Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v Diagnostics DVD
The Diagnostics DVD provided with your server contains the diagnostic programs
for testing the major components of the server. For additional information about
the Diagnostics DVD, see the Hardware Maintenance Manual.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 144 for more information.
v EasyLED
Use EasyLED to diagnose system errors quickly. See “EasyLED diagnostics
panel” on page 17 for more information.
v Preboot diagnostic programs
The 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
– EasyLED status
– Service processor status and configuration
– Vital product data, firmware, and UEFI configuration
– Hard disk drive health
– RAID controller configuration
– Controller and service processor event logs, including:
- System error logs
- Temperature, voltage, and fan speed information
- Systems management analysis and reporting technology (SMART) data
- Machine check registers
- USB information
- Video and monitor configuration information
- Video memory test results
- 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.
