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. -- Doug Goldstein
