644# SCSI DEVICES
645
646# SCSI DEVICE CONFIGURATION
647
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.
652#
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.
661
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.
666
667# The syntax for wiring down devices is:
668
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
677# device cd
678
679# "units" (SCSI logical unit number) that are not specified are
680# treated as if specified as LUN 0.
681
682# All SCSI devices allocate as many units as are required.
