Using The Crash Log - HP StorageWorks SR2122 User Manual

Maintaining and Managing the Storage Router

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.txt
and 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.
The crash log provides the following information:
