I stand corrected.  Although I must point out he did say "new" system :-)

I thought you could do this anyway?  I've done it frequently on other
OS', and assumed you could do the same under FreeBSD.  Can't the scsi(8)
command be used to reprobe the bus when a device has been added or
removed?  The scu command under Ultrix/DUnix can do this, and I think it
can be done under HP-UX as well.
