Roll Back to Earlier Firmware Version
Lifecycle Controller allows roll back to a previously-installed version of component firmware such as
BIOS, iDRAC, RAID Controller, NIC, and Power supply.
Important
 The Dell Diagnostics, OS driver packs, and Lifecycle Controller firmware cannot be rolled back
to previous versions. 
 The previous version is available only if the component firmware is updated at least once to a
different version. 
 The previous version of the firmware image is overwritten every time an update is performed. 
 Every time a rollback is performed, the previously installed firmware becomes the current
version, and the previous version will not be available. However, for iDRAC, 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. However, the previous version of PSU firmware is available
if Lifecycle Controller Firmware Update feature or Lifecycle Controller-Remote Services is used
to update the firmware. 
