Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v
POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem (see “POST error logs”
on page 90).
The POST error log contains the three most recent error codes and messages
that the system has generated during POST.
The system-error log contains all the error messages that were issued during
POST.
Note: The system-error log is available only with the Remote Supervisor Adapter
II SlimLine.
v
Diagnostic programs and error messages
The server diagnostic programs, stored in upgradable read-only memory (ROM)
on the system board, are the primary method of testing the major components of
the server (see “Diagnostic programs, error codes and messages” on page 91).
v
ServerGuide error symptoms
ServerGuide error symptoms are described at “ServerGuide error symptoms” on
page 131.
v
SCSI error messages
For information on SCSI errors, see “Small computer system interface messages”
on page 97 and “SCSI error codes” on page 132
v
Light path diagnostics
The server has light-emitting diodes (LEDs) to help you identify problems with
server components. By following the light path, you can identify the type of
problem that occurred. The light path begins with the LEDs on the operator
information panel (see “Light path diagnostics” on page 93).
v Error symptom tables
These tables list problem symptoms, along with suggested steps to correct the
problems (see the “Error symptoms” on page 122).
