Update and Rollback in Lifecycle Controller
Enabled Server
Dell Lifecycle Controller Enabled Server is an embedded configuration utility that enables systems and storage management
tasks from an embedded environment throughout the life cycle of a system.
Residing on an embedded flash memory card, Lifecycle Controller is similar to a BIOS utility in that it can be started during the
boot sequence and can function independently of an installed operating system.
Using Lifecycle Controller, you can quickly identify, download, and apply system updates without searching the Dell Support
website. You can also configure the system BIOS and system devices (such as NIC, RAID, and iDRAC), deploy an operating
system, and run diagnostics to validate the system and the attached hardware.
NOTE: For information on update and rollback for iDRAC, see Integrated Dell Remote Access Controller 8 (iDRAC8) Version
2.00.00.00 Users Guide available at dell.com/esmmanuals.
NOTE: Certain platforms or systems may not support the full set of features provided by Lifecycle Controller.
Topics:
• Update in Lifecycle Controller
• Rollback in Lifecycle Controller
Update in Lifecycle Controller
You can update the system BIOS, iDRAC firmware, power supply firmware, RAID firmware, and NIC firmware. Use the wizard to
display a list of available updates for the system Platform Update
You can define a location to search for available updates from the following options:
● The Dell File Transfer Protocol (FTP) system (ftp.dell.com). You can use a proxy system to access ftp.dell.com.
● A USB device. When accessing updates from a local USB device, the USB device must be plugged in before selecting
the Platform Update option in Lifecycle Controller. For more information on updating the platform, see the Dell Lifecycle
controller User Guide available at dell.com/support/manuals.
After you select the updates you want to apply, Lifecycle Controller downloads and applies the updates. If you decide to
update any device in Lifecycle Controller, the update package of the corresponding device is downloaded. After successfully
downloading, verifying, and extracting the DUPs, the corresponding devices are updated. If the update fails, error messages are
displayed.
NOTE:
You can also select the required component updates through the selective updates feature. Select multiple updates
separated by a comma (,)or semicolon (;). The selective update feature is supported for devices which does not support the
rollback option.
Rollback in Lifecycle Controller
You can update any component, for example BIOS, in both Lifecycle Controller and the operating system environment. After
the update is successful in the operating system environment using DUPs, you can enter Lifecycle Controller and revert the
component to the version that was previously installed before the update occurred.
Lifecycle Controller supports platform firmware rollback to the previous version. If the operating system has a non–functioning
application because of a BIOS or firmware flash, reboot to Lifecycle Controller and roll back to the previous version.
NOTE:
The BIOS and firmware can be only rolled back. The Lifecycle Controller application, the Dell Diagnostics application,
and drivers required for operating system installation cannot be rolled back to an earlier version.
