Gathering Troubleshooting Information
If you experience problems with the storage router, you may need to obtain troubleshooting information
for Cisco technical support personnel. The SN 5428-2 Storage Router provides several features that can
help you assemble the necessary information.
The following are typical activities involved with troubleshooting the SN 5428-2:
• Using the Crash Log, page 11-33
• Using FTP with the SN 5428-2 Storage Router, page 11-35
• Understanding Diagnostics, page 11-36
• Capturing System Messages at Bootup, page 11-36
• Capturing the Storage Router Configuration, page 11-37
• Using Debug Facilities, page 11-37
Using the Crash Log
If the storage router experiences an unexpected problem that forces it to automatically reboot, a special
log file is generated. The file is named crash-cpp.txt and it is stored in the log directory (/ata4/log). You
can display the contents of this file to the console using the show crash command.
To save the show crash command output, redirect the output of your console using the logging facilities
for your specific console interface. Depending on your console interface and scroll buffer size, you may
also be able to copy and paste the contents from your console into an ASCII text file.
