Yeah linux is unfortunately one of the few unixes that does NOT have device names that map directly to a scsi bus,id,lun of the device. A real shame and very odd given how ide is handled. Of course I think with devfs is did have such devices for scsi, although I don't know if udev does. On the other hand having sda be the first found disk is very handy for booting from software raid1 if a drive fails. It probably wouldn't be to hard to work with even if it didn't though.
