<br>
</span>Please take a look at calculation in<br>
<br>
<a href="http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing" target="_blank">http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing</a><br>
<br>
Host status will to Non Responding if either number of unsuccessful<br>
connection attempts exceeds VDSAttemptsToResetCount or timeout from<br>
last successful connection is expired.<br>
<br>
To alter time for host to be fence you can change these values from above<br>
mentioned calculation can be changed using engine-config tool:<br>
<br>
VDSAttemptsToResetCount<br>
TimeoutToResetVdsInSeconds<br>
DelayResetPerVmInSeconds<br>
DelayResetForSpmInSeconds<br>
<br>
<br>
Is there any specific issue for which you need to change those values?<br>
