HA Config work with ip on fencedevice but don't work wirh hostname

[Syrck]

Hi,

I have two nodes working in HA in proxmox 3.3. The HA work correctly if i use ip on fencedevice:

<fencedevice agent="fence_ilo" ip="192.168.1.10" login="login" name="fenceNodeA" passwd="password"/>
<fencedevice agent="fence_ilo" ip="192.168.1.11" login="login" name="fenceNodeB" passwd="password"/>

But if i try to use hostname in fencedevice :

<fencedevice agent="fence_ilo" hostname="proxmox1" login="login" name="fenceNodeA" passwd="password"/>
<fencedevice agent="fence_ilo" hostname="proxmox2" login="login" name="fenceNodeB" passwd="password"/>

When i click to Activate for the new config, the system give me an error :

"config validation failed: unknown error (500)"

The hostnames are corrects. This is my cluster.conf.new :

<?xml version="1.0"?>
<cluster config_version="21" name="cluster">
<cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/>
<fencedevices>
<fencedevice agent="fence_ilo" hostname="proxmox1" login="login" name="fenceNodeA" passwd="passwd"/>
<fencedevice agent="fence_ilo" hostname="proxmox2" login="login" name="fenceNodeB" passwd="passwd"/>
</fencedevices>
<clusternodes>
<clusternode name="proxmox1" nodeid="1" votes="1">
<fence>
<method name="1">
<device action="reboot" name="fenceNodeA"/>
</method>
</fence>
</clusternode>
<clusternode name="proxmox2" nodeid="2" votes="1">
<fence>
<method name="1">
<device action="reboot" name="fenceNodeB"/>
</method>
</fence>
</clusternode>
</clusternodes>
<rm>
<pvevm autostart="1" vmid="102"/>
</rm>
</cluster>

Maybe is because the clusternode name and host are the same name ?

Thanks in advance,

Kim
