Rolling back device firmware

You can roll back the firmware for iDRAC or any device that is supported by Lifecycle Controller even if

the upgrade was previously performed using another interface. For example, if the firmware was

upgraded using the Lifecycle Controller GUI, you can roll back the firmware using the iDRAC web

interface. You can perform firmware rollback for multiple devices with one system reboot.

On Dell’s 13th generation of PowerEdge servers that have a single iDRAC and Lifecycle Controller

firmware, rolling back the iDRAC firmware also rolls back the Lifecycle Controller firmware. However, on

a 12th generation of PowerEdge server with firmware version 2.xx.xx.xx, rolling back iDRAC to a previous

version such as 1.xx.xx does not roll back the Lifecycle Controller firmware version. It is recommended

that you roll back Lifecycle Controller to a previous version after rolling back iDRAC.

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.

NOTE: Firmware version 1.xx.xx is not supported on a 13th generation PowerEdge system.

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

• Lifecycle Controller-Remote Services
