IPMI watchdog not working


Oct 27, 2011
Hey guys, long time no see, but I'm back with a fresh problem.

There's a new HA cluster I'm setting up and I am having issues with the IPMI watchdog on one of the three servers. The kern.log once every second says:

Apr 4 17:42:14 prox5 kernel: [ 5105.588943] IPMI Watchdog: response: Error d5 on cmd 22

From strace I got:

epoll_wait(5, {}, 10, 1000) = 0
ioctl(3, WDIOC_KEEPALIVE, 0) = -1 EINVAL (Invalid argument)
write(2, "watchdog update failed: Invalid "..., 41watchdog update failed:
Invalid argument
) = 41

These are all HP blades, this one being a slightly different version (can only get details about that tomorrow).

lsmod does not show hpwdt by the way even though I havent blacklisted it:

root@prox5:~# lsmod|grep hp
hpilo 20480 0
shpchp 36864 0
hpsa 98304 1
scsi_transport_sas 45056 1 hpsa

Turns out the error spam stops if I stop the watchdog-mux service but that also stops the ipmi watchdog from setting and resetting timers. Since watchdog-mux has no documentation I could find anywhere... how do I find out which watchdog other than ipmi it is trying to use thats not actually there? And how do I make it stop that...

Any hints are greatly appreciated.

So... turns out theyre all HP BL460C Gen8s. CPUs are different tho. Problematic prox5 has: Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz
Other 2 have: Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz

things just got weirder still. This error spam from the IPMI watchdog *stops* if you ENable HP ASR (their own watchdog thingie) and then reboot:

hpasmcli -s "enable asr";reboot
The wiki says to DISable all other watchdogs that may be active but here you have to ENable the HP watchdog so that ipmi_watchdog then uses it instead of the actual IPMI systems? Im confused.
