Scheduling Remote Update

The remote update scheduling capability provides the ability to schedule or

stage firmware updates now or in the future. Updates for Diagnostics and

USC can be performed directly and do not require any staging. These updates

will be applied as soon as they are downloaded and do not need the Job

Scheduler. All other remote updates are staged updates, and require

scheduling, using different scheduling options. The DUPs are downloaded to

the Lifecycle Controller and staged, and the actual update is performed by

rebooting the system into UEFI System Services.

There are multiple options for scheduling updates:

• Run updates on the desired components at a desired time.

• Run the reboot command to get a reboot job ID.

• Check on the status of any of the jobs by enumerating

DCIM_SoftUpdateConcreteJob instances and checking the

JobStatus

property value.

• Schedule the job using the

SetupJobQueue

() method on the

DCIM_JobService.

NOTE: For Remote Services version 1.3 remote updates, you can only use the

SetupJobQueue() method.

• Delete existing jobs using the

DeleteJobQueue()

method on the

DCIM_JobService.

Important

USC, Diagnostics and Driver Pack updates cannot be rolled back.

Rolling Back to Previous Versions

Use the InstallFromSoftwareIdentity() method to reinstall from previous

versions of firmware for a component that are stored in the Lifecycle

Controller. Instead of downloading the DUP, the

InstallFromSoftwareIdentity() creates a job and returns the job ID.
