[Linux-cluster] Problem with rhel6 + rgmanager + ip service

I'm trying to setup a trivially simple cluster using RHEL 6.1
(cman+rgmanager). I've got three interfaces, and I want a managed IP on
192.168.2.100/24 (which should match eth1). At this point though, I'd be
happy to get any IP working on any interface.

Here's my config:

<?xml version="1.0"?>
<cluster config_version="15" name="an-clusterA">
	<cman expected_votes="1" two_node="1"/>
	<totem rrp_mode="none" secauth="off"/>
	<clusternodes>
		<clusternode name="an-node01.alteeve.com" nodeid="1">
			<fence>
				<method name="apc_pdu">
					<device action="reboot" name="pdu2" port="1"/>
				</method>
			</fence>
		</clusternode>
		<clusternode name="an-node02.alteeve.com" nodeid="2">
			<fence>
				<method name="apc_pdu">
					<device action="reboot" name="pdu2" port="2"/>
				</method>
			</fence>
		</clusternode>
	</clusternodes>
	<fencedevices>
		<fencedevice agent="fence_apc" ipaddr="192.168.1.6" login="apc"
name="pdu2" passwd="secret"/>
	</fencedevices>
	<fence_daemon post_join_delay="30"/>
	<rm>
		<resources>
			<ip address="192.168.4.100" monitor_link="on"/>
		</resources>
		<failoverdomains>
			<failoverdomain name="an1_primary" nofailback="1" ordered="1"
restricted="0">
				<failoverdomainnode name="an-node01.alteeve.com" priority="1"/>
				<failoverdomainnode name="an-node02.alteeve.com" priority="2"/>
			</failoverdomain>
		</failoverdomains>
		<service autostart="0" domain="an1_primary" name="san_ip"
recovery="relocate">
			<script ref="192.168.2.100"/>
		</service>
	</rm>
</cluster>

Running clustat says the IP should be up:

Cluster Status for an-clusterA @ Tue Aug  2 01:32:41 2011

 an-node02.alteeve.com                       2 Online, rgmanager

 service:san_ip                 an-node01.alteeve.com          started



I can't ping that IP from either node, nor does the IP appear in either
node's 'ipconfig -a'.

Any idea what I might be doing wrong?
