5726a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
5736a8d6623SGarrett Wollman
5746a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
575ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
5766a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
5776a8d6623SGarrett Wollman# device configuration sections below.
5786a8d6623SGarrett Wollman#
579265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
580ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
581ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
582ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
583ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
584ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
585ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
586ebc1a0e2SPeter Dufault# configuration around.
587ebc1a0e2SPeter Dufault
588ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
589ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
590ebc1a0e2SPeter Dufault# type.  For example, if you wire a disk as "sd3" then the first
591ebc1a0e2SPeter Dufault# non-wired disk will be assigned sd4.
592ebc1a0e2SPeter Dufault
593ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:
