   it at multiple LUNs.  I then moved it to my Sun3/260, and it showed
   up at multiple LUNs.  A Quantum Lightning 730 also shows up at multiple
   At the time I suspected that there was a glitch in the Sun3 SCSI driver.
   I still do, because when the drive shows up at multiple LUNs, for some of
   them I get an "illegal request".  Or the geometry shows zero surfaces.
   Or it doesn't show up at all LUNs.  It seems to depend on which device I
   boot from, although I have not nailed this dependency down.
   Right now I am reworking the Sun3 SCSI driver, and I will be paying
   attention to this problem.  The Sparc esp driver apparently does the same
