Dell Update Packages Version 14.11.201 User's Guide

Logging occurs when you run a command for a DUP. The logs maintain information about all update activities. DUPs write to the Messages log. If you install the same package more than once on the same system, the log is appended. The messages files directory contain messages about a wide range of events on the system. Therefore, you must scan through the log file to find the messages that are relevant to DUPs.
