It is recommended to keep the firmware updated to ensure you have the latest features and security updates. You may need
to rollback an update or install an earlier version if you encounter any issues after an update. To install an earlier version, use
Lifecycle Controller to check for updates and select the version you want to install.
For the details about supported and unsupported components for firmware rollback, refer to the table Firmware update
supported components on page 76
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 (not supported on MX platforms)
OME-Modular web interface (Supported on MX platforms)
CMC RACADM CLI (not supported on MX platforms)
iDRAC RACADM CLI
Lifecycle Controller GUI
Lifecycle Controller-Remote Services
Rollback firmware using iDRAC web interface
To roll back device firmware:
1. In the iDRAC Web interface, go to Maintenance > System Update > Rollback.
The Rollback page displays the devices for which you can rollback the firmware. You can view the device name, associated
devices, currently installed firmware version, and the available firmware rollback version.
2. Select one or more devices for which you want to rollback the firmware.
3. Based on the selected devices, click Install and Reboot or Install Next Reboot. If only iDRAC is selected, then click
Install.
When you click Install and Reboot or Install Next Reboot, the message Updating Job Queue is displayed.
4. Click Job Queue.
The Job Queue page is displayed, where you can view and manage the staged firmware updates.
NOTE:
While in rollback mode, the rollback process continues in the background even if you navigate away from this page.
An error message appears if:
You do not have Server Control privilege to rollback any firmware other than the iDRAC or Configure privilege to rollback
iDRAC firmware.
Firmware rollback is already in-progress in another session.
Updates are staged to run or already in running state.
If Lifecycle Controller is disabled or in recovery state and you try to perform a firmware rollback for any device other than
iDRAC, an appropriate warning message is displayed along with steps to enable Lifecycle Controller.
