108 Using FTP to download logs and update firmware
Updating controller module firmware
A controller enclosure can contain one or two controller modules. In a dual-controller system, both
controllers should run the same firmware version. You can update the firmware in each controller module
by loading a firmware file obtained from the HP web download site, http://www.hp.com/go/msa
. To
install an HP ROM Flash Component or firmware Smart Component, follow the instructions on the HP web
site; otherwise, to install a firmware binary file, follow the steps below.
If you have a dual-controller system and the Partner Firmware Update option is enabled, when you update
one controller the system automatically updates the partner controller. If Partner Firmware Update is
disabled, after updating software on one controller you must manually update the partner controller.
To update controller module firmware
1. Obtain the appropriate firmware file and download it to your computer or network.
2. In SMU, prepare to use FTP:
a. Determine the network-port IP addresses of the system’s controllers.
b. Verify that the system’s FTP service is enabled.
c. Verify that the user you will log in as has permission to use the FTP interface.
3. If the system has a single controller, stop I/O to vdisks before starting the firmware update.
4. Open a Command Prompt (Windows) or a terminal window (UNIX) and navigate to the directory
containing the firmware file to load.
5. Enter:
ftp controller-network-address
For example:
ftp 10.1.0.9
6. Log in as an FTP user.
7. Enter:
put firmware-file flash
For example:
put mercurysw-M100P01-01.bin flash
It takes approximately 10 minutes for the firmware to load and for the automatic restart to complete on
the controller you are connected to. Wait for progress messages to specify that the update has
completed. If Partner Firmware Update is enabled, allow an additional 20 minutes for the partner
controller to be updated. No messages are displayed in the FTP interface while the partner is being
updated.
WARNING! Do not perform a power cycle or controller restart during a firmware update. If the
update is interrupted or there is a power failure, the module might become inoperative. If this
occurs, contact technical support. The module might need to be returned to the factory for
reprogramming.
NOTE: If you attempt to load an incompatible firmware version, the message ***Code Load
Fail. Bad format image.*** is displayed and after a few seconds the FTP prompt is
redisplayed. The code is not loaded.
