370.Sh DESCRIPTION
371The
372.Nm
373utility is designed to provide a way for users to access and control the
374.Fx
375CAM subsystem.
376.Pp
377The
378.Nm
379utility
380can cause a loss of data and/or system crashes if used improperly.
381Even
382expert users are encouraged to exercise caution when using this command.
383Novice users should stay away from this utility.
384.Pp
385The
386.Nm
387utility has a number of primary functions, many of which support an optional
388device identifier.
389A device identifier can take one of three forms:
390.Bl -tag -width 14n
391.It deviceUNIT
392Specify a device name and unit number combination, like "da5" or "cd3".
393.It bus:target
394Specify a bus number and target id.
395The bus number can be determined from
396the output of
397.Dq camcontrol devlist .
398The lun defaults to 0.
399.It bus:target:lun
400Specify the bus, target and lun for a device.
401(e.g.\& 1:2:0)
402.El
403.Pp
404The device identifier, if it is specified,
405.Em must
406come immediately after the function name, and before any generic or
407function-specific arguments.
408Note that the
409.Fl n
410and
411.Fl u
412arguments described below will override any device name or unit number
413specified beforehand.
414The
415.Fl n
416and
417.Fl u
418arguments will
419.Em not
420override a specified bus:target or bus:target:lun, however.
421.Pp
422Most of the
423.Nm
424primary functions support these generic arguments:
425.Bl -tag -width 14n
426.It Fl C Ar count
427SCSI command retry count.
428In order for this to work, error recovery
429.Pq Fl E
430must be turned on.
431.It Fl E
432Instruct the kernel to perform generic SCSI error recovery for the given
433command.
434This is needed in order for the retry count
435.Pq Fl C
436to be honored.
437Other than retrying commands, the generic error recovery in
438the code will generally attempt to spin up drives that are not spinning.
439It may take some other actions, depending upon the sense code returned from
440the command.
441.It Fl n Ar dev_name
442Specify the device type to operate on, e.g.\& "da", "cd".
443.It Fl Q Ar task_attr
444.Tn SCSI
445task attribute for the command, if it is a
446.Tn SCSI
447command.
448This may be ordered, simple, head, or aca.
449In most cases this is not needed.
450The default is simple, which works with all
451.Tn SCSI
452devices.
453The task attribute may also be specified numerically.
454.It Fl t Ar timeout
455SCSI command timeout in seconds.
456This overrides the default timeout for
457any given command.
458.It Fl u Ar unit_number
459Specify the device unit number, e.g.\& "1", "5".
460.It Fl v
461Be verbose, print out sense information for failed SCSI commands.
462.El
463.Pp
464Primary command functions:
465.Bl -tag -width periphlist
466.It Ic devlist
467List all physical devices (logical units) attached to the CAM subsystem.
468This also includes a list of peripheral drivers attached to each device.
469With the
470.Fl v
471argument, SCSI bus number, adapter name and unit numbers are printed as
472well.
473On the other hand, with the
474.Fl b
475argument, only the bus adapter, and unit information will be printed, and
476device information will be omitted.
477.It Ic periphlist
478List all peripheral drivers attached to a given physical device (logical
479unit).
480.It Ic tur
481Send the SCSI test unit ready (0x00) command to the given device.
482The
483.Nm
484utility will report whether the device is ready or not.
485.It Ic inquiry
486Send a SCSI inquiry command (0x12) to a device.
487By default,
488.Nm
489will print out the standard inquiry data, device serial number, and
490transfer rate information.
491The user can specify that only certain types of
492inquiry data be printed:
493.Bl -tag -width 4n
494.It Fl D
495Get the standard inquiry data.
496.It Fl S
497Print out the serial number.
498If this flag is the only one specified,
499.Nm
500will not print out "Serial Number" before the value returned by the drive.
501This is to aid in script writing.
502.It Fl R
503Print out transfer rate information.
504.El
505.It Ic identify
506Send a ATA identify command (0xec) to a device.
507.It Ic reportluns
508Send the SCSI REPORT LUNS (0xA0) command to the given device.
509By default,
510.Nm
511will print out the list of logical units (LUNs) supported by the target device.
512There are a couple of options to modify the output:
513.Bl -tag -width 14n
514.It Fl c
515Just print out a count of LUNs, not the actual LUN numbers.
516.It Fl l
517Just print out the LUNs, and do not print out the count.
518.It Fl r Ar reporttype
519Specify the type of report to request from the target:
520.Bl -tag -width 012345678
521.It default
522Return the default report.
523This is the
524.Nm
525default.
526Most targets will support this report if they support the REPORT LUNS
527command.
528.It wellknown
529Return only well known LUNs.
530.It all
531Return all available LUNs.
532.El
533.El
534.Pp
535.Nm
536will try to print out LUN numbers in a reasonable format.
537It can understand the peripheral, flat, LUN and extended LUN formats.
538.It Ic readcap
539Send the SCSI READ CAPACITY command to the given device and display
540the results.
541If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
542action will be sent to obtain the full size of the device.
543By default,
544.Nm
545will print out the last logical block of the device, and the blocksize of
546the device in bytes.
547To modify the output format, use the following options:
548.Bl -tag -width 5n
549.It Fl b
550Just print out the blocksize, not the last block or device size.
551This cannot be used with
552.Fl N
553or
554.Fl s .
555.It Fl h
556Print out the device size in human readable (base 2, 1K == 1024) format.
557This implies
558.Fl N
559and cannot be used with
560.Fl q
561or
562.Fl b .
563.It Fl H
564Print out the device size in human readable (base 10, 1K == 1000) format.
565.It Fl l
566Skip sending the SCSI READ CAPACITY (10) command.
567Send only the SCSI READ CAPACITY (16) service action and report
568its results.
569When the two do not match, a quirk is needed to resolve the ambiguity.
570.It Fl N
571Print out the number of blocks in the device instead of the last logical
572block.
573.It Fl q
574Quiet, print out the numbers only (separated by a comma if
575.Fl b
576or
577.Fl s
578are not specified).
579.It Fl s
580Print out the last logical block or the size of the device only, and omit
581the blocksize.
582.El
583.Pp
584Note that this command only displays the information, it does not update
585the kernel data structures.
586Use the
587.Nm
588reprobe subcommand to do that.
589.It Ic start
590Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
591start bit set.
592.It Ic stop
593Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
594start bit cleared.
595.It Ic load
596Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
597start bit set and the load/eject bit set.
598.It Ic eject
599Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
600start bit cleared and the load/eject bit set.
601.It Ic rescan
602Tell the kernel to scan all buses in the system (with the
603.Ar all
604argument), the given bus (XPT_SCAN_BUS), bus:target:lun or device
605(XPT_SCAN_LUN) for new devices or devices that have gone away.
606The user
607may specify a scan of all buses, a single bus, or a lun.
608Scanning all luns
609on a target is not supported.
610.Pp
611If a device is specified by peripheral name and unit number, for instance
612da4, it may only be rescanned if that device currently exists in the CAM EDT
613(Existing Device Table).
614If the device is no longer there (see
615.Nm
616devlist ),
617you must use the bus:target:lun form to rescan it.
618.It Ic reprobe
619Tell the kernel to refresh the information about the device and
620notify the upper layer,
621.Xr GEOM 4 .
622This includes sending the SCSI READ CAPACITY command and updating
623the disk size visible to the rest of the system.
624.It Ic reset
625Tell the kernel to reset all buses in the system (with the
626.Ar all
627argument), the given bus (XPT_RESET_BUS) by issuing a SCSI bus
628reset for that bus, or to reset the given bus:target:lun or device
629(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
630connecting to that device.
631Note that this can have a destructive impact
632on the system.
633.It Ic defects
634Send the
635.Tn SCSI
636READ DEFECT DATA (10) command (0x37) or the
637.Tn SCSI
638READ DEFECT DATA (12) command (0xB7) to the given device, and
639print out any combination of: the total number of defects, the primary
640defect list (PLIST), and the grown defect list (GLIST).
641.Bl -tag -width 11n
642.It Fl f Ar format
643Specify the requested format of the defect list.
644The format argument is
645required.
646Most drives support the physical sector format.
647Some drives
648support the logical block format.
649Many drives, if they do not support the
650requested format, return the data in an alternate format, along with sense
651information indicating that the requested data format is not supported.
652The
653.Nm
654utility
655attempts to detect this, and print out whatever format the drive returns.
656If the drive uses a non-standard sense code to report that it does not
657support the requested format,
658.Nm
659will probably see the error as a failure to complete the request.
660.Pp
661The format options are:
662.Bl -tag -width 9n
663.It block
664Print out the list as logical blocks.
665This is limited to 32-bit block sizes, and isn't supported by many modern
666drives.
667.It longblock
668Print out the list as logical blocks.
669This option uses a 64-bit block size.
670.It bfi
671Print out the list in bytes from index format.
672.It extbfi
673Print out the list in extended bytes from index format.
674The extended format allows for ranges of blocks to be printed.
675.It phys
676Print out the list in physical sector format.
677Most drives support this format.
678.It extphys
679Print out the list in extended physical sector format.
680The extended format allows for ranges of blocks to be printed.
681.El
682.It Fl G
683Print out the grown defect list.
684This is a list of bad blocks that have
685been remapped since the disk left the factory.
686.It Fl P
687Print out the primary defect list.
688This is the list of defects that were present in the factory.
689.It Fl q
690When printing status information with
691.Fl s ,
692only print the number of defects.
693.It Fl s
694Just print the number of defects, not the list of defects.
695.It Fl S Ar offset
696Specify the starting offset into the defect list.
697This implies using the
698.Tn SCSI
699READ DEFECT DATA (12) command, as the 10 byte version of the command
700doesn't support the address descriptor index field.
701Not all drives support the 12 byte command, and some drives that support
702the 12 byte command don't support the address descriptor index field.
703.It Fl X
704Print out defects in hexadecimal (base 16) form instead of base 10 form.
705.El
706.Pp
707If neither
708.Fl P
709nor
710.Fl G
711is specified,
712.Nm
713will print out the number of defects given in the READ DEFECT DATA header
714returned from the drive.
715Some drives will report 0 defects if neither the primary or grown defect
716lists are requested.
717.It Ic modepage
718Allows the user to display and optionally edit a SCSI mode page.
719The mode
720page formats are located in
721.Pa /usr/share/misc/scsi_modes .
722This can be overridden by specifying a different file in the
723.Ev SCSI_MODES
724environment variable.
725The
726.Ic modepage
727command takes several arguments:
728.Bl -tag -width 12n
729.It Fl 6
730Use 6 byte MODE commands instead of default 10 byte.
731Old devices may not support 10 byte MODE commands, while new devices may
732not be able to report all mode pages with 6 byte commands.
733If not specified,
734.Nm
735starts with 10 byte commands and falls back to 6 byte on error.
736.It Fl d
737Disable block descriptors for mode sense.
738.It Fl D
739Display/edit block descriptors instead of mode page.
740.It Fl L
741Use long LBA block descriptors.
742Allows number of LBAs bigger then 2^^32.
743.It Fl b
744Displays mode page data in binary format.
745.It Fl e
746This flag allows the user to edit values in the mode page.
747The user may
748either edit mode page values with the text editor pointed to by his
749.Ev EDITOR
750environment variable, or supply mode page values via standard input, using
751the same format that
752.Nm
753uses to display mode page values.
754The editor will be invoked if
755.Nm
756detects that standard input is terminal.
757.It Fl l
758Lists all available mode pages.
759If specified more then once, also lists subpages.
760.It Fl m Ar page[,subpage]
761This specifies the number of the mode page and optionally subpage the user
762would like to view and/or edit.
763This argument is mandatory unless

778.El
779.El
780.It Ic cmd
781Allows the user to send an arbitrary ATA or SCSI CDB to any device.
782The
783.Ic cmd
784function requires the
785.Fl c
786argument to specify SCSI CDB or the
787.Fl a
788argument to specify ATA Command Block registers values.
789Other arguments are optional, depending on
790the command type.
791The command and data specification syntax is documented
792in
793.Xr cam_cdbparse 3 .
794NOTE: If the CDB specified causes data to be transferred to or from the
795SCSI device in question, you MUST specify either
796.Fl i
797or
798.Fl o .
799.Bl -tag -width 17n
800.It Fl a Ar cmd Op args
801This specifies the content of 12 ATA Command Block registers (command,

809.It Fl f
810Specifies FPDMA (NCQ) protocol to be used for ATA command.
811.It Fl i Ar len Ar fmt
812This specifies the amount of data to read, and how it should be displayed.
813If the format is
814.Sq - ,
815.Ar len
816bytes of data will be read from the device and written to standard output.
817.It Fl o Ar len Ar fmt Op args
818This specifies the amount of data to be written to a device, and the data
819that is to be written.
820If the format is

83011 result registers will be written to standard output in hex.
831.El
832.It Ic smpcmd
833Allows the user to send an arbitrary Serial
834Management Protocol (SMP) command to a device.
835The
836.Ic smpcmd
837function requires the
838.Fl r
839argument to specify the SMP request to be sent, and the
840.Fl R
841argument to specify the format of the SMP response.
842The syntax for the SMP request and response arguments is documented in
843.Xr cam_cdbparse 3 .
844.Pp
845Note that SAS adapters that support SMP passthrough (at least the currently
846known adapters) do not accept CRC bytes from the user in the request and do
847not pass CRC bytes back to the user in the response.
848Therefore users should not include the CRC bytes in the length of the
849request and not expect CRC bytes to be returned in the response.
850.Bl -tag -width 17n
851.It Fl r Ar len Ar fmt Op args
852This specifies the size of the SMP request, without the CRC bytes, and the
853SMP request format.
854If the format is
855.Sq - ,
856.Ar len
857bytes of data will be read from standard input and written as the SMP
858request.
859.It Fl R Ar len Ar fmt Op args
860This specifies the size of the buffer allocated for the SMP response, and
861the SMP response format.
862If the format is
863.Sq - ,
864.Ar len
865bytes of data will be allocated for the response and the response will be
866written to standard output.
867.El

873If the SMP target supports the long response format, the additional data
874will be requested and displayed automatically.
875.Bl -tag -width 8n
876.It Fl l
877Request the long response format only.
878Not all SMP targets support the long response format.
879This option causes
880.Nm
881to skip sending the initial report general request without the long bit set
882and only issue a report general request with the long bit set.
883.El
884.It Ic smppc
885Allows the user to issue the Serial Management Protocol (SMP) PHY Control
886command to a device.
887This function should be used with some caution, as it can render devices
888inaccessible, and could potentially cause data corruption as well.
889The
890.Fl p
891argument is required to specify the PHY to operate on.
892.Bl -tag -width 17n
893.It Fl p Ar phy
894Specify the PHY to operate on.
895This argument is required.
896.It Fl l

899For the PHY Control command, this currently only affects whether the
900request length is set to a value other than 0.
901.It Fl o Ar operation
902Specify a PHY control operation.
903Only one
904.Fl o
905operation may be specified.
906The operation may be specified numerically (in decimal, hexadecimal, or octal)
907or one of the following operation names may be specified:

920Send the CLEAR ERROR LOG command.
921This clears the error log counters for the specified phy.
922.It clearaffiliation
923Send the CLEAR AFFILIATION command.
924This clears the affiliation from the STP initiator port with the same SAS
925address as the SMP initiator that requests the clear operation.
926.It sataportsel
927Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
928This will cause a SATA port selector to use the given phy as its active phy
929and make the other phy inactive.
930.It clearitnl
931Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
932.It setdevname

1004.It Ic debug
1005Turn on CAM debugging printfs in the kernel.
1006This requires options CAMDEBUG
1007in your kernel config file.
1008WARNING: enabling debugging printfs currently
1009causes an EXTREME number of kernel printfs.
1010You may have difficulty
1011turning off the debugging printfs once they start, since the kernel will be
1012busy printing messages and unable to service other requests quickly.
1013The
1014.Ic debug
1015function takes a number of arguments:
1016.Bl -tag -width 18n
1017.It Fl I

1037.It bus Ns Op :target Ns Op :lun
1038Turn on debugging for the given bus, target or lun.
1039If the lun or target
1040and lun are not specified, they are wildcarded.
1041(i.e., just specifying a
1042bus turns on debugging printfs for all devices on that bus.)
1043.El
1044.It Ic tags
1045Show or set the number of "tagged openings" or simultaneous transactions
1046we attempt to queue to a particular device.
1047By default, the
1048.Ic tags
1049command, with no command-specific arguments (i.e., only generic arguments)
1050prints out the "soft" maximum number of transactions that can be queued to
1051the device in question.
1052For more detailed information, use the
1053.Fl v
1054argument described below.
1055.Bl -tag -width 7n
1056.It Fl N Ar tags
1057Set the number of tags for the given device.
1058This must be between the
1059minimum and maximum number set in the kernel quirk table.
1060The default for
1061most devices that support tagged queueing is a minimum of 2 and a maximum
1062of 255.
1063The minimum and maximum values for a given device may be
1064determined by using the
1065.Fl v
1066switch.
1067The meaning of the
1068.Fl v
1069switch for this
1070.Nm
1071subcommand is described below.
1072.It Fl q
1073Be quiet, and do not report the number of tags.
1074This is generally used when
1075setting the number of tags.
1076.It Fl v
1077The verbose flag has special functionality for the
1078.Em tags
1079argument.
1080It causes
1081.Nm
1082to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
1083.Bl -tag -width 13n
1084.It dev_openings
1085This is the amount of capacity for transactions queued to a given device.
1086.It dev_active
1087This is the number of transactions currently queued to a device.
1088.It devq_openings
1089This is the kernel queue space for transactions.
1090This count usually mirrors
1091dev_openings except during error recovery operations when
1092the device queue is frozen (device is not allowed to receive
1093commands), the number of dev_openings is reduced, or transaction
1094replay is occurring.
1095.It devq_queued
1096This is the number of transactions waiting in the kernel queue for capacity
1097on the device.
1098This number is usually zero unless error recovery is in
1099progress.
1100.It held
1101The held count is the number of CCBs held by peripheral drivers that have
1102either just been completed or are about to be released to the transport
1103layer for service by a device.
1104Held CCBs reserve capacity on a given
1105device.
1106.It mintags
1107This is the current "hard" minimum number of transactions that can be
1108queued to a device at once.
1109The
1110.Ar dev_openings
1111value above cannot go below this number.
1112The default value for
1113.Ar mintags
1114is 2, although it may be set higher or lower for various devices.
1115.It maxtags
1116This is the "hard" maximum number of transactions that can be queued to a
1117device at one time.
1118The
1119.Ar dev_openings
1120value cannot go above this number.
1121The default value for
1122.Ar maxtags
1123is 255, although it may be set higher or lower for various devices.
1124.El
1125.El
1126.It Ic negotiate
1127Show or negotiate various communication parameters.
1128Some controllers may
1129not support setting or changing some of these values.
1130For instance, the
1131Adaptec 174x controllers do not support changing a device's sync rate or
1132offset.
1133The
1134.Nm
1135utility
1136will not attempt to set the parameter if the controller indicates that it
1137does not support setting the parameter.
1138To find out what the controller
1139supports, use the
1140.Fl v
1141flag.
1142The meaning of the
1143.Fl v
1144flag for the
1145.Ic negotiate
1146command is described below.
1147Also, some controller drivers do not support
1148setting negotiation parameters, even if the underlying controller supports
1149negotiation changes.
1150Some controllers, such as the Advansys wide
1151controllers, support enabling and disabling synchronous negotiation for
1152a device, but do not support setting the synchronous negotiation rate.
1153.Bl -tag -width 17n
1154.It Fl a
1155Attempt to make the negotiation settings take effect immediately by sending
1156a Test Unit Ready command to the device.
1157.It Fl c

1159This is the default.
1160.It Fl D Ar enable|disable
1161Enable or disable disconnection.
1162.It Fl M Ar mode
1163Set ATA mode.
1164.It Fl O Ar offset
1165Set the command delay offset.
1166.It Fl q
1167Be quiet, do not print anything.
1168This is generally useful when you want to
1169set a parameter, but do not want any status information.
1170.It Fl R Ar syncrate
1171Change the synchronization rate for a device.
1172The sync rate is a floating
1173point value specified in MHz.
1174So, for instance,
1175.Sq 20.000
1176is a legal value, as is
1177.Sq 20 .
1178.It Fl T Ar enable|disable
1179Enable or disable tagged queueing for a device.
1180.It Fl U
1181Show or set user negotiation settings.
1182The default is to show or set
1183current negotiation settings.
1184.It Fl v
1185The verbose switch has special meaning for the
1186.Ic negotiate
1187subcommand.
1188It causes
1189.Nm
1190to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the
1191controller driver.
1192.It Fl W Ar bus_width
1193Specify the bus width to negotiate with a device.
1194The bus width is
1195specified in bits.
1196The only useful values to specify are 8, 16, and 32
1197bits.
1198The controller must support the bus width in question in order for
1199the setting to take effect.
1200.El
1201.Pp
1202In general, sync rate and offset settings will not take effect for a
1203device until a command has been sent to the device.
1204The
1205.Fl a
1206switch above will automatically send a Test Unit Ready to the device so
1207negotiation parameters will take effect.
1208.It Ic format
1209Issue the
1210.Tn SCSI
1211FORMAT UNIT command to the named device.
1212.Pp
1213.Em WARNING! WARNING! WARNING!
1214.Pp
1215Low level formatting a disk will destroy ALL data on the disk.
1216Use
1217extreme caution when issuing this command.
1218Many users low-level format
1219disks that do not really need to be low-level formatted.
1220There are
1221relatively few scenarios that call for low-level formatting a disk.
1222One reason for
1223low-level formatting a disk is to initialize the disk after changing
1224its physical sector size.
1225Another reason for low-level formatting a disk
1226is to revive the disk if you are getting "medium format corrupted" errors
1227from the disk in response to read and write requests.
1228.Pp
1229Some disks take longer than others to format.
1230Users should specify a
1231timeout long enough to allow the format to complete.
1232The default format
1233timeout is 3 hours, which should be long enough for most disks.
1234Some hard
1235disks will complete a format operation in a very short period of time
1236(on the order of 5 minutes or less).
1237This is often because the drive
1238does not really support the FORMAT UNIT command -- it just accepts the
1239command, waits a few minutes and then returns it.
1240.Pp
1241The
1242.Sq format
1243subcommand takes several arguments that modify its default behavior.
1244The
1245.Fl q
1246and
1247.Fl y
1248arguments can be useful for scripts.
1249.Bl -tag -width 6n
1250.It Fl q
1251Be quiet, do not print any status messages.
1252This option will not disable
1253the questions, however.
1254To disable questions, use the
1255.Fl y
1256argument, below.
1257.It Fl r
1258Run in
1259.Dq report only
1260mode.
1261This will report status on a format that is already running on the drive.
1262.It Fl w
1263Issue a non-immediate format command.
1264By default,
1265.Nm
1266issues the FORMAT UNIT command with the immediate bit set.
1267This tells the
1268device to immediately return the format command, before the format has
1269actually completed.
1270Then,
1271.Nm
1272gathers
1273.Tn SCSI

2094arguments to
2095.Fl r .
2096.It Fl c
2097Display cached attributes.
2098If the device supports this flag, it allows displaying attributes for the
2099last piece of media loaded in the drive.
2100.It Fl e Ar num
2101Specify the element address.
2102This is used for specifying which element number in a medium changer to
2103access when reading attributes.
2104The element number could be for a picker, portal, slot or drive.
2105.It Fl F Ar form1,form2
2106Specify the output format for the attribute values (attr_val) display as a
2107comma separated list of options.
2108The default output is currently set to field_all,nonascii_trim,text_raw.
2109Once this code is ported to FreeBSD 10, any text fields will be converted
2110from their codeset to the user's native codeset with
2111.Xr iconv 3 .
2112.Pp
2113The text options are mutually exclusive; if you specify more than one, you
2114will get unpredictable results.

2130print them as they are.
2131.It field_all
2132Print all of the prefix fields: description, attribute number, attribute
2133size, and the attribute's readonly status.
2134If field_all is specified, specifying any other field options will not have
2135an effect.
2136.It field_none
2137Print none of the prefix fields, and only print out the attribute value.
2138If field_none is specified, specifying any other field options will result
2139in those fields being printed.
2140.It field_desc
2141Print out the attribute description.
2142.It field_num
2143Print out the attribute number.

2151When the media has multiple partitions, specifying different partition
2152numbers allows seeing the values for each individual partition.
2153.It Fl s Ar start_num
2154Specify the starting attribute number.
2155This requests that the target device return attribute information starting
2156at the given number.
2157.It Fl T Ar elem_type
2158Specify the element type.
2159For medium changer devices, this allows specifying the type the element
2160referenced in the element address (

2179Without arguments, this command will return a list of all
2180.Tn SCSI
2181commands supported by the device, including service actions of commands
2182that support service actions.
2183It will also include the
2184.Tn SCSI

2186each command if it is known.
2187.Bl -tag -width 18n
2188.It Fl o Ar opcode
2189Request information on a specific opcode instead of the list of supported
2190commands.
2191If supported, the target will return a CDB-like structure that indicates
2192the opcode, service action (if any), and a mask of bits that are supported
2193in that CDB.
2194.It Fl s Ar service_action
2195For commands that support a service action, specify the service action to
2196query.
2197.It Fl N
2198If a service action is specified for a given opcode, and the device does
2199not support the given service action, the device should not return a
2200.Tn SCSI
2201error, but rather indicate in the returned parameter data that the command
2202is not supported.
2203By default, if a service action is specified for an opcode, and service
2204actions are not supported for the opcode in question, the device will
2205return an error.
2206.It Fl T
2207Include timeout values.
2208This option works with the default display, which includes all commands
2209supported by the device, and with the
2210.Fl o
2211and
2212.Fl s
2213options, which request information on a specific command and service
2214action.
2215This requests that the device report Nominal and Recommended timeout values
2216for the given command or commands.
2217The timeout values are in seconds.
2218The timeout descriptor also includes a command-specific

2225Zoned Block devices.
2226This allows managing devices that conform to the
2227.Tn SCSI
2228Zoned Block Commands (ZBC) and
2229.Tn ATA
2230Zoned ATA Command Set (ZAC)
2231specifications.
2232Devices using these command sets are usually hard drives using Shingled
2233Magnetic Recording (SMR).
2234There are three types of SMR drives:
2235.Bl -tag -width 13n
2236.It Drive Managed
2237Drive Managed drives look and act just like a standard random access block
2238device, but underneath, the drive reads and writes the bulk of its capacity
2239using SMR zones.
2240Sequential writes will yield better performance, but writing sequentially
2241is not required.
2242.It Host Aware
2243Host Aware drives expose the underlying zone layout via
2244.Tn SCSI
2245or
2246.Tn ATA
2247commands and allow the host to manage the zone conditions.
2248The host is not required to manage the zones on the drive, though.
2249Sequential writes will yield better performance in Sequential Write
2250Preferred zones, but the host can write randomly in those zones.
2251.It Host Managed
2252Host Managed drives expose the underlying zone layout via
2253.Tn SCSI
2254or
2255.Tn ATA
2256commands.
2257The host is required to access the zones according to the rules described
2258by the zone layout.
2259Any commands that violate the rules will be returned with an error.
2260.El
2261.Pp
2262SMR drives are divided into zones (typically in the range of 256MB each)
2263that fall into three general categories:
2264.Bl -tag -width 20n
2265.It Conventional
2266These are also known as Non Write Pointer zones.
2267These zones can be randomly written without an unexpected performance penalty.
2268.It Sequential Preferred
2269These zones should be written sequentially starting at the write pointer
2270for the zone.
2271They may be written randomly.
2272Writes that do not conform to the zone layout may be significantly slower
2273than expected.
2274.It Sequential Required
2275These zones must be written sequentially.
2276If they are not written sequentially, starting at the write pointer, the
2277command will fail.

2308.It Fl l Ar lba
2309Specify the starting LBA.
2310For the Report Zones command, this tells the drive to report starting with
2311the zone that starts at the given LBA.
2312For the other commands, this allows the user to identify the zone requested
2313by its starting LBA.
2314The LBA may be specified in decimal, hexadecimal or octal notation.

2952.Sh BUGS
2953The code that parses the generic command line arguments does not know that
2954some of the subcommands take multiple arguments.
2955So if, for instance, you
2956tried something like this:
2957.Bd -literal -offset indent
2958camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
2959.Ed
2960.Pp
2961The sense information from the test unit ready command would not get
2962printed out, since the first
2963.Xr getopt 3
2964call in
2965.Nm
2966bails out when it sees the second argument to
2967.Fl c
2968(0x00),
2969above.
2970Fixing this behavior would take some gross code, or changes to the
2971.Xr getopt 3
2972interface.
2973The best way to circumvent this problem is to always make sure
2974to specify generic
2975.Nm
2976arguments before any command-specific arguments.
2977
