377.Sh DESCRIPTION
378The
379.Nm
380utility allows users to access and control the
381.Fx
382CAM subsystem described in
383.Xr cam 4 .
384.Pp
385The
386.Nm
387utility
388can cause a loss of data and/or system crashes if used improperly.
389Even
390expert users are encouraged to exercise caution when using this command.
391Novice users should stay away from this utility.
392.Pp
393The
394.Nm
395utility has a number of primary functions, many of which support an optional
396device identifier.
397A device identifier can take one of three forms:
398.Bl -tag -width 14n
399.It deviceUNIT
400Specify a device name and unit number combination, like "da5" or "cd3".
401.It bus:target
402Specify a bus number and target id.
403The bus number can be determined from
404the output of
405.Dq camcontrol devlist .
406The lun defaults to 0.
407.It bus:target:lun
408Specify the bus, target and lun for a device.
409(e.g.\& 1:2:0)
410.El
411.Pp
412The device identifier, if it is specified,
413.Em must
414come immediately after the function name, and before any generic or
415function-specific arguments.
416Note that the
417.Fl n
418and
419.Fl u
420arguments described below will override any device name or unit number
421specified beforehand.
422The
423.Fl n
424and
425.Fl u
426arguments will
427.Em not
428override a specified bus:target or bus:target:lun, however.
429.Pp
430Most of the
431.Nm
432primary functions support these generic arguments:
433.Bl -tag -width 14n
434.It Fl C Ar count
435SCSI command retry count.
436In order for this to work, error recovery
437.Pq Fl E
438must be turned on.
439.It Fl E
440Instruct the kernel to perform generic SCSI error recovery for the given
441command.
442This is needed in order for the retry count
443.Pq Fl C
444to be honored.
445Other than retrying commands, the generic error recovery in
446the code will generally attempt to spin up drives that are not spinning.
447It may take some other actions, depending upon the sense code returned from
448the command.
449.It Fl n Ar dev_name
450Specify the device type to operate on, e.g.\& "da", "cd".
451.It Fl Q Ar task_attr
452.Tn SCSI
453task attribute for the command, if it is a
454.Tn SCSI
455command.
456This may be ordered, simple, head, or aca.
457In most cases this is not needed.
458The default is simple, which works with all
459.Tn SCSI
460devices.
461The task attribute may also be specified numerically.
462.It Fl t Ar timeout
463SCSI command timeout in seconds.
464This overrides the default timeout for
465any given command.
466.It Fl u Ar unit_number
467Specify the device unit number, e.g.\& "1", "5".
468.It Fl v
469Be verbose, print out sense information for failed SCSI commands.
470.El
471.Pp
472Primary command functions:
473.Bl -tag -width periphlist
474.It Ic devlist
475List all physical devices (logical units) attached to the CAM subsystem.
476This also includes a list of peripheral drivers attached to each device.
477With the
478.Fl v
479argument, SCSI bus number, adapter name and unit numbers are printed as
480well.
481On the other hand, with the
482.Fl b
483argument, only the bus adapter, and unit information will be printed, and
484device information will be omitted.
485.It Ic periphlist
486List all peripheral drivers attached to a given physical device (logical
487unit).
488.It Ic tur
489Send the SCSI test unit ready (0x00) command to the given device.
490The
491.Nm
492utility will report whether the device is ready or not.
493.It Ic inquiry
494Send a SCSI inquiry command (0x12) to a device.
495By default,
496.Nm
497will print out the standard inquiry data, device serial number, and
498transfer rate information.
499The user can specify that only certain types of
500inquiry data be printed:
501.Bl -tag -width 4n
502.It Fl D
503Get the standard inquiry data.
504.It Fl S
505Print out the serial number.
506If this flag is the only one specified,
507.Nm
508will not print out "Serial Number" before the value returned by the drive.
509This is to aid in script writing.
510.It Fl R
511Print out transfer rate information.
512.El
513.It Ic identify
514Send a ATA identify command (0xec) to a device.
515.It Ic reportluns
516Send the SCSI REPORT LUNS (0xA0) command to the given device.
517By default,
518.Nm
519will print out the list of logical units (LUNs) supported by the target device.
520There are a couple of options to modify the output:
521.Bl -tag -width 14n
522.It Fl c
523Just print out a count of LUNs, not the actual LUN numbers.
524.It Fl l
525Just print out the LUNs, and do not print out the count.
526.It Fl r Ar reporttype
527Specify the type of report to request from the target:
528.Bl -tag -width 012345678
529.It default
530Return the default report.
531This is the
532.Nm
533default.
534Most targets will support this report if they support the REPORT LUNS
535command.
536.It wellknown
537Return only well known LUNs.
538.It all
539Return all available LUNs.
540.El
541.El
542.Pp
543.Nm
544will try to print out LUN numbers in a reasonable format.
545It can understand the peripheral, flat, LUN and extended LUN formats.
546.It Ic readcap
547Send the SCSI READ CAPACITY command to the given device and display
548the results.
549If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
550action will be sent to obtain the full size of the device.
551By default,
552.Nm
553will print out the last logical block of the device, and the blocksize of
554the device in bytes.
555To modify the output format, use the following options:
556.Bl -tag -width 5n
557.It Fl b
558Just print out the blocksize, not the last block or device size.
559This cannot be used with
560.Fl N
561or
562.Fl s .
563.It Fl h
564Print out the device size in human readable (base 2, 1K == 1024) format.
565This implies
566.Fl N
567and cannot be used with
568.Fl q
569or
570.Fl b .
571.It Fl H
572Print out the device size in human readable (base 10, 1K == 1000) format.
573.It Fl l
574Skip sending the SCSI READ CAPACITY (10) command.
575Send only the SCSI READ CAPACITY (16) service action and report
576its results.
577When the two do not match, a quirk is needed to resolve the ambiguity.
578.It Fl N
579Print out the number of blocks in the device instead of the last logical
580block.
581.It Fl q
582Quiet, print out the numbers only (separated by a comma if
583.Fl b
584or
585.Fl s
586are not specified).
587.It Fl s
588Print out the last logical block or the size of the device only, and omit
589the blocksize.
590.El
591.Pp
592Note that this command only displays the information, it does not update
593the kernel data structures.
594Use the
595.Nm
596reprobe subcommand to do that.
597.It Ic start
598Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
599start bit set.
600.It Ic stop
601Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
602start bit cleared.
603.It Ic load
604Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
605start bit set and the load/eject bit set.
606.It Ic eject
607Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
608start bit cleared and the load/eject bit set.
609.It Ic rescan
610Tell the kernel to scan all buses in the system (with the
611.Ar all
612argument), the given bus (XPT_SCAN_BUS), bus:target:lun or device
613(XPT_SCAN_LUN) for new devices or devices that have gone away.
614The user
615may specify a scan of all buses, a single bus, or a lun.
616Scanning all luns
617on a target is not supported.
618.Pp
619If a device is specified by peripheral name and unit number, for instance
620da4, it may only be rescanned if that device currently exists in the CAM EDT
621(Existing Device Table).
622If the device is no longer there (see
623.Nm
624devlist ),
625you must use the bus:target:lun form to rescan it.
626.It Ic reprobe
627Tell the kernel to refresh the information about the device and
628notify the upper layer,
629.Xr GEOM 4 .
630This includes sending the SCSI READ CAPACITY command and updating
631the disk size visible to the rest of the system.
632.It Ic reset
633Tell the kernel to reset all buses in the system (with the
634.Ar all
635argument), the given bus (XPT_RESET_BUS) by issuing a SCSI bus
636reset for that bus, or to reset the given bus:target:lun or device
637(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
638connecting to that device.
639Note that this can have a destructive impact
640on the system.
641.It Ic defects
642Send the
643.Tn SCSI
644READ DEFECT DATA (10) command (0x37) or the
645.Tn SCSI
646READ DEFECT DATA (12) command (0xB7) to the given device, and
647print out any combination of: the total number of defects, the primary
648defect list (PLIST), and the grown defect list (GLIST).
649.Bl -tag -width 11n
650.It Fl f Ar format
651Specify the requested format of the defect list.
652The format argument is
653required.
654Most drives support the physical sector format.
655Some drives
656support the logical block format.
657Many drives, if they do not support the
658requested format, return the data in an alternate format, along with sense
659information indicating that the requested data format is not supported.
660The
661.Nm
662utility
663attempts to detect this, and print out whatever format the drive returns.
664If the drive uses a non-standard sense code to report that it does not
665support the requested format,
666.Nm
667will probably see the error as a failure to complete the request.
668.Pp
669The format options are:
670.Bl -tag -width 9n
671.It block
672Print out the list as logical blocks.
673This is limited to 32-bit block sizes, and isn't supported by many modern
674drives.
675.It longblock
676Print out the list as logical blocks.
677This option uses a 64-bit block size.
678.It bfi
679Print out the list in bytes from index format.
680.It extbfi
681Print out the list in extended bytes from index format.
682The extended format allows for ranges of blocks to be printed.
683.It phys
684Print out the list in physical sector format.
685Most drives support this format.
686.It extphys
687Print out the list in extended physical sector format.
688The extended format allows for ranges of blocks to be printed.
689.El
690.It Fl G
691Print out the grown defect list.
692This is a list of bad blocks that have
693been remapped since the disk left the factory.
694.It Fl P
695Print out the primary defect list.
696This is the list of defects that were present in the factory.
697.It Fl q
698When printing status information with
699.Fl s ,
700only print the number of defects.
701.It Fl s
702Just print the number of defects, not the list of defects.
703.It Fl S Ar offset
704Specify the starting offset into the defect list.
705This implies using the
706.Tn SCSI
707READ DEFECT DATA (12) command, as the 10 byte version of the command
708doesn't support the address descriptor index field.
709Not all drives support the 12 byte command, and some drives that support
710the 12 byte command don't support the address descriptor index field.
711.It Fl X
712Print out defects in hexadecimal (base 16) form instead of base 10 form.
713.El
714.Pp
715If neither
716.Fl P
717nor
718.Fl G
719is specified,
720.Nm
721will print out the number of defects given in the READ DEFECT DATA header
722returned from the drive.
723Some drives will report 0 defects if neither the primary or grown defect
724lists are requested.
725.It Ic modepage
726Allows the user to display and optionally edit a SCSI mode page.
727The mode
728page formats are located in
729.Pa /usr/share/misc/scsi_modes .
730This can be overridden by specifying a different file in the
731.Ev SCSI_MODES
732environment variable.
733The
734.Ic modepage
735command takes several arguments:
736.Bl -tag -width 12n
737.It Fl 6
738Use 6 byte MODE commands instead of default 10 byte.
739Old devices may not support 10 byte MODE commands, while new devices may
740not be able to report all mode pages with 6 byte commands.
741If not specified,
742.Nm
743starts with 10 byte commands and falls back to 6 byte on error.
744.It Fl d
745Disable block descriptors for mode sense.
746.It Fl D
747Display/edit block descriptors instead of mode page.
748.It Fl L
749Use long LBA block descriptors.
750Allows number of LBAs bigger then 2^^32.
751.It Fl b
752Displays mode page data in binary format.
753.It Fl e
754This flag allows the user to edit values in the mode page.
755The user may
756either edit mode page values with the text editor pointed to by his
757.Ev EDITOR
758environment variable, or supply mode page values via standard input, using
759the same format that
760.Nm
761uses to display mode page values.
762The editor will be invoked if
763.Nm
764detects that standard input is terminal.
765.It Fl l
766Lists all available mode pages.
767If specified more then once, also lists subpages.
768.It Fl m Ar page[,subpage]
769This specifies the number of the mode page and optionally subpage the user
770would like to view and/or edit.
771This argument is mandatory unless

786.El
787.El
788.It Ic cmd
789Allows the user to send an arbitrary ATA or SCSI CDB to any device.
790The
791.Ic cmd
792function requires the
793.Fl c
794argument to specify SCSI CDB or the
795.Fl a
796argument to specify ATA Command Block registers values.
797Other arguments are optional, depending on
798the command type.
799The command and data specification syntax is documented
800in
801.Xr cam_cdbparse 3 .
802NOTE: If the CDB specified causes data to be transferred to or from the
803SCSI device in question, you MUST specify either
804.Fl i
805or
806.Fl o .
807.Bl -tag -width 17n
808.It Fl a Ar cmd Op args
809This specifies the content of 12 ATA Command Block registers (command,
810features, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp.
811lba_high_exp, features_exp, sector_count, sector_count_exp).
812.It Fl c Ar cmd Op args

830.Ar len
831bytes of data will be read from standard input and written to the device.
832.It Fl r Ar fmt
833This specifies that 11 result ATA Command Block registers should be displayed
834(status, error, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp,
835lba_high_exp, sector_count, sector_count_exp), and how.
836If the format is
837.Sq - ,
83811 result registers will be written to standard output in hex.
839.El
840.It Ic smpcmd
841Allows the user to send an arbitrary Serial
842Management Protocol (SMP) command to a device.
843The
844.Ic smpcmd
845function requires the
846.Fl r
847argument to specify the SMP request to be sent, and the
848.Fl R
849argument to specify the format of the SMP response.
850The syntax for the SMP request and response arguments is documented in
851.Xr cam_cdbparse 3 .
852.Pp
853Note that SAS adapters that support SMP passthrough (at least the currently
854known adapters) do not accept CRC bytes from the user in the request and do
855not pass CRC bytes back to the user in the response.
856Therefore users should not include the CRC bytes in the length of the
857request and not expect CRC bytes to be returned in the response.
858.Bl -tag -width 17n
859.It Fl r Ar len Ar fmt Op args
860This specifies the size of the SMP request, without the CRC bytes, and the
861SMP request format.
862If the format is
863.Sq - ,
864.Ar len
865bytes of data will be read from standard input and written as the SMP
866request.
867.It Fl R Ar len Ar fmt Op args
868This specifies the size of the buffer allocated for the SMP response, and
869the SMP response format.
870If the format is
871.Sq - ,
872.Ar len
873bytes of data will be allocated for the response and the response will be
874written to standard output.
875.El
876.It Ic smprg
877Allows the user to send the Serial Management Protocol (SMP) Report General
878command to a device.
879.Nm
880will display the data returned by the Report General command.
881If the SMP target supports the long response format, the additional data
882will be requested and displayed automatically.
883.Bl -tag -width 8n
884.It Fl l
885Request the long response format only.
886Not all SMP targets support the long response format.
887This option causes
888.Nm
889to skip sending the initial report general request without the long bit set
890and only issue a report general request with the long bit set.
891.El
892.It Ic smppc
893Allows the user to issue the Serial Management Protocol (SMP) PHY Control
894command to a device.
895This function should be used with some caution, as it can render devices
896inaccessible, and could potentially cause data corruption as well.
897The
898.Fl p
899argument is required to specify the PHY to operate on.
900.Bl -tag -width 17n
901.It Fl p Ar phy
902Specify the PHY to operate on.
903This argument is required.
904.It Fl l
905Request the long request/response format.
906Not all SMP targets support the long response format.
907For the PHY Control command, this currently only affects whether the
908request length is set to a value other than 0.
909.It Fl o Ar operation
910Specify a PHY control operation.
911Only one
912.Fl o
913operation may be specified.
914The operation may be specified numerically (in decimal, hexadecimal, or octal)
915or one of the following operation names may be specified:
916.Bl -tag -width 16n
917.It nop
918No operation.
919It is not necessary to specify this argument.

929This clears the error log counters for the specified phy.
930.It clearaffiliation
931Send the CLEAR AFFILIATION command.
932This clears the affiliation from the STP initiator port with the same SAS
933address as the SMP initiator that requests the clear operation.
934.It sataportsel
935Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
936This will cause a SATA port selector to use the given phy as its active phy
937and make the other phy inactive.
938.It clearitnl
939Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
940.It setdevname
941Send the SET ATTACHED DEVICE NAME command to the PHY.
942This requires the
943.Fl d
944argument to specify the device name.
945.El
946.It Fl d Ar name
947Specify the attached device name.
948This option is needed with the

1011.El
1012.It Ic debug
1013Turn on CAM debugging printfs in the kernel.
1014This requires options CAMDEBUG
1015in your kernel config file.
1016WARNING: enabling debugging printfs currently
1017causes an EXTREME number of kernel printfs.
1018You may have difficulty
1019turning off the debugging printfs once they start, since the kernel will be
1020busy printing messages and unable to service other requests quickly.
1021The
1022.Ic debug
1023function takes a number of arguments:
1024.Bl -tag -width 18n
1025.It Fl I
1026Enable CAM_DEBUG_INFO printfs.

1040Enable CAM_DEBUG_PROBE printfs.
1041.It all
1042Enable debugging for all devices.
1043.It off
1044Turn off debugging for all devices
1045.It bus Ns Op :target Ns Op :lun
1046Turn on debugging for the given bus, target or lun.
1047If the lun or target
1048and lun are not specified, they are wildcarded.
1049(i.e., just specifying a
1050bus turns on debugging printfs for all devices on that bus.)
1051.El
1052.It Ic tags
1053Show or set the number of "tagged openings" or simultaneous transactions
1054we attempt to queue to a particular device.
1055By default, the
1056.Ic tags
1057command, with no command-specific arguments (i.e., only generic arguments)
1058prints out the "soft" maximum number of transactions that can be queued to
1059the device in question.
1060For more detailed information, use the
1061.Fl v
1062argument described below.
1063.Bl -tag -width 7n
1064.It Fl N Ar tags
1065Set the number of tags for the given device.
1066This must be between the
1067minimum and maximum number set in the kernel quirk table.
1068The default for
1069most devices that support tagged queueing is a minimum of 2 and a maximum
1070of 255.
1071The minimum and maximum values for a given device may be
1072determined by using the
1073.Fl v
1074switch.
1075The meaning of the
1076.Fl v
1077switch for this
1078.Nm
1079subcommand is described below.
1080.It Fl q
1081Be quiet, and do not report the number of tags.
1082This is generally used when
1083setting the number of tags.
1084.It Fl v
1085The verbose flag has special functionality for the
1086.Em tags
1087argument.
1088It causes
1089.Nm
1090to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
1091.Bl -tag -width 13n
1092.It dev_openings
1093This is the amount of capacity for transactions queued to a given device.
1094.It dev_active
1095This is the number of transactions currently queued to a device.
1096.It allocated
1097This is the number of CCBs allocated for the device.
1098.It held
1099The held count is the number of CCBs held by peripheral drivers that have
1100either just been completed or are about to be released to the transport
1101layer for service by a device.
1102Held CCBs reserve capacity on a given
1103device.
1104.It mintags
1105This is the current "hard" minimum number of transactions that can be
1106queued to a device at once.
1107The
1108.Ar dev_openings
1109value above cannot go below this number.
1110The default value for
1111.Ar mintags
1112is 2, although it may be set higher or lower for various devices.
1113.It maxtags
1114This is the "hard" maximum number of transactions that can be queued to a
1115device at one time.
1116The
1117.Ar dev_openings
1118value cannot go above this number.
1119The default value for
1120.Ar maxtags
1121is 255, although it may be set higher or lower for various devices.
1122.El
1123.El
1124.It Ic negotiate
1125Show or negotiate various communication parameters.
1126Some controllers may
1127not support setting or changing some of these values.
1128For instance, the
1129Adaptec 174x controllers do not support changing a device's sync rate or
1130offset.
1131The
1132.Nm
1133utility
1134will not attempt to set the parameter if the controller indicates that it
1135does not support setting the parameter.
1136To find out what the controller
1137supports, use the
1138.Fl v
1139flag.
1140The meaning of the
1141.Fl v
1142flag for the
1143.Ic negotiate
1144command is described below.
1145Also, some controller drivers do not support
1146setting negotiation parameters, even if the underlying controller supports
1147negotiation changes.
1148Some controllers, such as the Advansys wide
1149controllers, support enabling and disabling synchronous negotiation for
1150a device, but do not support setting the synchronous negotiation rate.
1151.Bl -tag -width 17n
1152.It Fl a
1153Attempt to make the negotiation settings take effect immediately by sending
1154a Test Unit Ready command to the device.
1155.It Fl c
1156Show or set current negotiation settings.
1157This is the default.
1158.It Fl D Ar enable|disable
1159Enable or disable disconnection.
1160.It Fl M Ar mode
1161Set ATA mode.
1162.It Fl O Ar offset
1163Set the command delay offset.
1164.It Fl q
1165Be quiet, do not print anything.
1166This is generally useful when you want to
1167set a parameter, but do not want any status information.
1168.It Fl R Ar syncrate
1169Change the synchronization rate for a device.
1170The sync rate is a floating
1171point value specified in MHz.
1172So, for instance,
1173.Sq 20.000
1174is a legal value, as is
1175.Sq 20 .
1176.It Fl T Ar enable|disable
1177Enable or disable tagged queueing for a device.
1178.It Fl U
1179Show or set user negotiation settings.
1180The default is to show or set
1181current negotiation settings.
1182.It Fl v
1183The verbose switch has special meaning for the
1184.Ic negotiate
1185subcommand.
1186It causes
1187.Nm
1188to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the
1189controller driver.
1190.It Fl W Ar bus_width
1191Specify the bus width to negotiate with a device.
1192The bus width is
1193specified in bits.
1194The only useful values to specify are 8, 16, and 32
1195bits.
1196The controller must support the bus width in question in order for
1197the setting to take effect.
1198.El
1199.Pp
1200In general, sync rate and offset settings will not take effect for a
1201device until a command has been sent to the device.
1202The
1203.Fl a
1204switch above will automatically send a Test Unit Ready to the device so
1205negotiation parameters will take effect.
1206.It Ic format
1207Issue the
1208.Tn SCSI
1209FORMAT UNIT command to the named device.
1210.Pp
1211.Em WARNING! WARNING! WARNING!
1212.Pp
1213Low level formatting a disk will destroy ALL data on the disk.
1214Use
1215extreme caution when issuing this command.
1216Many users low-level format
1217disks that do not really need to be low-level formatted.
1218There are
1219relatively few scenarios that call for low-level formatting a disk.
1220One reason for
1221low-level formatting a disk is to initialize the disk after changing
1222its physical sector size.
1223Another reason for low-level formatting a disk
1224is to revive the disk if you are getting "medium format corrupted" errors
1225from the disk in response to read and write requests.
1226.Pp
1227Some disks take longer than others to format.
1228Users should specify a
1229timeout long enough to allow the format to complete.
1230The default format
1231timeout is 3 hours, which should be long enough for most disks.
1232Some hard
1233disks will complete a format operation in a very short period of time
1234(on the order of 5 minutes or less).
1235This is often because the drive
1236does not really support the FORMAT UNIT command -- it just accepts the
1237command, waits a few minutes and then returns it.
1238.Pp
1239The
1240.Sq format
1241subcommand takes several arguments that modify its default behavior.
1242The
1243.Fl q
1244and
1245.Fl y
1246arguments can be useful for scripts.
1247.Bl -tag -width 6n
1248.It Fl q
1249Be quiet, do not print any status messages.
1250This option will not disable
1251the questions, however.
1252To disable questions, use the
1253.Fl y
1254argument, below.
1255.It Fl r
1256Run in
1257.Dq report only
1258mode.
1259This will report status on a format that is already running on the drive.
1260.It Fl w
1261Issue a non-immediate format command.
1262By default,
1263.Nm
1264issues the FORMAT UNIT command with the immediate bit set.
1265This tells the
1266device to immediately return the format command, before the format has
1267actually completed.
1268Then,
1269.Nm
1270gathers
1271.Tn SCSI
1272sense information from the device every second to determine how far along
1273in the format process it is.
1274If the
1275.Fl w
1276argument is specified,
1277.Nm
1278will issue a non-immediate format command, and will be unable to print any

2096If the device supports this flag, it allows displaying attributes for the
2097last piece of media loaded in the drive.
2098.It Fl e Ar num
2099Specify the element address.
2100This is used for specifying which element number in a medium changer to
2101access when reading attributes.
2102The element number could be for a picker, portal, slot or drive.
2103.It Fl F Ar form1,form2
2104Specify the output format for the attribute values (attr_val) display as a

2128print them as they are.
2129.It field_all
2130Print all of the prefix fields: description, attribute number, attribute
2131size, and the attribute's readonly status.
2132If field_all is specified, specifying any other field options will not have
2133an effect.
2134.It field_none
2135Print none of the prefix fields, and only print out the attribute value.
2136If field_none is specified, specifying any other field options will result

2185.Bl -tag -width 18n
2186.It Fl o Ar opcode
2187Request information on a specific opcode instead of the list of supported
2188commands.
2189If supported, the target will return a CDB-like structure that indicates
2190the opcode, service action (if any), and a mask of bits that are supported
2191in that CDB.
2192.It Fl s Ar service_action
2193For commands that support a service action, specify the service action to
2194query.
2195.It Fl N
2196If a service action is specified for a given opcode, and the device does
2197not support the given service action, the device should not return a
2198.Tn SCSI
2199error, but rather indicate in the returned parameter data that the command
2200is not supported.
2201By default, if a service action is specified for an opcode, and service
2202actions are not supported for the opcode in question, the device will
2203return an error.
2204.It Fl T
2205Include timeout values.
2206This option works with the default display, which includes all commands
2207supported by the device, and with the
2208.Fl o
2209and
2210.Fl s
2211options, which request information on a specific command and service
2212action.
2213This requests that the device report Nominal and Recommended timeout values
2214for the given command or commands.
2215The timeout values are in seconds.
2216The timeout descriptor also includes a command-specific

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

2307For the Report Zones command, this tells the drive to report starting with
2308the zone that starts at the given LBA.
2309For the other commands, this allows the user to identify the zone requested
2310by its starting LBA.
2311The LBA may be specified in decimal, hexadecimal or octal notation.

3000.Sh BUGS
3001The code that parses the generic command line arguments does not know that
3002some of the subcommands take multiple arguments.
3003So if, for instance, you
3004tried something like this:
3005.Bd -literal -offset indent
3006camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
3007.Ed
3008.Pp
3009The sense information from the test unit ready command would not get
3010printed out, since the first
3011.Xr getopt 3
3012call in
3013.Nm
3014bails out when it sees the second argument to
3015.Fl c
3016(0x00),
3017above.
3018Fixing this behavior would take some gross code, or changes to the
3019.Xr getopt 3
3020interface.
3021The best way to circumvent this problem is to always make sure
