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