6 FAQs about [Bmc ipmi watchdog timer timeout action system power reset hp]

What is a BMC watchdog timer?

The BMC watchdog timer in Dell PowerEdge Systems is a feature defined in the Intelligent Platform Management Interface (IPMI) v2.0 specification. It can restart, turn off, or cycle power to your server in your absence to support automatic system recovery functions.

Does ipmitool reset watchdog timer?

According to ipmitool manual, it will reset the IPMI Management Controller watchdog timer. As I understand, this command resets the watchdog timer back to 300s. Once the timer reaches 0, the system is rebooted. However, is there a some sort of watchdog automatically set to place during the installation of ipmitool?

Does 0x00 trigger a watchdog timer?

EDIT. Also when I trigger watchdog timer with echoing \0x00 to /dev/watchdog and then kept it untouched -- system is correctly rebooted after default 10 second timeout. So watchdog works good but at exactly 350 seconds from startup system reboots.

How often does a watchdog timer reset a computer?

the watchdog timer would reboot the hardware every 300 seconds, but at the same time a software timer resets the hardware watchdog timer every 5 seconds. So it is constantly being reset back to 300 seconds. It is done for the purpose where if your machine gets hung the hardware timer will countdown to 0 and cause a reboot within 300 seconds.

Does ipmitool see watchdog hardware?

Programs apparently see watchdog hardware (ipmitool with openipmi enabled): Freeipmi: However, after certain amount of time I get (with good "current countdown" values reported by programs above): [ 294.107534] Uhhuh. NMI received for unknown reason 21 on CPU 0. [ 294.107998] Do you have a strange power saving mode enabled?

Can interrupt storm cause a watchdog to reset?

If you have an interrupt storm, it can also cause the watchdog to reset, even if the computer does not really "hang". And querying it repeatedly shows the countdown doing what we'd expect, albeit with slightly wonky numbers. But the result seems to work.
