Even expert users are encouraged to exercise caution when using this command. Novice users should stay away from this utility. .Pp The .Nm utility has a number of primary functions, many of which support an optional device identifier. A device identifier can take one of three forms: .Bl -tag -width 14n .It deviceUNIT Specify a device name and unit number combination, like "da5" or "cd3". Note that character device node names (e.g. /dev/da0) are .Em not allowed here. .It bus:target Specify a bus number and target id. The bus number can be determined from the output of .Dq camcontrol devlist . The lun defaults to 0. .It bus:target:lun Specify the bus, target and lun for a device. (e.g. 1:2:0) .El .Pp The device identifier, if it is specified, .Em must come immediately after the function name, and before any generic or function-specific arguments. Note that the .Fl n and .Fl u arguments described below will override any device name or unit number specified beforehand. The .Fl n and .Fl u arguments will .Em not override a specified bus:target or bus:target:lun, however. .Pp Most of the .Nm primary functions support these generic arguments: .Bl -tag -width 14n .It Fl C Ar count SCSI command retry count. In order for this to work, error recovery .Pq Fl E must be turned on. .It Fl E Instruct the kernel to perform generic SCSI error recovery for the given command. This is needed in order for the retry count .Pq Fl C to be honored. Other than retrying commands, the generic error recovery in the code will generally attempt to spin up drives that are not spinning. It may take some other actions, depending upon the sense code returned from the command. .It Fl n Ar dev_name Specify the device type to operate on, e.g. "da", "cd". .It Fl t Ar timeout SCSI command timeout in seconds. This overrides the default timeout for any given command. .It Fl u Ar unit_number Specify the device unit number, e.g. "1", "5". .It Fl v Be verbose, print out sense information for failed SCSI commands. .El .Pp Primary command functions: .Bl -tag -width periphlist .It Ic devlist List all physical devices (logical units) attached to the CAM subsystem. This also includes a list of peripheral drivers attached to each device. With the .Fl v argument, SCSI bus number, adapter name and unit numbers are printed as well. .It Ic periphlist List all peripheral drivers attached to a given physical device (logical unit). .It Ic tur Send the SCSI test unit ready (0x00) command to the given device. The .Nm utility will report whether the device is ready or not. .It Ic inquiry Send a SCSI inquiry command (0x12) to a device. By default, .Nm will print out the standard inquiry data, device serial number, and transfer rate information. The user can specify that only certain types of inquiry data be printed: .Bl -tag -width 4n .It Fl D Get the standard inquiry data. .It Fl S Print out the serial number. If this flag is the only one specified, .Nm will not print out "Serial Number" before the value returned by the drive. This is to aid in script writing. .It Fl R Print out transfer rate information. .El .It Ic start Send the SCSI Start/Stop Unit (0x1B) command to the given device with the start bit set. .It Ic stop Send the SCSI Start/Stop Unit (0x1B) command to the given device with the start bit cleared. .It Ic eject Send the SCSI Start/Stop Unit (0x1B) command to the given device with the start bit cleared and the eject bit set. .It Ic rescan Tell the kernel to scan all busses in the system (with the .Ar all argument), the given bus (XPT_SCAN_BUS), or bus:target:lun (XPT_SCAN_LUN) for new devices or devices that have gone away. The user may specify a scan of all busses, a single bus, or a lun. Scanning all luns on a target isn't supported. .It Ic reset Tell the kernel to reset all busses in the system (with the .Ar all argument) or the given bus (XPT_RESET_BUS) by issuing a SCSI bus reset for that bus, or to reset the given bus:target:lun (XPT_RESET_DEV), typically by issuing a BUS DEVICE RESET message after connecting to that device. Note that this can have a destructive impact on the system. .It Ic defects Send the SCSI READ DEFECT DATA (10) command (0x37) to the given device, and print out any combination of: the total number of defects, the primary defect list (PLIST), and the grown defect list (GLIST). .Bl -tag -width 11n .It Fl f Ar format The three format options are: .Em block , to print out the list as logical blocks, .Em bfi , to print out the list in bytes from index format, and .Em phys , to print out the list in physical sector format. The format argument is required. Most drives support the physical sector format. Some drives support the logical block format. Many drives, if they don't support the requested format, return the data in an alternate format, along with sense information indicating that the requested data format isn't supported. The .Nm utility attempts to detect this, and print out whatever format the drive returns. If the drive uses a non-standard sense code to report that it doesn't support the requested format, .Nm will probably see the error as a failure to complete the request. .It Fl G Print out the grown defect list. This is a list of bad blocks that have been remapped since the disk left the factory. .It Fl P Print out the primary defect list. .El .Pp If neither .Fl P nor .Fl G is specified, .Nm will print out the number of defects given in the READ DEFECT DATA header returned from the drive. .It Ic modepage Allows the user to display and optionally edit a SCSI mode page. The mode page formats are located in .Pa /usr/share/misc/scsi_modes . This can be overridden by specifying a different file in the .Ev SCSI_MODES environment variable. The .Ic modepage command takes several arguments: .Bl -tag -width 12n .It Fl d Disable block descriptors for mode sense. .It Fl e This flag allows the user to edit values in the mode page. .It Fl m Ar mode_page This specifies the number of the mode page the user would like to view and/or edit. This argument is mandatory. .It Fl P Ar pgctl This allows the user to specify the page control field. Possible values are: .Bl -tag -width xxx -compact .It 0 Current values .It 1 Changeable values .It 2 Default values .It 3 Saved values .El .El .It Ic cmd Allows the user to send an arbitrary SCSI CDB to any device. The .Ic cmd function requires the .Fl c argument to specify the CDB. Other arguments are optional, depending on the command type. The command and data specification syntax is documented in .Xr cam_cdbparse 3 . NOTE: If the CDB specified causes data to be transfered to or from the SCSI device in question, you MUST specify either .Fl i or .Fl o . .Bl -tag -width 17n .It Fl c Ar cmd Op args This specifies the SCSI CDB. CDBs may be 6, 10, 12 or 16 bytes. .It Fl i Ar len Ar fmt This specifies the amount of data to read, and how it should be displayed. If the format is .Sq - , .Ar len bytes of data will be read from the device and written to standard output. .It Fl o Ar len Ar fmt Op args This specifies the amount of data to be written to a device, and the data that is to be written. If the format is .Sq - , .Ar len bytes of data will be read from standard input and written to the device. .El .It Ic debug Turn on CAM debugging printfs in the kernel. This requires options CAMDEBUG in your kernel config file. WARNING: enabling debugging printfs currently causes an EXTREME number of kernel printfs. You may have difficulty turning off the debugging printfs once they start, since the kernel will be busy printing messages and unable to service other requests quickly. The .Ic debug function takes a number of arguments: .Bl -tag -width 18n .It Fl I Enable CAM_DEBUG_INFO printfs. +.It Fl P +Enable CAM_DEBUG_PERIPH printfs. .It Fl T Enable CAM_DEBUG_TRACE printfs. .It Fl S Enable CAM_DEBUG_SUBTRACE printfs. +.It Fl X +Enable CAM_DEBUG_XPT printfs. .It Fl c Enable CAM_DEBUG_CDB printfs. This will cause the kernel to print out the SCSI CDBs sent to the specified device(s). .It all Enable debugging for all devices. .It off Turn off debugging for all devices .It bus Ns Op :target Ns Op :lun Turn on debugging for the given bus, target or lun. If the lun or target and lun are not specified, they are wildcarded. (i.e., just specifying a bus turns on debugging printfs for all devices on that bus.) .El .It Ic tags Show or set the number of "tagged openings" or simultaneous transactions we attempt to queue to a particular device. By default, the .Ic tags command, with no command-specific arguments (i.e. only generic arguments) prints out the "soft" maximum number of transactions that can be queued to the device in question. For more detailed information, use the .Fl v argument described below. .Bl -tag -width 7n .It Fl N Ar tags Set the number of tags for the given device. This must be between the minimum and maximum number set in the kernel quirk table. The default for most devices that support tagged queueing is a minimum of 2 and a maximum of 255. The minimum and maximum values for a given device may be determined by using the .Fl v switch. The meaning of the .Fl v switch for this .Nm subcommand is described below. .It Fl q Be quiet, and don't report the number of tags. This is generally used when setting the number of tags. .It Fl v The verbose flag has special functionality for the .Em tags argument. It causes .Nm to print out the tagged queueing related fields of the XPT_GDEV_TYPE CCB: .Bl -tag -width 13n .It dev_openings This is the amount of capacity for transactions queued to a given device. .It dev_active This is the number of transactions currently queued to a device. .It devq_openings This is the kernel queue space for transactions. This count usually mirrors dev_openings except during error recovery operations when the device queue is frozen (device is not allowed to receive commands), the number of dev_openings is reduced, or transaction replay is occurring. .It devq_queued This is the number of transactions waiting in the kernel queue for capacity on the device. This number is usually zero unless error recovery is in progress. .It held The held count is the number of CCBs held by peripheral drivers that have either just been completed or are about to be released to the transport layer for service by a device. Held CCBs reserve capacity on a given device. .It mintags This is the current "hard" minimum number of transactions that can be queued to a device at once. The .Ar dev_openings value above cannot go below this number. The default value for .Ar mintags is 2, although it may be set higher or lower for various devices. .It maxtags This is the "hard" maximum number of transactions that can be queued to a device at one time. The .Ar dev_openings value cannot go above this number. The default value for .Ar maxtags is 255, although it may be set higher or lower for various devices. .El .El .It Ic negotiate Show or negotiate various communication parameters. Some controllers may not support setting or changing some of these values. For instance, the Adaptec 174x controllers do not support changing a device's sync rate or offset. The .Nm utility will not attempt to set the parameter if the controller indicates that it does not support setting the parameter. To find out what the controller supports, use the .Fl v flag. The meaning of the .Fl v flag for the .Ic negotiate command is described below. Also, some controller drivers don't support setting negotiation parameters, even if the underlying controller supports negotiation changes. Some controllers, such as the Advansys wide controllers, support enabling and disabling synchronous negotiation for a device, but do not support setting the synchronous negotiation rate. .Bl -tag -width 17n .It Fl a Attempt to make the negotiation settings take effect immediately by sending a Test Unit Ready command to the device. .It Fl c Show or set current negotiation settings. This is the default. .It Fl D Ar enable|disable Enable or disable disconnection. .It Fl O Ar offset Set the command delay offset. .It Fl q Be quiet, don't print anything. This is generally useful when you want to set a parameter, but don't want any status information. .It Fl R Ar syncrate Change the synchronization rate for a device. The sync rate is a floating point value specified in MHz. So, for instance, .Sq 20.000 is a legal value, as is .Sq 20 . .It Fl T Ar enable|disable Enable or disable tagged queueing for a device. .It Fl U Show or set user negotiation settings. The default is to show or set current negotiation settings. .It Fl v The verbose switch has special meaning for the .Ic negotiate subcommand. It causes .Nm to print out the contents of a Path Inquiry (XPT_PATH_INQ) CCB sent to the controller driver. .It Fl W Ar bus_width Specify the bus width to negotiate with a device. The bus width is specified in bits. The only useful values to specify are 8, 16, and 32 bits. The controller must support the bus width in question in order for the setting to take effect. .El .Pp In general, sync rate and offset settings will not take effect for a device until a command has been sent to the device. The .Fl a switch above will automatically send a Test Unit Ready to the device so negotiation parameters will take effect. .It Ic format Issue the .Tn SCSI FORMAT UNIT command to the named device. .Pp .Em WARNING! WARNING! WARNING! .Pp Low level formatting a disk will destroy ALL data on the disk. Use extreme caution when issuing this command. Many users low-level format disks that do not really need to be low-level formatted. There are relatively few scenarios that call for low-level formatting a disk. One reason for low-level formatting a disk is to initialize the disk after changing its physical sector size. Another reason for low-level formatting a disk is to revive the disk if you are getting "medium format corrupted" errors from the disk in response to read and write requests. .Pp Some disks take longer than others to format. Users should specify a timeout long enough to allow the format to complete. The default format timeout is 3 hours, which should be long enough for most disks. Some hard disks will complete a format operation in a very short period of time (on the order of 5 minutes or less). This is often because the drive doesn't really support the FORMAT UNIT command -- it just accepts the command, waits a few minutes and then returns it. .Pp The .Sq format subcommand takes several arguments that modify its default behavior. The .Fl q and .Fl y arguments can be useful for scripts. .Pp .Bl -tag -width 6n .It Fl q Be quiet, don't print any status messages. This option will not disable the questions, however. To disable questions, use the .Fl y argument, below. .It Fl w Issue a non-immediate format command. By default, .Nm issues the FORMAT UNIT command with the immediate bit set. This tells the device to immediately return the format command, before the format has actually completed. Then, .Nm gathers .Tn SCSI sense information from the device every second to determine how far along in the format process it is. If the .Fl w argument is specified, .Nm will issue a non-immediate format command, and will be unable to print any information to let the user know what percentage of the disk has been formatted. .It Fl y Don't ask any questions. By default, .Nm will ask the user if he/she really wants to format the disk in question, and also if the default format command timeout is acceptable. The user will not be asked about the timeout if a timeout is specified on the command line. .El .It Ic help Print out verbose usage information. .El .Sh ENVIRONMENT The .Ev SCSI_MODES variable allows the user to specify an alternate mode page format file. .Pp The .Ev EDITOR variable determines which text editor .Nm starts when editing mode pages. .Sh FILES .Bl -tag -width /usr/share/misc/scsi_modes -compact .It Pa /usr/share/misc/scsi_modes is the SCSI mode format database. .It Pa /dev/xpt0 is the transport layer device. .It Pa /dev/pass* are the CAM application passthrough devices. .El .Sh EXAMPLES .Dl camcontrol eject -n cd -u 1 -v .Pp Eject the CD from cd1, and print SCSI sense information if the command fails. .Pp .Dl camcontrol tur da0 .Pp Send the SCSI test unit ready command to da0. The .Nm utility will report whether the disk is ready, but will not display sense information if the command fails since the .Fl v switch was not specified. .Pp .Bd -literal -offset indent camcontrol tur da1 -E -C 4 -t 50 -v .Ed .Pp Send a test unit ready command to da1. Enable kernel error recovery. Specify a retry count of 4, and a timeout of 50 seconds. Enable sense printing (with the .Fl v flag) if the command fails. Since error recovery is turned on, the disk will be spun up if it is not currently spinning. The .Nm utility will report whether the disk is ready. .Bd -literal -offset indent camcontrol cmd -n cd -u 1 -v -c "3C 00 00 00 00 00 00 00 0e 00" \e -i 0xe "s1 i3 i1 i1 i1 i1 i1 i1 i1 i1 i1 i1" .Ed .Pp Issue a READ BUFFER command (0x3C) to cd1. Display the buffer size of cd1, and display the first 10 bytes from the cache on cd1. Display SCSI sense information if the command fails. .Pp .Bd -literal -offset indent camcontrol cmd -n cd -u 1 -v -c "3B 00 00 00 00 00 00 00 0e 00" \e -o 14 "00 00 00 00 1 2 3 4 5 6 v v v v" 7 8 9 8 .Ed .Pp Issue a WRITE BUFFER (0x3B) command to cd1. Write out 10 bytes of data, not including the (reserved) 4 byte header. Print out sense information if the command fails. Be very careful with this command, improper use may cause data corruption. .Pp .Bd -literal -offset indent camcontrol modepage da3 -m 1 -e -P 3 .Ed .Pp Edit mode page 1 (the Read-Write Error Recover page) for da3, and save the settings on the drive. Mode page 1 contains a disk drive's auto read and write reallocation settings, among other things. .Pp .Dl camcontrol rescan all .Pp Rescan all SCSI busses in the system for devices that have been added, removed or changed. .Pp .Dl camcontrol rescan 0 .Pp Rescan SCSI bus 0 for devices that have been added, removed or changed. .Pp .Dl camcontrol rescan 0:1:0 .Pp Rescan SCSI bus 0, target 1, lun 0 to see if it has been added, removed, or changed. .Pp .Dl camcontrol tags da5 -N 24 .Pp Set the number of concurrent transactions for da5 to 24. .Pp .Bd -literal -offset indent camcontrol negotiate -n da -u 4 -T disable .Ed .Pp Disable tagged queueing for da4. .Pp .Bd -literal -offset indent camcontrol negotiate -n da -u 3 -R 20.000 -O 15 -a .Ed .Pp Negotiate a sync rate of 20MHz and an offset of 15 with da3. Then send a Test Unit Ready command to make the settings take effect. .Sh SEE ALSO .Xr cam 3 , .Xr cam_cdbparse 3 , .Xr cam 4 , .Xr pass 4 , .Xr xpt 4 .Sh HISTORY The .Nm utility first appeared in .Fx 3.0 . .Pp The mode page editing code and arbitrary SCSI command code are based upon code in the old .Xr scsi 8 utility and .Xr scsi 3 library, written by Julian Elischer and Peter Dufault. The .Xr scsi 8 program first appeared in .Bx 386 0.1.2.4 , and first appeared in .Fx in .Fx 2.0.5 . .Sh AUTHORS .An Kenneth Merry Aq ken@FreeBSD.org .Sh BUGS The code that parses the generic command line arguments doesn't know that some of the subcommands take multiple arguments. So if, for instance, you tried something like this: .Bd -literal -offset indent camcontrol cmd -n da -u 1 -c "00 00 00 00 00 v" 0x00 -v .Ed .Pp The sense information from the test unit ready command would not get printed out, since the first .Xr getopt 3 call in .Nm bails out when it sees the second argument to .Fl c (0x00), above. Fixing this behavior would take some gross code, or changes to the .Xr getopt 3 interface. The best way to circumvent this problem is to always make sure to specify generic .Nm arguments before any command-specific arguments.

It doesn't quite work out that way. When * the first invocation of getopt finishes, it leaves optind pointing * to the argument _after_ the first argument in the second group. * So when the second invocation of getopt comes around, it doesn't * recognize the first argument it gets and then bails out. * * A nice alternative would be to have a flag for getopt that says * "just keep parsing arguments even when you encounter an unknown * argument", but there isn't one. So there's no real clean way to * easily parse two sets of arguments without having one invocation * of getopt know about the other. * * Without this hack, the first invocation of getopt would work as * long as the generic arguments are first, but the second invocation * (in the subfunction) would fail in one of two ways. In the case * where you don't set optreset, it would fail because optind may be * pointing to the argument after the one it should be pointing at. * In the case where you do set optreset, and reset optind, it would * fail because getopt would run into the first set of options, which * it doesn't understand. * * All of this would "sort of" work if you could somehow figure out * whether optind had been incremented one option too far.
