NAME¶

ipmi_watchdog - IPMI watchdog

DESCRIPTION¶

The kernel module ipmi_watchdog is used on systems that provide hardware watchdog functionality through an IPMI board. F.e. the Lenovo Integrated Management Module is such a board. In difference to other watchdog modules, the ipmi_watchdog needs a running daemon.

* prepare IPMI watchdog, 1st try

# chkconfig ipmi on

# vi /etc/sysconfig/bootloader
INITRD_MODULES="... ipmi_watchdog"

# vi /etc/modprobe.d/ipmi_watchdog
options ipmi_watchdog nowayout=0 timeout=30 action=reset_power
blacklist iTCO_wdt
blacklist iTCO_vendor_support

# shutdown -r now

* prepare IPMI watchdog, 2nd try

# chkconfig ipmi on

# vi /etc/sysconfig/ipmi
IPMI_WATCHDOG=yes
IPMI_WATCHDOG_OPTIONS="nowayout=0 action=reset_power timeout=30"

* show

# modinfo ipmi_watchdog

# ls -l /dev/watchdog
