Users Guide

• Except for iDRAC firmware, the earlier version of the firmware is not displayed if the current version

and the earlier version are the same.

• Every time a firmware image is updated, the earlier version of the firmware image is backed up.

• Every time a rollback operation is performed, the previously installed firmware becomes the current

version. However, for iDRAC, the previously installed version becomes the current version and the

current version is stored as the previous version.

• The earlier version of the firmware is available only if any of the following tools are used to update the

firmware: Lifecycle Controller Firmware Update feature, Lifecycle Controller-Remote Services, or the

Dell Update Package (DUP) from operating system.

NOTE: You cannot roll back to firmware version 1.x.x or earlier on a 13th generation PowerEdge

server.

Rolling back to previous firmware versions

You can roll back to earlier versions of a firmware using the Firmware Rollback wizard.

NOTE: If you update any firmware only once, the rollback feature provides the option to revert to

the factory-installed component firmware image. If you update the firmware more than once, the

factory‑installed images are overwritten and you cannot revert to them.

To roll back a firmware:

1. Start Lifecycle Controller. For more information, see Starting Lifecycle Controller.

2. In the left pane, click Firmware Update.

3. In the right pane, click Launch Firmware Rollback.

The Firmware Rollback page displays a list of components for which roll back is available and the

later versions are selected by default.

4. Select the required rollback image and click Apply.

After the update process is complete, the system may restart. When applying more than one update,

the system may restart between updates and launch back to Lifecycle Controller and continue

updating.
