Rolling back device rmware

You can roll back the rmware for iDRAC or any device that Lifecycle Controller supports, even if the upgrade was previously performed

using another interface. For example, if the rmware was upgraded using the Lifecycle Controller GUI, you can roll back the rmware using

the iDRAC web interface. You can perform rmware rollback for multiple devices with one system reboot.

On Dell’s 13

generation PowerEdge servers that have a single iDRAC and Lifecycle Controller rmware, rolling back the iDRAC rmware

also rolls back the Lifecycle Controller rmware. However, on a 12

generation PowerEdge server with rmware version 2.xx.xx.xx, rolling

back iDRAC to a previous version such as 1.xx.xx does not roll back the Lifecycle Controller rmware 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 rmware version 2.10.10.10, you cannot roll back Lifecycle Controller to

without rolling back iDRAC. Roll back iDRAC rst to 1.

version and only then can you roll back Lifecycle Controller.

It is recommended to keep the rmware 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.

You can perform rmware 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 rmware rollback for Diagnostics, Driver Packs, and

CPLD.

Before rolling back the rmware, make sure that:

• You have Congure privilege to roll back iDRAC rmware.

• You have Server Control privilege and have enabled Lifecycle Controller to roll back rmware 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 rmware 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
