The host adapters are listed in the ISA and PCI 711# device configuration sections below. 712# 713# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 714# that a given bus, target, and LUN always come on line as the same 715# device unit. In earlier versions the unit numbers were assigned 716# in the order that the devices were probed on the SCSI bus. This 717# means that if you removed a disk drive, you may have had to rewrite 718# your /etc/fstab file, and also that you had to be careful when adding 719# a new disk as it may have been probed earlier and moved your device 720# configuration around. 721 722# This old behavior is maintained as the default behavior. The unit 723# assignment begins with the first non-wired down unit for a device 724# type. For example, if you wire a disk as "da3" then the first 725# non-wired disk will be assigned da4. 726 727# The syntax for wiring down devices is: 728 729# device scbus0 at ahc0 # Single bus device 730# device scbus1 at ahc1 bus 0 # Single bus device 731# device scbus3 at ahc2 bus 0 # Twin bus device 732# device scbus2 at ahc2 bus 1 # Twin bus device 733# device da0 at scbus0 target 0 unit 0 734# device da1 at scbus3 target 1 735# device da2 at scbus2 target 3 736# device sa1 at scbus1 target 6 737# device cd0 at scbus? 738 739# "units" (SCSI logical unit number) that are not specified are 740# treated as if specified as LUN 0. 741 742# All SCSI devices allocate as many units as are required. 743 744# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 745# configuration and doesn't have to be explicitly configured. 746 747device scbus0 #base SCSI code 748device ch0 #SCSI media changers 749device da0 #SCSI direct access devices (aka disks) 750device sa0 #SCSI tapes 751device cd0 #SCSI CD-ROMs 752device pass0 #CAM passthrough driver 753device pt0 #SCSI processor type 754device ses0 #SCSI SES/SAF-TE driver 755 756# CAM OPTIONS: 757# debugging options: 758# -- NOTE -- If you specify one of the bus/target/lun options, you must 759# specify them all! 760# CAMDEBUG: When defined enables debugging macros 761# CAM_DEBUG_BUS: Debug the given bus.
