Limitation of fencing attempts

[GigaZ]

Hello everyone,
I build a Proxmox 3.4 two node cluster with two Dell R210 and a third node as iscsiTarget. This works still great.
I use IDRAC for fencing and DRBD as storage. But after a powerfailure of node1, node2 tries to fence node1 with IDRAC. But IDRAC doesn't really work without power. (It works, if power's there and the machine is still unpowered.)
It stucks in a loop with following message:

node2 fence_drac5: Unable to connect/login to fencing device

The Problem is, that the VMs can't start without successful fencing.
Is there a possibillity to limit failed fencing-attempts to e.g. 3 attempts and starting the VMs to node2?

Thanks allot and greetings from Germany!
