Warning Messages
A warning message alerts you to a possible problem and asks you to take corrective action before the system continues a task. For example, before you
format a diskette, a message might warn you that you might lose all data on the diskette, as a way to protect against inadvertently erasing or writing over
the data. These warning messages usually interrupt the procedure and require you to respond by typing y (yes) or n (no).
Diagnostics Messages
When you run a test group or subtest in the system diagnostics, an error message might result. These particular error messages are not covered in this
section. Record the message on a copy of the Diagnostics Checklist (located in "Getting Help" in the Installation and Troubleshooting Guide, and then follow the
instructions in that section for obtaining technical assistance.
Alert Log Messages From the System Management Server Agent
The optional system management software generates alert messages for your system. For example, the server agent generates messages that appear in the
SNMP trap log file. Alert messages consist of information, status, warning, and failure messages for drive, temperature, fan, and power conditions. More
information about alert messages is provided in the system management software documentation found on the Online Documentation CD that shipped with
your system.
