Collecting and reporting failure 
information 

If an exception has occurred, first record the following failure information immediately and then report 
them to H3C Support: 

 

Symptom, time of failure, and configuration. 

 

Network topology information, including the network diagram, port connections, and points of 
failure. 

 

Log messages and diagnostic information. 

 

Steps you have taken and the result. 

Collecting basic failure information 

Table 13

 shows the basic failure information to be collected if the device is faulty. 

Table 13 Basic failure information 

Item 

Collection method 

Time of failure 

Record the time when the failure occurred down to the minute. 

Symptom 

Record detailed symptom of the failure. 

Impact 

Record the failure severity and affected services. 

Networking 

Draw a network diagram, including uplink and downlink devices and 
connected interfaces. 

Steps you have taken 

Record the steps you have taken and the results, including output from the

Collecting log information 

Log information records daily information, user actions, system failures, system safety, and system 
debugging. It includes diagnosis  monitoring  log messages,  diagnostic  log messages,  system  log 
messages, and debug log messages. 

To obtain the most recent log information, save the collected log messages to a log file. 

To collect log information: 

1. 

The system automatically saves diagnosis monitoring log messages to a log file. 

By default, diagnosis monitoring log files are saved in the 

drvmon

 folder under the root 

directory of the storage device. 

2. 

The system automatically saves maintenance information to a file. 

By default, maintenance information is saved in the 

info

 folder under the root directory of the 

storage device. 

3. 

Save diagnostic log messages from the log buffer to a log file. 

diagnostic-logfile save 

By default, diagnostic log files are saved in the 

diagfile

 folder under the root directory of the 

storage device. 

4. 

Save system log messages from the log buffer to a log file.
