Apply the reprobe to any of the existing scsi control devices (e.g., /dev/rsd0.ctl). That super device is/was supposed to be a back door for a bus with nothing present at power up. Whether or not the reprobe works or hangs your system is a function of host adapter and OS release, and so you are better off with a reboot unless you know it works. -- Peter Dufault (dufault@hda.com) Realtime development, Machine control, HD Associates, Inc.
