HP ProLiant server errors 97
System Power Supply Failure (Power Supply X)
Event Type: Power supply failure
Action: Replace the power supply.
Unrecoverable Host Bus Data Parity Error...
...Unrecoverable Host Bus Address Parity Error
Event Type: Host bus error
CAUTION: Only authorized technicians trained by HP should attempt to remove the system
board. If you believe the system board requires replacement, contact HP Technical Support ("HP
contact information" on page 393) before proceeding.
Action: Replace the board on which the processor is installed.
Uncorrectable Memory Error (Slot X, Memory Module Y)...
...Uncorrectable Memory Error (System Memory)
Uncorrectable Memory Error (Memory Module Unknown)
Event Type: Uncorrectable error
Action: Replace the memory module. If the problem persists, replace the memory board.
Status codes (Port 84/85)
During POST, before control is passed to the operating system, 8-bit codes are output in pairs to a set of 8
LEDs on the system board. The LEDs display the binary representation of the last successful output code pair.
Each status code pair is also sent to iLO debug ports. Utilizing the iLO network connection, a current, ordered
list of debug codes that have been output can be observed.
Each pair of debug status codes consists of an 8-bit major code and an 8-bit minor code. To determine a
general area in POST that a failure occurred, you must know both the major code and minor code. The 8-bit
status codes are represented as hexadecimal numbers.
Viewing status codes
There are three methods to view the last successful status code pair. The first method utilizes the POST LEDs
located on the system board. The second method involves accessing a list of all previously output status codes
through the iLO web user interface. Both of these methods can be utilized if the system hangs at any point
during the POST system boot process. The third method is only useful for cases where the system hangs early
in the boot process. Early in the boot process, the status code is displayed in the lower right of the screen.
Using the LEDs on the system board
IMPORTANT: LEDs are not available on server blades. Status codes can only be viewed using
the system monitor display during the early boot process or through iLO.
A set of status LEDs is used to view POST debug codes in a binary representation. Only one set of 8-bit LEDs
is available for display, which allows for only one code (major or minor) to be viewed at a time. Typically,
