EVPD page 0x83 is used to uniquely identify the device. So instead of having each and every program issue a separate SG_IO call to retrieve this information it does make far more sense to display it in sysfs. Some older devices (most notably tapes) will only report reliable information in page 0x80 (Unit Serial Number). So export this in the sysfs attribute 'vpd_pg80'.
