Error Messages

Overview
The system reports two kinds of self-test errors.

Errors that display on the console immediately after running
the self test
These error messages consist of one or two question marks to
indicate a nonfatal or fatal error, the failing FRU, the device
that failed, and a general error code.

Extended test errors
These error messages display more detailed information. To
view an extended error message, enter the SHOW ERROR
command at the console prompt, after the test has reported
an error.

The following example shows the format for immediate error
messages:
