Dell Update Packages Version 14.11.201 User's Guide

DUPs are designed to confirm that all prerequisites are satisfied before applying the update to the system. Each DUP checks to ensure the following:

• The logged-on user has root privileges.
• DUP to be applied in the command is compatible with the target system and the operating system running on a system.
• The device associated with the DUP is present on the system.
• The minimum required versions of related system software are running on the system.

DUPs are designed with built-in error handling capabilities to ensure that the preceding requirements are validated. If the conditions are not met, no update occurs. DUPs also check for dependencies between BIOS and certain ESM packages. The application design allows you to create groups of DUPs and apply them to a wide range of systems. Additionally, if you only want to verify that a given package can be applied to the system, you can invoke the package by using the following CLI command:

./Packagename.bin ‑c for Linux

packagename.exe /c /s for Windows

This command executes the dependency rules within the DUP, issues any warnings, exits without applying the update to the system, and writes the results to the console. You can also use the DUP to set an exit code to perform decisions within the scripts.
