Chapter 4. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve problems that might occur in
the server.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related problems:
POST error messages and error logs
The power-on self-test (POST) generates messages to indicate successful test completion or the
detection of a problem. See “POST” on page 19, “Event logs” on page 17, and “POST error codes” on
page 19
for more information.
Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See “Troubleshooting tables”
on page 46 for more information.
Dynamic System Analysis (DSA) Preboot diagnostic programs
The DSA Preboot diagnostic programs provide problem isolation, conguration analysis, and error log
collection. The diagnostic programs are the primary method of testing the major components of the server
and are stored in integrated USB memory. The diagnostic programs collect the following information
about the server:
System conguration
Network interfaces and settings
Installed hardware
Service processor status and conguration
Vital product data, rmware, and UEFI conguration
Hard disk drive health
RAID controller conguration
Controller and service processor event logs, including the following information:
System error logs
Temperature, voltage, and fan speed information
Self-monitoring Analysis, and Reporting Technology (SMART) data
Machine check registers
USB information
Monitor conguration information
PCI slot information
The diagnostic programs create a merged log that includes events from all collected logs. The information
is collected into a le that you can send to Lenovo service and support. Additionally, you can view the
server information locally through a generated text report le. You can also copy the log to removable
media and view the log from a Web browser. See “Running the diagnostic programs” on page 65
for
more information.
Server LEDs
Use the LEDs on the server to diagnose system errors quickly. See “System-board LEDs” on page 112
for more information.
