The host adapters are listed in the ISA and PCI 639# device configuration sections below. 640# 641# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 642# that a given bus, target, and LUN always come on line as the same 643# device unit. In earlier versions the unit numbers were assigned 644# in the order that the devices were probed on the SCSI bus. This 645# means that if you removed a disk drive, you may have had to rewrite 646# your /etc/fstab file, and also that you had to be careful when adding 647# a new disk as it may have been probed earlier and moved your device 648# configuration around. 649 650# This old behavior is maintained as the default behavior. The unit 651# assignment begins with the first non-wired down unit for a device 652# type. For example, if you wire a disk as "da3" then the first 653# non-wired disk will be assigned da4. 654 655# The syntax for wiring down devices is: 656 657# device scbus0 at ahc0 # Single bus device 658# device scbus1 at ahc1 bus 0 # Single bus device 659# device scbus3 at ahc2 bus 0 # Twin bus device 660# device scbus2 at ahc2 bus 1 # Twin bus device 661# device da0 at scbus0 target 0 unit 0 662# device da1 at scbus3 target 1 663# device da2 at scbus2 target 3 664# device sa1 at scbus1 target 6 665# device cd 666 667# "units" (SCSI logical unit number) that are not specified are 668# treated as if specified as LUN 0. 669 670# All SCSI devices allocate as many units as are required. 671 672# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 673# configuration and doesn't have to be explicitly configured. 674 675device scbus #base SCSI code 676device ch #SCSI media changers 677device da #SCSI direct access devices (aka disks) 678device sa #SCSI tapes 679device cd #SCSI CD-ROMs 680device pass #CAM passthrough driver 681device sg #Passthrough device (linux scsi generic) 682device pt #SCSI processor type 683device ses #SCSI SES/SAF-TE driver 684device targ #SCSI Target Mode Code 685device targbh #SCSI Target Mode Blackhole Device 686 687# Options for device mapper 688device dm 689device dm_target_crypt 690device dm_target_linear 691device dm_target_striped 692device dm_target_delay 693device dm_target_flakey 694 695# Options for iSCSI 696device iscsi_initiator 697options ISCSI_INITIATOR_DEBUG=8 698 699# 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.
