Both LVM volumes and SCSI LUNs have a globally unique
identifier associated with them. It is useful to be able
to query this identifier to then perform disk locking,
rather than try to figure out a stable pathname.

Would it not be better to call methods from within libdevmapper and
libblkid than relying on a callout? Its also worth noting that iSCSI
provides a GUID for the volume as well.
