You should only see the bus hang. Some of the older scsi drivers will tend
not to do the right thing. Make sure you have 2.4 and you have drivers using
The right ("budget + time permitting") setup is probably to use FC/AL. It
has more complications in compatibility but you cant really hang the bus,
you can have multiple loops and an electrical disaster cant blow all the
devices on the cable (and yes I've once seen an entire raid5 array blown
by a power problem on the host)
