/cx update fw=filename_with_path [force]
This command is only for 9000 series controllers.
This command allows the downloading of the specified firmware image to the corresponding controller.
Note: Before issuing this command, you must have already obtained the firmware image and placed it on your system. You can obtain the firmware image from the 3ware website: http:www.3ware.com/downloads.
 
Important: Before you update the firmware on your controller, please follow these recommendations:
fw=filename_with_path attribute allows you to specify the firmware image file name along with its absolute path.
Note: filename_with_path must not have spaces in the directory names of its path (as Windows allows).
The new image specified by this filename_with_path is checked for compatibility with the current controller, current driver, and current application versions. A recommendation is then made as to whether an update is needed, and you are asked to confirm whether you want to continue. If you confirm that you want to continue, the new firmware image is downloaded to the specified controller.
A reboot is required for the new firmware image to take effect.
 
Note: The prom image number will vary for different controllers. Prom0006 is for the 9650SE and prom0008 is for the 9690SA.
Example:
 //localhost> /c0 update fw=/tmp/prom0006.img
Warning: Updating the firmware can render the device driver and/or management tools incompatible. Before you update the firmware, it is recommended that you:
 
1) Back up your data.
2) Make sure you have a copy of the current firmware image so that you can roll back, if necessary.
3) Close all applications.
