646 # SCSI DEVICE CONFIGURATION
648 # The SCSI subsystem consists of the `base' SCSI code, a number of
649 # high-level SCSI device `type' drivers, and the low-level host-adapter
650 # device drivers. The host adapters are listed in the ISA and PCI
651 # device configuration sections below.
653 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
654 # that a given bus, target, and LUN always come on line as the same
655 # device unit. In earlier versions the unit numbers were assigned
656 # in the order that the devices were probed on the SCSI bus. This
657 # means that if you removed a disk drive, you may have had to rewrite
658 # your /etc/fstab file, and also that you had to be careful when adding
659 # a new disk as it may have been probed earlier and moved your device
660 # configuration around.
662 # This old behavior is maintained as the default behavior. The unit
663 # assignment begins with the first non-wired down unit for a device
664 # type. For example, if you wire a disk as "da3" then the first
665 # non-wired disk will be assigned da4.
667 # The syntax for wiring down devices is:
669 # device scbus0 at ahc0 # Single bus device
670 # device scbus1 at ahc1 bus 0 # Single bus device
671 # device scbus3 at ahc2 bus 0 # Twin bus device
672 # device scbus2 at ahc2 bus 1 # Twin bus device
673 # device da0 at scbus0 target 0 unit 0
674 # device da1 at scbus3 target 1
675 # device da2 at scbus2 target 3
676 # device sa1 at scbus1 target 6
