The host adapters are listed in the ISA and PCI 630# device configuration sections below. 631# 632# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 633# that a given bus, target, and LUN always come on line as the same 634# device unit. In earlier versions the unit numbers were assigned 635# in the order that the devices were probed on the SCSI bus. This 636# means that if you removed a disk drive, you may have had to rewrite 637# your /etc/fstab file, and also that you had to be careful when adding 638# a new disk as it may have been probed earlier and moved your device 639# configuration around. 640 641# This old behavior is maintained as the default behavior. The unit 642# assignment begins with the first non-wired down unit for a device 643# type. For example, if you wire a disk as "da3" then the first 644# non-wired disk will be assigned da4. 645 646# The syntax for wiring down devices is: 647 648# device scbus0 at ahc0 # Single bus device 649# device scbus1 at ahc1 bus 0 # Single bus device 650# device scbus3 at ahc2 bus 0 # Twin bus device 651# device scbus2 at ahc2 bus 1 # Twin bus device 652# device da0 at scbus0 target 0 unit 0 653# device da1 at scbus3 target 1 654# device da2 at scbus2 target 3 655# device sa1 at scbus1 target 6 656# device cd 657 658# "units" (SCSI logical unit number) that are not specified are 659# treated as if specified as LUN 0. 660 661# All SCSI devices allocate as many units as are required. 662 663# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 664# configuration and doesn't have to be explicitly configured. 665 666device scbus #base SCSI code 667device ch #SCSI media changers 668device da #SCSI direct access devices (aka disks) 669device sa #SCSI tapes 670device cd #SCSI CD-ROMs 671device pass #CAM passthrough driver 672device sg #Passthrough device (linux scsi generic) 673device pt #SCSI processor type 674device ses #SCSI SES/SAF-TE driver 675device targ #SCSI Target Mode Code 676device targbh #SCSI Target Mode Blackhole Device 677 678# Options for device mapper 679device dm 680device dm_target_crypt 681device dm_target_linear 682device dm_target_striped 683device dm_target_delay 684device dm_target_flakey 685 686# Options for iSCSI 687device iscsi_initiator 688options ISCSI_INITIATOR_DEBUG=8 689 690# CAM OPTIONS: 691# debugging options: 692# -- NOTE -- If you specify one of the bus/target/lun options, you must 693# specify them all! 694# CAMDEBUG: When defined enables debugging macros 695# CAM_DEBUG_BUS: Debug the given bus.
