Recovery from a failed reboot requires that you have access to the system via a console port, and have an uncorrupted copy of the StarOS boot image file stored in flash memory on the management card, or accessible from an external memory device.
Boot recovery can only be executed via a terminal connected to the serial console port on the active management card. This connection can be through a terminal server that is accessible via a LAN interface. Boot recovery can only be viewed via the console port.
The boot recovery command line interface enables you to specify from which boot image you would like to boot the system. If the system failed to reload following a software update, you can initiate a boot from a previously stored image.
The system recovery process will prompt you to enter the path name for the location of the StarOS boot image from which the system will boot. By default the boot command will timeout and attempt to reload the highest priority image from flash memory using the default configuration file.
- For StarOS releases prior to 16.1, the image filename is identified by its release version and corresponding build number. Format = production.build_number.platform.bin.
- For StarOS release 16.1 onwards, the image filename is identified by its platform type and release number. Format = platform-release_number.bin.
