Roll Back to Previous 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 Platform Update feature, Lifecycle
Controller-Remote Services, or the Dell Update Package. However, the previous version
of PSU firmware is available if Lifecycle Controller Platform Update feature or
Lifecycle Controller-Remote Services is used to update the firmware.
