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

I think it contains something like this:

echo "- - -" > scan

Did you google the subject line of your question first? If you did you need to say so and explain why you couldn't find the answer. If you hover over a downvote arrow it shows "does not show any research effort" as a primary reason to downvote a question! – Caleb Jul 29 '11 at 7:42
On the other hand, I was searching this site for the same question, as I thought here would likely have the best information, being community-voted and all. Why not be the canonical answer for this question on the Internet? (Note: the accepted answer below worked in Debian too: my older installation of Debian had a different special file. I don't think it's unreasonable to have such Googlable questions here.) – Paul Stephenson Oct 16 '11 at 19:02

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

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

Here is a short article.
