Using Remote Update

Remote update, also known as out-of-band update or operating system-

independent platform update, allows you to update the system independent

of the state of the operating system. You can initiate the firmware update

regardless of the system power on or off state.

Benefits of Remote Update

With Operating System independent platform update, an operating system

need not be running on the system. Multiple updates can be scheduled

together along with a graceful or power-cycle reboot into UEFI system

services to perform the updates. Although the updates may involve

intermediate BIOS restarts, Lifecycle Controller will automatically handle

them until the updates are complete.

This feature supports two methods to perform updates:

•

Install from Uniform Resource Identifier (URI)

— This method allows a

WS-Management request to install or update software on a host platform

using a URI. The URI consists of a string of characters used to identify or

name a resource on the network. The URI is used to specify the location of

the Dell Update Package image on the network that can be downloaded to

the Lifecycle Controller and then installed.

•

Install from Software Identity

— This method allows update or rollback

to a version that is already available on the Lifecycle Controller.

You can use a WS-Management capable application, script or command line

utility to perform a remote update. The application or script performs WS-

Management invoke method request using one of the remote update

interface methods. The iDRAC then downloads the firmware from the

network share (local network share, CIFS, NFS, FTP, TFTP, http) URI and

stages the updates to be performed at the specified time and utilizing the

specified graceful, power cycle or none system reboot types.
