Thanks for your quick reply.
Yes, after disabling the fence device from the cluster the cluster is able to start normally without it.
But as per my requirement, I can use only one fence device(Brocade Switch). And the moment I add one of the port of this fence device as Instance to the Fence method, it does not allow me to add the other port of the Fence device.
I have attahced an architecture diagram of my setup for your reference.
Also the status of the Service Group is displayed as "disabled", and when ever I try to start I am not able to do so.
Kinldy look into the above issue and help me in resolving it.
Thanks in advance.
