    Yes, the structure info for each physical disk allows for two (and
    only 2) paths to be represented. But it's pretty limited, describing
    only SCSI-like paths with bus/id/lun only described in the current
    draft. At the same time, there's a per-physical-disk GUID, such
    that if you find the same disk by multiple paths you can tell.
    There's room for enhancment/feedback in this space for certain.
