It really isn't any different than mapping and masking a device for a stand alone host. Just map the device to the desired FA ports, zone all nodes of the cluster to those FA ports on your switch, and then mask all the devices to all cluster nodes. Apart from that just follow the Microsoft documentation for configuring the devices in the cluster.

If your windows clusters is running Windows 2008 there are specific bits to enable on the FAs. This is covered in the ESM.
