Lenovo 3823, 3821, 3822, 3719 manual Diagnostic tools, Event logs

Chapter 5. Diagnostics

This chapter describes the diagnostic tools that are available to help you solve problems that might occur in the server.

If you cannot diagnose and correct a problem by using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 275 for more information.

Diagnostic tools

The following tools are available to help you diagnose and solve hardware-related problems:

vPOST error messages

The power-on self-test (POST) generates messages to indicate successful test completion or the detection of a problem. See “POST error codes” on page 30 for more information.

vEvent logs

For information about the POST event log, the system-event log, the integrated management module (IMM) event log, and the DSA log, see “Event logs” and “System-event log” on page 38.

vTroubleshooting tables

These tables list problem symptoms and actions to correct the problems. See “Troubleshooting tables” on page 64.

vEasyLED diagnostics

Use the EasyLED diagnostics to diagnose system errors quickly. See “EasyLED

diagnostics” on page 76 for more information.

v Diagnostic programs, messages, and error codes

The diagnostic programs are the primary method of testing the major

components of the server. See “Diagnostic programs, messages, and error

codes” on page 90 for more information.

Event logs

Error codes and messages are displayed in the following types of event logs:

vPOST event log: This log contains the three most recent error codes and messages that were generated during POST. You can view the POST event log through the Setup utility.

vSystem-event log: This log contains all IMM, POST, and system management interrupt (SMI) events. You can view the system-event log through the Setup utility and through the Dynamic System Analysis (DSA) program (as the IPMI event log).

The system-event log is limited in size. When it is full, new entries will not overwrite existing entries; therefore, you must periodically save and then clear the system-event log through the Setup utility when the IMM logs an event that indicates that the log is more than 75% full. When you are troubleshooting, you might have to save and then clear the system-event log to make the most recent events available for analysis.

Messages are listed on the left side of the screen, and details about the selected message are displayed on the right side of the screen. To move from one entry to the next, use the Up Arrow (↑) and Down Arrow (↓) keys.
