NOTE: On a 12th generation of PowerEdge server with firmware version 2.10.10.10, you cannot roll

back Lifecycle Controller to 1.xx.xx without rolling back iDRAC. You must roll back iDRAC first to

1.xx.xx version and only then can you roll back Lifecycle Controller.

You can perform firmware rollback for the following components:

• iDRAC with Lifecycle Controller

• BIOS

• Network Interface Card (NIC)

• Power Supply Unit (PSU)

• RAID Controller

• Backplane

NOTE: You cannot perform firmware rollback for Diagnostics, Driver Packs, and CPLD.

Before rolling back the firmware, make sure that:

• You have Configure privilege to roll back iDRAC firmware.

• You have Server Control privilege and have enabled Lifecycle Controller to roll back firmware for any

other device other than the iDRAC.

• Change the NIC mode to Dedicated if the mode is set as Shared LOM.

You can roll back the firmware to the previously installed version using any of the following methods:

• iDRAC web interface

• CMC web interface

• RACADM CLI (iDRAC and CMC)

• Lifecycle Controller GUI

• Lifecycle Controller-Remote Services
