a 12th generation PowerEdge servers with firmware version 2.xx.xx.xx, if you want to roll back Lifecycle Controller firmware to a previous version such as 1.x.x, you must first roll back iDRAC to the previous version and then roll back Lifecycle Controller. It is not possible to roll back Lifecycle Controller to a previous version if iDRAC firmware version is 2.xx.xx.xx. • Dell Diagnostics, operating system driver packs, CPLD, and operating system collector tool cannot be rolled back to earlier versions. • The earlier version is available only if the component firmware is updated at least once to a different version. • 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.

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.
