Do failover clusters require Storport-controlled disks?

I have developed an MPIO-like product that virtualizes disks on a virtual (non-Storport) bus in Windows. Within Failover Cluster Manager In Windows Server, these disks cannot be added to a cluster. If the disks are just attached to an FC HBA (with a Storport miniport driver), they can be added to a cluster. So, do failover clusters require Storport-controlled disks?

The main reason I'm asking this question is I've run the storage tests in the 'Validate Cluster' wizard in Failover Cluster Manager. When the disks are simply attached to the FC HBA, the 'List Disks' result displays the 'Stack Type' as 'Stor Port'. When I virtualize the disks in my product, the 'Stack Type' changes to 'full port or multipath I/O'. This is the only difference/clue I can find in any logs to explain why the 'Add Disk' widget in Failover Cluster Manager won't add the disks.

Thanks
