Upgrading Cisco UCS Server Firmware with a Host Firmware Package

Describe firmware and software updates and their impacts on B-Series and C-Series servers
Answer Correct answer: C — Upgrade the server through the host firmware package bound to the service profile.

An engineer must upgrade the server firmware for which the service profile is configured with a host firmware package. Which action must be taken to accomplish this goal?

  1. Disassociate the service profile from the server and upgrade.
  2. Change the maintenance policy to user-ack and upgrade.
  3. Upgrade the server through the host firmware package. Correct Answer
  4. Perform a direct upgrade on the server using Auto Install.

Community Insight

The HFP is the single source of truth for server and adapter firmware versions. Changing the package (or its referenced firmware bundle) and re-applying the service profile stages and applies the firmware without breaking the server association.

A host firmware package (HFP) embedded in a service profile lets UCS Manager push BIOS and adapter/CIMC firmware to the associated server; you upgrade by updating the HFP, not by disassociating the profile or using Auto Install directly.

Engineers think they must disassociate the service profile (A) or use Auto Install directly (D). Disassociation is disruptive and unnecessary; Auto Install bypasses the managed, profile-bound firmware policy.

Agree with C: You can use firmware packages in service profiles to upgrade the server and adapter firmware, including the BIOS on the server, by defining a host firmware policy and including it in the service profile associated with a server.

Why the Answer Is Correct

With a host firmware package bound to the service profile, the supported method is to update the firmware via the host firmware package itself: change the package version / firmware bundle and re-acknowledge the service profile. UCS Manager then stages and applies the firmware to the server and adapters (including BIOS).

Why the Other Options Are Wrong

A. Disassociating the service profile is disruptive and not required to perform an HFP-based upgrade. B. A user-ack maintenance policy only governs how a disruptive change is applied; it is not the action that performs the upgrade. D. Auto Install performs a direct host image update that ignores the profile-bound HFP and is not how HFP-managed servers are upgraded.
