Dell Command | Update Version 5.x User's Guide

Dell Command | Update supports the ability to install BIOS updates even if BitLocker Encryption is enabled on the system's boot drive. This feature suspends BitLocker while the BIOS is updated and resumes BitLocker encryption once the BIOS has been upgraded.

Dell Command | Update provides a check box in the BIOS settings screen to Automatically suspend BitLocker and displays the following warning message: Warning: Automatically suspending BitLocker drive encryption must be executed in a secure environment to safeguard the drive security.

If BitLocker is enabled, the following options are applied:

• When a BIOS update is available, select the Automatically suspend BitLocker option, and the Automatically restart the system (when required) option is selected. By default this option is disabled. When the BIOS update is installed, BitLocker is suspended temporarily to apply the BIOS updates. After the BIOS and other updates are installed, the system automatically reboots to complete the BIOS update, and BitLocker is reenabled.
• If a BIOS update is available within the list of the Selected Updates, a BitLocker icon is displayed.
• If you uncheck the Automatically suspend BitLocker option, the BIOS update is unchecked and disabled.
  NOTE:Hovering over the icon displays This update is blocked because BitLocker is enabled on this system. If you want to install this update, please check Automatically suspend BitLocker in the BIOS settings pane message.
• The Dell Command | Update command-line interface provides an equivalent command line option -autoSuspendBitLocker=<enable|disable> to automatically suspend the BitLocker. If the BitLocker option is enabled on the OS Boot drive, disabling the -autoSuspendBitLocker=<enable|disable> command line option blocks the installation of the BIOS updates. For more information, See the Dell Command | Update command line interface options.
