The host adapters are listed in the ISA and PCI 337# device configuration sections below. 338# 339# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 340# that a given bus, target, and LUN always come on line as the same 341# device unit. In earlier versions the unit numbers were assigned 342# in the order that the devices were probed on the SCSI bus. This 343# means that if you removed a disk drive, you may have had to rewrite 344# your /etc/fstab file, and also that you had to be careful when adding 345# a new disk as it may have been probed earlier and moved your device 346# configuration around. 347 348# This old behavior is maintained as the default behavior. The unit 349# assignment begins with the first non-wired down unit for a device 350# type. For example, if you wire a disk as "sd3" then the first 351# non-wired disk will be assigned sd4. 352 353# The syntax for wiring down devices is: 354 355# controller scbus0 at ahc0 # Single bus device 356# controller scbus1 at ahc1 bus 0 # Single bus device 357# controller scbus3 at ahc2 bus 0 # Twin bus device 358# controller scbus2 at ahc2 bus 1 # Twin bus device 359# disk sd0 at scbus0 target 0 unit 0 360# disk sd1 at scbus3 target 1 361# disk sd2 at scbus2 target 3 362# tape st1 at scbus1 target 6 363# device cd0 at scbus? 364 365# "units" (SCSI logical unit number) that are not specified are 366# treated as if specified as LUN 0. 367 368# All SCSI devices allocate as many units as are required. 369 370# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 371# configuration and doesn't have to be explicitly configured. 372 373controller scbus0 #base SCSI code 374device ch0 #SCSI media changers 375device sd0 #SCSI disks 376device st0 #SCSI tapes 377device cd0 #SCSI CD-ROMs 378device od0 #SCSI optical disk 379 380# The previous devices (ch, sd, st, cd) are recognized by config. 381# config doesn't (and shouldn't) know about these newer ones, 382# so we have to specify that they are on a SCSI bus with the "at scbus?" 383# clause. 384 385device worm0 at scbus? # SCSI worm 386device pt0 at scbus? # SCSI processor type 387device sctarg0 at scbus? # SCSI target 388 389# SCSI OPTIONS: 390 391# SCSIDEBUG: When defined enables debugging macros 392# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 393# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 394# of only when booting verbosely. 395options SCSIDEBUG 396#options NO_SCSI_SENSE 397options SCSI_REPORT_GEOMETRY 398 399# Options for the `od' optical disk driver: 400# 401# If drive returns sense key as 0x02 with vendor specific additional 402# sense code (ASC) and additional sense code qualifier (ASCQ), or 403# illegal ASC and ASCQ.
