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. On Wed, Aug 14, 2013 at 10:02 PM, Stefan Hajnoczi <stefanha@gmail.com> wrote:

Hyper-V uses NPIV for virtual Fiber Channel, I have read some article about KVM NPIV, but how can I config it with libvirt? Any body can show me some example?
A web search turns up this:
https://docs.fedoraproject.org/en-US/Fedora/18/html/Virtualization_Administr...
You can use this if the host has a supported Fibre Channel HBA and your image is on a SAN LUN.
From my limited knowledge about this, NPIV itself won't make clustering possible. RAC or Failure Cluster probably still require specific SCSI commands in order to work (like persistent reservations) and that's what needs to be investigated in order to figure out a solution.
