5206a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
5216a8d6623SGarrett Wollman
5226a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
523ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
5246a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
5256a8d6623SGarrett Wollman# device configuration sections below.
5266a8d6623SGarrett Wollman#
527265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
528ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
529ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
530ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
531ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
532ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
533ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
534ebc1a0e2SPeter Dufault# configuration around.
535ebc1a0e2SPeter Dufault
536ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
537ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
538ebc1a0e2SPeter Dufault# type.  For example, if you wire a disk as "sd3" then the first
539ebc1a0e2SPeter Dufault# non-wired disk will be assigned sd4.
540ebc1a0e2SPeter Dufault
541ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:

11393b577e1fSJordan K. Hubbard#
11403b577e1fSJordan K. Hubbard# The exact values used for rp0 depend on how many boards you have
11413b577e1fSJordan K. Hubbard# in the system.  The manufacturer's sample configs are listed as:
11423b577e1fSJordan K. Hubbard#
11433b577e1fSJordan K. Hubbard#   Comtrol Rocketport ISA single card

11473b577e1fSJordan K. Hubbard#   second installed at 0x180, then you should add the following to
11483b577e1fSJordan K. Hubbard#   your kernel configuration file:
11493b577e1fSJordan K. Hubbard#
11503b577e1fSJordan K. Hubbard#               device  rp0     at isa? port 0x100 tty

11523b577e1fSJordan K. Hubbard#
11533b577e1fSJordan K. Hubbard#   For 4 ISA cards, it might be something like this:

146916094866SJulian Elischer#                           will NOT shrink.  To restrict the number of queue
