Upgrading the C-Series Server Firmware
If your server CIMC release version does not meet the requirement for integration with Cisco UCS Manager, make sure to upgrade the server firmware before connecting the server with Cisco UCS domain. For more information on upgrading the C-Series server firmware, see the host upgrade utility quick start guide for your release http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html

When you upgrade the C-Series server firmware for Cisco UCS C220 M4 or C240 M4 servers to Cisco UCS Manager 2.2(6c), you will see the following critical alarm:
This alarm, documented in CSCuv45173, is incorrectly categorized as a critical alarm. It does not impact the functionality of the server, and can be ignored. To avoid seeing this alarm, you can do one of the following:

Procedure
Step 1 |
Download the HUU ISO file:
|
||
Step 2 |
If you want to prepare the ISO for a local upgrade, complete this step; Otherwise, go to Step 3.
|
||
Step 3 |
Prepare the ISO for a remote upgrade using the KVM Console.
|
||
Step 4 |
Boot the server and press F6 when prompted to open the Boot Menu screen. |
||
Step 5 |
In the Boot Menu screen, choose the prepared ISO:
The server boots from the selected device. |
||
Step 6 |
After the HUU boots, Cisco End User License Agreement (EULA) appears, read the EULA and click:
After you accept the EULA, when the Cisco Host Upgrade Utility window appears with a list of all the components that are available for update. |
||
Step 7 |
If you want to update all the listed components, click Update all.
|
||
Step 8 |
If you want update specific components from the list, choose the components that you want to update. |
||
Step 9 |
Click Update.
This initiates the update and the status of the update is displayed in the Update Status column. You can also view a more detailed log of a series of activities and statuses that are involved while updating the firmware in the Execution Logs section. |
||
Step 10 |
If you want to update the firmware of the hard disk of a server, click Update HDD Firmware. A window displays a list of hard disk drives on the server that support new firmware. Hard disk drives that do not support firmware upgrades are not listed.
|
||
Step 11 |
Reboot the server. |
||
Step 12 |
Reboot the server, and click Last Update Verify to verify if the update was successfully completed. This action compares the previously updated firmware version for each component that was updated using the HUU with the current version of the firmware on the components and provides the status of the update. |
||
Step 13 |
If you want to save the log files of the update status for later use, click Save Logs. Log files that contain a detailed status of the update are saved to an external USB device that is connected to the server physically or through the KVM vMedia.
|
||
Step 14 |
Click Exit to exit from the HUU.

What to do next
After upgrading the server to the compatible server release version, you must establish the physical connection for the server to make it a part of Cisco UCS domain. To connect the server to your Cisco UCS FEXes and FIs, see .
