Anyway, in a nutshell you need to enable dumps in /etc/rc.conf by setting dumpdev to point at your swap device (I have dumpdev="/dev/sd0b"). Make sure that the swap partition pointed to is big enough to hold all your memory ! Then /etc/rc will automatically enable dumps by invoking dumpon. At least, that the way it works in FreeBSD-current. See the dumpon manpage for additioanl usefull information. If your system panics then the kernel should automatically write a crashdump to the swap device. All bets are off if you have ddb enabled. In that case the kernel will land in ddb if a panic happens. This doesn't work too well if you're in X Windows when a panic occurs since you'll never be able to switch to the vt where ddb is waiting for input. Unless you boot using a serial console I recommend against using ddb. --- Gary Jennejohn Home - garyj@muc.de Work - garyj@fkr.dec.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
