7.3 BIOS Firmware “Rollback”

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

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

All steps to complete a rollback successfully are listed below.

Invoke InstallFromSoftwareIdentity() with the following parameters and syntax:

[InstanceID]: This is the instanceID of the SoftwareIdentify that is to be used to rollback the firmware to a

previous version. The InstanceID can have value such as:

DCIM:AVAILABLE:NONPCI:159:2.1.4

 It is available firmware on a NONPCI device.

 This refers BIOS version 2.1.4

EXAMPLE:

winrm i InstallFromSoftwareIdentity cimv2/root/dcim/ DCIM_SoftwareInstallationService

?CreationClassName=DCIM_SoftwareInstallationService

+SystemCreationClassName=DCIM_ComputerSystem +SystemName=IDRAC:ID

+Name=SoftwareUpdate -file:RollInputBIOS.xml -u:[USER] -p:[PASSWORD]

-r:https://[IPADDRESS]/wsman:443 -auth:basic -encoding:utf-8
