       sg_inq [-36] [-a] [-A] [-b] [--B=0|1] [-c] [-cl]	[-d]  [-e]  [-f]  [-h]
       [-H]  [-i]  [-I=FN]  [-l=LEN] [-L] [-m] [-M] [-o] [-p=VPD_PG] [-P] [-r]
       [-s] [-u] [-v] [-V] [-x]	[-36] [-?] DEVICE

       This utility, when DEVICE is given, sends a SCSI	INQUIRY	command	to  it
       then  outputs  the response. All	SCSI devices are meant to respond to a
       "standard" INQUIRY command with at least	a 36 byte response (in SCSI  2
       and  higher). An	INQUIRY	is termed as "standard"	when both the EVPD and
       CmdDt (now obsolete) bits are clear.

       Alternatively the --inhex=FN option can be given. In this  case	FN  is
       assumed	to be a	file name ('-' for stdin) containing ASCII hexadecimal
       representing an INQUIRY response.

       This utility supports two command line syntaxes.	The preferred  one  is
       shown  first  in	the synopsis and is described in the main OPTIONS sec-
       tion. A later section titled OLDER COMMAND LINE OPTIONS	describes  the
       second group of options.

       An  important  "non-standard" INQUIRY page is the Device	Identification
       Vital Product Data (VPD)	page [0x83]. Since  SPC-3,  support  for  this
       page  is	mandatory. The --id option decodes this	page. New VPD page in-
       formation is no longer being added to this utility. To get  information
       on new VPD pages	see the	sg_vpd(8) or sdparm(8) utilities.

       In Linux, if the	DEVICE exists and the SCSI INQUIRY fails (e.g. because
       the SG_IO ioctl is not supported) then an ATA IDENTIFY (PACKET)	DEVICE
       is tried. If it succeeds	then device identification strings are output.
       The --raw and --hex options can be used to manipulate the  output.   If
       the  --ata  option  is given then the SCSI INQUIRY is not performed and
       the DEVICE is assumed to	be ATA (or ATAPI). For	more  information  see
       the ATA DEVICES section below.

       In  some	operating systems a NVMe device	(e.g. SSD) may be given	as the
       DEVICE. For more	information see	the NVME DEVICES section below.

       The reference document used for interpreting an INQUIRY is T10/BSR  IN-
       CITS  502  Revision  19	which  is draft	SPC-5 revision 19, 14 February
       2018). It can be	found at .  Obsolete	 and  reserved
       items  in  the standard INQUIRY response	output are displayed in	square

       Arguments to long options are mandatory for short options as well.  The
       options	are  arranged  in  alphabetical	order based on the long	option

       -a, --ata
	      Assume given DEVICE is an	ATA or ATAPI device which can  receive
	      ATA  commands  from the host operating system. Skip the SCSI IN-
	      QUIRY command and	use either the	ATA  IDENTIFY  DEVICE  command
	      (for  non-packet devices)	or the ATA IDENTIFY PACKET DEVICE com-
	      mand. To show the	response in hex,  add  a  '--verbose'  option.
	      This option is only available in Linux.

       -B, --block=0|1
	      this  option  controls  how  the	file  handle  to the DEVICE is
	      opened. If this argument is 0 then the open is non-blocking.  If
	      the  argument  is	 1  then  the  open  is	 blocking.  In	Unix a
	      non-blocking open	is indicated by	 a  O_NONBLOCK	flag  while  a
	      blocking	open is	indicated by the absence of that flag. The de-
	      fault value depends on the operating system and the type of  DE-
	      VICE node. For Linux pass-throughs (i.e. the sg and bsg drivers)
	      the default is 0.

       -c, --cmddt
	      set the Command Support Data (CmdDt) bit (defaults to clear(0)).
	      Used in conjunction with the --page=PG option where PG specifies
	      the SCSI command opcode to query.	When used twice	 (e.g.	'-cc')
	      this  utility forms a list by looping over all 256 opcodes (0 to
	      255 inclusive) only outputting a	line  for  commands  that  are
	      found.  The  CmdDt  bit is now obsolete; it has been replaced by
	      the REPORT SUPPORTED OPERATION CODES  command,  see  the	sg_op-
	      codes(8) utility.

       -d, --descriptors
	      decodes  and  prints the version descriptors found in a standard
	      INQUIRY response.	There are up to	8 of them. Version descriptors
	      indicate	which  versions	 of standards and/or drafts the	DEVICE
	      complies with. The normal	components of a	standard  INQUIRY  are
	      output  (typically from the first	36 bytes of the	response) fol-
	      lowed by the version descriptors if any.

       -e     see entry	below for --vpd.

       -f, --force
	      As a sanity check, the normal action  when  fetching  VPD	 pages
	      other  than page 0x0 (the	"Supported VPD pages" VPD page), is to
	      first fetch page 0x0 and only if the requested page  is  one  of
	      the supported pages, to go ahead and fetch the requested page.
	      When  this option	is given, skip checking	of VPD page 0x0	before
	      accessing	the requested VPD page.	The prior check	 of  VPD  page
	      0x0 is known to crash certain USB	devices, so use	with care.

       -u, --export
	      prints  out information obtained from the	device.	The output can
	      be modified by selecting a VPD page with PG (from	--page=PG). If
	      the  device  identification VPD page 0x83	is given it prints out
	      information in the form: "SCSI_IDENT_<assoc>_<type>=<ident>"  to
	      stdout.  If  the	device serial number VPD page 0x80 is given it
	      prints out information in	the form: "SCSI_SERIAL=<ident>". Other
	      VPD  pages  are not supported. If	no VPD page is given it	prints
	      out   information	  in   the    form:    "SCSI_VENDOR=<vendor>",
	      "SCSI_MODEL=<model>",  and "SCSI_REVISION=<rev>",	taken from the
	      standard inquiry.	This may be useful for tools like  udev(7)  in

       -E, -x, --extended
	      prints the extended INQUIRY VPD page [0x86].

       -h, --help
	      print  out  the  usage message then exit.	When used twice, after
	      the usage	message, there is a list  of  available	 abbreviations
	      than can be given	to the --page=PG option.

       -H, --hex
	      rather  than  decode  a standard INQUIRY response, a VPD page or
	      command support data; print out the response in hex and send the
	      output  to  stdout.   Error  messages and	warnings are typically
	      output to	stderr.	When used twice	with the ATA  Information  VPD
	      page  [0x89]  decodes the	start of the response then outputs the
	      ATA IDENTIFY (PACKET) DEVICE response in hexadecimal bytes  (not
	      16  bit  words).	When used three	times with the ATA Information
	      VPD page [0x89] or the --ata option, this	 utility  outputs  the
	      ATA IDENTIFY (PACKET) DEVICE response in hexadecimal words suit-
	      able for input to	'hdparm	--Istdin'.  See	note below.
	      To generate output suitable for placing in a file	 that  can  be
	      used  by	a later	invocation with	the --inhex=FN option, use the
	      '-HHHH'  option  (e.g.  'sg_inq	-p   di	  -HHHH	  /dev/sg3   >

       -i, --id
	      prints the device	identification VPD page	[0x83].

       -I, --inhex=FN
	      FN  is  expected to be a file name (or '-' for stdin) which con-
	      tains ASCII hexadecimal or binary	representing an	 INQUIRY  (in-
	      cluding  VPD  page) response. This utility will then decode that
	      response.	It is preferable to also supply	the --page=PG  option,
	      if  not  this  utility  will attempt to guess which VPD page (or
	      standard INQUIRY)	that the  response  is	associated  with.  The
	      hexadecimal  should  be arranged as 1 or 2 digits	representing a
	      byte each	of which is whitespace or  comma  separated.  Anything
	      from  and	including a hash mark to the end of a line is ignored.
	      If the --raw option is also given	then FN	is treated as binary.

       -l, --len=LEN
	      the number LEN is	the "allocation	length"	field in  the  INQUIRY
	      cdb.   This  is the (maximum) length of the response returned by
	      the device. The default value of LEN is 0	which  is  interpreted
	      as:  first  request is for 36 bytes and if necessary execute an-
	      other INQUIRY if the "additional length" field in	 the  response
	      indicates	that more than 36 bytes	is available.
	      If  LEN  is greater than 0 then only one INQUIRY command is per-
	      formed.  This means that the Serial Number  (obtained  from  the
	      Serial  Number VPD pgae (0x80)) is not fetched and therefore not
	      printed.	See the	NOTES section below about "36 byte INQUIRYs".

       -L, --long
	      this option causes more information to be	decoded	from the Iden-
	      tify command sent	to a NVMe DEVICE.

       -m, --maxlen=LEN
	      this  option  has	the same action	as the --len=LEN option	above.
	      It has been added	for compatibility with	the  sg_vpd,  sg_modes
	      and sg_logs utilities.

       -O, --old
	      Switch to	older style options. Please use	as first option	on the
	      command line.

       -o, --only
	      Do not attempt to	additionally retrieve the  serial  number  VPD
	      page (0x80) to enhance the output	of a standard INQUIRY. So with
	      this option given	and no others, this utility will send a	 stan-
	      dard INQUIRY SCSI	command	and decode its response. No other SCSI
	      commands will be sent to the DEVICE.  Without this option	an ad-
	      ditional	SCSI command is	sent: a	(non-standard) SCSI INQUIRY to
	      fetch the	Serial Number VPD page.	However	the Serial Number  VPD
	      page  is	not mandatory (while the Device	Identification page is
	      mandatory	but a billion USB keys ignore that) and	may cause nui-
	      sance error reports.
	      For NVMe devices only the	Identify controller is performed, even
	      if the DEVICE includes a namespace identifier.  For  example  in
	      FreeBSD given a DEVICE named /dev/nvme0ns1 then an Identify con-
	      troller is sent to /dev/nvme0 and	nothing	is sent	to  its	 "ns1"
	      (first namespace).

       -p, --page=PG
	      the  PG argument can be either a number of an abbreviation for a
	      VPD page.	To enumerate the available abbreviations for VPD pages
	      use  '-hh'  or  a	bad abbreviation (e.g, '--page=xxx'). When the
	      --cmddt option is	given (once) then PG is	interpreted as an  op-
	      code number (so VPD page abbreviations make little sense).
	      If  PG  is  a  negative  number, then a standard INQUIRY is per-
	      formed. This can be used to override some	guessing logic associ-
	      ated with	the --inhex=FN option.
	      If  PG  is not found in the 'Supported VPD pages'	VPD page (0x0)
	      then EDOM	is returned. To	bypass this check use the --force  op-

       -r, --raw
	      in  the absence of --inhex=FN then the output response is	in bi-
	      nary.  The output	should be piped	to a file or  another  utility
	      when  this option	is used. The binary is sent to stdout, and er-
	      rors are sent to stderr.
	      If used with --inhex=FN then the contents	of FN  is  treated  as

       -s, --vendor
	      output a standard	INQUIRY	response's vendor specific fields from
	      offset 36	to 55 in ASCII.	When used twice	(i.e. '-ss') also out-
	      put  the	vendor specific	field from offset 96 in	ASCII. This is
	      only done	if the data passes some	simple sanity checks.

       -v, --verbose
	      increase level of	verbosity. Can be used multiple	times.

       -V, --version
	      print out	version	string then exit.

       -e, --vpd
	      set the Enable  Vital  Product  Data  (EVPD)  bit	 (defaults  to
	      clear(0)).  Used	in conjunction with the	--page=PG option where
	      PG specifies the VPD page	number to query. If the	 --page=PG  is
	      not  given  then PG defaults to zero which is the	"Supported VPD
	      pages" VPD page. A more up to date decoding of VPD pages can  be
	      found in the sg_vpd(8) utility.

       Some  devices  with  weak SCSI command set implementations lock up when
       they receive commands they don't	understand (and	some lock up  if  they
       receive	response lengths that they don't expect). Such devices need to
       be treated carefully, use the '--len=36'	option.	 Without  this	option
       this utility will issue an initial standard INQUIRY requesting 36 bytes
       of response data. If the	device indicates it could have	supplied  more
       data then a second INQUIRY is issued to fetch the longer	response. That
       second command may lock up faulty devices.

       ATA or ATAPI devices that use a SCSI to ATA Translation layer (see  SAT
       at may support the SCSI ATA	INFORMATION VPD	page. This re-
       turns the IDENTIFY (PACKET) DEVICE response amongst other things.   The
       ATA Information VPD page	can be fetched with '--page=ai'.

       In  the INQUIRY standard	response there is a 'MultiP' flag which	is set
       when the	device has 2 or	more ports. Some  vendors  use	the  preceding
       vendor  specific	('VS') bit to indicate which port is being accessed by
       the INQUIRY command (0 -> relative port 1 (port	"a"),  1  ->  relative
       port 2 (port "b")). When	the 'MultiP' flag is set, the preceding	vendor
       specific	bit is shown in	parentheses. SPC-3  compliant  devices	should
       use the device identification VPD page (0x83) to	show which port	is be-
       ing used	for access and the SCSI	ports VPD  page	 (0x88)	 to  show  all
       available ports on the device.

       In  the	2.4  series of Linux kernels the DEVICE	must be	a SCSI generic
       (sg) device. In the 2.6 series and later	block devices (e.g.  disks and
       ATAPI  DVDs)  can also be specified. For	example	"sg_inq	/dev/sda" will
       work in the 2.6 series kernels. From lk 2.6.6 other SCSI	"char"	device
       names may be used as well (e.g. "/dev/st0m").

       The number of bytes output by --hex and --raw is	36 bytes or the	number
       given to	--len=LEN (or --maxlen=LEN). That number  is  reduced  if  the
       "resid"	returned  by  the HBA indicates	less bytes were	sent back from

       The DEVICE is opened with a read-only  flag  (e.g.  in  Unix  with  the
       O_RDONLY	flag).

       There  are two major types of ATA devices: non-packet devices (e.g. ATA
       disks) and packet devices (ATAPI). The majority of  ATAPI  devices  are
       CD/DVD/BD drives	in which the ATAPI transport carries the MMC set (i.e.
       a SCSI command set). Further, both types	of ATA	devices	 can  be  con-
       nected  to a host computer via a	"SCSI" (or some	other) transport. When
       an ATA disk is controlled via a SCSI (or	non-ATA)  transport  then  two
       approaches  are	commonly used: tunnelling (e.g.	STP in Serial Attached
       SCSI (SAS)) or by emulating a SCSI device (e.g.	with  a	 SCSI  to  ATA
       translation  layer,  see	 SAT  at ).	Even when the physical
       transport to the	host computer is ATA (especially in the	case of	 SATA)
       the  operating  system  may  choose  to	put  a SAT layer in the	driver
       "stack" (e.g. libata in Linux).

       The main	identifying command for	any SCSI device	 is  an	 INQUIRY.  The
       corresponding  command  for an ATA non-packet device is IDENTIFY	DEVICE
       while for an ATA	packet device it is IDENTIFY PACKET DEVICE.

       When this utility is invoked for	an  ATAPI  device  (e.g.  a  CD/DVD/BD
       drive with "sg_inq /dev/hdc") then a SCSI INQUIRY is sent to the	device
       and if it responds then the response to decoded	and  output  and  this
       utility	exits.	To  see	the response for an ATA	IDENTIFY PACKET	DEVICE
       command add the --ata option (e.g. "sg_inq --ata	/dev/hdc).

       This utility doesn't decode the response	to an  ATA  IDENTIFY  (PACKET)
       DEVICE  command,	 hdparm	does a good job	at that. The '-HHH' option has
       been added for use with either the '--ata'  or  '--page=ai'  option  to
       produce	a format acceptable to "hdparm --Istdin".  An example: 'sg_inq
       --ata -HHH /dev/hdc | hdparm --Istdin'. See hdparm.

       Currently these device are typically SSDs (Solid	State Disks)  directly
       connected  to a PCIe connector or via a specialized connector such as a
       M2 connector. Linux and FreeBSD treat NVMe storage devices as  separate
       from  SCSI  storage  with device	names like /dev/nvme0n1	(in Linux) and
       /dev/nvme0ns1 (in FreeBSD). The NVM Express group has a document	titled
       "NVM Express: SCSI Translation Reference" which defines a partial "SCSI
       to NVMe Translation Layer" often	known by its acronym: SNTL.

       On operating systems where it is	supported by this package, this	 util-
       ity  will  detect  NVMe	storage	devices	directly connected and send an
       Identify	controller NVMe	Admin command and decode its response. A  NVMe
       controller  is  architecturally similar to a SCSI target	device.	If the
       NVMe DEVICE indicates a namespace then an Identify namespace NVMe Admin
       command	is  sent  to that namespace and	its response is	decoded. Name-
       spaces are numbered sequentially	starting from 1. Namespaces are	 simi-
       lar to SCSI Logical Units and their identifiers (nsid_s)	can be thought
       of as SCSI LUNs.	In the Linux and FreeBSD example  device  names	 above
       the "n1"	and the	"ns1" parts indicate nsid 1 . If no namespace is given
       in the DEVICE then all namespaces found	in  the	 controller  are  sent
       Identify	namespace commands and the responses are decoded.

       To  get more details in the response use	the --long option. To only get
       the controller's	Identify decoded use the --only	option.

       It is possible that even	though the DEVICE presents as a	 NVMe  device,
       it  has	a  SNTL	and accepts SCSI commands. In this case	to send	a SCSI
       INQUIRY command (and fetch its VPD pages) use 'sg_vpd  -p  sinq	<dev>'
       (or to get VPD pages: 'sg_vpd -p	<vpd_page> <dev>').

       The exit	status of sg_inq is 0 when it is successful. Otherwise see the
       sg3_utils(8) man	page.

       The options in this section were	 the  only  ones  available  prior  to
       sg3_utils  version 1.23 . Since then this utility defaults to the newer
       command line options which can be overridden by using --old (or -O)  as
       the first option. See the ENVIRONMENT VARIABLES section for another way
       to force	the use	of these older command line options.

       -36    only requests 36 bytes of	response data for an INQUIRY. Further-
	      more  even if the	device indicates in its	response it can	supply
	      more data, a second (longer) INQUIRY is not performed. This is a
	      paranoid	setting.  Equivalent to	'--len=36' in the OPTIONS sec-

       -a     fetch  the  ATA  Information  VPD	 page  [0x89].	Equivalent  to
	      '--page=ai'  in the OPTIONS section. This	page is	defined	in SAT
	      (see at

       -A     Assume given DEVICE is an	ATA or ATAPI  device.	Equivalent  to
	      --ata in the OPTIONS section.

       -b     decodes  the  Block  Limits  VPD	page  [0xb0].	Equivalent  to
	      '--page=bl' in the OPTIONS section.  This	 page  is  defined  in
	      SBC-2 (see and later.

       -B=0|1 equivalent to --block=0|1	in OPTIONS section.

       -c     set the Command Support Data (CmdDt) bit (defaults to clear(0)).
	      Used in conjunction with the -p=VPD_PG  option  to  specify  the
	      SCSI  command  opcode to query. Equivalent to --cmddt in the OP-
	      TIONS section.

       -cl    lists the	command	data for all supported commands	 (followed  by
	      the  command  name) by looping through all 256 opcodes. This op-
	      tion uses	the CmdDt bit which is now obsolete.  See  the	sg_op-
	      codes(8)	utility.   Equivalent  to '--cmddt --cmddt' in the OP-
	      TIONS section.

       -d     decodes depending	on context. If -e option is given, or any  op-
	      tion  that  implies -e (e.g. '-i'	or '-p=80'), then this utility
	      attempts to decode the indicated VPD page.  Otherwise  the  ver-
	      sion  descriptors	 (if  any) are listed following	a standard IN-
	      QUIRY response. In the version descriptors sense,	equivalent  to
	      --descriptors in the OPTIONS section.

       -e     enable  (i.e.  sets) the Vital Product Data (EVPD) bit (defaults
	      to clear(0)).  Used in conjunction with the -p=VPD_PG option  to
	      specify  the  VPD	 page to fetch.	If -p=VPD_PG is	not given then
	      VPD page 0 (list supported VPD pages) is assumed.

       -f     Equivalent to --force in the OPTIONS section.

       -h     outputs INQUIRY response in hex rather than trying to decode it.
	      Equivalent to --hex in the OPTIONS section.

       -H     same action as -h.  Equivalent to	--hex in the OPTIONS section.

       -i     decodes the Device Identification	VPD page [0x83]. Equivalent to
	      --id in the OPTIONS section. This	page is	 made  up  of  several
	      "designation  descriptors".  If -h is given then each descriptor
	      header is	decoded	and the	identifier itself is output in hex. To
	      see the whole VPD	0x83 page response in hex use '-p=83 -h'.

       -I=FN  equivalent to --inhex=FN in the OPTIONS section.

       -l=LEN equivalent to --len=LEN in the OPTIONS section.

       -L     equivalent to --long in the OPTIONS section.

       -m     decodes the Management network addresses VPD page	[0x85].	Equiv-
	      alent to '--page=mna' in the OPTIONS section.

       -M     decodes the Mode page policy VPD	page  [0x87].	Equivalent  to
	      '--page=mpp' in the OPTIONS section.

       -N, --new
	      Switch to	the newer style	options.

       -o     equivalent to --only in the OPTIONS section.

	      used  in	conjunction with the -e	or -c option. If neither given
	      then the -e option assumed. When the -e option is	also given (or
	      assumed)	then  the argument to this option is the VPD page num-
	      ber.  The	argument is interpreted	as hexadecimal and is expected
	      to be in the range 0 to ff inclusive. Only VPD page 0 is decoded
	      and it lists supported VPD pages and their names (if known).  To
	      decode  the  mandatory device identification page	(0x83) use the
	      -i option. A now obsolete	usage is when the -c option  is	 given
	      in  which	 case  the  argument to	this option is assumed to be a
	      command opcode number. Recent SCSI draft	standards  have	 moved
	      this  facility  to  a  separate command (see sg_opcodes(8)). De-
	      faults to	0 so if	-e is given without this option	then VPD  page
	      0	is output.

       -P     decodes  the  Unit Path Report VPD page [0xc0] which is EMC spe-
	      cific.  Equivalent to '--page=upr' in the	OPTIONS	section.

       -r     outputs the response in binary to	stdout.	 Equivalent  to	 --raw
	      in  the  OPTIONS	section.   Can	be used	twice (i.e. '-rr' (and
	      '-HHH' has same effect)) and if used with	the -A	or  -a	option
	      yields output with the same format as "cat /proc/ide/hd<x>/iden-
	      tify" so that it can then	be piped to "hdparm --Istdin".

       -s     decodes  the  SCSI  Ports	 VPD  page  [0x88].    Equivalent   to
	      '--page=sp' in the OPTIONS section.

       -u     equivalent to '--export' in the OPTIONS section.

       -v     increase level of	verbosity. Can be used multiple	times.

       -V     print out	version	string then exit.

       -x     decodes  the  Extended INQUIRY data VPD [0x86] page.  Equivalent
	      to '--page=ei' in	the OPTIONS section.

       -?     output usage message and exit. Ignore all	other parameters.

       The examples in this page use Linux device names. For  suitable	device
       names  in  other	 supported  Operating Systems see the sg3_utils(8) man

       To view the standard inquiry response use without options:

	  sg_inq /dev/sda

       Some SCSI devices include version descriptors  indicating  the  various
       SCSI standards and drafts they support. They can	be viewed with:

	  sg_inq -d /dev/sda

       Modern  SCSI devices include Vital Product Data (VPD)pages which	can be
       viewed with the SCSI INQUIRY command. To	list the supported  VPD	 pages
       (but not	their contents)	try:

	  sg_inq -e /dev/sda

       Some  VPD pages can be read with	the sg_inq utility but a newer utility
       called sg_vpd specializes in showing their contents. The	sdparm utility
       can also	be used	to show	the contents of	VPD pages.

       Further	examples  of  sg_inq  together with some typical output	can be
       found on web page.

       Since	sg3_utils    version	1.23	the    environment    variable
       SG3_UTILS_OLD_OPTS  can	be given. When it is present this utility will
       expect the older	command	line options. So the presence of this environ-
       ment variable is	equivalent to using --old (or -O) as the first command
       line option.
