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:
v POST error messages and event logs
The power-on self-test (POST) generates messages to indicate successful test completion or the
detection of a problem. See "POST" on page 18, "Event logs" on page 19, and "POST error codes" on
page 21 for more information.
v System-event log
The system-event log contains all IMM, POST, and system management interrupt (SMI) events. See
"Event logs" on page 19 and "System event log" on page 28 for more information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See "Troubleshooting tables"
on page 49 for more information.
v Dynamic System Analysis (DSA) Preboot diagnostic programs
The DSA Preboot diagnostic programs provide problem isolation, configuration analysis, and event 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 configuration
– Network interfaces and settings
– Installed hardware
– Service processor status and configuration
– Vital product data, firmware, and UEFI configuration
– Hard disk drive health
– RAID controller configuration
– Controller event logs, including the following information:
- System event logs
- Temperature, voltage, and fan speed information
- Self-monitoring Analysis, and Reporting Technology (SMART) data
- Machine check registers
- USB information
- Monitor configuration information
- PCI slot information
The diagnostic programs create a merged log that includes events from all collected logs. The
information is collected into a file that you can send to Lenovo service and support. Additionally, you
can view the server information locally through a generated text report file. You can also copy the log
to removable media and view the log from a Web browser. See "Running the diagnostic programs" on
page 67 and "Diagnostic messages" on page 68 for more information.
v Server LEDs
Use the LEDs on the server to diagnose system errors quickly. See "Error LEDs" on page 62 for more
information.
