CIMC Firmware Management

CIMC Firmware Management

This chapter includes the following sections:

Overview of Firmware

C-Series servers use Cisco-certified firmware specific to the C-Series server model that you are using. You can download new releases of the firmware for all supported server models from Cisco.com.


Caution


When you install new BIOS firmware, it must be from the same software release as the CIMC firmware running on the server. Do not install new BIOS firmware until after you have activated the matching CIMC firmware or the server will not boot.

To avoid potential problems, we strongly recommend that you use the Cisco Host Upgrade Utility (HUU), which upgrades the BIOS, CIMC, and other firmware to compatible levels. For detailed information about this utility, see the Cisco Host Upgrade Utility Guide for the version of the HUU that goes with the CIMC software release that you want to install. The HUU guides are available at the following URL: http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html.


If you elect to update the firmware manually, you must update the CIMC firmware first. The CIMC firmware update process is divided into the following stages to minimize the amount of time the server will be offline:

  • Installation. During this stage, CIMC installs the selected CIMC firmware in the non-active, or backup, slot on the server.
  • Activation. During this stage, CIMC sets the non-active firmware version as active and reboots the server, causing a disruption in service. When the server reboots, the firmware in the new active slot becomes the running version.

After you activate the CIMC firmware, you can update the BIOS firmware. The server must be powered off during the entire BIOS update process, so the process is not divided into stages. Instead, you only need to issue a single command and CIMC installs and updates the BIOS firmware as quickly as possible. Once the CIMC finishes rebooting, the server can be powered on and returned to service.


Note


You can either upgrade an older firmware version to a newer one, or downgrade a newer firmware version to an older one.


Obtaining Firmware from Cisco

Procedure
    Step 1   Navigate to http://www.cisco.com/.
    Step 2   If you are not already logged in, click Log In at the top right-hand edge of the page and log in using your Cisco.com credentials.
    Step 3   In the menu bar at the top, click Support.
    Step 4   Click All Downloads in the roll down menu.
    Step 5   If your server model is listed in the Recently Used Products list, click the server name. Otherwise, do the following:
    1. In the left-hand box, click Products.
    2. In the center box, click Unified Computing and Servers.
    3. In the right-hand box, click Cisco UCS C-Series Rack-Mount Standalone Server Software.
    4. In the right-hand box, click the server model whose software you want to download.
    Step 6   Click the Unified Computing System (UCS) Server Firmware link.
    Step 7   (Optional)Select a prior release from the menu bar on the left-hand side of the page.
    Step 8   Click the Download button associated with the Cisco Host Upgrade Utility ISO for the selected release.
    Step 9   Click Accept License Agreement.
    Step 10   Save the ISO file to a local drive.

    We recommend you upgrade the CIMC and BIOS firmware on your server using this ISO file, which contains the Cisco Host Upgrade Utility. For detailed information about this utility, see the Cisco Host Upgrade Utility Guide for the version of the HUU that goes with the CIMC software release that you want to install. The HUU guides are available at the following URL: http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html.

    Step 11   (Optional) If you plan to upgrade the CIMC and BIOS firmware manually, do the following:
    1. From the ISO file, open the ZIP file containing the firmware installation files.

      The ZIP file is on the top-level of the ISO file, and its name follows the format ServerModel_ReleaseNumber.ZIP.

      For example, C240M3_1.4.4A.ZIP.

      You do not need to extract all of the files contained in this ZIP file. Instead, you only need to open it so that you can access the BIOS firmware installation CAP file and the ZIP file containing the CIMC firmware installation BIN file.

    2. From the ServerModel_ReleaseNumber.ZIP file, extract the BIOS firmware installation CAP file and save it to your local drive.

      The CAP file is in the ReleaseNumber/bios/cimc folder, and its name follows the format Server-BIOS-Release-Number.CAP.

      For example, 1.4.4a/bios/cimc/C240-BIOS-1-4-4c-0.CAP.

    3. From the ServerModel_ReleaseNumber.ZIP file, open the ZIP file containing the CIMC firmware installation files.

      The ZIP file is in the ReleaseNumber/cimc folder and its name follows the format server-model-cimc-release.zip.

      For example, 1.4.4a/cimc/c240-m3-cimc.1.4.4a.zip.

      You do not need to extract all of the files contained in this zip file. Instead, you only need to open it so that you can access the CIMC firmware installation BIN file.

    4. From the server-model-cimc-release.zip file, extract the full CIMC firmware installation BIN file and save it to your local drive.

      The BIN file is in the server-model-cimc-release folder and its name follows the format upd-pkg-server-model-cimc.full.release.bin.

      For example, c240-m3-cimc.1.4.4a/upd-pkg-c240-m3-cimc.full.1.4.4a.bin.

    Step 12   (Optional)If you plan to install the firmware from a TFTP server, copy the BIOS installation CAP file and the CIMC installation BIN file to the TFTP server you want to use.

    The server must have read permission for the destination folder on the TFTP server.
