System messages
For a list of event and error messages generated by the system firmware and agents that monitor system
components, see the Dell Event and Error Messages Reference Guide at dell.com/idracmanuals.
Warning messages
A warning message alerts you to a possible issue and prompts you to respond before the system
continues a task. For example, before you format an HDD, a message warns you that you may lose all
data on the HDD. Warning messages usually interrupt the task and require you to respond by typing y (yes)
or n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more
information, see the documentation that accompanied the operating system or application.
