6256a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
6266a8d6623SGarrett Wollman
6276a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
628ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
6296a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
6306a8d6623SGarrett Wollman# device configuration sections below.
6316a8d6623SGarrett Wollman#
632265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
633ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
634ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
635ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
636ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
637ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
638ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
639ebc1a0e2SPeter Dufault# configuration around.
640ebc1a0e2SPeter Dufault
641ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
642ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
643700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
644700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
645ebc1a0e2SPeter Dufault
646ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:
