• (TJ) The text below is from drivers/scsi/scsi.c. /* * Usage: echo “scsi add-single-device 0 1 2 3” >/proc/scsi/scsi * with “0 1 2 3” replaced by your “Host Channel Id Lun”. * Consider this feature BETA. * CAUTION: This is not for hotplugging your peripherals. As * SCSI was not designed for this you could damage your * hardware ! * However perhaps it is legal to switch on an * already connected device. It is perhaps not * guaranteed this device doesn’t corrupt an ongoing data transfer. */ For a typical discussion of this topic, see http://jpj.net/~trevor/linux/rescan_scsi.txt.gz.
