Dell Lifecycle Controller Graphical User Interface Version 2.05.05.05 For 13th Generation Dell PowerEdge Servers User's Guide
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.
- NOTE: On the 13th generation of PowerEdge servers that have a single iDRAC and Lifecycle Controller firmware, rolling back iDRAC firmware will also rollback Lifecycle Controller.
- 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.
