About This Firmware Upgrade
This Cisco Integrated Management Controller (CIMC) upgrade procedure is supported on M4 and M5 hardware, when running Cisco Secure Workload version 3.6 or later or Cisco Tetration version 3.4 or later.
The Cisco Secure Workload/Tetration physical appliance bundles a Unified Computing System (UCS) CIMC Host Upgrade Utility (HUU) ISO image. The firmware upgrade option on the Secure Workload/Tetration Cluster Status page can be used to update a physical bare-metal installation to the version of UCS firmware included in the HUU ISO image bundled in the Secure Workload/Tetration RPM files.
For information about new and changed features in each CIMC version, see the applicable release notes available from https://www.cisco.com/c/en/us/support/servers-unified-computing/ucs-c-series-integrated-management-controller/products-release-notes-list.html.

Firmware Upgrade Procedure
Note |
In this process and document, "upgrade" and "update" are used interchangeably. |
Before you begin
-
Upgrade Cisco Secure Workload before upgrading CIMC.
-
Only one bare-metal host can have its UCS firmware updated at a time.
-
Before starting the firmware update, verify that all services are healthy:
In Secure Workload 3.6.x: Choose Troubleshoot > Service Status.
In Tetration 3.4.x or 3.5.x: Choose Maintenance > Service Status.
-
A firmware update on a bare-metal host can be initiated when the status is
Active
orInactive
, but not when the bare-metal host state isInitialized
orSKU Mismatch
. -
In order to start the firmware update, the Orchestrator State on the Cluster Status page must be
Idle
.
Procedure
Step 1 |
In the Secure Workload/Tetration web interface, navigate to the Cluster Status page: In Secure Workload 3.6.x: Choose Troubleshoot > Cluster Status In Tetration 3.4.x or 3.5.x: Choose Maintenance > Cluster Status |
Step 2 |
Choose Firmware upgrade from the Select action drop-down menu. |
Step 3 |
Select the bare-metal host to be updated and click Apply. When you initiate a firmware update, the installer will verify that the update can continue, gracefully shut down the bare-metal host if needed, and then start the upgrade. The overall update process can take two or more hours for M4 hardware, or one or more hours for M5 hardware. The following behaviors are temporary and expected:
After the firmware update is completed, it may take an additional 30 minutes for the bare-metal host to become active in the cluster again, and additional time may be needed for all services to become healthy again. If services do not recover within two hours following a firmware update, please contact Cisco TAC for assistance. |
Step 4 |
To view details about a bare-metal host, click a bare-metal host in the list on the Cluster Status page. Once a firmware update is initiated, you can click the View Firmware Upgrade Logs button to view the status of the firmware update. This log will display the overall status of the firmware update at the very top of the listing; this status entry will be one of the following:
To refresh the status view, close the upgrade status window and then click the View Firmware Upgrade Logs button again. Below the overall status in the View Firmware Upgrade Logs pop-up window, an Update progress section provides time-stamped log messages indicating the progress of the firmware update. Once the Rebooting Host In Progress status is displayed in these log messages, CIMC is in control of the update and the cluster is monitoring that update—most subsequent log messages come directly from CIMC and are only added to the list of log messages if the status of the update changes. Below the Update progress section of the View Firmware Upgrade Logs pop-up window, a Component update status section will be shown once CIMC starts providing individual component updates. This section can give a quick overview of the status of the update of the various UCS components on the bare-metal host. |
