Commits switch firmware.
Synopsis
firmwarecommit
Availability
admin
Description
Use this command to commit a firmware download to a CP. This command copies an updated firmware
image to the secondary partition and commits both partitions of the CP to an updated version of the
firmware. This must be done after each firmware download and after the switch has been rebooted and a
sanity check is performed to make sure the new image is fine.
For switches that 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 the secondary partition only. 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 is to automatically run the
firmwareCommit command after the reboot. If you decide to disable the autocommit option when
running firmwareDownload, after the CP is rebooted, you must execute one of two commands:
• firmwareCommit copies the primary partition (with new firmware) to the secondary and commits the
new firmware to both partitions of the CP.
• firmwareRestore copies the secondary partition (with the old firmware) to the primary and backs
out of the new firmware download. The firmwareRestore command can be run only if autocommit
was disabled during the firmware download. Autocommit can be disabled only when you run
firmwareDownload in single mode.
