Description
Use this command to commit a firmware download to a CP. This command copies
an updated firmware image on the primary partition to the secondary partition and
commits both partitions of a CP to an updated version of the firmware. This must
be done after each firmwaredownload, and after the switch has been
rebooted and a sanity check is performed to make sure the new image is fine.
For switches which have flash memory set into two equal partitions, the primary
partition is the where the system boots from, the secondary partition is where a
copy of the firmware is stored, in case the primary partition is damaged.
To maintain the integrity of the firmware image in the flash memory, the
firmwaredownload command updates both partitions at once. When
firmwaredownload completes successfully and the CP is rebooted, the
system switches the primary partition (with the old firmware) to the secondary,
and the secondary partition (with the new firmware) to the primary.
The default behavior of the firmwaredownload command automatically
runs the firmwarecommit command after the reboot. For the cautious, the
firmwaredownload command has an option to disable auto-commit of the
new firmware. If you decide to disable the auto-commit option when running
firmwaredownload, then, after the CP is rebooted, you must execute one of
two commands:
■ Run the firmwarecommit command to copy the primary partition (with
new firmware) to the secondary, and commit the new firmware to both
partitions of the CP, or
