrade procedure on each HA node.
Procedure
- Obtain the stage 3 boot loader image file (*.boot).
-
Upload the stage 3 boot loader image file (*.boot) as
/boot/bootloader
to your system using an SSH File Transfer Protocol (SFTP) client. - Upload the new system software image (*.bz) to /boot/.
