The host adapters are listed in the ISA and PCI 468# device configuration sections below. 469# 470# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 471# that a given bus, target, and LUN always come on line as the same 472# device unit. In earlier versions the unit numbers were assigned 473# in the order that the devices were probed on the SCSI bus. This 474# means that if you removed a disk drive, you may have had to rewrite 475# your /etc/fstab file, and also that you had to be careful when adding 476# a new disk as it may have been probed earlier and moved your device 477# configuration around. 478 479# This old behavior is maintained as the default behavior. The unit 480# assignment begins with the first non-wired down unit for a device 481# type. For example, if you wire a disk as "sd3" then the first 482# non-wired disk will be assigned sd4. 483 484# The syntax for wiring down devices is: 485 486# controller scbus0 at ahc0 # Single bus device 487# controller scbus1 at ahc1 bus 0 # Single bus device 488# controller scbus3 at ahc2 bus 0 # Twin bus device 489# controller scbus2 at ahc2 bus 1 # Twin bus device 490# disk sd0 at scbus0 target 0 unit 0 491# disk sd1 at scbus3 target 1 492# disk sd2 at scbus2 target 3 493# tape st1 at scbus1 target 6 494# device cd0 at scbus? 495 496# "units" (SCSI logical unit number) that are not specified are 497# treated as if specified as LUN 0. 498 499# All SCSI devices allocate as many units as are required. 500 501# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 502# configuration and doesn't have to be explicitly configured. 503 504controller scbus0 #base SCSI code 505device ch0 #SCSI media changers 506device sd0 #SCSI disks 507device st0 #SCSI tapes 508device cd0 #SCSI CD-ROMs 509device od0 #SCSI optical disk 510 511# The previous devices (ch, sd, st, cd) are recognized by config. 512# config doesn't (and shouldn't) know about these newer ones, 513# so we have to specify that they are on a SCSI bus with the "at scbus?" 514# clause. 515 516device worm0 at scbus? # SCSI worm 517device pt0 at scbus? # SCSI processor type 518device sctarg0 at scbus? # SCSI target 519 520# SCSI OPTIONS: 521 522# SCSIDEBUG: When defined enables debugging macros 523# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 524# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 525# of only when booting verbosely. 526options SCSIDEBUG 527#options NO_SCSI_SENSE 528options SCSI_REPORT_GEOMETRY 529 530# Options for the `od' optical disk driver: 531# 532# If drive returns sense key as 0x02 with vendor specific additional 533# sense code (ASC) and additional sense code qualifier (ASCQ), or 534# illegal ASC and ASCQ.
