The following KB outlines how to upgrade the firmware of a DL Appliance using the Lifecycle Controller with the FTP Server selection.
NOTE: These steps can be carried out to upgrade the appliance firmware if there is a warning in the Appliance tab and Open Manage Server Administrator (OMSA) that there is firmware out of date.
NOTE: To update the firmware via Lifecycle Controller will require a reboot.
NOTE: When applying more than one update, the system may restart between updates. In this case, Lifecycle Controller restarts the server and automatically continues the update process.
