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 manpages.

341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.

8406a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
8416a8d6623SGarrett Wollman
8426a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
843ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
8446a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
8456a8d6623SGarrett Wollman# device configuration sections below.
8466a8d6623SGarrett Wollman#
847e14eb5a1SGarrett Wollman# It is possible to wire down your SCSI devices so that a given bus,
848e14eb5a1SGarrett Wollman# target, and LUN always come on line as the same device unit.  In
849e14eb5a1SGarrett Wollman# earlier versions the unit numbers were assigned in the order that
850e14eb5a1SGarrett Wollman# the devices were probed on the SCSI bus.  This means that if you
851e14eb5a1SGarrett Wollman# removed a disk drive, you may have had to rewrite your /etc/fstab
852e14eb5a1SGarrett Wollman# file, and also that you had to be careful when adding a new disk
853e14eb5a1SGarrett Wollman# as it may have been probed earlier and moved your device configuration
