Which software component should set the ID_SCSI_VPD parameter ? Is it udev, now integrated in systemd ? I'm asking this because I haven't found any patch in the udev nor in the systemd repositories that sets the ID_SCSI_VPD parameter. Does this mean that another parameter should be used to restore support for SCSI devices that support the VPD page 0x83 but do not report a WWN in that page ? Or does this mean that systemd should be modified such that it sets the ID_SCSI_VPD parameter ?
