The host adapters are listed in the ISA and PCI 645# device configuration sections below. 646# 647# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 648# that a given bus, target, and LUN always come on line as the same 649# device unit. In earlier versions the unit numbers were assigned 650# in the order that the devices were probed on the SCSI bus. This 651# means that if you removed a disk drive, you may have had to rewrite 652# your /etc/fstab file, and also that you had to be careful when adding 653# a new disk as it may have been probed earlier and moved your device 654# configuration around. 655 656# This old behavior is maintained as the default behavior. The unit 657# assignment begins with the first non-wired down unit for a device 658# type. For example, if you wire a disk as "da3" then the first 659# non-wired disk will be assigned da4. 660 661# The syntax for wiring down devices is: 662 663# device scbus0 at ahc0 # Single bus device 664# device scbus1 at ahc1 bus 0 # Single bus device 665# device scbus3 at ahc2 bus 0 # Twin bus device 666# device scbus2 at ahc2 bus 1 # Twin bus device 667# device da0 at scbus0 target 0 unit 0 668# device da1 at scbus3 target 1 669# device da2 at scbus2 target 3 670# device sa1 at scbus1 target 6 671# device cd 672 673# "units" (SCSI logical unit number) that are not specified are 674# treated as if specified as LUN 0. 675 676# All SCSI devices allocate as many units as are required. 677 678# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 679# configuration and doesn't have to be explicitly configured. 680 681device scbus #base SCSI code 682device ch #SCSI media changers 683device da #SCSI direct access devices (aka disks) 684device sa #SCSI tapes 685device cd #SCSI CD-ROMs 686device pass #CAM passthrough driver 687device sg #Passthrough device (linux scsi generic) 688device pt #SCSI processor type 689device ses #SCSI SES/SAF-TE driver 690device targ #SCSI Target Mode Code 691device targbh #SCSI Target Mode Blackhole Device 692 693# Options for device mapper 694device dm 695device dm_target_crypt 696device dm_target_linear 697device dm_target_striped 698device dm_target_delay 699device dm_target_flakey 700 701# Options for iSCSI 702device iscsi_initiator 703options ISCSI_INITIATOR_DEBUG=8 704 705# CAM OPTIONS: 706# debugging options: 707# -- NOTE -- If you specify one of the bus/target/lun options, you must 708# specify them all! 709# CAMDEBUG: When defined enables debugging macros 710# CAM_DEBUG_BUS: Debug the given bus.
