This is an RFE to provide support for generic shared disks such as multi-initiator SCSI disks, and virtual shared disks provided by VMware, libvirt and RHEV.

Currently, the Fiberchannel backend is the only way of providing shared SCSI disk capability, however it is not usable with other kinds of generic shared disks as it executes specific tests in k8s.io/kubernetes/pkg/volume/fc/fc_util.go to check that a real FC disk underlies the PV.

As FC disks are simply a special case of shared disk, it would seem that a generic shared disk driver would be simple to implement, simply by stripping out the FC-specific checks in the existing FC driver.
