  Every nice simple rule has its exception, it seems.  If you connect
a narrow device to a wide bus between the controller and a wide
device, with a wide-narrow adapter that terminates the wide aprt of
the bus, then you only have a narrow data path available from the
controller to the wide device.  [This is not the scenario that Russ
was responding to, and its fix involves rearranging devices rather
than installing a second host adapter.]



  There should probably be a SCSI FAQ around somewhere.  Try

  http://www.storagedimensions.com/support/faq/faqscsi.html

or

  http://www.lib.ox.ac.uk/internet/news/faq/archive/scsi-faq.part1.html
and
  http://www.lib.ox.ac.uk/internet/news/faq/archive/scsi-faq.part2.html

and only then should you (carefully) proceed to

  http://www.progress.demon.co.uk/Fun/scsi-faq.html

which is of largely historical entertainment value.
