692 # SCSI DEVICE CONFIGURATION
694 # The SCSI subsystem consists of the `base' SCSI code, a number of
695 # high-level SCSI device `type' drivers, and the low-level host-adapter
696 # device drivers. The host adapters are listed in the ISA and PCI
697 # device configuration sections below.
699 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
700 # that a given bus, target, and LUN always come on line as the same
701 # device unit. In earlier versions the unit numbers were assigned
702 # in the order that the devices were probed on the SCSI bus. This
703 # means that if you removed a disk drive, you may have had to rewrite
704 # your /etc/fstab file, and also that you had to be careful when adding
705 # a new disk as it may have been probed earlier and moved your device
706 # configuration around.
708 # This old behavior is maintained as the default behavior. The unit
709 # assignment begins with the first non-wired down unit for a device
710 # type. For example, if you wire a disk as "da3" then the first
711 # non-wired disk will be assigned da4.
713 # The syntax for wiring down devices is:
715 # device scbus0 at ahc0 # Single bus device
716 # device scbus1 at ahc1 bus 0 # Single bus device
717 # device scbus3 at ahc2 bus 0 # Twin bus device
718 # device scbus2 at ahc2 bus 1 # Twin bus device
719 # device da0 at scbus0 target 0 unit 0
720 # device da1 at scbus3 target 1
721 # device da2 at scbus2 target 3
722 # device sa1 at scbus1 target 6
725 # "units" (SCSI logical unit number) that are not specified are
726 # treated as if specified as LUN 0.
728 # All SCSI devices allocate as many units as are required.
