Rolling Back to Previous Versions

Use the InstallFromSoftwareIdentity() method to reinstall from previous versions of firmware that is stored in the

Lifecycle Controller. Instead of downloading the DUP, the InstallFromSoftwareIdentity() creates a job and returns the job

ID.

NOTE: Lifecycle Controller, Diagnostics, and Driver Pack updates cannot be rolled back.

Using Remote Firmware Inventory

The remote firmware inventory feature retrieves an inventory of the currently installed firmware on various devices in

the managed system. It also retrieves the versions available for rollback (N and N-1 versions).

The remote firmware inventory feature allows you to run an inventory independent of the system state and the operating

system state. You can get a list of firmware for devices that are installed, and also the firmware that is available for

rollback and reinstallation.

NOTE: The iDRAC user credentials that are used for the WS-Management request authentication require login

privileges to request firmware and embedded software inventory. However, it is not restricted to administrators.

using the WS-Management Web services protocol.

NOTE: There may be DCIM_SoftwareIdentity instances for hardware that were previously installed and

then removed. Such instances are put plisted in the inventory as available if CSIOR is not performed.

To retrieve the firmware inventory using Windows WS-Management:
