ServiceProfile Association
Duringthis stage, you include the firmware packages in a service profile, and then associate the service
profilewith a server. The system pushes the selected firmware versions to the endpoints. For a host
firmwarepackage, the server is rebooted to ensure that the endpoints are running the versions specified
inthe firmwarepackage.
Existing Service Profile
Ifthe service profile is already associated with a server, Cisco UCS Manager upgrades the firmware as soon
asyou savethe changesto thehost firmwarepackages. For a hostfirmware package, Cisco UCSManager
rebootsthe server as soon asthe change is saved.
Firmware Downgrades
Youdowngrade firmware in a Cisco UCS domain in the same way that you upgrade firmware. The package
orversion that you select when you update the firmware determines whether you are performing an upgrade
ora downgrade.
TheCisco UCS Manager GUI does not allow you to choose options that a release does not support. If a
CiscoUCS domain includes hardware that is not supported in the release to which you are downgrading,
CiscoUCS Manager GUI does not display the firmware as an option for that hardware or allow you to
downgradeto it.
Note
Completing the Prerequisites for Upgrading the Firmware

Prerequisites for Upgrading and Downgrading Firmware

Allendpoints in a Cisco UCS domain must be fully functional and all processes must be complete before you
begina firmware upgrade or downgrade on those endpoints.You cannot upgrade or downgrade an endpoint
thatis not in a functional state. For example, the firmware on a server that has not been discovered cannot be
upgradedor downgraded. An incomplete process, such as an FSM that has failed after the maximum number
ofretries, can cause the upgrade or downgrade on an endpoint to fail. If an FSM is in progress, Cisco UCS
Managerqueues up the update and activation and runs them when the FSM has completed successfully.
Coloredboxes around componentson theEquipment tab may indicatethat an endpoint on that component
cannotbe upgraded or downgraded.Verify the status of that component before you attempt to upgrade the
endpoints.
TheInstalled Firmware tab in Cisco UCS Manager GUI does not provide sufficient information to
completethese prerequisites.

Beforeyou upgrade or downgrade firmware in a Cisco UCS domain, complete the following prerequisites:
