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.
