The host adapters are listed in the ISA and PCI 647# device configuration sections below. 648# 649# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 650# that a given bus, target, and LUN always come on line as the same 651# device unit. In earlier versions the unit numbers were assigned 652# in the order that the devices were probed on the SCSI bus. This 653# means that if you removed a disk drive, you may have had to rewrite 654# your /etc/fstab file, and also that you had to be careful when adding 655# a new disk as it may have been probed earlier and moved your device 656# configuration around. 657 658# This old behavior is maintained as the default behavior. The unit 659# assignment begins with the first non-wired down unit for a device 660# type. For example, if you wire a disk as "da3" then the first 661# non-wired disk will be assigned da4. 662 663# The syntax for wiring down devices is: 664 665# controller scbus0 at ahc0 # Single bus device 666# controller scbus1 at ahc1 bus 0 # Single bus device 667# controller scbus3 at ahc2 bus 0 # Twin bus device 668# controller scbus2 at ahc2 bus 1 # Twin bus device 669# disk da0 at scbus0 target 0 unit 0 670# disk da1 at scbus3 target 1 671# disk da2 at scbus2 target 3 672# tape st1 at scbus1 target 6 673# device cd0 at scbus? 674 675# "units" (SCSI logical unit number) that are not specified are 676# treated as if specified as LUN 0. 677 678# All SCSI devices allocate as many units as are required. 679 680# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 681# configuration and doesn't have to be explicitly configured. 682 683controller scbus0 #base SCSI code 684device ch0 #SCSI media changers 685device da0 #SCSI direct access devices (aka disks) 686device sa0 #SCSI tapes 687device cd0 #SCSI CD-ROMs 688#device od0 #SCSI optical disk 689device pass0 #CAM passthrough driver 690 691# The previous devices (ch, da, st, cd) are recognized by config. 692# config doesn't (and shouldn't) know about these newer ones, 693# so we have to specify that they are on a SCSI bus with the "at scbus?" 694# clause. 695 696device pt0 at scbus? # SCSI processor type 697device sctarg0 at scbus? # SCSI target 698 699# CAM OPTIONS: 700# debugging options: 701# -- NOTE -- If you specify one of the bus/target/lun options, you must 702# specify them all! 703# CAMDEBUG: When defined enables debugging macros 704# CAM_DEBUG_BUS: Debug the given bus.
