Dell Command | Update Version 3.1.1 User's Guide

Dependency installation

Dell Command | Update uses update packages to determine the latest updates for a system. An update package contains feature enhancements or changes in BIOS, firmware, drivers, applications, and software. Usually, the update is self-sufficient and runs the preinstallation and applicable dependencies; however, the update may be dependent as described here:

• Intra-dependencies: These updates are the same type as BIOS updates, and must be installed or updated in a particular order which may require multiple scans and updates.

  For example, consider that your system has version A01 of BIOS installed. Version A05 is the latest available update, but it requires version A03 as a prerequisite. Dell Command | Update updates the system to version A03 before allowing an update to version A05.

  NOTE: It takes more than one update cycle for the system to be updated to one or more latest available versions, which are initiated by the user.

• Inter-dependencies: If a component update requires an update of another dependent component of a different update type, then the dependent component has to be updated before the selected component can be updated to the recommended version.

  For example, consider that your system needs a firmware update. To update system firmware, you must first update the system BIOS to a required minimum version. Dell Command | Update updates the system BIOS to the required version before updating the system firmware.

  NOTE: When the application initiates a system update, it takes more than one update cycle for the system to be updated to one or more latest available versions.

NOTE: If the update you want to install has a dependency, Dell Command | Update notifies you during the update process with an information alert.

NOTE: Non-dependent and inter-dependent updates are installed prior to intra-dependent updates.
