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. ipmi_si: Adding default-specified kcs state machine ipmi_si: Trying default-specified kcs state machine at i/o address 0xca2, slave address 0x0, irq 0 ipmi_si: Interface detection failed ipmi_si: Adding default-specified smic state machine ipmi_si: Trying default-specified smic state machine at i/o address 0xca9, slave address 0x0, irq 0 ipmi_si: Interface detection failed ipmi_si: Adding default-specified bt state machine ipmi_si: Trying default-specified bt state machine at i/o address 0xe4, slave address 0x0, irq 0 ipmi_si: Interface detection failed ipmi_si: Unable to find any System Interface(s) ... iTCO_vendor_support: vendor-support=0 iTCO_wdt: Intel TCO WatchDog Timer Driver v1.07rh 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 http://serverfault.com/questions/539816/how-to-use-watchdog-daemon-with-hard...
Thank you Alex
Hi Alex,
Look to see if you have a /dev/watchdog device. If you do basically all you need to do is then service watchdog start. To test if it is working get the pid of the watchdog process and do a kill -9. If your box reboots then the hardware watchdog works.
There are some additional features you can have the watchdog program check, see the man page.
Hope this helps, Steve
