Undocumented problems
If you have completed the diagnostic procedure and the problem remains, the
problem might not have been previously identified by Lenovo. After you have
verified that all code is at the latest level, all hardware and software configurations
are valid, and no light path diagnostics LEDs or log entries indicate a hardware
component failure, contact Lenovo or an approved warranty service provider for
assistance. To open an online service request, go to http://www.lenovo.com/support.
Be prepared to provide information about any error codes and collected data and
the problem determination procedures that you have used.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly.
v Preboot Dynamic System Analysis (DSA) diagnostic programs
The Preboot DSA 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
– Light path diagnostics status
– Service processor status and configuration
– Vital product data, firmware, and UEFI configuration
– Hard disk drive health
– RAID controller configuration
– ServeRAID controller and service processor event logs, including:
- System error logs
- Temperature, voltage, and fan speed information
- Tape drive presence and read/write test results
- Systems management analysis and reporting technology (SMART) data
- 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 the
Lenovo Support Center. 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 54 for more information.
