Diagnostic
Tests
If an error message is displayed next to a device name when you
issue one of the
show
commands described in Chapter 13, you
can test the device listed in the error message by using the
test
command.
Using this command, you can run a number of diagnostic tests to
help you determine the status of a system module or device.
