7.1 Software Update Profile Specification

The Dell Common Information Model (CIM) class extensions for supporting BIOS, component firmware,

and embedded software update are defined in the Dell Software Update Profile

and related MOF files

The diagrams representing the classes that are implemented by the Lifecycle Controller firmware can be

found in Dell Software Update Profile as well.

7.2 ”Rollback” Firmware

The InstallFromSoftwareIdentity() method is used for installation of a earlier version of a component

firmware that is available on the Lifecycle Controller (that is “rollback” of component firmware). The

general “Rollback” firmware steps are performed in several stages as described in the next sections. The

tasks are demonstrated in examples in Section 7.3 and Section 7.4.

7.2.1 Request “Rollback” Image

The first stage is a request to initiate and download the rollback image from the Lifecycle Controller by

invoking the InstallFromSoftwareIdentity() method.

7.2.2 Create Reboot Job

The second stage is to create a reboot job as shown in Section 7.8.

7.2.3 Schedule Update Jobs

The third stage is to invoke the SetupJobQueue() method as shown in Section 10.2.1. Use the jobID(JID)

from InstallFromSoftwareIdentity() and rebootID(RID) from the reboot job. The reboot may take several

minutes as the UEFI performs the desired operation.

7.2.4 Monitor Update Jobs

The output of getting the job status during various steps, Section 10.2.3, is shown below.
