352.Sh DESCRIPTION
353The
354.Nm
355utility is designed to provide a way for users to access and control the
356.Fx
357CAM subsystem.
358.Pp
359The
360.Nm
361utility
362can cause a loss of data and/or system crashes if used improperly.
363Even
364expert users are encouraged to exercise caution when using this command.
365Novice users should stay away from this utility.
366.Pp
367The
368.Nm
369utility has a number of primary functions, many of which support an optional
370device identifier.
371A device identifier can take one of three forms:
372.Bl -tag -width 14n
373.It deviceUNIT
374Specify a device name and unit number combination, like "da5" or "cd3".
375.It bus:target
376Specify a bus number and target id.
377The bus number can be determined from
378the output of
379.Dq camcontrol devlist .
380The lun defaults to 0.
381.It bus:target:lun
382Specify the bus, target and lun for a device.
383(e.g.\& 1:2:0)
384.El
385.Pp
386The device identifier, if it is specified,
387.Em must
388come immediately after the function name, and before any generic or
389function-specific arguments.
390Note that the
391.Fl n
392and
393.Fl u
394arguments described below will override any device name or unit number
395specified beforehand.
396The
397.Fl n
398and
399.Fl u
400arguments will
401.Em not
402override a specified bus:target or bus:target:lun, however.
403.Pp
404Most of the
405.Nm
406primary functions support these generic arguments:
407.Bl -tag -width 14n
408.It Fl C Ar count
409SCSI command retry count.
410In order for this to work, error recovery
411.Pq Fl E
412must be turned on.
413.It Fl E
414Instruct the kernel to perform generic SCSI error recovery for the given
415command.
416This is needed in order for the retry count
417.Pq Fl C
418to be honored.
419Other than retrying commands, the generic error recovery in
420the code will generally attempt to spin up drives that are not spinning.
421It may take some other actions, depending upon the sense code returned from
422the command.
423.It Fl n Ar dev_name
424Specify the device type to operate on, e.g.\& "da", "cd".
425.It Fl Q Ar task_attr
426.Tn SCSI
427task attribute for the command, if it is a
428.Tn SCSI
429command.
430This may be ordered, simple, head, or aca.
431In most cases this is not needed.
432The default is simple, which works with all
433.Tn SCSI
434devices.
435The task attribute may also be specified numerically.
436.It Fl t Ar timeout
437SCSI command timeout in seconds.
438This overrides the default timeout for
439any given command.
440.It Fl u Ar unit_number
441Specify the device unit number, e.g.\& "1", "5".
442.It Fl v
443Be verbose, print out sense information for failed SCSI commands.
444.El
445.Pp
446Primary command functions:
447.Bl -tag -width periphlist
448.It Ic devlist
449List all physical devices (logical units) attached to the CAM subsystem.
450This also includes a list of peripheral drivers attached to each device.
451With the
452.Fl v
453argument, SCSI bus number, adapter name and unit numbers are printed as
454well.
455On the other hand, with the
456.Fl b
457argument, only the bus adapter, and unit information will be printed, and
458device information will be omitted.
459.It Ic periphlist
460List all peripheral drivers attached to a given physical device (logical
461unit).
462.It Ic tur
463Send the SCSI test unit ready (0x00) command to the given device.
464The
465.Nm
466utility will report whether the device is ready or not.
467.It Ic inquiry
468Send a SCSI inquiry command (0x12) to a device.
469By default,
470.Nm
471will print out the standard inquiry data, device serial number, and
472transfer rate information.
473The user can specify that only certain types of
474inquiry data be printed:
475.Bl -tag -width 4n
476.It Fl D
477Get the standard inquiry data.
478.It Fl S
479Print out the serial number.
480If this flag is the only one specified,
481.Nm
482will not print out "Serial Number" before the value returned by the drive.
483This is to aid in script writing.
484.It Fl R
485Print out transfer rate information.
486.El
487.It Ic identify
488Send a ATA identify command (0xec) to a device.
489.It Ic reportluns
490Send the SCSI REPORT LUNS (0xA0) command to the given device.
491By default,
492.Nm
493will print out the list of logical units (LUNs) supported by the target device.
494There are a couple of options to modify the output:
495.Bl -tag -width 14n
496.It Fl c
497Just print out a count of LUNs, not the actual LUN numbers.
498.It Fl l
499Just print out the LUNs, and do not print out the count.
500.It Fl r Ar reporttype
501Specify the type of report to request from the target:
502.Bl -tag -width 012345678
503.It default
504Return the default report.
505This is the
506.Nm
507default.
508Most targets will support this report if they support the REPORT LUNS
509command.
510.It wellknown
511Return only well known LUNs.
512.It all
513Return all available LUNs.
514.El
515.El
516.Pp
517.Nm
518will try to print out LUN numbers in a reasonable format.
519It can understand the peripheral, flat, LUN and extended LUN formats.
520.It Ic readcap
521Send the SCSI READ CAPACITY command to the given device and display
522the results.
523If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
524action will be sent to obtain the full size of the device.
525By default,
526.Nm
527will print out the last logical block of the device, and the blocksize of
528the device in bytes.
529To modify the output format, use the following options:
530.Bl -tag -width 5n
531.It Fl b
532Just print out the blocksize, not the last block or device size.
533This cannot be used with
534.Fl N
535or
536.Fl s .
537.It Fl h
538Print out the device size in human readable (base 2, 1K == 1024) format.
539This implies
540.Fl N
541and cannot be used with
542.Fl q
543or
544.Fl b .
545.It Fl H
546Print out the device size in human readable (base 10, 1K == 1000) format.
547.It Fl N
548Print out the number of blocks in the device instead of the last logical
549block.
550.It Fl q
551Quiet, print out the numbers only (separated by a comma if
552.Fl b
553or
554.Fl s
555are not specified).
556.It Fl s
557Print out the last logical block or the size of the device only, and omit
558the blocksize.
559.El
560.Pp
561Note that this command only displays the information, it does not update
562the kernel data structures.
563Use the
564.Nm
565reprobe subcommand to do that.
566.It Ic start
567Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
568start bit set.
569.It Ic stop
570Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
571start bit cleared.
572.It Ic load
573Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
574start bit set and the load/eject bit set.
575.It Ic eject
576Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
577start bit cleared and the load/eject bit set.
578.It Ic rescan
579Tell the kernel to scan all buses in the system (with the
580.Ar all
581argument), the given bus (XPT_SCAN_BUS), bus:target:lun or device
582(XPT_SCAN_LUN) for new devices or devices that have gone away.
583The user
584may specify a scan of all buses, a single bus, or a lun.
585Scanning all luns
586on a target is not supported.
587.Pp
588If a device is specified by peripheral name and unit number, for instance
589da4, it may only be rescanned if that device currently exists in the CAM EDT
590(Existing Device Table).
591If the device is no longer there (see
592.Nm
593devlist ),
594you must use the bus:target:lun form to rescan it.
595.It Ic reprobe
596Tell the kernel to refresh the information about the device and
597notify the upper layer,
598.Xr GEOM 4 .
599This includes sending the SCSI READ CAPACITY command and updating
600the disk size visible to the rest of the system.
601.It Ic reset
602Tell the kernel to reset all buses in the system (with the
603.Ar all
604argument), the given bus (XPT_RESET_BUS) by issuing a SCSI bus
605reset for that bus, or to reset the given bus:target:lun or device
606(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
607connecting to that device.
608Note that this can have a destructive impact
609on the system.
610.It Ic defects
611Send the
612.Tn SCSI
613READ DEFECT DATA (10) command (0x37) or the
614.Tn SCSI
615READ DEFECT DATA (12) command (0xB7) to the given device, and
616print out any combination of: the total number of defects, the primary
617defect list (PLIST), and the grown defect list (GLIST).
618.Bl -tag -width 11n
619.It Fl f Ar format
620Specify the requested format of the defect list.
621The format argument is
622required.
623Most drives support the physical sector format.
624Some drives
625support the logical block format.
626Many drives, if they do not support the
627requested format, return the data in an alternate format, along with sense
628information indicating that the requested data format is not supported.
629The
630.Nm
631utility
632attempts to detect this, and print out whatever format the drive returns.
633If the drive uses a non-standard sense code to report that it does not
634support the requested format,
635.Nm
636will probably see the error as a failure to complete the request.
637.Pp
638The format options are:
639.Bl -tag -width 9n
640.It block
641Print out the list as logical blocks.
642This is limited to 32-bit block sizes, and isn't supported by many modern
643drives.
644.It longblock
645Print out the list as logical blocks.
646This option uses a 64-bit block size.
647.It bfi
648Print out the list in bytes from index format.
649.It extbfi
650Print out the list in extended bytes from index format.
651The extended format allows for ranges of blocks to be printed.
652.It phys
653Print out the list in physical sector format.
654Most drives support this format.
655.It extphys
656Print out the list in extended physical sector format.
657The extended format allows for ranges of blocks to be printed.
658.El
659.It Fl G
660Print out the grown defect list.
661This is a list of bad blocks that have
662been remapped since the disk left the factory.
663.It Fl P
664Print out the primary defect list.
665This is the list of defects that were present in the factory.
666.It Fl q
667When printing status information with
668.Fl s ,
669only print the number of defects.
670.It Fl s
671Just print the number of defects, not the list of defects.
672.It Fl S Ar offset
673Specify the starting offset into the defect list.
674This implies using the
675.Tn SCSI
676READ DEFECT DATA (12) command, as the 10 byte version of the command
677doesn't support the address descriptor index field.
678Not all drives support the 12 byte command, and some drives that support
679the 12 byte command don't support the address descriptor index field.
680.It Fl X
681Print out defects in hexadecimal (base 16) form instead of base 10 form.
682.El
683.Pp
684If neither

687.Fl G
688is specified,
689.Nm
690will print out the number of defects given in the READ DEFECT DATA header
691returned from the drive.
692Some drives will report 0 defects if neither the primary or grown defect
693lists are requested.
694.It Ic modepage
695Allows the user to display and optionally edit a SCSI mode page.
696The mode
697page formats are located in
698.Pa /usr/share/misc/scsi_modes .
699This can be overridden by specifying a different file in the
700.Ev SCSI_MODES
701environment variable.
702The
703.Ic modepage
704command takes several arguments:
705.Bl -tag -width 12n
706.It Fl d
707Disable block descriptors for mode sense.
708.It Fl b
709Displays mode page data in binary format.
710.It Fl e
711This flag allows the user to edit values in the mode page.
712The user may
713either edit mode page values with the text editor pointed to by his
714.Ev EDITOR
715environment variable, or supply mode page values via standard input, using
716the same format that
717.Nm
718uses to display mode page values.
719The editor will be invoked if
720.Nm
721detects that standard input is terminal.
722.It Fl l
723Lists all available mode pages.
724If specified more then once, also lists subpages.
725.It Fl m Ar page[,subpage]
726This specifies the number of the mode page and optionally subpage the user
727would like to view and/or edit.
728This argument is mandatory unless

744.El
745.It Ic cmd
746Allows the user to send an arbitrary ATA or SCSI CDB to any device.
747The
748.Ic cmd
749function requires the
750.Fl c
751argument to specify SCSI CDB or the
752.Fl a
753argument to specify ATA Command Block registers values.
754Other arguments are optional, depending on
755the command type.
756The command and data specification syntax is documented
757in
758.Xr cam_cdbparse 3 .
759NOTE: If the CDB specified causes data to be transferred to or from the

79511 result registers will be written to standard output in hex.
796.El
797.It Ic smpcmd
798Allows the user to send an arbitrary Serial
799Management Protocol (SMP) command to a device.
800The
801.Ic smpcmd
802function requires the
803.Fl r
804argument to specify the SMP request to be sent, and the
805.Fl R
806argument to specify the format of the SMP response.
807The syntax for the SMP request and response arguments is documented in
808.Xr cam_cdbparse 3 .
809.Pp
810Note that SAS adapters that support SMP passthrough (at least the currently
811known adapters) do not accept CRC bytes from the user in the request and do
812not pass CRC bytes back to the user in the response.
813Therefore users should not include the CRC bytes in the length of the
814request and not expect CRC bytes to be returned in the response.
815.Bl -tag -width 17n
816.It Fl r Ar len Ar fmt Op args
817This specifies the size of the SMP request, without the CRC bytes, and the

821.Ar len
822bytes of data will be read from standard input and written as the SMP
823request.
824.It Fl R Ar len Ar fmt Op args
825This specifies the size of the buffer allocated for the SMP response, and
826the SMP response format.
827If the format is
828.Sq - ,
829.Ar len
830bytes of data will be allocated for the response and the response will be
831written to standard output.
832.El
833.It Ic smprg
834Allows the user to send the Serial Management Protocol (SMP) Report General
835command to a device.
836.Nm
837will display the data returned by the Report General command.
838If the SMP target supports the long response format, the additional data
839will be requested and displayed automatically.
840.Bl -tag -width 8n
841.It Fl l
842Request the long response format only.
843Not all SMP targets support the long response format.
844This option causes
845.Nm
846to skip sending the initial report general request without the long bit set
847and only issue a report general request with the long bit set.
848.El
849.It Ic smppc
850Allows the user to issue the Serial Management Protocol (SMP) PHY Control
851command to a device.
852This function should be used with some caution, as it can render devices
853inaccessible, and could potentially cause data corruption as well.
854The
855.Fl p
856argument is required to specify the PHY to operate on.
857.Bl -tag -width 17n
858.It Fl p Ar phy
859Specify the PHY to operate on.
860This argument is required.
861.It Fl l
862Request the long request/response format.
863Not all SMP targets support the long response format.
864For the PHY Control command, this currently only affects whether the
865request length is set to a value other than 0.
866.It Fl o Ar operation
867Specify a PHY control operation.
868Only one
869.Fl o
870operation may be specified.

878Send the LINK RESET command to the phy.
879.It hardreset
880Send the HARD RESET command to the phy.
881.It disable
882Send the DISABLE command to the phy.
883Note that the LINK RESET or HARD RESET commands should re-enable the phy.
884.It clearerrlog
885Send the CLEAR ERROR LOG command.
886This clears the error log counters for the specified phy.
887.It clearaffiliation
888Send the CLEAR AFFILIATION command.
889This clears the affiliation from the STP initiator port with the same SAS
890address as the SMP initiator that requests the clear operation.
891.It sataportsel
892Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
893This will cause a SATA port selector to use the given phy as its active phy
894and make the other phy inactive.
895.It clearitnl
896Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
897.It setdevname
898Send the SET ATTACHED DEVICE NAME command to the PHY.
899This requires the

969.It Ic debug
970Turn on CAM debugging printfs in the kernel.
971This requires options CAMDEBUG
972in your kernel config file.
973WARNING: enabling debugging printfs currently
974causes an EXTREME number of kernel printfs.
975You may have difficulty
976turning off the debugging printfs once they start, since the kernel will be
977busy printing messages and unable to service other requests quickly.
978The
979.Ic debug
980function takes a number of arguments:
981.Bl -tag -width 18n
982.It Fl I
983Enable CAM_DEBUG_INFO printfs.

1002.It bus Ns Op :target Ns Op :lun
1003Turn on debugging for the given bus, target or lun.
1004If the lun or target
1005and lun are not specified, they are wildcarded.
1006(i.e., just specifying a
1007bus turns on debugging printfs for all devices on that bus.)
1008.El
1009.It Ic tags
1010Show or set the number of "tagged openings" or simultaneous transactions
1011we attempt to queue to a particular device.
1012By default, the
1013.Ic tags
1014command, with no command-specific arguments (i.e., only generic arguments)
1015prints out the "soft" maximum number of transactions that can be queued to
1016the device in question.
1017For more detailed information, use the
1018.Fl v
1019argument described below.
1020.Bl -tag -width 7n
1021.It Fl N Ar tags
1022Set the number of tags for the given device.
1023This must be between the
1024minimum and maximum number set in the kernel quirk table.
1025The default for
1026most devices that support tagged queueing is a minimum of 2 and a maximum
1027of 255.
1028The minimum and maximum values for a given device may be
1029determined by using the
1030.Fl v
1031switch.
1032The meaning of the
1033.Fl v
1034switch for this
1035.Nm
1036subcommand is described below.
1037.It Fl q
1038Be quiet, and do not report the number of tags.
1039This is generally used when
1040setting the number of tags.
1041.It Fl v
1042The verbose flag has special functionality for the
1043.Em tags
1044argument.
1045It causes
1046.Nm
1047to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
1048.Bl -tag -width 13n
1049.It dev_openings
1050This is the amount of capacity for transactions queued to a given device.
1051.It dev_active
1052This is the number of transactions currently queued to a device.
1053.It devq_openings
1054This is the kernel queue space for transactions.
1055This count usually mirrors
1056dev_openings except during error recovery operations when
1057the device queue is frozen (device is not allowed to receive
1058commands), the number of dev_openings is reduced, or transaction
1059replay is occurring.
1060.It devq_queued
1061This is the number of transactions waiting in the kernel queue for capacity
1062on the device.
1063This number is usually zero unless error recovery is in
1064progress.
1065.It held
1066The held count is the number of CCBs held by peripheral drivers that have
1067either just been completed or are about to be released to the transport
1068layer for service by a device.
1069Held CCBs reserve capacity on a given
1070device.
1071.It mintags
1072This is the current "hard" minimum number of transactions that can be
1073queued to a device at once.
1074The
1075.Ar dev_openings
1076value above cannot go below this number.
1077The default value for
1078.Ar mintags
1079is 2, although it may be set higher or lower for various devices.
1080.It maxtags
1081This is the "hard" maximum number of transactions that can be queued to a
1082device at one time.
1083The
1084.Ar dev_openings
1085value cannot go above this number.
1086The default value for
1087.Ar maxtags
1088is 255, although it may be set higher or lower for various devices.
1089.El
1090.El
1091.It Ic negotiate
1092Show or negotiate various communication parameters.
1093Some controllers may
1094not support setting or changing some of these values.
1095For instance, the
1096Adaptec 174x controllers do not support changing a device's sync rate or
1097offset.
1098The
1099.Nm
1100utility
1101will not attempt to set the parameter if the controller indicates that it
1102does not support setting the parameter.
1103To find out what the controller
1104supports, use the
1105.Fl v
1106flag.
1107The meaning of the
1108.Fl v
1109flag for the
1110.Ic negotiate
1111command is described below.
1112Also, some controller drivers do not support
1113setting negotiation parameters, even if the underlying controller supports
1114negotiation changes.
1115Some controllers, such as the Advansys wide
1116controllers, support enabling and disabling synchronous negotiation for
1117a device, but do not support setting the synchronous negotiation rate.
1118.Bl -tag -width 17n
1119.It Fl a
1120Attempt to make the negotiation settings take effect immediately by sending
1121a Test Unit Ready command to the device.

1124This is the default.
1125.It Fl D Ar enable|disable
1126Enable or disable disconnection.
1127.It Fl M Ar mode
1128Set ATA mode.
1129.It Fl O Ar offset
1130Set the command delay offset.
1131.It Fl q
1132Be quiet, do not print anything.
1133This is generally useful when you want to
1134set a parameter, but do not want any status information.
1135.It Fl R Ar syncrate
1136Change the synchronization rate for a device.
1137The sync rate is a floating
1138point value specified in MHz.
1139So, for instance,
1140.Sq 20.000
1141is a legal value, as is
1142.Sq 20 .
1143.It Fl T Ar enable|disable
1144Enable or disable tagged queueing for a device.
1145.It Fl U
1146Show or set user negotiation settings.
1147The default is to show or set
1148current negotiation settings.
1149.It Fl v
1150The verbose switch has special meaning for the
1151.Ic negotiate
1152subcommand.
1153It causes
1154.Nm
1155to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the
1156controller driver.
1157.It Fl W Ar bus_width
1158Specify the bus width to negotiate with a device.
1159The bus width is
1160specified in bits.
1161The only useful values to specify are 8, 16, and 32
1162bits.
1163The controller must support the bus width in question in order for
1164the setting to take effect.
1165.El
1166.Pp
1167In general, sync rate and offset settings will not take effect for a
1168device until a command has been sent to the device.
1169The
1170.Fl a
1171switch above will automatically send a Test Unit Ready to the device so
1172negotiation parameters will take effect.
1173.It Ic format

1179.Pp
1180Low level formatting a disk will destroy ALL data on the disk.
1181Use
1182extreme caution when issuing this command.
1183Many users low-level format
1184disks that do not really need to be low-level formatted.
1185There are
1186relatively few scenarios that call for low-level formatting a disk.
1187One reason for
1188low-level formatting a disk is to initialize the disk after changing
1189its physical sector size.
1190Another reason for low-level formatting a disk
1191is to revive the disk if you are getting "medium format corrupted" errors
1192from the disk in response to read and write requests.
1193.Pp
1194Some disks take longer than others to format.
1195Users should specify a
1196timeout long enough to allow the format to complete.
1197The default format
1198timeout is 3 hours, which should be long enough for most disks.
1199Some hard
1200disks will complete a format operation in a very short period of time
1201(on the order of 5 minutes or less).
1202This is often because the drive
1203does not really support the FORMAT UNIT command -- it just accepts the
1204command, waits a few minutes and then returns it.
1205.Pp
1206The
1207.Sq format
1208subcommand takes several arguments that modify its default behavior.
1209The
1210.Fl q
1211and
1212.Fl y
1213arguments can be useful for scripts.
1214.Bl -tag -width 6n
1215.It Fl q

1217This option will not disable
1218the questions, however.

1220.Fl y
1221argument, below.
1222.It Fl r
1223Run in
1224.Dq report only
1225mode.
1226This will report status on a format that is already running on the drive.
1227.It Fl w
1228Issue a non-immediate format command.
1229By default,
1230.Nm
1231issues the FORMAT UNIT command with the immediate bit set.
1232This tells the
1233device to immediately return the format command, before the format has
1234actually completed.
1235Then,
1236.Nm
1237gathers
1238.Tn SCSI
1239sense information from the device every second to determine how far along
1240in the format process it is.
1241If the
1242.Fl w
1243argument is specified,
1244.Nm
1245will issue a non-immediate format command, and will be unable to print any
1246information to let the user know what percentage of the disk has been
1247formatted.
1248.It Fl y
1249Do not ask any questions.
1250By default,
1251.Nm
1252will ask the user if he/she really wants to format the disk in question,
1253and also if the default format command timeout is acceptable.
1254The user
1255will not be asked about the timeout if a timeout is specified on the
1256command line.

1878followed by a PCIe Routing ID.
1879The Routing ID consists of a bus, device and function or in the alternate
1880form, a bus and function.
1881The bus must be in the range of 0 to 255 inclusive and the device must be
1882in the range of 0 to 31 inclusive.
1883The function must be in the range of 0 to 7 inclusive if the standard form
1884is used, and in the range of 0 to 255 inclusive if the alternate form is
1885used.
1886For example, if a bus, device and function are specified for the standard
1887Routing ID form:
1888.Pp
1889.Dl sop,4,5,1
1890.Pp
1891If the alternate Routing ID form is used:
1892.Pp
1893.Dl sop,4,1

1981.El
1982.It Ic attrib
1983Issue the
1984.Tn SCSI
1985READ or WRITE ATTRIBUTE commands.
1986These commands are used to read and write attributes in Medium Auxiliary
1987Memory (MAM).
1988The most common place Medium Auxiliary Memory is found is small flash chips
1989included tape cartriges.
1990For instance,
1991.Tn LTO
1992tapes have MAM.
1993Either the

2025arguments to
2026.Fl r .
2027.It Fl c
2028Display cached attributes.
2029If the device supports this flag, it allows displaying attributes for the
2030last piece of media loaded in the drive.
2031.It Fl e Ar num
2032Specify the element address.
2033This is used for specifying which element number in a medium changer to
2034access when reading attributes.
2035The element number could be for a picker, portal, slot or drive.
2036.It Fl F Ar form1,form2
2037Specify the output format for the attribute values (attr_val) display as a
2038comma separated list of options.
2039The default output is currently set to field_all,nonascii_trim,text_raw.
2040Once this code is ported to FreeBSD 10, any text fields will be converted
2041from their codeset to the user's native codeset with
2042.Xr iconv 3 .
2043.Pp
2044The text options are mutually exclusive; if you specify more than one, you
2045will get unpredictable results.
2046The nonascii options are also mutually exclusive.
2047Most of the field options may be logically ORed together.
2048.Bl -tag -width 12n

2061print them as they are.
2062.It field_all
2063Print all of the prefix fields: description, attribute number, attribute
2064size, and the attribute's readonly status.
2065If field_all is specified, specifying any other field options will not have
2066an effect.
2067.It field_none
2068Print none of the prefix fields, and only print out the attribute value.
2069If field_none is specified, specifying any other field options will result
2070in those fields being printed.
2071.It field_desc
2072Print out the attribute description.
2073.It field_num
2074Print out the attribute number.
2075.It field_size

2082When the media has multiple partitions, specifying different partition
2083numbers allows seeing the values for each individual partition.
2084.It Fl s Ar start_num
2085Specify the starting attribute number.
2086This requests that the target device return attribute information starting
2087at the given number.
2088.It Fl T Ar elem_type
2089Specify the element type.
2090For medium changer devices, this allows specifying the type the element
2091referenced in the element address (
2092.Fl e ) .
2093Valid types are:

2105.It Ic opcodes
2106Issue the REPORT SUPPORTED OPCODES service action of the
2107.Tn SCSI
2108MAINTENANCE IN
2109command.
2110Without arguments, this command will return a list of all
2111.Tn SCSI
2112commands supported by the device, including service actions of commands
2113that support service actions.
2114It will also include the
2115.Tn SCSI
2116CDB (Command Data Block) length for each command, and the description of
2117each command if it is known.
2118.Bl -tag -width 18n
2119.It Fl o Ar opcode
2120Request information on a specific opcode instead of the list of supported
2121commands.
2122If supported, the target will return a CDB-like structure that indicates
2123the opcode, service action (if any), and a mask of bits that are supported
2124in that CDB.
2125.It Fl s Ar service_action
2126For commands that support a service action, specify the service action to
2127query.
2128.It Fl N
2129If a service action is specified for a given opcode, and the device does
2130not support the given service action, the device should not return a
2131.Tn SCSI
2132error, but rather indicate in the returned parameter data that the command
2133is not supported.
2134By default, if a service action is specified for an opcode, and service
2135actions are not supported for the opcode in question, the device will
2136return an error.
2137.It Fl T
2138Include timeout values.
2139This option works with the default display, which includes all commands
2140supported by the device, and with the
2141.Fl o
2142and
2143.Fl s
2144options, which request information on a specific command and service
2145action.
2146This requests that the device report Nominal and Recommended timeout values
2147for the given command or commands.
2148The timeout values are in seconds.
2149The timeout descriptor also includes a command-specific

2151.It Ic zone
2152Manage
2153.Tn SCSI
2154and
2155.Tn ATA
2156Zoned Block devices.
2157This allows managing devices that conform to the
2158.Tn SCSI
2159Zoned Block Commands (ZBC) and
2160.Tn ATA
2161Zoned ATA Command Set (ZAC)
2162specifications.
2163Devices using these command sets are usually hard drives using Shingled
2164Magnetic Recording (SMR).
2165There are three types of SMR drives:
2166.Bl -tag -width 13n
2167.It Drive Managed
2168Drive Managed drives look and act just like a standard random access block
2169device, but underneath, the drive reads and writes the bulk of its capacity
2170using SMR zones.
2171Sequential writes will yield better performance, but writing sequentially
2172is not required.
2173.It Host Aware
2174Host Aware drives expose the underlying zone layout via
2175.Tn SCSI
2176or
2177.Tn ATA
2178commands and allow the host to manage the zone conditions.
2179The host is not required to manage the zones on the drive, though.
2180Sequential writes will yield better performance in Sequential Write
2181Preferred zones, but the host can write randomly in those zones.
2182.It Host Managed
2183Host Managed drives expose the underlying zone layout via
2184.Tn SCSI
2185or
2186.Tn ATA
2187commands.
2188The host is required to access the zones according to the rules described
2189by the zone layout.
2190Any commands that violate the rules will be returned with an error.
2191.El
2192.Pp
2193SMR drives are divided into zones (typically in the range of 256MB each)
2194that fall into three general categories:
2195.Bl -tag -width 20n
2196.It Conventional
2197These are also known as Non Write Pointer zones.
2198These zones can be randomly written without an unexpected performance penalty.
2199.It Sequential Preferred
2200These zones should be written sequentially starting at the write pointer
2201for the zone.
2202They may be written randomly.
2203Writes that do not conform to the zone layout may be significantly slower
2204than expected.
2205.It Sequential Required
2206These zones must be written sequentially.
2207If they are not written sequentially, starting at the write pointer, the
2208command will fail.

2233.It rwp
2234Reset the write pointer for the zone specified by the starting LBA.
2235.El
2236.It Fl a
2237For the Open, Close, Finish, and Reset Write Pointer operations, apply the
2238operation to all zones on the drive.
2239.It Fl l Ar lba
2240Specify the starting LBA.
2241For the Report Zones command, this tells the drive to report starting with
2242the zone that starts at the given LBA.
2243For the other commands, this allows the user to identify the zone requested
2244by its starting LBA.
2245The LBA may be specified in decimal, hexadecimal or octal notation.
2246.It Fl o Ar rep_opt
2247For the Report Zones command, specify a subset of zones to report.
2248.Bl -tag -width 8n

2251This is the default.
2252.It emtpy
2253Report only empty zones.
2254.It imp_open
2255Report zones that are implicitly open.
2256This means that the host has sent a write to the zone without explicitly
2257opening the zone.
2258.It exp_open
2259Report zones that are explicitly open.
2260.It closed
2261Report zones that have been closed by the host.
2262.It full

2268is also accepted as an argument.
2269.It offline
2270Report zones that are in the offline state.
2271.It reset
2272Report zones where the device recommends resetting write pointers.
2273.It nonseq
2274Report zones that have the Non Sequential Resources Active flag set.
2275These are zones that are Sequential Write Preferred, but have been written
2276non-sequentially.
2277.It nonwp
2278Report Non Write Pointer zones, also known as Conventional zones.

2285This is the default.
2286The summary and column headings are printed, fields are separated by spaces
2287and the fields themselves may contain spaces.
2288.It summary
2289Just print the summary:  the number of zones, the maximum LBA (LBA of the
2290last logical block on the drive), and the value of the
2291.Dq same
2292field.
2293The
2294.Dq same
2295field describes whether the zones on the drive are all identical, all
2296different, or whether they are the same except for the last zone, etc.
2297.It script
2298Print the zones in a script friendly format.
2299The summary and column headings are omitted, the fields are separated by

2863.Sh BUGS
2864The code that parses the generic command line arguments does not know that
2865some of the subcommands take multiple arguments.
2866So if, for instance, you
2867tried something like this:
2868.Bd -literal -offset indent
2869camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
2870.Ed
2871.Pp
2872The sense information from the test unit ready command would not get
2873printed out, since the first
2874.Xr getopt 3
2875call in
2876.Nm
2877bails out when it sees the second argument to
2878.Fl c
2879(0x00),
2880above.
2881Fixing this behavior would take some gross code, or changes to the
2882.Xr getopt 3
2883interface.
2884The best way to circumvent this problem is to always make sure
2885to specify generic
2886.Nm
2887arguments before any command-specific arguments.
2888
