Thanks. I have read the link you provide, there is another link which tells me to pass a NPIV discovery lun as a disk, this is seen as a local direct access disk in windows. RAC and Failure Cluster both consider this pass through disk as local disk, not a share disk, and the setup process failed. Hyper-v provides a virtual Fiber Channel implementation, so I wondering if kvm has the same solution like it.
