crashdc(8)crashdc(8)NAMEcrashdc - 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, run‐
ning 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 sys‐
tem.
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.
