235 utility is designed to provide a way for users to access and control the
242 can cause a loss of data and/or system crashes if used improperly.
244 expert users are encouraged to exercise caution when using this command.
245 Novice users should stay away from this utility.
249 utility has a number of primary functions, many of which support an optional
251 A device identifier can take one of three forms:
254 Specify a device name and unit number combination, like "da5" or "cd3".
256 Specify a bus number and target id.
257 The bus number can be determined from
259 .Dq camcontrol devlist .
260 The lun defaults to 0.
262 Specify the bus, target and lun for a device.
266 The device identifier, if it is specified,
268 come immediately after the function name, and before any generic or
269 function-specific arguments.
274 arguments described below will override any device name or unit number
275 specified beforehand.
282 override a specified bus:target or bus:target:lun, however.
286 primary functions support these generic arguments:
289 SCSI command retry count.
290 In order for this to work, error recovery
294 Instruct the kernel to perform generic SCSI error recovery for the given
296 This is needed in order for the retry count
299 Other than retrying commands, the generic error recovery in
300 the code will generally attempt to spin up drives that are not spinning.
301 It may take some other actions, depending upon the sense code returned from

318 List all physical devices (logical units) attached to the CAM subsystem.
319 This also includes a list of peripheral drivers attached to each device.
322 argument, SCSI bus number, adapter name and unit numbers are printed as
325 List all peripheral drivers attached to a given physical device (logical
328 Send the SCSI test unit ready (0x00) command to the given device.
331 utility will report whether the device is ready or not.
333 Send a SCSI inquiry command (0x12) to a device.
336 will print out the standard inquiry data, device serial number, and
337 transfer rate information.
338 The user can specify that only certain types of
339 inquiry data be printed:
342 Get the standard inquiry data.
344 Print out the serial number.
345 If this flag is the only one specified,
347 will not print out "Serial Number" before the value returned by the drive.
348 This is to aid in script writing.
350 Print out transfer rate information.
353 Send a ATA identify command (0xec) to a device.
355 Send the SCSI REPORT LUNS (0xA0) command to the given device.
358 will print out the list of logical units (LUNs) supported by the target device.
359 There are a couple of options to modify the output:
362 Just print out a count of LUNs, not the actual LUN numbers.
364 Just print out the LUNs, and don't print out the count.
365 .It Fl r Ar reporttype
366 Specify the type of report to request from the target:
367 .Bl -tag -width 012345678
369 Return the default report.
373 Most targets will support this report if they support the REPORT LUNS
376 Return only well known LUNs.
378 Return all available LUNs.
383 will try to print out LUN numbers in a reasonable format.
384 It can understand the peripheral, flat, LUN and extended LUN formats.
386 Send the SCSI READ CAPACITY command to the given device and display
388 If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
389 action will be sent to obtain the full size of the device.
392 will print out the last logical block of the device, and the blocksize of
394 To modify the output format, use the following options:
397 Just print out the blocksize, not the last block or device size.
398 This cannot be used with
403 Print out the device size in human readable (base 2, 1K == 1024) format.
406 and cannot be used with
411 Print out the device size in human readable (base 10, 1K == 1000) format.
413 Print out the number of blocks in the device instead of the last logical
416 Quiet, print out the numbers only (separated by a comma if
422 Print out the last logical block or the size of the device only, and omit
426 Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
429 Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
432 Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
433 start bit set and the load/eject bit set.
435 Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
436 start bit cleared and the load/eject bit set.
438 Tell the kernel to scan all busses in the system (with the
440 argument), the given bus (XPT_SCAN_BUS), or bus:target:lun
441 (XPT_SCAN_LUN) for new devices or devices that have gone away.
443 may specify a scan of all busses, a single bus, or a lun.
445 on a target is not supported.
447 Tell the kernel to reset all busses in the system (with the
449 argument) or the given bus (XPT_RESET_BUS) by issuing a SCSI bus
450 reset for that bus, or to reset the given bus:target:lun
451 (XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
452 connecting to that device.
453 Note that this can have a destructive impact
456 Send the SCSI READ DEFECT DATA (10) command (0x37) to the given device, and
457 print out any combination of: the total number of defects, the primary
458 defect list (PLIST), and the grown defect list (GLIST).
461 The three format options are:
463 to print out the list as logical blocks,
465 to print out the list in bytes from index format, and
467 to print out the list in physical sector format.
468 The format argument is
470 Most drives support the physical sector format.
472 support the logical block format.
473 Many drives, if they do not support the
474 requested format, return the data in an alternate format, along with sense
475 information indicating that the requested data format is not supported.
479 attempts to detect this, and print out whatever format the drive returns.
480 If the drive uses a non-standard sense code to report that it does not
481 support the requested format,
483 will probably see the error as a failure to complete the request.
485 Print out the grown defect list.
486 This is a list of bad blocks that have
487 been remapped since the disk left the factory.
489 Print out the primary defect list.
498 will print out the number of defects given in the READ DEFECT DATA header
499 returned from the drive.
500 Some drives will report 0 defects if neither the primary or grown defect
503 Allows the user to display and optionally edit a SCSI mode page.
505 page formats are located in
506 .Pa /usr/share/misc/scsi_modes .
507 This can be overridden by specifying a different file in the
509 environment variable.
512 command takes several arguments:
515 Disable block descriptors for mode sense.
517 Displays mode page data in binary format.
519 This flag allows the user to edit values in the mode page.
521 either edit mode page values with the text editor pointed to by his
523 environment variable, or supply mode page values via standard input, using
526 uses to display mode page values.
527 The editor will be invoked if
529 detects that standard input is terminal.
531 Lists all available mode pages.
532 .It Fl m Ar mode_page
533 This specifies the number of the mode page the user would like to view
535 This argument is mandatory unless

541 .Bl -tag -width xxx -compact
553 Allows the user to send an arbitrary ATA or SCSI CDB to any device.
556 function requires the
558 argument to specify SCSI CDB or the
560 argument to specify ATA Command Block registers values.
561 Other arguments are optional, depending on
563 The command and data specification syntax is documented
566 NOTE: If the CDB specified causes data to be transferred to or from the
567 SCSI device in question, you MUST specify either
572 .It Fl a Ar cmd Op args
573 This specifies the content of 12 ATA Command Block registers (command,

602 11 result registers will be written to standard output in hex.
605 Allows the user to send an arbitrary Serial
606 Management Protocol (SMP) command to a device.
609 function requires the
611 argument to specify the SMP request to be sent, and the
613 argument to specify the format of the SMP response.
614 The syntax for the SMP request and response arguments is documented in
617 Note that SAS adapters that support SMP passthrough (at least the currently
618 known adapters) do not accept CRC bytes from the user in the request and do
619 not pass CRC bytes back to the user in the response.
620 Therefore users should not include the CRC bytes in the length of the
621 request and not expect CRC bytes to be returned in the response.
623 .It Fl r Ar len Ar fmt Op args
624 This specifies the size of the SMP request, without the CRC bytes, and the
625 SMP request format. If the format is
628 bytes of data will be read from standard input and written as the SMP

779 WARNING: enabling debugging printfs currently
780 causes an EXTREME number of kernel printfs.
781 You may have difficulty
782 turning off the debugging printfs once they start, since the kernel will be
783 busy printing messages and unable to service other requests quickly.
786 function takes a number of arguments:

813 bus turns on debugging printfs for all devices on that bus.)
816 Show or set the number of "tagged openings" or simultaneous transactions
817 we attempt to queue to a particular device.
820 command, with no command-specific arguments (i.e., only generic arguments)
821 prints out the "soft" maximum number of transactions that can be queued to
822 the device in question.
823 For more detailed information, use the
825 argument described below.
828 Set the number of tags for the given device.
829 This must be between the
830 minimum and maximum number set in the kernel quirk table.
832 most devices that support tagged queueing is a minimum of 2 and a maximum
834 The minimum and maximum values for a given device may be
835 determined by using the
842 subcommand is described below.
844 Be quiet, and do not report the number of tags.
845 This is generally used when
846 setting the number of tags.
848 The verbose flag has special functionality for the
853 to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
856 This is the amount of capacity for transactions queued to a given device.
858 This is the number of transactions currently queued to a device.
860 This is the kernel queue space for transactions.
861 This count usually mirrors
862 dev_openings except during error recovery operations when
863 the device queue is frozen (device is not allowed to receive
864 commands), the number of dev_openings is reduced, or transaction
867 This is the number of transactions waiting in the kernel queue for capacity
869 This number is usually zero unless error recovery is in
872 The held count is the number of CCBs held by peripheral drivers that have
873 either just been completed or are about to be released to the transport
874 layer for service by a device.
875 Held CCBs reserve capacity on a given

879 queued to a device at once.
882 value above cannot go below this number.
883 The default value for

887 This is the "hard" maximum number of transactions that can be queued to a
891 value cannot go above this number.
892 The default value for
894 is 255, although it may be set higher or lower for various devices.
898 Show or negotiate various communication parameters.
900 not support setting or changing some of these values.
902 Adaptec 174x controllers do not support changing a device's sync rate or
907 will not attempt to set the parameter if the controller indicates that it
908 does not support setting the parameter.
909 To find out what the controller
917 command is described below.
918 Also, some controller drivers do not support
919 setting negotiation parameters, even if the underlying controller supports
921 Some controllers, such as the Advansys wide
922 controllers, support enabling and disabling synchronous negotiation for
923 a device, but do not support setting the synchronous negotiation rate.
926 Attempt to make the negotiation settings take effect immediately by sending
927 a Test Unit Ready command to the device.
929 Show or set current negotiation settings.
931 .It Fl D Ar enable|disable
932 Enable or disable disconnection.
936 Set the command delay offset.
938 Be quiet, do not print anything.
939 This is generally useful when you want to
940 set a parameter, but do not want any status information.
942 Change the synchronization rate for a device.
943 The sync rate is a floating
944 point value specified in MHz.
947 is a legal value, as is
949 .It Fl T Ar enable|disable
950 Enable or disable tagged queueing for a device.
952 Show or set user negotiation settings.
953 The default is to show or set
954 current negotiation settings.

963 .It Fl W Ar bus_width
964 Specify the bus width to negotiate with a device.
967 The only useful values to specify are 8, 16, and 32
969 The controller must support the bus width in question in order for
970 the setting to take effect.
973 In general, sync rate and offset settings will not take effect for a
974 device until a command has been sent to the device.
977 switch above will automatically send a Test Unit Ready to the device so
978 negotiation parameters will take effect.
982 FORMAT UNIT command to the named device.
984 .Em WARNING! WARNING! WARNING!
986 Low level formatting a disk will destroy ALL data on the disk.
988 extreme caution when issuing this command.
989 Many users low-level format
990 disks that do not really need to be low-level formatted.
992 relatively few scenarios that call for low-level formatting a disk.
994 low-level formatting a disk is to initialize the disk after changing
995 its physical sector size.
996 Another reason for low-level formatting a disk
997 is to revive the disk if you are getting "medium format corrupted" errors
998 from the disk in response to read and write requests.
1000 Some disks take longer than others to format.
1001 Users should specify a
1002 timeout long enough to allow the format to complete.
1004 timeout is 3 hours, which should be long enough for most disks.
1006 disks will complete a format operation in a very short period of time
1007 (on the order of 5 minutes or less).
1008 This is often because the drive
1009 does not really support the FORMAT UNIT command -- it just accepts the
1010 command, waits a few minutes and then returns it.

1272 The code that parses the generic command line arguments does not know that
1273 some of the subcommands take multiple arguments.

1277 camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
1280 The sense information from the test unit ready command would not get
1281 printed out, since the first
