There are several different SCSI Bus rescan scrips for Linux around.
Google it...

The old way is to do:

echo "scsi add-single-device H C I L" > /proc/scsi/scsi 

(H = host, C = channel, I = SCSI ID, L = SCSI LUN)

The newer method would be to do:

echo "- - -" > /sys/class/scsi_host/host<ID>/scan

Here is a how-to for CentOS 4 U3 and newer:
