How to rescan scsi bus devices?

Question

How can I rescan a scsi bus for new devices under OpenSUSE?

I think it contains something like this:

echo "- - -" > scan

Answer 1

echo "- - -" > /sys/class/scsi_host/host0/scan

_{(Where 0 is the scsi host bus you want to scan.)}

Here is a short article.
