15. Turn off the blade server, remove it from the BladeCenter unit, and remove the cover of the blade server. 16. Move the J16 jumper to pins 1 and 2 to return to normal startup mode. 17. Replace the cover and reinstall the blade server in the BladeCenter unit; then restart the blade server. The system starts up. Statement 21: CAUTION: Hazardous energy is present when the blade server is connected to the power source. Always replace the blade cover before installing the blade server. Service processor (BMC) error codes The baseboard management controller (BMC) log contains up to 512 of the most recent service processor errors in IPMI format. These messages are a combination of plain text and error code numbers. You can view the BMC log from the Configuration/Setup Utility menu by selecting Advanced Setup > Baseboard Management Controller (BMC) Settings > BMC System Event Log. You can view additional information and error codes in plain text by viewing the management-module event log in your BladeCenter unit. Solving SCSI problems For any SCSI error message, one or more of the following devices might be causing the problem: v A failing SCSI device (adapter, drive, or controller) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain For any SCSI error message, make sure that the SCSI devices are configured correctly. Solving undetermined problems Note: When you are diagnosing a problem in the LS20 Type 8850, you must determine whether the problem is in the blade server or in the BladeCenter unit. v If all of the blade servers have the same symptom, it is probably a BladeCenter unit problem; for more information, see the Hardware Maintenance Manual and Troubleshooting Guide or Problem Determination and Service Guide for your BladeCenter unit type. v If the BladeCenter unit contains more than one blade server and only one of the blade servers has the problem, troubleshoot the blade server that has the problem. If the diagnostic tests did not diagnose the failure or if the blade server is inoperative, use the information in this section. 50 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

15.
Turn off the blade server, remove it from the BladeCenter unit, and remove the
cover of the blade server.
16.
Move the J16 jumper to pins 1 and 2 to return to normal startup mode.
17.
Replace the cover and reinstall the blade server in the BladeCenter unit; then
restart the blade server. The system starts up.
Statement 21:
CAUTION:
Hazardous energy is present when the blade server is connected to the power
source. Always replace the blade cover before installing the blade server.
Service processor (BMC) error codes
The baseboard management controller (BMC) log contains up to 512 of the most
recent service processor errors in IPMI format. These messages are a combination
of plain text and error code numbers. You can view the BMC log from the
Configuration/Setup Utility menu by selecting
Advanced Setup > Baseboard
Management Controller (BMC) Settings > BMC System Event Log
.
You can view additional information and error codes in plain text by viewing the
management-module event log in your BladeCenter unit.
Solving SCSI problems
For any SCSI error message, one or more of the following devices might be
causing the problem:
v
A failing SCSI device (adapter, drive, or controller)
v
An improper SCSI configuration
v
Duplicate SCSI IDs in the same SCSI chain
For any SCSI error message, make sure that the SCSI devices are configured
correctly.
Solving undetermined problems
Note:
When you are diagnosing a problem in the LS20 Type 8850, you must
determine whether the problem is in the blade server or in the BladeCenter unit.
v
If all of the blade servers have the same symptom, it is probably a BladeCenter
unit problem; for more information, see the
Hardware Maintenance Manual and
Troubleshooting Guide
or
Problem Determination and Service Guide
for your
BladeCenter unit type.
v
If the BladeCenter unit contains more than one blade server and only one of the
blade servers has the problem, troubleshoot the blade server that has the
problem.
If the diagnostic tests did not diagnose the failure or if the blade server is
inoperative, use the information in this section.
