[pve-devel] Blacklisting HP hardware watchdog timer module ?

I finally found how to disable watchdog management from dell openmanage.

simply edit :

/opt/dell/srvadmin/etc/srvadmin-isvc/ini/dcwddy64.ini

and comment:

;[HWC Configuration]
;watchDogObj.settings=0
;watchDogObj.expiryTime=480


That's all.


I'll add a note in the wiki.


>>IMHO very dangerous - maybe better to use softdog instead?

In think iTCO_wdt is a good one also, for intel motherboard (integrated in all ich chipsets)


But ipmi can have some avantage with dell, like taking screenshot of kernel panic for example.

The assumption is that watchdog-mux is the only tool with access 
to the watchdog. I think the watchdog is quite useless if 
someone/something else can change or modify the watchdog timers. 
IMHO very dangerous - maybe better to use softdog instead?
