How to configure the IPMI watchdog
An hardware watchdog will reset the computer if the system watchdog daemon is unresponsive, e.g. because the OS has crashed.
After enabling IPMI on a Linux system you can use this recipe to activate the watchdog in the BMC:
enable_ipmi_watchdog() {
[ -e /dev/ipmi0 ] || return 1
# default timeout of 10 s raised to allow some recovery time
echo 'options ipmi_watchdog timeout=23' >> /etc/modprobe.d/watchdog
modprobe ipmi_watchdog
echo ipmi_watchdog >> /etc/modules
apt-get install watchdog
echo 'watchdog-device = /dev/watchdog' >> /etc/watchdog.conf
/etc/init.d/watchdog start
}
