Dangerous? Why? I believe that (at least as long as you do not try to add a device that's already been added/initalized) you can quite safely write a simple program/script that tries to add all devices (well, just those that make sense ie no IDs greater than 8 on non-wide bus etc) and run it at any time. There might be some issues I'm not aware of, like doing this repeatedly many times one right after another, but if it's just a script ran once...

The aforementioned script would do all this for you, I think.

And I routinely hot-plug (on and off) ordinary SCSI-2 drives (numerous types: IBM, Fujitsu, Quantum, Seagate) to my old no name NCR 810. No probs so far (I've been doing this for more than a year now, AFAIR). From time to time SCSI bus gets reset but I believe it's due to my extremaly careless attitude towards termination; 53c810 seems to be very permissive when it comes to termination but it has its limits :)

Some call like, say, rescan_and_register_new_scsi_devs()? I don't think it's necessary since it seems all stuff like this can be done using user-level code.
