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 previouslyinstalled 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.
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.
