724# SCSI DEVICES
725
726# SCSI DEVICE CONFIGURATION
727
728# The SCSI subsystem consists of the `base' SCSI code, a number of
729# high-level SCSI device `type' drivers, and the low-level host-adapter
730# device drivers. The host adapters are listed in the ISA and PCI
731# device configuration sections below.
732#
733# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
734# that a given bus, target, and LUN always come on line as the same
735# device unit. In earlier versions the unit numbers were assigned
736# in the order that the devices were probed on the SCSI bus. This
737# means that if you removed a disk drive, you may have had to rewrite
738# your /etc/fstab file, and also that you had to be careful when adding
739# a new disk as it may have been probed earlier and moved your device
740# configuration around.
741
742# This old behavior is maintained as the default behavior. The unit
743# assignment begins with the first non-wired down unit for a device
744# type. For example, if you wire a disk as "da3" then the first
745# non-wired disk will be assigned da4.
746
747# The syntax for wiring down devices is:
748
749# device scbus0 at ahc0 # Single bus device
750# device scbus1 at ahc1 bus 0 # Single bus device
751# device scbus3 at ahc2 bus 0 # Twin bus device
752# device scbus2 at ahc2 bus 1 # Twin bus device
753# device da0 at scbus0 target 0 unit 0
754# device da1 at scbus3 target 1
755# device da2 at scbus2 target 3
756# device sa1 at scbus1 target 6
757# device cd
758
759# "units" (SCSI logical unit number) that are not specified are
760# treated as if specified as LUN 0.
761
762# All SCSI devices allocate as many units as are required.
