Cisco UCS C-Series and Cisco UCS Manager Release Compatibility Matrix for C-Series Rack-Mount Servers

Cisco UCS C-Series Rack-Mount Servers are managed by built-in standalone software — Cisco Integrated Management Controller (Cisco IMC). However, when a C-Series Rack-Mount Server is integrated with Cisco UCS Manager, the Cisco IMC does not manage the server anymore.

The following table lists the C-Series software standalone and Cisco UCS Manager releases for C-Series Rack-Mount Servers:

Utilities

Note

Always upgrade the BIOS, the Cisco IMC and CMC from the HUU ISO. Do not upgrade individual components (only BIOS or only Cisco IMC), since this could lead to unexpected behavior. If you choose to upgrade BIOS, and the Cisco IMC individually and not from the HUU ISO, make sure to upgrade both Cisco IMC, and BIOS to the same container release. If the BIOS and the Cisco IMC versions are from different container releases, it could result in unexpected behavior. Cisco recommends that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS, and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together.

Host Upgrade Utility

The Cisco Host Upgrade Utility (HUU) is a tool that upgrades the Cisco UCS C-Series firmware.

The image file for the firmware is embedded in the ISO. The utility displays a menu that allows you to choose which firmware components to upgrade. For more information on this utility see:

http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html

For details of firmware files in Cisco Host Upgrade Utility for individual releases, see Cisco UCS C-Series Integrated Management Controller Firmware Files, Release 4.0

Updating the Firmware

Use the Host Upgrade Utility to upgrade the C-Series firmware. Host Upgrade Utility can upgrade the following software components:

  • BIOS

  • Cisco IMC

  • CMC

  • Cisco VIC Adapters

  • LSI Adapters

  • LAN on Motherboard

  • PCIe adapter firmware

  • HDD firmware

  • SAS Expander firmware

All firmware should be upgraded together to ensure proper operation of your server.


Note

We recommend that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together. Click Exit once you deploy the firmware.

For more information on how to upgrade the firmware using the utility, see:

Supported Features

Supported Features

The following new software features are supported in Release 4.0(1a):

  • Device Connector Updates—The following updates were added:

    • Added support to configure the C-Series servers using only Cisco Intersight. This option enables you to manage the server configuration either by using both Cisco IMC and Cisco Intersight or by using only Cisco Intersight.

    • Device ID and Claim Code fields were added to the Connections area.

  • Network Adapter Updates—Following changes were added:

    • General Adapter Properties Changes:

      Port Channel—Added an option to enable port channel. When this option is enabled two vNICs and two vHBAs are available for use on the adapter card. When disabled, four vNICs and four vHBAs are available.

    • Port Channel Capable—Added a field that indicates the port channel support on the adapter.

    • External Ethernet Interface changes:

      Admin FEC Mode—Added an option to set the Admin Forward Error Correction (FEC) mode.


      Note

      FEC mode is applicable only for 25G link speed. On the 14xx adapters, FEC mode set on the adapter must match the FEC mode of the switch. Otherwise the link does not work.

    • Operating FEC Mode—Added an option to display the Operating Forward Error Correction (FEC) mode.

  • BIOS Activation Updates— Added support to activate BIOS when the host is ON. A cancel BIOS activation feature to cancel a pending BIOS activation was also added.

  • Security Configuration Updates —Added an option to enable Common Criteria (CC).

  • Flexutil Virtual Drives Updates—Added the Resident Image field that displays the name of the image file present in the virtual drive.

  • XML API Updates—Added XML API support for Cisco Intersight device connector, Port Channel, Port Channel Capable, Admin FEC Mode and Operating FEC Mode.

  • Audit Log Updates—An audit log is generated with the details (changes performed, user details and the interface used) of the configuration changes done on a UCS C-Series server using Cisco IMC.

  • PXE IPv6 Support—Cisco UCS C-Series and S-Series M4 servers now support IPv6 option on PXE boot devices.


    Note

    This option is supported on the C-Series M5 servers from release 3.1(2) and S-Series (S3260 M5) from release 3.1(3).
