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/openmanagemanuals > OpenManage software.
Warning messages
A warning message alerts you to a possible problem and prompts you to respond before the system continues a task. For
example, before you format a hard drive, a message warns you that you may lose all data on the hard drive. 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.
Diagnostic messages
The system diagnostic utilities may issue messages if you run diagnostic tests on your system. For more information about
system diagnostics, see
Using system diagnostics
Alert messages
The systems management software generates alert messages for your system. Alert messages include information,
status, warning, and failure messages for drive, temperature, fan, and power conditions. For more information, see
the systems management software documentation (Dell OpenManage Systems Management Overview Guide at dell.com/
openmanagemanuals).
