Chapter 2. Diagnostics
This section describes the diagnostic tools that are available to help you solve
problems that might occur in the system-board tray and chassis.
To update the firmware, you might have to use an external USB CD-RW/DVD drive.
To run the BIOS configuration utility or the Dynamic System Analysis (DSA) Preboot
diagnostic programs, you must have the following additional hardware:
v
Monitor
v
Combination USB keyboard and pointing device such as IBM part number
40K5372
v
External USB CD-RW/DVD drive such as the IBM and Lenovo part number
73P4515 or 73P4516
If you cannot diagnose and correct a problem by using the information in this
section, see Appendix A, “Getting help and technical assistance,” on page 165 for
more information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v
POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
the detection of a problem. See “POST” on page 12 for more information.
v
Checkout procedures
Checkout procedures are available to help you diagnose server problems. The
basic checkout procedure is designed for anyone to use. The advanced checkout
procedure is intended for trained service technicians only. See “Checkout
procedures” on page 19 for more information.
v
Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 23 for more information.
v
Dynamic System Analysis (DSA) Preboot diagnostic programs
The DSA Preboot diagnostic programs collect and analyze system information to
aid in diagnosing problems. The diagnostic programs collect the following
information:
– System
configuration
– Network interfaces and settings
– Installed
hardware
– Service processor status and configuration
– Vital product data, firmware, and BIOS configuration
– Hard disk drive health
– RAID controller configuration
– Event logs for RAID controllers and the BMC
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 IBM
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.
