Mr. Kwong,

There is no automated way of re-scanning the scsi bus. You can manually
probe specific scsi id's that your new targets are at or might be at. 
Syntax is..

    echo "scsi add-single-device c b t u" > /proc/scsi/scsi

Where:  c = channel, b = bus, t = scsi id, u = LUN. So, for example, if
you just plugged in a target into scsi id 3, do the following.

    echo "scsi add-single-device 0 0 3 0" > /proc/scsi/scsi
