This procedure enables you to perform a firmware download on each CP and verify that the
procedure was successful before committing to the new firmware. The old firmware is saved in the
secondary partition of each CP until you enter the firmwareCommit command. If you decide to back
out of the installation prior to the firmwareCommit, you can enter the firmwareRestore command to
restore the former active Fabric OS firmware image.
The firmwareRestore command can only run if autocommit was disabled during the
firmwareDownload. This command cannot be used to restore SAS and SA images.
NOTE
Brocade recommends that, under normal operating conditions, you maintain the same firmware
version on both CPs, and on both partitions of each CP. This procedure enables you to evaluate
firmware before you commit. As a standard practice, you should not run mixed firmware levels on
CPs.
