351.Ic help
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), or bus:target:lun
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.It Ic reprobe
588Tell the kernel to refresh the information about the device and
589notify the upper layer,
590.Xr GEOM 4 .
591This includes sending the SCSI READ CAPACITY command and updating
592the disk size visible to the rest of the system.
593.It Ic reset
594Tell the kernel to reset all buses in the system (with the
595.Ar all
596argument) or the given bus (XPT_RESET_BUS) by issuing a SCSI bus
597reset for that bus, or to reset the given bus:target:lun
598(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
599connecting to that device.
600Note that this can have a destructive impact
601on the system.
602.It Ic defects
603Send the
604.Tn SCSI
605READ DEFECT DATA (10) command (0x37) or the
606.Tn SCSI
607READ DEFECT DATA (12) command (0xB7) to the given device, and
608print out any combination of: the total number of defects, the primary
609defect list (PLIST), and the grown defect list (GLIST).
610.Bl -tag -width 11n
611.It Fl f Ar format
612Specify the requested format of the defect list.
613The format argument is
614required.
615Most drives support the physical sector format.
616Some drives
617support the logical block format.
618Many drives, if they do not support the
619requested format, return the data in an alternate format, along with sense
620information indicating that the requested data format is not supported.
621The
622.Nm
623utility
624attempts to detect this, and print out whatever format the drive returns.
625If the drive uses a non-standard sense code to report that it does not
626support the requested format,
627.Nm
628will probably see the error as a failure to complete the request.
629.Pp
630The format options are:
631.Bl -tag -width 9n
632.It block
633Print out the list as logical blocks.
634This is limited to 32-bit block sizes, and isn't supported by many modern
635drives.
636.It longblock
637Print out the list as logical blocks.
638This option uses a 64-bit block size.
639.It bfi
640Print out the list in bytes from index format.
641.It extbfi
642Print out the list in extended bytes from index format.
643The extended format allows for ranges of blocks to be printed.
644.It phys
645Print out the list in physical sector format.
646Most drives support this format.
647.It extphys
648Print out the list in extended physical sector format.
649The extended format allows for ranges of blocks to be printed.
650.El
651.It Fl G
652Print out the grown defect list.
653This is a list of bad blocks that have
654been remapped since the disk left the factory.
655.It Fl P
656Print out the primary defect list.
657This is the list of defects that were present in the factory.
658.It Fl q
659When printing status information with
660.Fl s ,
661only print the number of defects.
662.It Fl s
663Just print the number of defects, not the list of defects.
664.It Fl S Ar offset
665Specify the starting offset into the defect list.
666This implies using the
667.Tn SCSI
668READ DEFECT DATA (12) command, as the 10 byte version of the command
669doesn't support the address descriptor index field.
670Not all drives support the 12 byte command, and some drives that support
671the 12 byte command don't support the address descriptor index field.
672.It Fl X

683returned from the drive.
684Some drives will report 0 defects if neither the primary or grown defect
685lists are requested.
686.It Ic modepage
687Allows the user to display and optionally edit a SCSI mode page.
688The mode
689page formats are located in
690.Pa /usr/share/misc/scsi_modes .
691This can be overridden by specifying a different file in the
692.Ev SCSI_MODES
693environment variable.
694The
695.Ic modepage
696command takes several arguments:
697.Bl -tag -width 12n
698.It Fl d
699Disable block descriptors for mode sense.
700.It Fl b
701Displays mode page data in binary format.
702.It Fl e
703This flag allows the user to edit values in the mode page.
704The user may
705either edit mode page values with the text editor pointed to by his
706.Ev EDITOR
707environment variable, or supply mode page values via standard input, using
708the same format that
709.Nm
710uses to display mode page values.
711The editor will be invoked if
712.Nm
713detects that standard input is terminal.
714.It Fl l
715Lists all available mode pages.
716If specified more then once, also lists subpages.
717.It Fl m Ar page[,subpage]
718This specifies the number of the mode page and optionally subpage the user

736.El
737.It Ic cmd
738Allows the user to send an arbitrary ATA or SCSI CDB to any device.
739The
740.Ic cmd
741function requires the
742.Fl c
743argument to specify SCSI CDB or the
744.Fl a
745argument to specify ATA Command Block registers values.
746Other arguments are optional, depending on
747the command type.
748The command and data specification syntax is documented
749in
750.Xr cam_cdbparse 3 .
751NOTE: If the CDB specified causes data to be transferred to or from the

78711 result registers will be written to standard output in hex.
788.El
789.It Ic smpcmd
790Allows the user to send an arbitrary Serial
791Management Protocol (SMP) command to a device.
792The
793.Ic smpcmd
794function requires the
795.Fl r
796argument to specify the SMP request to be sent, and the
797.Fl R
798argument to specify the format of the SMP response.
799The syntax for the SMP request and response arguments is documented in
800.Xr cam_cdbparse 3 .
801.Pp
802Note that SAS adapters that support SMP passthrough (at least the currently
803known adapters) do not accept CRC bytes from the user in the request and do
804not pass CRC bytes back to the user in the response.
805Therefore users should not include the CRC bytes in the length of the
806request and not expect CRC bytes to be returned in the response.
807.Bl -tag -width 17n
808.It Fl r Ar len Ar fmt Op args
809This specifies the size of the SMP request, without the CRC bytes, and the
810SMP request format.

813.Ar len
814bytes of data will be read from standard input and written as the SMP
815request.
816.It Fl R Ar len Ar fmt Op args
817This specifies the size of the buffer allocated for the SMP response, and
818the SMP response format.
819If the format is
820.Sq - ,
821.Ar len
822bytes of data will be allocated for the response and the response will be
823written to standard output.
824.El
825.It Ic smprg
826Allows the user to send the Serial Management Protocol (SMP) Report General
827command to a device.
828.Nm

830If the SMP target supports the long response format, the additional data
831will be requested and displayed automatically.
832.Bl -tag -width 8n
833.It Fl l
834Request the long response format only.
835Not all SMP targets support the long response format.
836This option causes
837.Nm
838to skip sending the initial report general request without the long bit set
839and only issue a report general request with the long bit set.
840.El
841.It Ic smppc
842Allows the user to issue the Serial Management Protocol (SMP) PHY Control
843command to a device.
844This function should be used with some caution, as it can render devices
845inaccessible, and could potentially cause data corruption as well.
846The
847.Fl p
848argument is required to specify the PHY to operate on.
849.Bl -tag -width 17n
850.It Fl p Ar phy
851Specify the PHY to operate on.
852This argument is required.
853.It Fl l
854Request the long request/response format.
855Not all SMP targets support the long response format.
856For the PHY Control command, this currently only affects whether the
857request length is set to a value other than 0.
858.It Fl o Ar operation
859Specify a PHY control operation.
860Only one
861.Fl o
862operation may be specified.

870Send the LINK RESET command to the phy.
871.It hardreset
872Send the HARD RESET command to the phy.
873.It disable
874Send the DISABLE command to the phy.
875Note that the LINK RESET or HARD RESET commands should re-enable the phy.
876.It clearerrlog
877Send the CLEAR ERROR LOG command.
878This clears the error log counters for the specified phy.
879.It clearaffiliation
880Send the CLEAR AFFILIATION command.
881This clears the affiliation from the STP initiator port with the same SAS
882address as the SMP initiator that requests the clear operation.
883.It sataportsel
884Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
885This will cause a SATA port selector to use the given phy as its active phy
886and make the other phy inactive.
887.It clearitnl
888Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
889.It setdevname
890Send the SET ATTACHED DEVICE NAME command to the PHY.
891This requires the

961.It Ic debug
962Turn on CAM debugging printfs in the kernel.
963This requires options CAMDEBUG
964in your kernel config file.
965WARNING: enabling debugging printfs currently
966causes an EXTREME number of kernel printfs.
967You may have difficulty
968turning off the debugging printfs once they start, since the kernel will be
969busy printing messages and unable to service other requests quickly.
970The
971.Ic debug
972function takes a number of arguments:
973.Bl -tag -width 18n
974.It Fl I
975Enable CAM_DEBUG_INFO printfs.

994.It bus Ns Op :target Ns Op :lun
995Turn on debugging for the given bus, target or lun.
996If the lun or target
997and lun are not specified, they are wildcarded.
998(i.e., just specifying a
999bus turns on debugging printfs for all devices on that bus.)
1000.El
1001.It Ic tags
1002Show or set the number of "tagged openings" or simultaneous transactions
1003we attempt to queue to a particular device.
1004By default, the
1005.Ic tags
1006command, with no command-specific arguments (i.e., only generic arguments)
1007prints out the "soft" maximum number of transactions that can be queued to
1008the device in question.
1009For more detailed information, use the
1010.Fl v
1011argument described below.
1012.Bl -tag -width 7n
1013.It Fl N Ar tags
1014Set the number of tags for the given device.
1015This must be between the
1016minimum and maximum number set in the kernel quirk table.
1017The default for
1018most devices that support tagged queueing is a minimum of 2 and a maximum
1019of 255.
1020The minimum and maximum values for a given device may be
1021determined by using the
1022.Fl v
1023switch.
1024The meaning of the
1025.Fl v
1026switch for this
1027.Nm
1028subcommand is described below.
1029.It Fl q
1030Be quiet, and do not report the number of tags.
1031This is generally used when
1032setting the number of tags.
1033.It Fl v
1034The verbose flag has special functionality for the
1035.Em tags
1036argument.
1037It causes
1038.Nm
1039to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB:
1040.Bl -tag -width 13n
1041.It dev_openings
1042This is the amount of capacity for transactions queued to a given device.
1043.It dev_active
1044This is the number of transactions currently queued to a device.
1045.It devq_openings
1046This is the kernel queue space for transactions.
1047This count usually mirrors
1048dev_openings except during error recovery operations when
1049the device queue is frozen (device is not allowed to receive
1050commands), the number of dev_openings is reduced, or transaction
1051replay is occurring.
1052.It devq_queued
1053This is the number of transactions waiting in the kernel queue for capacity
1054on the device.
1055This number is usually zero unless error recovery is in
1056progress.
1057.It held
1058The held count is the number of CCBs held by peripheral drivers that have
1059either just been completed or are about to be released to the transport
1060layer for service by a device.
1061Held CCBs reserve capacity on a given
1062device.
1063.It mintags
1064This is the current "hard" minimum number of transactions that can be
1065queued to a device at once.
1066The
1067.Ar dev_openings
1068value above cannot go below this number.
1069The default value for
1070.Ar mintags
1071is 2, although it may be set higher or lower for various devices.
1072.It maxtags
1073This is the "hard" maximum number of transactions that can be queued to a
1074device at one time.
1075The
1076.Ar dev_openings
1077value cannot go above this number.
1078The default value for
1079.Ar maxtags
1080is 255, although it may be set higher or lower for various devices.
1081.El
1082.El
1083.It Ic negotiate
1084Show or negotiate various communication parameters.
1085Some controllers may
1086not support setting or changing some of these values.
1087For instance, the
1088Adaptec 174x controllers do not support changing a device's sync rate or
1089offset.
1090The
1091.Nm
1092utility
1093will not attempt to set the parameter if the controller indicates that it
1094does not support setting the parameter.
1095To find out what the controller
1096supports, use the
1097.Fl v
1098flag.
1099The meaning of the
1100.Fl v
1101flag for the
1102.Ic negotiate
1103command is described below.
1104Also, some controller drivers do not support
1105setting negotiation parameters, even if the underlying controller supports
1106negotiation changes.
1107Some controllers, such as the Advansys wide
1108controllers, support enabling and disabling synchronous negotiation for
1109a device, but do not support setting the synchronous negotiation rate.
1110.Bl -tag -width 17n
1111.It Fl a
1112Attempt to make the negotiation settings take effect immediately by sending
1113a Test Unit Ready command to the device.

1116This is the default.
1117.It Fl D Ar enable|disable
1118Enable or disable disconnection.
1119.It Fl M Ar mode
1120Set ATA mode.
1121.It Fl O Ar offset
1122Set the command delay offset.
1123.It Fl q
1124Be quiet, do not print anything.
1125This is generally useful when you want to
1126set a parameter, but do not want any status information.
1127.It Fl R Ar syncrate
1128Change the synchronization rate for a device.
1129The sync rate is a floating
1130point value specified in MHz.
1131So, for instance,
1132.Sq 20.000
1133is a legal value, as is
1134.Sq 20 .
1135.It Fl T Ar enable|disable
1136Enable or disable tagged queueing for a device.
1137.It Fl U
1138Show or set user negotiation settings.
1139The default is to show or set
1140current negotiation settings.
1141.It Fl v
1142The verbose switch has special meaning for the
1143.Ic negotiate
1144subcommand.
1145It causes
1146.Nm
1147to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the
1148controller driver.
1149.It Fl W Ar bus_width
1150Specify the bus width to negotiate with a device.
1151The bus width is
1152specified in bits.
1153The only useful values to specify are 8, 16, and 32
1154bits.
1155The controller must support the bus width in question in order for
1156the setting to take effect.
1157.El
1158.Pp
1159In general, sync rate and offset settings will not take effect for a
1160device until a command has been sent to the device.
1161The
1162.Fl a
1163switch above will automatically send a Test Unit Ready to the device so
1164negotiation parameters will take effect.
1165.It Ic format

1168FORMAT UNIT command to the named device.
1169.Pp
1170.Em WARNING! WARNING! WARNING!
1171.Pp
1172Low level formatting a disk will destroy ALL data on the disk.
1173Use
1174extreme caution when issuing this command.
1175Many users low-level format
1176disks that do not really need to be low-level formatted.
1177There are
1178relatively few scenarios that call for low-level formatting a disk.
1179One reason for
1180low-level formatting a disk is to initialize the disk after changing
1181its physical sector size.
1182Another reason for low-level formatting a disk
1183is to revive the disk if you are getting "medium format corrupted" errors
1184from the disk in response to read and write requests.
1185.Pp
1186Some disks take longer than others to format.
1187Users should specify a
1188timeout long enough to allow the format to complete.
1189The default format
1190timeout is 3 hours, which should be long enough for most disks.
1191Some hard
1192disks will complete a format operation in a very short period of time
1193(on the order of 5 minutes or less).
1194This is often because the drive
1195does not really support the FORMAT UNIT command -- it just accepts the
1196command, waits a few minutes and then returns it.
1197.Pp
1198The
1199.Sq format
1200subcommand takes several arguments that modify its default behavior.
1201The
1202.Fl q
1203and
1204.Fl y
1205arguments can be useful for scripts.
1206.Bl -tag -width 6n
1207.It Fl q
1208Be quiet, do not print any status messages.
1209This option will not disable
1210the questions, however.
1211To disable questions, use the
1212.Fl y
1213argument, below.
1214.It Fl r
1215Run in
1216.Dq report only
1217mode.
1218This will report status on a format that is already running on the drive.
1219.It Fl w
1220Issue a non-immediate format command.
1221By default,
1222.Nm
1223issues the FORMAT UNIT command with the immediate bit set.
1224This tells the
1225device to immediately return the format command, before the format has
1226actually completed.
1227Then,
1228.Nm
1229gathers
1230.Tn SCSI
1231sense information from the device every second to determine how far along
1232in the format process it is.
1233If the
1234.Fl w
1235argument is specified,
1236.Nm
1237will issue a non-immediate format command, and will be unable to print any
1238information to let the user know what percentage of the disk has been
1239formatted.
1240.It Fl y
1241Do not ask any questions.
1242By default,
1243.Nm
1244will ask the user if he/she really wants to format the disk in question,
1245and also if the default format command timeout is acceptable.
1246The user
1247will not be asked about the timeout if a timeout is specified on the
1248command line.

2104commands supported by the device, including service actions of commands
2105that support service actions.
2106It will also include the

2109each command if it is known.
2110.Bl -tag -width 18n
2111.It Fl o Ar opcode
2112Request information on a specific opcode instead of the list of supported
2113commands.
2114If supported, the target will return a CDB-like structure that indicates
2115the opcode, service action (if any), and a mask of bits that are supported
2116in that CDB.
2117.It Fl s Ar service_action
2118For commands that support a service action, specify the service action to
2119query.
2120.It Fl N
2121If a service action is specified for a given opcode, and the device does
2122not support the given service action, the device should not return a
2123.Tn SCSI
2124error, but rather indicate in the returned parameter data that the command
2125is not supported.
2126By default, if a service action is specified for an opcode, and service
2127actions are not supported for the opcode in question, the device will
2128return an error.
2129.It Fl T
2130Include timeout values.
2131This option works with the default display, which includes all commands
2132supported by the device, and with the
2133.Fl o
2134and
2135.Fl s
2136options, which request information on a specific command and service
2137action.
2138This requests that the device report Nominal and Recommended timeout values
2139for the given command or commands.
2140The timeout values are in seconds.

2149This allows managing devices that conform to the
2150.Tn SCSI
2151Zoned Block Commands (ZBC) and
2152.Tn ATA
2153Zoned ATA Command Set (ZAC)
2154specifications.
2155Devices using these command sets are usually hard drives using Shingled
2156Magnetic Recording (SMR).
2157There are three types of SMR drives:
2158.Bl -tag -width 13n
2159.It Drive Managed
2160Drive Managed drives look and act just like a standard random access block
2161device, but underneath, the drive reads and writes the bulk of its capacity
2162using SMR zones.
2163Sequential writes will yield better performance, but writing sequentially
2164is not required.
2165.It Host Aware
2166Host Aware drives expose the underlying zone layout via
2167.Tn SCSI
2168or
2169.Tn ATA
2170commands and allow the host to manage the zone conditions.
2171The host is not required to manage the zones on the drive, though.
2172Sequential writes will yield better performance in Sequential Write
2173Preferred zones, but the host can write randomly in those zones.
2174.It Host Managed
2175Host Managed drives expose the underlying zone layout via
2176.Tn SCSI
2177or
2178.Tn ATA
2179commands.
2180The host is required to access the zones according to the rules described
2181by the zone layout.
2182Any commands that violate the rules will be returned with an error.
2183.El
2184.Pp
2185SMR drives are divided into zones (typically in the range of 256MB each)
2186that fall into three general categories:
2187.Bl -tag -width 20n
2188.It Conventional
2189These are also known as Non Write Pointer zones.
2190These zones can be randomly written without an unexpected performance penalty.
2191.It Sequential Preferred
2192These zones should be written sequentially starting at the write pointer
2193for the zone.
2194They may be written randomly.
2195Writes that do not conform to the zone layout may be significantly slower
2196than expected.
2197.It Sequential Required
2198These zones must be written sequentially.
2199If they are not written sequentially, starting at the write pointer, the
2200command will fail.

2229For the Open, Close, Finish, and Reset Write Pointer operations, apply the
2230operation to all zones on the drive.
2231.It Fl l Ar lba
2232Specify the starting LBA.
2233For the Report Zones command, this tells the drive to report starting with
2234the zone that starts at the given LBA.
2235For the other commands, this allows the user to identify the zone requested
2236by its starting LBA.
2237The LBA may be specified in decimal, hexadecimal or octal notation.

2244.It emtpy
2245Report only empty zones.
2246.It imp_open
2247Report zones that are implicitly open.
2248This means that the host has sent a write to the zone without explicitly
2249opening the zone.
2250.It exp_open
2251Report zones that are explicitly open.
2252.It closed
2253Report zones that have been closed by the host.

2855.Sh BUGS
2856The code that parses the generic command line arguments does not know that
2857some of the subcommands take multiple arguments.
2858So if, for instance, you
2859tried something like this:
2860.Bd -literal -offset indent
2861camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
2862.Ed
2863.Pp
2864The sense information from the test unit ready command would not get
2865printed out, since the first
2866.Xr getopt 3
2867call in
2868.Nm
2869bails out when it sees the second argument to
2870.Fl c
2871(0x00),
2872above.
2873Fixing this behavior would take some gross code, or changes to the
2874.Xr getopt 3
2875interface.
2876The best way to circumvent this problem is to always make sure
2877to specify generic
2878.Nm
2879arguments before any command-specific arguments.
2880
