In Cluadmin you can perform failover testing by right clicking on the
resource. Keep in mind that if you initiate a failure using this method how
many times the resource has to fail before it actualy moves to the other
group. Defaults is usually around 3 times, with the resource moving to the
other node on the 4th failure.

I prefer physically unplugging the NIC whenever possible so that I see the
actual response of the cluster. Found a hole in our design once when we had
a group that didn't have an IP Address or network name resources, so when
the NIC was unplugged everything failed over to the other node with the
exception of the group lacking the above resources.

Right clicking and using the Initiate failure option gives me a warm fuzzy,
but physically pulling the cable lets me sleep at night.
