Chapter 3. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the server.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, “Getting help and technical assistance,” on page 293 for more
information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v 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 26, “Event logs”
on page 24, and “POST error codes” on page 26 for more information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 82 for more information.
v Dynamic System Analysis (DSA) Preboot diagnostic programs
The DSA Preboot diagnostic programs provide problem isolation, configuration
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 configuration
– Network interfaces and settings
– Installed hardware
– Vital product data, firmware, and UEFI configuration
– Integrated management module II (IMM2) status and configuration
– Hard disk drive health
– RAID adapter configuration
– Controller and IMM2 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 configuration information
- PCI slot information
The diagnostic programs create a merged log that includes events from all
collected logs. The information is collected into an XML file that you can send to
IBM service and support. Additionally, you can view the server information locally
through a generated text report file. You can also copy the outputs (xml.gz,txt,
html) to removable media and view the html from a web browser. See “Running
the diagnostic programs” on page 94 and “Diagnostic messages” on page 95 for
more information.
v Server LEDs
Use the LEDs on the server to diagnose system errors quickly. See “Server
controls, LEDs, and power” on page 11 for more information.
