NOTE: Lifecycle Controller allows 256 characters in a path that includes the file name and file extension. For example, if

56 characters are used for file name and extension, only 200 characters can be used for the path. Lifecycle Controller

does not support these characters -:, *,?,”,<,>,|,#,%,^, and SPACE.

Selecting and applying updates

1. To select and apply the updates, from the Available System Updates table, select the check box corresponding to the component

that has the firmware you want to update. After you select the catalog ID details, of the firmware selected are displayed in the

following format:

Release Date: YYYY-MM-DD

Source: USB Drive or CD or DVD (<

device type

>): \<

firmware file name in .exe format

By default, Lifecycle Controller selects the components for which the current updates are available.

2. Click Apply. The system may restart after the update process is complete. When applying more than one update, the system may

restart between the updates and launch back to Lifecycle Controller, and continue with the other selected updates.

NOTE: The system does not restart after updating the operating system driver pack and hardware diagnostics.

NOTE: While using Lifecycle Controller to update the power supply unit (PSU) firmware, the system turns off after the

first task. It takes a couple of minutes to update the PSU firmware, and then automatically turns on the server.

Firmware rollback

Lifecycle Controller allows you to roll back to a previously installed version of component firmware such as BIOS, iDRAC with Lifecycle

Controller, RAID Controller, NIC, Enclosure, Backplane, Fibre Channel cards, and Power Supply Unit (PSU). Use this feature if you have a

problem with the current version, and want to revert to the previously‑installed version.

On the Dell 13th generation 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 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.

Rolling back to previous firmware versions

You can roll back to earlier versions of a firmware using the Firmware Rollback wizard.

NOTE:

If you update any firmware only once, the rollback feature provides the option to revert to the factory-installed

component firmware image. If you update the firmware more than once, the factory‑installed images are overwritten

and you cannot revert to them.

To roll back a firmware:

1. Start Lifecycle Controller. For more information, see Starting Lifecycle Controller.

2. In the left pane, click Firmware Update.
