this simple script works fine for me:

,----
| #!/bin/sh
| 
| for HOST in 0 1 2 3 4 5 6; do
|   for CHANNEL in 0 1; do
|     for ID in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do
|       for LUN in 0 1 2 3 4 5 6 7; do
|         echo -ne "scanning: ${HOST} ${CHANNEL} ${ID} ${LUN}  \r"
|         echo "scsi remove-single-device ${HOST} ${CHANNEL} ${ID} ${LUN}" > /proc/scsi/scsi
|         echo "scsi add-single-device ${HOST} ${CHANNEL} ${ID} ${LUN}" > /proc/scsi/scsi
|       done
|     done
|   done
| done
| 
| cat /proc/scsi/scsi
