Rolling back server component firmware
You can install the firmware image of the previously installed firmware for selected components or devices across one or more
servers. The firmware image is available within the Lifecycle Controller for a rollback operation. The availability is subject to
the version compatibility logic of the Lifecycle Controller. It also assumes the previous update was facilitated by the Lifecycle
Controller.
NOTE: To use this feature, you must have an Enterprise License.
Rolling back server component firmware using the CMC web interface
To roll back the server component firmware version to an earlier version:
1. In the left pane, click Server Overview → Update.
2. On the Server Component Update page, click the appropriate type in the Choose Update Type section.
3. In the Rollback Version column, select the option for the component or device for which you want to roll back the
firmware.
4. Select one of the following options:
● Reboot Now — Restart the server immediately.
● On Next Reboot - Manually restart the server at a later time.
5. Click Rollback. The previously installed firmware version is reinstalled for the selected component or device.
Upgrading server component firmware
You can install the next version of the firmware image for selected components or devices across one or more servers. The
firmware image is available within the Lifecycle Controller for a rollback operation. To use this feature, you must have an
Enterprise License.
NOTE:
For iDRAC and Operating System Driver packs firmware update, make sure the Extended Storage feature is
enabled.
It is recommended to clear the job queue before initializing a server component firmware update. A list of all jobs on the servers
is available on the Lifecycle Controller Jobs page. This page enables deletion of single or multiple jobs or purging of all jobs on
the server.
BIOS updates are specific to the model of the server. Sometimes, even though a single Network Interface Controller (NIC)
device is selected for firmware update on a server, the update may get applied to all the NIC devices on the server. This
behavior is inherent in the Lifecycle Controller functionality and particularly the programming contained with the Dell Update
Package (DUP). Currently, Dell Update Packages (DUP) that are less than 85 MB in size are supported.
If the update file image size is greater, the job status indicates that the download has failed. If multiple server component
updates are attempted on a server, the combined size of all the firmware update files may also exceed 85 MB. In such a
case, one of the component updates fails as its update file is truncated. To update multiple components on a server, it is
recommended to update the Lifecycle Controller and 32-Bit Diagnostics components together first. These do not require a
server reboot and are relatively quick to complete. The other components can then be updated together.
All Lifecycle Controller updates are scheduled for immediate execution. However, the system services can delay this execution
sometimes. In such situations, the update fails as a result of the remote share that is hosted by the CMC being no longer
available.
Upgrading server component firmware from file using CMC web interface
To upgrade the server components firmware version to the next version using the Update from File method:
1. In the CMC Web interface, in the system tree, go to Server Overview and then click Update > Server Component
Update.
The Server Component Update page is displayed.
2. In the Choose Update Type section, select Update from File. For more information, see Choosing Server Component
Firmware Update Type
3. In the Component/Device Update Filter section, filter the component or device (optional). For more information see
