Compatibility Concerns
Meeting System Prerequisites
DUPs are designed to confirm that all prerequisites are satisfied before applying
the update to your system. Each DUP checks to ensure the following:
• The DUP applies to your target system.
• The DUP applies to the operating system running on your system.
• The device associated with the DUP is present on your system.
• Minimum required versions of related system software are running on
your 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. The design also allows you to create groups of DUPs and apply
them to a wide range of systems. For example, if some of the Dell systems in
your environment contain PERC 6/i RAID controllers and the others contain
PERC 5/i controllers, you could include both the PERC 6/i and PERC 5/i
storage controller DUPs in one script and run this script on every system in
your environment. The RAID Update Packages would be installed on the
systems as appropriate, while the RAID Update Packages that did not apply
would not be installed.
Additionally, if you only want to verify that a given DUP can be applied to your
system, you can invoke the package by using the following CLI command:
packagename .exe /c /s
