uses existing system tools and utilities to extract information from crash
dumps. The information garnered from crash dump files or from the running
kernel includes the hardware and software configuration, current processes,
the panic string (if any), and swap information.
The crashdc utility is invoked each time the system is booted. If it finds a
current crash dump, crashdc creates a data collection file with the same
numerical file name extension as the crash dump (see Section 2.1.1 for
information about crash dump names).
You can also invoke crashdc manually. The syntax for compressed and
uncompressed crash dump files, respectively, is as follows:
/bin/crashdc vmunix.n vmzcore. n
/bin/crashdc vmunix.n vmcore. n
See Appendix A for an example of the output from the crashdc command.
