3206a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
3216a8d6623SGarrett Wollman
3226a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
323ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
3246a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
3256a8d6623SGarrett Wollman# device configuration sections below.
3266a8d6623SGarrett Wollman#
327265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
328ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
329ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
330ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
331ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
332ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
333ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
334ebc1a0e2SPeter Dufault# configuration around.
335ebc1a0e2SPeter Dufault
336ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
337ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
338ebc1a0e2SPeter Dufault# type.  For example, if you wire a disk as "sd3" then the first
339ebc1a0e2SPeter Dufault# non-wired disk will be assigned sd4.
340ebc1a0e2SPeter Dufault
341ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:
