Good morning!
On a CentOS 6.4 / 64 bit server I have
installed the watchdog 5.5 package.
The rpm -qi watchdog states:
The watchdog program can be used as a powerful software watchdog
daemon or may be alternately used with a hardware watchdog device such
as the IPMI hardware watchdog driver interface to a resident Baseboard
Management Controller (BMC).
...
This configuration file is also used to set the watchdog to be used as
a hardware watchdog instead of its default software watchdog
operation.
In the dmesg output of my server
( full text at http://pastebin.com/GbF7dRt7 )
I see such a device:
NMI watchdog enabled, takes one hw-pmu counter.
...
ipmi message handler version 39.2
IPMI System Interface driver.

iTCO_wdt: Found a Lynx Point TCO device (Version=2, TCOBASE=0x1860)
iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0)
My question is: what should I put into
/etc/watchdog.conf to enable the
hardware watchdog instead of the
default software watchdog mode?
I've also asked this question at

Thank you
