The Cisco C-Series Cisco Integrated Management Controller (CIMC) software delivers many new features and capabilities including enhancements to the Host Upgrade Utility (HUU). The Host Upgrade Utility enables users to update their CIMC, BIOS, LOM, RAID Controllers, PCI adapters and Cisco VIC cards from a single interface. In previous versions of HUU, an interactive menu-driven command line interface was the only option provided to update system BIOS, CIMC, adapter firmware, and LAN on Motherboard (LOM).
Enhancements to HUU include adding an interactive graphical user interface to HUU and adding non-interactive update capabilities for single-system and multiple-system updates for no touch upgrades of Cisco C-Series Server firmware. Updates can be applied using the bootable image in the HUU ISO which can be mounted via vMedia to boot host to HUU and triggered through the KVM using an interactive update interface. Other tools offering non-interactive updates include a Python update tool and a Microsoft Windows-based tool, both of which offering single-system and multi-system update capabilities.
The Host Update Utility (HUU) is a tool that helps users to update the various levels of firmware running on their system including:
CIMC
BIOS
LAN on Motherboard (LOM)
RAID Controllers
PCI Adapters
Cisco Virtual Interface Cards (VIC)
For more information on using the Interactive Utility or the Python Non-Interactive Utility, check out the Getting Started with HUU Guide available here.
In this video we will use the native utility to update a single system using vKVM attached media and the new HUU Graphical User Interface to update a single system.
In this video we will use the Python Tool to update a single system by passing configuration flags and options through the CLI to a remote target. This is the recommended update process for a one-time update to a single system.
In this video we will use the Python Tool to update a group of systems using a configuration file. We will walk through the encryption setup process for the target CIMC as well as the remote share and how to reference these encrypted files in an update script. This is the recommended update process for updating multiple systems concurrently.
****NOTE: For IMC 3.x and above, Python >= 2.7.9 and OpenSSL >= 1.0.1 are required. For IMC 4.1(3) and above, Python 3 is required.

Firmware update failed on server with CIMC IP (10.5.8.15)
Update Summary:
---------------
Firmware update failed for CIMC - 10.5.8.15, Error - Object of class huuFirmwareUpdater has incorrect DN (sys/huu/firmwareUpdater)
I'm hoping the community knows of this problem. In the meantime, I'll verify that the upgrade works through just CLI. I can automate the CLI as well, but I prefer the python/xmlrpc approach over expect.
Sorry for the issues here. Please refer to the v2 version of the tools posted above, as this should address the issues you had encountered. Also, please make use of the multiserver_config file when running upgrades across more than one system. Please let us know if you have any further questions!
I had high hopes for the python tools for exactly this use case (upgrading the firmware on many geographically dispersed ucs-e modules) but it seems it doesn't work out of the box.
After removing an option in the API call which apparently doesn't exist on E Series servers (updateType i think) i was able to start the script and test it with huu_3.1.3.iso.
It seemed to run fabulously, rebooted the server into the CIMC iso mounted from a www share without any intervention, but then it just sits at the EULA display and waits. IMHO the upgrade utility does not unterstand that it's supposed to run in unattended mode.
I would absolutely love to have the ability to upgrade the firmware on those server without touching every single one manually, it takes so much time and it's just busy work. It seems like there isn't a lot missing to make this happen, perhaps Cisco can provide an image which auto-accepts EULA? pinging grewilkijeffoste please consider this feature request.
OK - great. As mentioned in the notes, you need to use Python 2.7.9 or later. Also, please use the scripts for the release you are currently running. If you are running 3.0, you can use the 3.0(3) scripts. If you still have issues, please let me know.
