I also use: # echo "scsi add-single-device 1 0 1 0" > /proc/scsi/scsi Be Host - Channel - ID - Lun (a reboot also works :)

There iss a script called "rescan_scsi_bus.sh" but it is not part of tan enterprise linux edition. It can be downloaded and uses the same mechanism (even more sophisticated). But the basic command is the echo to the /sys filesystem (or to the /proc, if the driver supports it)
