* remotes/armbru/tags/pull-block-2017-02-21:
  hw/i386: Deprecate -drive if=scsi with PC machine types
  hw: Deprecate -drive if=scsi with non-onboard HBAs
  hw/scsi: Concentrate -drive if=scsi auto-create in one place
  hw: Drop superfluous special checks for orphaned -drive
  blockdev: Make orphaned -drive fatal
  blockdev: Improve message for orphaned -drive
  hw/arm/highbank: Default -drive to if=ide instead of if=scsi
  hw: Default -drive to if=none instead of scsi when scsi cannot work
  hw: Default -drive to if=none instead of ide when ide cannot work
  hw/arm/cubieboard hw/arm/xlnx-ep108: Fix units_per_default_bus
  hw: Default -drive to if=ide explicitly where it works

You can connect a SCSI disk with unit ID 6 on the bus #0:
@example
qemu-system-i386 -drive file=file,if=scsi,bus=0,unit=6
