[Linux-cluster] start cluster with only one node present?

Hi folks,

i'm testing a two node cluster (on redhat 5.4, hp dl380g3). I'm using
fence_ilo,  have a quorum disk (*cluster.conf) and have an IP resource
and GFS2 mount point.

Every think works well, until I completely disconnect the power from
one node (ex. node1).

Now node2 can't fence node1 (since there is no connection to the fence
ilo device) and I can't start the cluster at all. When I try to reboot
node2 it hangs on Starting fencing...

I guess my question is: Is there a way to start the cluster if only
one node is present?

Thank you for any input.
