DESCRIPTION
this provides a legacy mechanism to add or remove devices by Host, Channel, ID, and Lun. To use, lqecho 'scsi add-single-device 0 1 2 3' > /proc/scsi/scsirq or lqecho 'scsi remove-single-device 0 1 2 3' > /proc/scsi/scsirq with lq0 1 2 3rq replaced by the Host, Channel, Id, and Lun.
NOTE
this seems to be aimed at parallel SCSI. Most modern busses (USB, SATA, Firewire, Fibre Channel, etc) dynamically assign these values to provide a unique identifier and nothing more.
