Error messages
Error messages indicate that a problem exists.
Hardware error messages that occur can be text, numeric,
or both. Messages generated by your software generally
are text messages, but they also can be numeric.
POST error messages:
POST error messages
occur during startup when POST finds a problem with the
hardware or detects a change in the hardware
configuration. For more information, see
“Symptom-to-FRU index” on page 194.
Diagnostic error messages:
Diagnostic error
messages occur when a test finds a problem with the
server hardware. These error messages are alphanumeric
and they are saved in the Test Log. For more information,
see “Error symptoms” on page 208.
Software-generated error messages:
These
messages occur if a problem or conflict is found by an
application program, the operating system, or both.
Messages are generally text messages, but they also can
be numeric. For information about these error messages,
refer to the documentation that comes with your software.
System error log
The system error log contains all error and warning
messages issued during POST and all system status
messages from the Netfinity Advanced System
Management Processor. See “System Event/Error Log” on
page 36 for information about how to view the system
error log.
Option diskettes
An optional device or adapter might come with an Option
Diskette. Option Diskettes usually contain option-specific
diagnostic test programs or configuration files.
If your optional device or adapter comes with an Option
Diskette, follow the instructions that come with the option.
Different instructions apply depending on whether the
Option Diskette is startable or not.
Recovering BIOS
If your BIOS has become corrupted, such as from a power
failure during a flash update, you can recover your BIOS
using the recovery boot block and a BIOS flash diskette.
