Deprecation Notice

The 56-bit symmetric block cipher Data Encryption Standard (DES), used for secure communication of SNMP v3 notifications to the NMS (Network Monitoring System) of the user, is no longer considered sufficiently secure and does not meet the security baseline for UCS products. Therefore, DES will be deprecated as a configurable option (privacy type) for SNMP v3 users in future releases of Cisco IMC Software, starting with the upcoming 4.1(3) version release. However, DES will continue to be made available as a configurable encryption option (privacy type) for SNMP v3 users running previous Cisco IMC Software versions.

Cisco IMC and Cisco UCS Manager Release Compatibility Matrix

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

The following table lists the supported platforms, Cisco IMC releases, and Cisco UCS Manager releases for Rack-Mount Servers:

Hardware and Software Interoperability

For detailed information about storage switch, operating system and adapter, see the Hardware and Software Interoperability Matrix for your release located at:

http://www.cisco.com/en/US/products/ps10477/prod_technical_reference_list.html


Note

Connectivity is tested between the server and the first connected device. Further connections, such as to storage arrays after a switch are not listed in the Cisco UCS Hardware Compatibility List though they may be highlighted in the vendor support matrix for those devices.

Upgrade Paths to Release 4.1

The section provides information on the upgrade paths to release 4.1.


Important

While upgrading Cisco UCS C220 M5, C240 M5 or C480 M5 servers to release 4.1 under the following conditions:

  • if you are upgrading from any release earlier than 4.0(4)

  • if Legacy Boot Mode is enabled and no Cisco IMC Boot Order is configured

  • and, if the server is booting from Cisco HWRAID adapter


then, you should perform one of the following before upgrading:

Refer to the table for upgrade paths for various Cisco UCS C-series IMC versions.

Table 14. Upgrade Paths to Release 4.1

Upgrade From Release

Upgrade To Release

Recommended Upgrade Path

All M4 and M5 Servers from 4.0

4.1

Follow below upgrade path:

  • You can use Interactive HUU or Non-Interactive HUU (NIHUU) script to update the server.

  • While updating the firmware using the NIHUU tool, use the Python scripts that are released with version 4.1(2a).

  • Use OpenSSL 1.0.1e-fips on the client side (where the NIHUU python scripts are running).

  • Download HUU iso from here.

  • Download NIHUU script from here.

All M5 Servers from 3.1

4.1

Follow below upgrade path:

  • You can use Interactive HUU or NIHUU script to update the server.

  • While updating the firmware using the NIHUU tool, use the Python scripts that are released with version 4.1(2a).

  • Use OpenSSL 1.0.1e-fips on the client side (where the NIHUU python scripts are running).

  • Download HUU iso from here.

  • Download NIHUU script from here.

Firmware Upgrade Details

Firmware Files

For details of Unified Computing System (UCS) Server Firmware, drivers, and utilities for release 4.1(2), seeCisco UCS C-Series Integrated Management Controller Firmware Files, Release 4.1.


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 4.1.

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

  • DCPMM Memory

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


Note

We recommend that you use the select all and Update or Update & Activate 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:

http://www.cisco.com/c/en/us/support/servers-unified-computing/ucs-c-series-rack-servers/products-user-guide-list.html

Downgrade Limitation

Downgrade Limitation for Cisco UCS C125 M5 Servers

Release 4.1(2e) introduces AMD Platform Secure Boot (PSB) in Cisco UCS C125 M5 servers that implements hardware-rooted boot integrity. Once you upgrade to release 4.1(2e) or later, you cannot:
