Cisco IMC Release Number and .ISO Image Names

Beginning with the release 4.3, Cisco is updating the release number naming convention to align with the .ISO images.

Example: 4.3.1.YYXXXX

  • 4.3—Represents the main release.

  • .1—Represents the first release.

    For the current 4.3 main release, .1 represents the first release number.

    For subsequent maintenance releases, this number will represent the related maintenance release number.

  • YY—Represents the year of release.

    For the current 4.3 main release, 23 is derived from the year 2023.

  • XXXX—The final 4 digits represent the increasing sequence of build numbers every year.

    For the first 4.3 main release, the number is 0097.

Cisco IMC and Cisco UCS Manager Release Compatibility Matrix

Cisco UCS C-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, UCSM end-user interface is used to manage the server.

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

Upgrade and Downgrade Guidelines

To get a complete overview of all the possible upgrade paths in Cisco IMC, see Cisco UCS Rack Server Upgrade Support Matrix.

Downgrade Limitation for Release 4.3.3.240022:

In the release 4.3.3.240022, you cannot downgrade the Cisco UCS M7 servers with 5th Gen Intel® Xeon® processors.

When you try to downgrade Cisco IMC, the following error message is displayed on CLI, GUI, Redfish API and XML API user interfaces:

Error message during BMC downgrade with different interfaces like CLI/WEBUI/Redfish/XML =

“Update aborted. INCOMPATIBLE_IMAGE”

When you try to downgrade BIOS, the following error message is displayed on CLI, GUI, Redfish API and XML API user interfaces:

CPU ID mismatch between uploaded image and the platform.


Note

You can downgrade Cisco UCS M7 servers with 4th Generation Intel® Xeon® Scalable Processors.

Infrastructure Upgrade and Downgrade to Release 4.3(2):

  • Cisco UCS M4 servers are not supported by 4.3.2.230207 and later releases.

  • You must perform firmware update after adding any new hardware component to the system.

  • If you are planning to install Cisco UCS VIC 15237 or 15427 in a server, then upgrade the server to 4.3.2.230270 or later versions and then insert the adapter into the server.

    If you insert Cisco UCS VIC 15237 or 15427 into the server that is running earlier versions than 4.3.2.230270, then upgrade the server to 4.3.2.230270 or later versions and power cycle the server to recognize the adapter.

  • If you are planning to install Cisco UCS VIC 15235 or 15425 in a server, then upgrade the server to 4.3.2.230207 or later versions and then insert the adapter into the server.

    If you insert Cisco UCS VIC 15235 or 15425 into the server that is running earlier versions than 4.3.2.230207, then upgrade the server to 4.3.2.230207 or later versions and power cycle the server to recognize the adapter.

Support for Cisco UCS M7 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 4.3.

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

  • Broadcom Adapters

  • LAN on Motherboard

  • PCIe adapter firmware

  • HDD firmware

  • SAS Expander firmware

  • DCPMM Memory

  • PCI Gen5 retimer

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

Software Utilities

The following standard utilities are available:

  • Host Update Utility (HUU)

  • Server Configuration Utility (SCU)

  • Server Diagnostic Utility (SDU)

The utilities features are as follows:

  • Availability of HUU, SCU on the USB as bootable images. The USB also contains driver ISO, and can be accessed from the host operating system.

First Affected Release

CSCwi85031

In a Cisco UCS C240 M7 server equipped with 2 Intel Flex 170 GPUs placed on two Riser slots and dual socket server with CPU SKUs (with built-in single QAT, DLB, DSA, IAA accelerator devices) and running on Cisco UCS HUU 4.3.3 with RHEL 9.2 and Ubuntu 22.04.3, kernel panic and boot hang is observed.

By default, BIOS uses a lower MMIO base and size.

This causes an issue with the GPUs during PCI enumeration as Intel Flex 170 GPUs require higher range memory with more granularity size.

Perform the following steps:

  1. Login to the Cisco IMC Web UI as an admin user.

  2. In the Navigation pane, click the Compute menu.

  3. In the work pane, click the BIOS tab.

  4. In the Actions area, click Enter BIOS Setup.

  5. Click OK at the prompt.

    Enables Enter BIOS setup. On restart, the server enters the BIOS setup.

  6. Select BIOS Setup > Advanced > Socket Configuration > Uncore Configuration > Uncore General Configuration .

  7. Enter the value 1024G for the field MMIO High Granularity Size.

  8. Disable the LIMIT CPU PA to 46 Bits option.

  9. Enter the value 56Tfor the field MMIO High Base

  10. Press F10 to save your settings and reboot the server.
