221519d15cSJohn Baldwin# Large block comments should begin and end with a line containing only a
231519d15cSJohn Baldwin# comment character.
241519d15cSJohn Baldwin#
251519d15cSJohn Baldwin# To describe a particular object, a block comment (if it exists) should
261519d15cSJohn Baldwin# come first.  Next should come device, options, and hints lines in that
271519d15cSJohn Baldwin# order.  All device and option lines must be described by a comment that
281519d15cSJohn Baldwin# doesn't just expand the device or option name.  Use only a concise
291519d15cSJohn Baldwin# comment on the same line if possible.  Very detailed descriptions of
301519d15cSJohn Baldwin# devices and subsystems belong in man pages.
311519d15cSJohn Baldwin#
32eb4f7a81SNate Lawson# A space followed by a tab separates 'options' from an option name.  Two
331519d15cSJohn Baldwin# spaces followed by a tab separate 'device' from a device name.  Comments
341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.
351519d15cSJohn Baldwin# To comment out a negative option that disables code and thus should not be
36eb4f7a81SNate Lawson# enabled for LINT builds, precede 'options' with "#!".

9596a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
9606a8d6623SGarrett Wollman
9616a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
962ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
9636a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
9646a8d6623SGarrett Wollman# device configuration sections below.
9656a8d6623SGarrett Wollman#
966e14eb5a1SGarrett Wollman# It is possible to wire down your SCSI devices so that a given bus,
967e14eb5a1SGarrett Wollman# target, and LUN always come on line as the same device unit.  In
968e14eb5a1SGarrett Wollman# earlier versions the unit numbers were assigned in the order that
969e14eb5a1SGarrett Wollman# the devices were probed on the SCSI bus.  This means that if you
970e14eb5a1SGarrett Wollman# removed a disk drive, you may have had to rewrite your /etc/fstab
971e14eb5a1SGarrett Wollman# file, and also that you had to be careful when adding a new disk
972e14eb5a1SGarrett Wollman# as it may have been probed earlier and moved your device configuration
973e14eb5a1SGarrett Wollman# around.  (See also option GEOM_VOL for a different solution to this
974e14eb5a1SGarrett Wollman# problem.)
975ebc1a0e2SPeter Dufault
976ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
977ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
978700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
979700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
