For the super device, we will have to wait until Peter is back again. For the other devices, it's a chicken-and-egg problem. You cannot open a non-configured device, but as soon as you've got a single control device on a SCSI bus, you can fire up a `scsi -f ... -r -t ...' on it. It doesn't actually matter which device you are using (and it didn't since the day when Julian has been creating scsi(8)), so you can e.g. ``scsi -f /dev/rsd0.ctl -r -t 5'' in order to probe SCSI target 5 when there's only sd0 already online. I've been using those reprobes for more than two years now. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
