NAME

  crashdc - Diagnostic data collection for a running or	crashed	system

SYNOPSIS

  /usr/bin/crashdc [system-kernel] [core-image]

DESCRIPTION

  The crashdc utility examines the core	image of the operating system to
  extract critical diagnostic data. This utility is a shell script that
  invokes several tools	and commands that extract selected parameters of a
  running or a crashed system (for example, system configuration, running
  processes, and panic messages).

  The arguments	to the crashdc utility are the system kernel and the core
  image. The default values are	/vmunix	and /dev/mem, respectively. If you
  specify no arguments,	the crashdc utility examines the running system.

  The system usually invokes the crashdc utility during	system startup.	If
  the most recent core dump has	been saved by the savecore command, both the
  core image and the system kernel (respectively vmcore.n and vmunix.n,	where
  the variable n is the	crash number) are saved	in the crash directory (by
  default, /var/adm/crash). Also, the crashdc utility saves the	output as the
  file crash-data.n (where the variable	n is the crash number) in the crash
  directory. The crashdc utility is invoked only if crash-data.n output	in
  the crash directory does not exist or	is not from the	most recent crash.
