Diagnostic Error Messages
Error messages are stored in volatile RAM and are lost when you remove
power from the switch. Access the error message log to view error messages
before powering down the switch.
Error messages are displayed through a Telnet session. The messages are
stored in the system log and display when you execute the
errShow
command.
NOTE:
If you run the portStatsShow command or the diagShow command before running
a test, errors can display as a result of the normal synchronization process. These errors
should be addressed if the number of errors found increases when running the
portStatsShow command again.
Where multiple probable cause and corrective actions follow an error message,
they are listed with the most probable cause and action first and the least
probable cause and action last.
If a port fails a diagnostic test, it is marked
BAD
in the status display and is
ignored until the system is rebooted. To retest a port that has been marked
BAD
,
clear the port and set it to
OK
using the
diagClearError (port #)
command. This
command clears the port status, but does not clear the error logs or change the
port’s condition. Only use the
diagClearError (port #)
command during diagnostic
procedures to reset a bad port for retesting.
For more detailed error message information, see Chapter 5,
“Error Messages.”
