I know I've installed Nagios open source before, I though it's only for that kind of thing. I never though that Red hat ent 4 would be like client/server on the crash dump.

I need a little help here. I have been studying crash dump and per what I am reading, you can dedicate a slice to use as a dump device. Now when you dedicate this slice, do you have to :
1) create a mount point?
2) add entry in /etc/vfstab?
3) is this slice wu or wm?
4) should... (3 Replies)

crashdc(8) System Manager's Manual crashdc(8)
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 configura-
tion, 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.
