365.Nm 366.Ic devtype 367.Op device id 368.Nm 369.Ic help 370.Sh DESCRIPTION 371The 372.Nm 373utility is designed to provide a way for users to access and control the 374.Fx 375CAM subsystem. 376.Pp 377The 378.Nm 379utility 380can cause a loss of data and/or system crashes if used improperly. 381Even 382expert users are encouraged to exercise caution when using this command. 383Novice users should stay away from this utility. 384.Pp 385The 386.Nm 387utility has a number of primary functions, many of which support an optional 388device identifier. 389A device identifier can take one of three forms: 390.Bl -tag -width 14n 391.It deviceUNIT 392Specify a device name and unit number combination, like "da5" or "cd3". 393.It bus:target 394Specify a bus number and target id. 395The bus number can be determined from 396the output of 397.Dq camcontrol devlist . 398The lun defaults to 0. 399.It bus:target:lun 400Specify the bus, target and lun for a device. 401(e.g.\& 1:2:0) 402.El 403.Pp 404The device identifier, if it is specified, 405.Em must 406come immediately after the function name, and before any generic or 407function-specific arguments. 408Note that the 409.Fl n 410and 411.Fl u 412arguments described below will override any device name or unit number 413specified beforehand. 414The 415.Fl n 416and 417.Fl u 418arguments will 419.Em not 420override a specified bus:target or bus:target:lun, however. 421.Pp 422Most of the 423.Nm 424primary functions support these generic arguments: 425.Bl -tag -width 14n 426.It Fl C Ar count 427SCSI command retry count. 428In order for this to work, error recovery 429.Pq Fl E 430must be turned on. 431.It Fl E 432Instruct the kernel to perform generic SCSI error recovery for the given 433command. 434This is needed in order for the retry count 435.Pq Fl C 436to be honored. 437Other than retrying commands, the generic error recovery in 438the code will generally attempt to spin up drives that are not spinning. 439It may take some other actions, depending upon the sense code returned from 440the command. 441.It Fl n Ar dev_name 442Specify the device type to operate on, e.g.\& "da", "cd". 443.It Fl Q Ar task_attr 444.Tn SCSI 445task attribute for the command, if it is a 446.Tn SCSI 447command. 448This may be ordered, simple, head, or aca. 449In most cases this is not needed. 450The default is simple, which works with all 451.Tn SCSI 452devices. 453The task attribute may also be specified numerically. 454.It Fl t Ar timeout 455SCSI command timeout in seconds. 456This overrides the default timeout for 457any given command. 458.It Fl u Ar unit_number 459Specify the device unit number, e.g.\& "1", "5". 460.It Fl v 461Be verbose, print out sense information for failed SCSI commands. 462.El 463.Pp 464Primary command functions: 465.Bl -tag -width periphlist 466.It Ic devlist 467List all physical devices (logical units) attached to the CAM subsystem. 468This also includes a list of peripheral drivers attached to each device. 469With the 470.Fl v 471argument, SCSI bus number, adapter name and unit numbers are printed as 472well. 473On the other hand, with the 474.Fl b 475argument, only the bus adapter, and unit information will be printed, and 476device information will be omitted. 477.It Ic periphlist 478List all peripheral drivers attached to a given physical device (logical 479unit). 480.It Ic tur 481Send the SCSI test unit ready (0x00) command to the given device. 482The 483.Nm 484utility will report whether the device is ready or not. 485.It Ic inquiry 486Send a SCSI inquiry command (0x12) to a device. 487By default, 488.Nm 489will print out the standard inquiry data, device serial number, and 490transfer rate information. 491The user can specify that only certain types of 492inquiry data be printed: 493.Bl -tag -width 4n 494.It Fl D 495Get the standard inquiry data. 496.It Fl S 497Print out the serial number. 498If this flag is the only one specified, 499.Nm 500will not print out "Serial Number" before the value returned by the drive. 501This is to aid in script writing. 502.It Fl R 503Print out transfer rate information. 504.El 505.It Ic identify 506Send a ATA identify command (0xec) to a device. 507.It Ic reportluns 508Send the SCSI REPORT LUNS (0xA0) command to the given device. 509By default, 510.Nm 511will print out the list of logical units (LUNs) supported by the target device. 512There are a couple of options to modify the output: 513.Bl -tag -width 14n 514.It Fl c 515Just print out a count of LUNs, not the actual LUN numbers. 516.It Fl l 517Just print out the LUNs, and do not print out the count. 518.It Fl r Ar reporttype 519Specify the type of report to request from the target: 520.Bl -tag -width 012345678 521.It default 522Return the default report. 523This is the 524.Nm 525default. 526Most targets will support this report if they support the REPORT LUNS 527command. 528.It wellknown 529Return only well known LUNs. 530.It all 531Return all available LUNs. 532.El 533.El 534.Pp 535.Nm 536will try to print out LUN numbers in a reasonable format. 537It can understand the peripheral, flat, LUN and extended LUN formats. 538.It Ic readcap 539Send the SCSI READ CAPACITY command to the given device and display 540the results. 541If the device is larger than 2TB, the SCSI READ CAPACITY (16) service 542action will be sent to obtain the full size of the device. 543By default, 544.Nm 545will print out the last logical block of the device, and the blocksize of 546the device in bytes. 547To modify the output format, use the following options: 548.Bl -tag -width 5n 549.It Fl b 550Just print out the blocksize, not the last block or device size. 551This cannot be used with 552.Fl N 553or 554.Fl s . 555.It Fl h 556Print out the device size in human readable (base 2, 1K == 1024) format. 557This implies 558.Fl N 559and cannot be used with 560.Fl q 561or 562.Fl b . 563.It Fl H 564Print out the device size in human readable (base 10, 1K == 1000) format. 565.It Fl l 566Skip sending the SCSI READ CAPACITY (10) command. 567Send only the SCSI READ CAPACITY (16) service action and report 568its results. 569When the two do not match, a quirk is needed to resolve the ambiguity. 570.It Fl N 571Print out the number of blocks in the device instead of the last logical 572block. 573.It Fl q 574Quiet, print out the numbers only (separated by a comma if 575.Fl b 576or 577.Fl s 578are not specified). 579.It Fl s 580Print out the last logical block or the size of the device only, and omit 581the blocksize. 582.El 583.Pp 584Note that this command only displays the information, it does not update 585the kernel data structures. 586Use the 587.Nm 588reprobe subcommand to do that. 589.It Ic start 590Send the SCSI Start/Stop Unit (0x1B) command to the given device with the 591start bit set. 592.It Ic stop 593Send the SCSI Start/Stop Unit (0x1B) command to the given device with the 594start bit cleared. 595.It Ic load 596Send the SCSI Start/Stop Unit (0x1B) command to the given device with the 597start bit set and the load/eject bit set. 598.It Ic eject 599Send the SCSI Start/Stop Unit (0x1B) command to the given device with the 600start bit cleared and the load/eject bit set. 601.It Ic rescan 602Tell the kernel to scan all buses in the system (with the 603.Ar all 604argument), the given bus (XPT_SCAN_BUS), bus:target:lun or device 605(XPT_SCAN_LUN) for new devices or devices that have gone away. 606The user 607may specify a scan of all buses, a single bus, or a lun. 608Scanning all luns 609on a target is not supported. 610.Pp 611If a device is specified by peripheral name and unit number, for instance 612da4, it may only be rescanned if that device currently exists in the CAM EDT 613(Existing Device Table). 614If the device is no longer there (see 615.Nm 616devlist ), 617you must use the bus:target:lun form to rescan it. 618.It Ic reprobe 619Tell the kernel to refresh the information about the device and 620notify the upper layer, 621.Xr GEOM 4 . 622This includes sending the SCSI READ CAPACITY command and updating 623the disk size visible to the rest of the system. 624.It Ic reset 625Tell the kernel to reset all buses in the system (with the 626.Ar all 627argument), the given bus (XPT_RESET_BUS) by issuing a SCSI bus 628reset for that bus, or to reset the given bus:target:lun or device 629(XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after 630connecting to that device. 631Note that this can have a destructive impact 632on the system. 633.It Ic defects 634Send the 635.Tn SCSI 636READ DEFECT DATA (10) command (0x37) or the 637.Tn SCSI 638READ DEFECT DATA (12) command (0xB7) to the given device, and 639print out any combination of: the total number of defects, the primary 640defect list (PLIST), and the grown defect list (GLIST). 641.Bl -tag -width 11n 642.It Fl f Ar format 643Specify the requested format of the defect list. 644The format argument is 645required. 646Most drives support the physical sector format. 647Some drives 648support the logical block format. 649Many drives, if they do not support the 650requested format, return the data in an alternate format, along with sense 651information indicating that the requested data format is not supported. 652The 653.Nm 654utility 655attempts to detect this, and print out whatever format the drive returns. 656If the drive uses a non-standard sense code to report that it does not 657support the requested format, 658.Nm 659will probably see the error as a failure to complete the request. 660.Pp 661The format options are: 662.Bl -tag -width 9n 663.It block 664Print out the list as logical blocks. 665This is limited to 32-bit block sizes, and isn't supported by many modern 666drives. 667.It longblock 668Print out the list as logical blocks. 669This option uses a 64-bit block size. 670.It bfi 671Print out the list in bytes from index format. 672.It extbfi 673Print out the list in extended bytes from index format. 674The extended format allows for ranges of blocks to be printed. 675.It phys 676Print out the list in physical sector format. 677Most drives support this format. 678.It extphys 679Print out the list in extended physical sector format. 680The extended format allows for ranges of blocks to be printed. 681.El 682.It Fl G 683Print out the grown defect list. 684This is a list of bad blocks that have 685been remapped since the disk left the factory. 686.It Fl P 687Print out the primary defect list. 688This is the list of defects that were present in the factory. 689.It Fl q 690When printing status information with 691.Fl s , 692only print the number of defects. 693.It Fl s 694Just print the number of defects, not the list of defects. 695.It Fl S Ar offset 696Specify the starting offset into the defect list. 697This implies using the 698.Tn SCSI 699READ DEFECT DATA (12) command, as the 10 byte version of the command 700doesn't support the address descriptor index field. 701Not all drives support the 12 byte command, and some drives that support 702the 12 byte command don't support the address descriptor index field. 703.It Fl X 704Print out defects in hexadecimal (base 16) form instead of base 10 form. 705.El 706.Pp 707If neither 708.Fl P 709nor 710.Fl G 711is specified, 712.Nm 713will print out the number of defects given in the READ DEFECT DATA header 714returned from the drive. 715Some drives will report 0 defects if neither the primary or grown defect 716lists are requested. 717.It Ic modepage 718Allows the user to display and optionally edit a SCSI mode page. 719The mode 720page formats are located in 721.Pa /usr/share/misc/scsi_modes . 722This can be overridden by specifying a different file in the 723.Ev SCSI_MODES 724environment variable. 725The 726.Ic modepage 727command takes several arguments: 728.Bl -tag -width 12n 729.It Fl 6 730Use 6 byte MODE commands instead of default 10 byte. 731Old devices may not support 10 byte MODE commands, while new devices may 732not be able to report all mode pages with 6 byte commands. 733If not specified, 734.Nm 735starts with 10 byte commands and falls back to 6 byte on error. 736.It Fl d 737Disable block descriptors for mode sense. 738.It Fl D 739Display/edit block descriptors instead of mode page. 740.It Fl L 741Use long LBA block descriptors. 742Allows number of LBAs bigger then 2^^32. 743.It Fl b 744Displays mode page data in binary format. 745.It Fl e 746This flag allows the user to edit values in the mode page. 747The user may 748either edit mode page values with the text editor pointed to by his 749.Ev EDITOR 750environment variable, or supply mode page values via standard input, using 751the same format that 752.Nm 753uses to display mode page values. 754The editor will be invoked if 755.Nm 756detects that standard input is terminal. 757.It Fl l 758Lists all available mode pages. 759If specified more then once, also lists subpages. 760.It Fl m Ar page[,subpage] 761This specifies the number of the mode page and optionally subpage the user 762would like to view and/or edit. 763This argument is mandatory unless 764.Fl l 765is

2238device, but underneath, the drive reads and writes the bulk of its capacity 2239using SMR zones. 2240Sequential writes will yield better performance, but writing sequentially 2241is not required. 2242.It Host Aware 2243Host Aware drives expose the underlying zone layout via 2244.Tn SCSI 2245or 2246.Tn ATA 2247commands and allow the host to manage the zone conditions. 2248The host is not required to manage the zones on the drive, though. 2249Sequential writes will yield better performance in Sequential Write 2250Preferred zones, but the host can write randomly in those zones. 2251.It Host Managed 2252Host Managed drives expose the underlying zone layout via 2253.Tn SCSI 2254or 2255.Tn ATA 2256commands. 2257The host is required to access the zones according to the rules described 2258by the zone layout. 2259Any commands that violate the rules will be returned with an error. 2260.El 2261.Pp 2262SMR drives are divided into zones (typically in the range of 256MB each) 2263that fall into three general categories: 2264.Bl -tag -width 20n 2265.It Conventional 2266These are also known as Non Write Pointer zones. 2267These zones can be randomly written without an unexpected performance penalty. 2268.It Sequential Preferred 2269These zones should be written sequentially starting at the write pointer 2270for the zone. 2271They may be written randomly. 2272Writes that do not conform to the zone layout may be significantly slower 2273than expected. 2274.It Sequential Required 2275These zones must be written sequentially. 2276If they are not written sequentially,

2923.Sh HISTORY 2924The 2925.Nm 2926utility first appeared in 2927.Fx 3.0 . 2928.Pp 2929The mode page editing code and arbitrary SCSI command code are based upon 2930code in the old 2931.Xr scsi 8 2932utility and 2933.Xr scsi 3 2934library, written by Julian Elischer and Peter Dufault. 2935The 2936.Xr scsi 8 2937program first appeared in 2938.Bx 386 0.1.2.4 , 2939and first appeared in 2940.Fx 2941in 2942.Fx 2.0.5 . 2943.Sh AUTHORS 2944.An Kenneth Merry Aq Mt ken@FreeBSD.org 2945.Sh BUGS 2946The code that parses the generic command line arguments does not know that 2947some of the subcommands take multiple arguments. 2948So if, for instance, you 2949tried something like this: 2950.Bd -literal -offset indent 2951camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v 2952.Ed 2953.Pp 2954The sense information from the test unit ready command would not get 2955printed out, since the first 2956.Xr getopt 3 2957call in 2958.Nm 2959bails out when it sees the second argument to 2960.Fl c 2961(0x00), 2962above. 2963Fixing this behavior would take some gross code, or changes to the 2964.Xr getopt 3 2965interface. 2966The best way to circumvent this problem is to always make sure 2967to specify generic 2968.Nm 2969arguments before any command-specific arguments. 2970
