# Updating the Controller Firmware

The LSI Storage Authority software enables you to update the controller firmware.

Note:

LSA does not support downgrading of firmware from one phase to another phase on IT/IR controllers. However, LSA supports downgrading of firmware within the same phase.

For more information, see the LSA Readme that has been provided along with your package.

Note: On VMware ESXi 5.5, VMware ESXi 6.0, and VMware ESXi 6.5 platforms, you cannot update the firmware for IT/IR controllers through LSI Storage Authority due to a limitation with VMware.

To work around this issue:

1. Edit `/etc/sfcb/sfcb.cfg`
2. Add `httpMaxContentLength: 4194304`
3. Restart the LSA service `/etc/init.d/sfcbd-watchdog restart`
4. Now flash the firmware.

Also refer to the LSA Readme that has been provided along with the package for a more detailed information.

Perform the following steps to update the controller firmware.

1. Navigate to the Controller dashboard.
2. Click Update Firmware.
   The Update Firmware window appears. It displays the current controller firmware version.
3. Click Browse to locate and open the:

   - .bin update file for IR3/IT controllers.

4. Click Update.

   The Update Firmware windows displays the current controller firmware version and the controller firmware version that is selected to be flashed.

5. Select the Confirm check box and click Flash Firmware.

   After the update is complete, a message is displayed that confirms the success of the update and displays the new version of the controller firmware.

   Note:

   User updates to the firmware might cause a flash error event. Ignore the error message.

   When flashing IT firmware, BIOS, or UFI, LSA displays a message to reboot the server no matter the firmware version.
