Diagnostic tools overview
POST error messages and beep codes
POST error messages and beep codes occur during startup when
POST finds a problem with the hardware or detects a change in the
hardware configuration. POST error messages are 3-, 4-, 5-, 8-, or
12-character alphanumeric messages and include brief explanations
(except I999xxxx errors).
For more information about what caused an error message to
appear and what action to take, see “Power-on self-test (POST)
messages” on page 165 and “POST message table” on page 169.
Also see “Power-on self-test (POST) beep codes” on page 192.
SCSI error messages
These messages appear if a problem or conflict is detected by the
SCSI subsystem. Refer to the SCSI documentation in the
ServerGuide package that comes with your server for information
about these messages.
Diagnostic error messages
Diagnostic error messages occur when a test finds a problem with
the server hardware. The messages present text information that
can be used to identify a failing part. These error messages are
alphanumeric. Follow the instructions on the screen.
Software-generated error messages
These messages occur if a problem or conflict is found by an
application program, the operating system, or both. Error messages
for operating-system and other software problems are generally text
messages, but they also can be numeric messages. For information
about these software error messages, refer to the information that
comes with the operating system or application program, or both.
Troubleshooting charts
The charts under “Troubleshooting charts” on page 200 list
symptoms of problems (for example, a symptom might be “The
mouse is not working.”), along with steps to correct the problems.
