720# SCSI DEVICES
721
722# SCSI DEVICE CONFIGURATION
723
724# The SCSI subsystem consists of the `base' SCSI code, a number of
725# high-level SCSI device `type' drivers, and the low-level host-adapter
726# device drivers. The host adapters are listed in the ISA and PCI
727# device configuration sections below.
728#
729# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
730# that a given bus, target, and LUN always come on line as the same
731# device unit. In earlier versions the unit numbers were assigned
732# in the order that the devices were probed on the SCSI bus. This
733# means that if you removed a disk drive, you may have had to rewrite
734# your /etc/fstab file, and also that you had to be careful when adding
735# a new disk as it may have been probed earlier and moved your device
736# configuration around.
737
738# This old behavior is maintained as the default behavior. The unit
739# assignment begins with the first non-wired down unit for a device
740# type. For example, if you wire a disk as "da3" then the first
741# non-wired disk will be assigned da4.
742
743# The syntax for wiring down devices is:
744
745# device scbus0 at ahc0 # Single bus device
746# device scbus1 at ahc1 bus 0 # Single bus device
747# device scbus3 at ahc2 bus 0 # Twin bus device
748# device scbus2 at ahc2 bus 1 # Twin bus device
749# device da0 at scbus0 target 0 unit 0
750# device da1 at scbus3 target 1
751# device da2 at scbus2 target 3
752# device sa1 at scbus1 target 6
753# device cd
754
755# "units" (SCSI logical unit number) that are not specified are
756# treated as if specified as LUN 0.
757
758# All SCSI devices allocate as many units as are required.
