Recovering from failures

Collecting information

Collecting information 

Providing the Response Center with a complete and accurate symptom 
description is important in solving any problem. The V-Class server’s 
SSP automatically records information on environmental and system 
level events in several log files. See “SSP file system” on page 54 for more 
information about these files. 

Use the following procedure to collect troubleshooting information:

Step 1. If an error message is displayed on the system console, record it.

Step 2. Record the information displayed on the system LCD. See “LCD (Liquid 

Crystal Display)” on page 28 for more information.

Step 3. Record any relevant information contained in the log files in 

the /spp/data/complex directory on the SSP: 

•

event_log

Main log file

•

hard_hist

Filtered output from the 

hard_logger

, appended after each error

Step 4. Record any relevant information contained in the syslog.log file in 

the /var/adm/syslog directory on the system disk. Access to this log file 
may require rebooting the system if it has hung or crashed.
