381.Sh DESCRIPTION
382The
383.Nm
384utility allows users to access and control the
385.Fx
386CAM subsystem described in
387.Xr cam 4 .
388.Pp
389The
390.Nm
391utility
392can cause a loss of data and/or system crashes if used improperly.
393Even
394expert users are encouraged to exercise caution when using this command.
395Novice users should stay away from this utility.
396.Pp
397The
398.Nm
399utility has a number of primary functions, many of which support an optional
400device identifier.
401A device identifier can take one of three forms:
402.Bl -tag -width 14n
403.It deviceUNIT
404Specify a device name and unit number combination, like "da5" or "cd3".
405.It bus:target
406Specify a bus number and target id.
407The bus number can be determined from
408the output of
409.Dq camcontrol devlist .
410The lun defaults to 0.
411.It bus:target:lun
412Specify the bus, target and lun for a device.
413(e.g.\& 1:2:0)
414.El
415.Pp
416The device identifier, if it is specified,
417.Em must
418come immediately after the function name, and before any generic or
419function-specific arguments.
420Note that the
421.Fl n
422and
423.Fl u
424arguments described below will override any device name or unit number
425specified beforehand.
426The
427.Fl n
428and
429.Fl u
430arguments will
431.Em not
432override a specified bus:target or bus:target:lun, however.
433.Pp
434Most of the
435.Nm
436primary functions support these generic arguments:
437.Bl -tag -width 14n
438.It Fl C Ar count
439SCSI command retry count.
440In order for this to work, error recovery
441.Pq Fl E
442must be turned on.
443.It Fl E
444Instruct the kernel to perform generic SCSI error recovery for the given
445command.
446This is needed in order for the retry count
447.Pq Fl C
448to be honored.
449Other than retrying commands, the generic error recovery in
450the code will generally attempt to spin up drives that are not spinning.
451It may take some other actions, depending upon the sense code returned from
452the command.
453.It Fl n Ar dev_name
454Specify the device type to operate on, e.g.\& "da", "cd".
455.It Fl Q Ar task_attr
456.Tn SCSI
457task attribute for the command, if it is a
458.Tn SCSI
459command.
460This may be ordered, simple, head, or aca.
461In most cases this is not needed.
462The default is simple, which works with all
463.Tn SCSI
464devices.
465The task attribute may also be specified numerically.
466.It Fl t Ar timeout
467SCSI command timeout in seconds.
468This overrides the default timeout for
469any given command.
470.It Fl u Ar unit_number
471Specify the device unit number, e.g.\& "1", "5".
472.It Fl v
473Be verbose, print out sense information for failed SCSI commands.
474.El
475.Pp
476Primary command functions:
477.Bl -tag -width periphlist
478.It Ic devlist
479List all physical devices (logical units) attached to the CAM subsystem.
480This also includes a list of peripheral drivers attached to each device.
481With the
482.Fl v
483argument, SCSI bus number, adapter name and unit numbers are printed as
484well.
485On the other hand, with the
486.Fl b
487argument, only the bus adapter, and unit information will be printed, and
488device information will be omitted.
489.It Ic periphlist
490List all peripheral drivers attached to a given physical device (logical
491unit).
492.It Ic tur
493Send the SCSI test unit ready (0x00) command to the given device.
494The
495.Nm
496utility will report whether the device is ready or not.
497.It Ic sense
498Send a SCSI REQUEST SENSE command (0x03) to a device.
499The decoded sense (or hexdump) is printed to stdout.
500.Bl -tag -width 4n
501.It Fl D
502Request descriptor sense instead of fixed sense.
503.It Fl x
504Do a hexdump of the returned sense data.
505.El
506.It Ic inquiry
507Send a SCSI inquiry command (0x12) to a device.
508By default,
509.Nm
510will print out the standard inquiry data, device serial number, and
511transfer rate information.
512The user can specify that only certain types of
513inquiry data be printed:
514.Bl -tag -width 4n
515.It Fl D
516Get the standard inquiry data.
517.It Fl S
518Print out the serial number.
519If this flag is the only one specified,
520.Nm
521will not print out "Serial Number" before the value returned by the drive.
522This is to aid in script writing.
523.It Fl R
524Print out transfer rate information.
525.El
526.It Ic identify
527Send an ATA identify command (0xec) to a device.
528.It Ic reportluns
529Send the SCSI REPORT LUNS (0xA0) command to the given device.
530By default,
531.Nm
532will print out the list of logical units (LUNs) supported by the target device.
533There are a couple of options to modify the output:
534.Bl -tag -width 14n
535.It Fl c
536Just print out a count of LUNs, not the actual LUN numbers.
537.It Fl l
538Just print out the LUNs, and do not print out the count.
539.It Fl r Ar reporttype
540Specify the type of report to request from the target:
541.Bl -tag -width 012345678
542.It default
543Return the default report.
544This is the
545.Nm
546default.
547Most targets will support this report if they support the REPORT LUNS
548command.
549.It wellknown
550Return only well known LUNs.
551.It all
552Return all available LUNs.
553.El
554.El
555.Pp
556.Nm
557will try to print out LUN numbers in a reasonable format.
558It can understand the peripheral, flat, LUN and extended LUN formats.
559.It Ic readcap
560Send the SCSI READ CAPACITY command to the given device and display
561the results.
562If the device is larger than 2TB, the SCSI READ CAPACITY (16) service
563action will be sent to obtain the full size of the device.
564By default,
565.Nm
566will print out the last logical block of the device, and the blocksize of
567the device in bytes.
568To modify the output format, use the following options:
569.Bl -tag -width 5n
570.It Fl b
571Just print out the blocksize, not the last block or device size.
572This cannot be used with
573.Fl N
574or
575.Fl s .
576.It Fl h
577Print out the device size in human readable (base 2, 1K == 1024) format.
578This implies
579.Fl N
580and cannot be used with
581.Fl q
582or
583.Fl b .
584.It Fl H
585Print out the device size in human readable (base 10, 1K == 1000) format.
586.It Fl l
587Skip sending the SCSI READ CAPACITY (10) command.
588Send only the SCSI READ CAPACITY (16) service action and report
589its results.
590When the two do not match, a quirk is needed to resolve the ambiguity.
591.It Fl N
592Print out the number of blocks in the device instead of the last logical
593block.
594.It Fl q
595Quiet, print out the numbers only (separated by a comma if
596.Fl b
597or
598.Fl s
599are not specified).
600.It Fl s
601Print out the last logical block or the size of the device only, and omit
602the blocksize.
603.El
604.Pp
605Note that this command only displays the information, it does not update
606the kernel data structures.
607Use the
608.Nm
609reprobe subcommand to do that.
610.It Ic start
611Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
612start bit set.
613.It Ic stop
614Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
615start bit cleared.
616.It Ic load
617Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
618start bit set and the load/eject bit set.
619.It Ic eject
620Send the SCSI Start/Stop Unit (0x1B) command to the given device with the
621start bit cleared and the load/eject bit set.
622.It Ic rescan
623Tell the kernel to scan all buses in the system (with the
624.Ar all
625argument), the given bus (XPT_SCAN_BUS), bus:target:lun or device
626(XPT_SCAN_LUN) for new devices or devices that have gone away.
627The user
628may specify a scan of all buses, a single bus, or a lun.
629Scanning all luns
630on a target is not supported.
631.Pp
632If a device is specified by peripheral name and unit number, for instance
633da4, it may only be rescanned if that device currently exists in the CAM EDT
634(Existing Device Table).
635If the device is no longer there (see
636.Nm
637devlist ),
638you must use the bus:target:lun form to rescan it.
639.It Ic reprobe
640Tell the kernel to refresh the information about the device and
641notify the upper layer,
642.Xr GEOM 4 .
643This includes sending the SCSI READ CAPACITY command and updating
644the disk size visible to the rest of the system.
645.It Ic reset
646Tell the kernel to reset all buses in the system (with the
647.Ar all
648argument), the given bus (XPT_RESET_BUS) by issuing a SCSI bus
649reset for that bus, or to reset the given bus:target:lun or device
650(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after
651connecting to that device.
652Note that this can have a destructive impact
653on the system.
654.It Ic defects
655Send the
656.Tn SCSI
657READ DEFECT DATA (10) command (0x37) or the
658.Tn SCSI
659READ DEFECT DATA (12) command (0xB7) to the given device, and
660print out any combination of: the total number of defects, the primary
661defect list (PLIST), and the grown defect list (GLIST).
662.Bl -tag -width 11n
663.It Fl f Ar format
664Specify the requested format of the defect list.
665The format argument is
666required.
667Most drives support the physical sector format.
668Some drives
669support the logical block format.
670Many drives, if they do not support the
671requested format, return the data in an alternate format, along with sense
672information indicating that the requested data format is not supported.
673The
674.Nm
675utility
676attempts to detect this, and print out whatever format the drive returns.
677If the drive uses a non-standard sense code to report that it does not
678support the requested format,
679.Nm
680will probably see the error as a failure to complete the request.
681.Pp
682The format options are:
683.Bl -tag -width 9n
684.It block
685Print out the list as logical blocks.
686This is limited to 32-bit block sizes, and isn't supported by many modern
687drives.
688.It longblock
689Print out the list as logical blocks.
690This option uses a 64-bit block size.
691.It bfi
692Print out the list in bytes from index format.
693.It extbfi
694Print out the list in extended bytes from index format.
695The extended format allows for ranges of blocks to be printed.
696.It phys
697Print out the list in physical sector format.
698Most drives support this format.
699.It extphys
700Print out the list in extended physical sector format.
701The extended format allows for ranges of blocks to be printed.
702.El
703.It Fl G
704Print out the grown defect list.
705This is a list of bad blocks that have
706been remapped since the disk left the factory.
707.It Fl P
708Print out the primary defect list.
709This is the list of defects that were present in the factory.
710.It Fl q
711When printing status information with
712.Fl s ,
713only print the number of defects.
714.It Fl s
715Just print the number of defects, not the list of defects.
716.It Fl S Ar offset
717Specify the starting offset into the defect list.
718This implies using the
719.Tn SCSI
720READ DEFECT DATA (12) command, as the 10 byte version of the command
721doesn't support the address descriptor index field.
722Not all drives support the 12 byte command, and some drives that support
723the 12 byte command don't support the address descriptor index field.
724.It Fl X
725Print out defects in hexadecimal (base 16) form instead of base 10 form.
726.El
727.Pp
728If neither
729.Fl P
730nor
731.Fl G
732is specified,
733.Nm
734will print out the number of defects given in the READ DEFECT DATA header
735returned from the drive.
736Some drives will report 0 defects if neither the primary or grown defect
737lists are requested.
738.It Ic modepage
739Allows the user to display and optionally edit a SCSI mode page.
740The mode
741page formats are located in
742.Pa /usr/share/misc/scsi_modes .
743This can be overridden by specifying a different file in the
744.Ev SCSI_MODES
745environment variable.
746The
747.Ic modepage
748command takes several arguments:
749.Bl -tag -width 12n
750.It Fl 6
751Use 6 byte MODE commands instead of default 10 byte.
752Old devices may not support 10 byte MODE commands, while new devices may
753not be able to report all mode pages with 6 byte commands.
754If not specified,
755.Nm
756starts with 10 byte commands and falls back to 6 byte on error.
757.It Fl d
758Disable block descriptors for mode sense.
759.It Fl D
760Display/edit block descriptors instead of mode page.
761.It Fl L
762Use long LBA block descriptors.
763Allows number of LBAs bigger than 2^^32.
764.It Fl b
765Displays mode page data in binary format.
766.It Fl e
767This flag allows the user to edit values in the mode page.
768The user may
769either edit mode page values with the text editor pointed to by his
770.Ev EDITOR
771environment variable, or supply mode page values via standard input, using
772the same format that
773.Nm
774uses to display mode page values.
775The editor will be invoked if
776.Nm
777detects that standard input is terminal.
778.It Fl l
779Lists all available mode pages.
780If specified more than once, also lists subpages.
781.It Fl m Ar page[,subpage]
782This specifies the number of the mode page and optionally subpage the user
783would like to view and/or edit.
784This argument is mandatory unless
785.Fl l
786is specified.
787.It Fl P Ar pgctl
788This allows the user to specify the page control field.
789Possible values are:
790.Bl -tag -width xxx -compact
791.It 0
792Current values
793.It 1
794Changeable values
795.It 2

799.El
800.El
801.It Ic cmd
802Allows the user to send an arbitrary ATA or SCSI CDB to any device.
803The
804.Ic cmd
805function requires the
806.Fl c
807argument to specify SCSI CDB or the
808.Fl a
809argument to specify ATA Command Block registers values.
810Other arguments are optional, depending on
811the command type.
812The command and data specification syntax is documented
813in
814.Xr cam_cdbparse 3 .
815NOTE: If the CDB specified causes data to be transferred to or from the
816SCSI device in question, you MUST specify either
817.Fl i
818or
819.Fl o .
820.Bl -tag -width 17n
821.It Fl a Ar cmd Op args
822This specifies the content of 12 ATA Command Block registers (command,
823features, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp.
824lba_high_exp, features_exp, sector_count, sector_count_exp).
825.It Fl c Ar cmd Op args
826This specifies the SCSI CDB.
827SCSI CDBs may be 6, 10, 12 or 16 bytes.
828.It Fl d
829Specifies DMA protocol to be used for ATA command.
830.It Fl f
831Specifies FPDMA (NCQ) protocol to be used for ATA command.
832.It Fl i Ar len Ar fmt
833This specifies the amount of data to read, and how it should be displayed.
834If the format is
835.Sq - ,
836.Ar len
837bytes of data will be read from the device and written to standard output.
838.It Fl o Ar len Ar fmt Op args
839This specifies the amount of data to be written to a device, and the data
840that is to be written.
841If the format is
842.Sq - ,
843.Ar len
844bytes of data will be read from standard input and written to the device.
845.It Fl r Ar fmt
846This specifies that 11 result ATA Command Block registers should be displayed
847(status, error, lba_low, lba_mid, lba_high, device, lba_low_exp, lba_mid_exp,
848lba_high_exp, sector_count, sector_count_exp), and how.
849If the format is
850.Sq - ,
85111 result registers will be written to standard output in hex.
852.El
853.It Ic smpcmd
854Allows the user to send an arbitrary Serial
855Management Protocol (SMP) command to a device.
856The
857.Ic smpcmd
858function requires the
859.Fl r
860argument to specify the SMP request to be sent, and the
861.Fl R
862argument to specify the format of the SMP response.
863The syntax for the SMP request and response arguments is documented in
864.Xr cam_cdbparse 3 .
865.Pp
866Note that SAS adapters that support SMP passthrough (at least the currently
867known adapters) do not accept CRC bytes from the user in the request and do
868not pass CRC bytes back to the user in the response.
869Therefore users should not include the CRC bytes in the length of the
870request and not expect CRC bytes to be returned in the response.
871.Bl -tag -width 17n
872.It Fl r Ar len Ar fmt Op args
873This specifies the size of the SMP request, without the CRC bytes, and the
874SMP request format.
875If the format is
876.Sq - ,
877.Ar len
878bytes of data will be read from standard input and written as the SMP
879request.
880.It Fl R Ar len Ar fmt Op args
881This specifies the size of the buffer allocated for the SMP response, and
882the SMP response format.
883If the format is
884.Sq - ,
885.Ar len
886bytes of data will be allocated for the response and the response will be
887written to standard output.
888.El
889.It Ic smprg
890Allows the user to send the Serial Management Protocol (SMP) Report General
891command to a device.
892.Nm
893will display the data returned by the Report General command.
894If the SMP target supports the long response format, the additional data
895will be requested and displayed automatically.
896.Bl -tag -width 8n
897.It Fl l
898Request the long response format only.
899Not all SMP targets support the long response format.
900This option causes
901.Nm
902to skip sending the initial report general request without the long bit set
903and only issue a report general request with the long bit set.
904.El
905.It Ic smppc
906Allows the user to issue the Serial Management Protocol (SMP) PHY Control
907command to a device.
908This function should be used with some caution, as it can render devices
909inaccessible, and could potentially cause data corruption as well.
910The
911.Fl p
912argument is required to specify the PHY to operate on.
913.Bl -tag -width 17n
914.It Fl p Ar phy
915Specify the PHY to operate on.
916This argument is required.
917.It Fl l
918Request the long request/response format.
919Not all SMP targets support the long response format.
920For the PHY Control command, this currently only affects whether the
921request length is set to a value other than 0.
922.It Fl o Ar operation
923Specify a PHY control operation.
924Only one
925.Fl o
926operation may be specified.
927The operation may be specified numerically (in decimal, hexadecimal, or octal)
928or one of the following operation names may be specified:
929.Bl -tag -width 16n
930.It nop
931No operation.
932It is not necessary to specify this argument.
933.It linkreset
934Send the LINK RESET command to the phy.
935.It hardreset
936Send the HARD RESET command to the phy.
937.It disable
938Send the DISABLE command to the phy.
939Note that the LINK RESET or HARD RESET commands should re-enable the phy.
940.It clearerrlog
941Send the CLEAR ERROR LOG command.
942This clears the error log counters for the specified phy.
943.It clearaffiliation
944Send the CLEAR AFFILIATION command.
945This clears the affiliation from the STP initiator port with the same SAS
946address as the SMP initiator that requests the clear operation.
947.It sataportsel
948Send the TRANSMIT SATA PORT SELECTION SIGNAL command to the phy.
949This will cause a SATA port selector to use the given phy as its active phy
950and make the other phy inactive.
951.It clearitnl
952Send the CLEAR STP I_T NEXUS LOSS command to the PHY.
953.It setdevname
954Send the SET ATTACHED DEVICE NAME command to the PHY.
955This requires the
956.Fl d
957argument to specify the device name.
958.El
959.It Fl d Ar name
960Specify the attached device name.
961This option is needed with the
962.Fl o Ar setdevname
963phy operation.
964The name is a 64-bit number, and can be specified in decimal, hexadecimal
965or octal format.
966.It Fl m Ar rate

1024.El
1025.It Ic debug
1026Turn on CAM debugging printfs in the kernel.
1027This requires options CAMDEBUG
1028in your kernel config file.
1029WARNING: enabling debugging printfs currently
1030causes an EXTREME number of kernel printfs.
1031You may have difficulty
1032turning off the debugging printfs once they start, since the kernel will be
1033busy printing messages and unable to service other requests quickly.
1034The
1035.Ic debug
1036function takes a number of arguments:
1037.Bl -tag -width 18n
1038.It Fl I
1039Enable CAM_DEBUG_INFO printfs.
1040.It Fl P
1041Enable CAM_DEBUG_PERIPH printfs.

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

2111If the device supports this flag, it allows displaying attributes for the
2112last piece of media loaded in the drive.
2113.It Fl e Ar num
2114Specify the element address.
2115This is used for specifying which element number in a medium changer to
2116access when reading attributes.
2117The element number could be for a picker, portal, slot or drive.
2118.It Fl F Ar form1,form2
2119Specify the output format for the attribute values (attr_val) display as a

2143print them as they are.
2144.It field_all
2145Print all of the prefix fields: description, attribute number, attribute
2146size, and the attribute's readonly status.
2147If field_all is specified, specifying any other field options will not have
2148an effect.
2149.It field_none
2150Print none of the prefix fields, and only print out the attribute value.
2151If field_none is specified, specifying any other field options will result
2152in those fields being printed.

2200.Bl -tag -width 18n
2201.It Fl o Ar opcode
2202Request information on a specific opcode instead of the list of supported
2203commands.
2204If supported, the target will return a CDB-like structure that indicates
2205the opcode, service action (if any), and a mask of bits that are supported
2206in that CDB.
2207.It Fl s Ar service_action
2208For commands that support a service action, specify the service action to
2209query.
2210.It Fl N
2211If a service action is specified for a given opcode, and the device does
2212not support the given service action, the device should not return a
2213.Tn SCSI
2214error, but rather indicate in the returned parameter data that the command
2215is not supported.
2216By default, if a service action is specified for an opcode, and service
2217actions are not supported for the opcode in question, the device will
2218return an error.
2219.It Fl T
2220Include timeout values.
2221This option works with the default display, which includes all commands
2222supported by the device, and with the
2223.Fl o
2224and
2225.Fl s
2226options, which request information on a specific command and service
2227action.
2228This requests that the device report Nominal and Recommended timeout values
2229for the given command or commands.
2230The timeout values are in seconds.

2240.Tn SCSI
2241Zoned Block Commands (ZBC) and
2242.Tn ATA
2243Zoned ATA Command Set (ZAC)
2244specifications.
2245Devices using these command sets are usually hard drives using Shingled
2246Magnetic Recording (SMR).
2247There are three types of SMR drives:
2248.Bl -tag -width 13n
2249.It Drive Managed
2250Drive Managed drives look and act just like a standard random access block
2251device, but underneath, the drive reads and writes the bulk of its capacity
2252using SMR zones.
2253Sequential writes will yield better performance, but writing sequentially
2254is not required.
2255.It Host Aware
2256Host Aware drives expose the underlying zone layout via
2257.Tn SCSI
2258or
2259.Tn ATA
2260commands and allow the host to manage the zone conditions.
2261The host is not required to manage the zones on the drive, though.
2262Sequential writes will yield better performance in Sequential Write
2263Preferred zones, but the host can write randomly in those zones.
2264.It Host Managed
2265Host Managed drives expose the underlying zone layout via
2266.Tn SCSI
2267or
2268.Tn ATA
2269commands.
2270The host is required to access the zones according to the rules described
2271by the zone layout.
2272Any commands that violate the rules will be returned with an error.
2273.El
2274.Pp
2275SMR drives are divided into zones (typically in the range of 256MB each)
2276that fall into three general categories:

2278.It Conventional
2279These are also known as Non Write Pointer zones.
2280These zones can be randomly written without an unexpected performance penalty.
2281.It Sequential Preferred
2282These zones should be written sequentially starting at the write pointer
2283for the zone.
2284They may be written randomly.
2285Writes that do not conform to the zone layout may be significantly slower
2286than expected.
2287.It Sequential Required

2322For the Report Zones command, this tells the drive to report starting with
2323the zone that starts at the given LBA.
2324For the other commands, this allows the user to identify the zone requested
2325by its starting LBA.
2326The LBA may be specified in decimal, hexadecimal or octal notation.

3020.Bd -literal -offset indent
3021camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v
3022.Ed
3023.Pp
3024The sense information from the test unit ready command would not get
3025printed out, since the first
3026.Xr getopt 3
3027call in
3028.Nm
3029bails out when it sees the second argument to
3030.Fl c
3031(0x00),
3032above.
3033Fixing this behavior would take some gross code, or changes to the
3034.Xr getopt 3
3035interface.
3036The best way to circumvent this problem is to always make sure
3037to specify generic
3038.Nm
3039arguments before any command-specific arguments.
