Upgrading Cisco UCS Server Firmware with a Host Firmware Package
Short answer
C Upgrade the server through the host firmware package bound to the service profile.
Question
Key Takeaways
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.
Common mistake: 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.
Expert Analysis
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.
