16 The scsi_inquiry structure contains 36 required bytes, followed by a
17 variable number of vendor-specific parameters. Bytes 59 through 95, if
18 returned, are reserved for future standardization. This structure is
19 part of scsi_device(9S) structure and typically filled in by
20 scsi_probe(9F).

60 inq_dtype identifies the type of device. Bits 0 - 4 represent the
64 Peripheral Device Type and bits 5 - 7 represent the Peripheral Quali‐
65 fier. The following values are appropriate for Peripheral Device Type
66 field:
67 DTYPE_DIRECT Direct-access device (for example, magnetic disk).
69 DTYPE_SEQUENTIAL Sequential-access device (for example, magnetic
72 tape).
73 DTYPE_PRINTER Printer device.
76 DTYPE_PROCESSOR Processor device.
79 DTYPE_WORM Write-once device (for example, some optical
82 disks).
83 DTYPE_RODIRECT CD-ROM device.
86 DTYPE_SCANNER Scanner device.
89 DTYPE_OPTICAL Optical memory device (for example, some optical
92 disks).
93 DTYPE_CHANGER Medium Changer device (for example, jukeboxes).
96 DTYPE_COMM Communications device.
99 DTYPE_ARRAY_CTRL Array controller device (for example, RAID).
102 DTYPE_ESI Enclosure services device.
105 DTYPE_RBC Simplified direct-access device.
108 DTYPE_OCRW Optical card reader/writer device.
111 DTYPE_BRIDGE Bridge.
114 DTYPE_OSD Object-based storage device.
117 DTYPE_UNKNOWN Unknown or no device type.
120 DTYPE_MASK Mask to isolate Peripheral Device Type field.
123 The following values are appropriate for the Peripheral Qualifier
127 field:
128 DPQ_POSSIBLE The specified peripheral device type is currently con‐
130 nected to this logical unit. If the target cannot
131 determine whether or not a physical device is cur‐
132 rently connected, it uses this peripheral qualifier
133 when returning the INQUIRY data. This peripheral qual‐
134 ifier does not imply that the device is ready for
135 access by the initiator.
136 DPQ_SUPPORTED The target is capable of supporting the specified
139 peripheral device type on this logical unit. However,
140 the physical device is not currently connected to this
141 logical unit.
142 DPQ_NEVER The target is not capable of supporting a physical
145 device on this logical unit. For this peripheral qual‐
146 ifier, the peripheral device type shall be set to
147 DTYPE_UNKNOWN to provide compatibility with previous
148 versions of SCSI. For all other peripheral device type
149 values, this peripheral qualifier is reserved.
150 DPQ_VUNIQ This is a vendor-unique qualifier.
153 DPQ_MASK Mask to isolate Peripheral Qualifier field.
156 DTYPE_NOTPRESENT is the peripheral qualifier DPQ_NEVER and the periph‐
160 eral device type DTYPE_UNKNOWN combined.
161 inq_rmb, if set, indicates that the medium is removable.
164 inq_qual is a device type qualifier.
167 inq_iso indicates ISO version.
170 inq_ecma indicates ECMA version.
173 inq_ansi indicates ANSI version.
176 inq_aenc, if set, indicates that the device supports asynchronous event
179 notification capability as defined in SCSI-2 specification.
180 inq_trmiop, if set, indicates that the device supports the TERMINATE
183 I/O PROCESSmessage.
184 inq_normaca, if set, indicates that the device supports setting the
187 NACA bit to 1 in CDB.
188 inq_hisip, if set, indicates the SCSI target device uses the hierarchi‐
191 cal addressing model to assign LUNs to logical units.
192 inq_rdf, if set, indicates the INQUIRY data response data format:
195 "RDF_LEVEL0" means that this structure complies with the SCSI-1 spec,
196 "RDF_CCS" means that this structure complies with the CCS pseudo-spec,
197 and "RDF_SCSI2" means that the structure complies with the SCSI-2/3
198 spec.
199 inq_len, if set, is the additional length field that specifies the
202 length in bytes of the parameters.
203 inq_sccs, if set, indicates the target device contains an embedded
206 storage array controller component.
207 inq_acc, if set, indicates that the logical unit contains an access
210 controls coordinator (this structure member will be deleted before sub‐
211 mission. It is being classified as unstable at this time).
212 inq_tpgse, if set, indicates that implicit asymmetric logical unit
215 access is supported.
216 inq_tpgsi, if set, indicates that explicit asymmetric logical unit
219 access is supported.
220 inq_3pc, if set, indicates that the SCSI target device supports third-
223 party copy commands (this structure member will be deleted before sub‐
224 mission. It is being classified as unstable at this time).
225 inq_protect, if set, indicates that the logical unit supports protec‐
228 tion information (this structure member will be deleted before submis‐
229 sion. It is being classified as unstable at this time).
230 inq_bque, if set, indicates that the logical unit supports basic task
233 management.
234 inq_encserv, if set, indicates that the device contains an embedded
237 enclosure services component (ses(7D)).
238 inq_dualp, if set, indicates that the SCSI target device supports two
241 or more ports.
242 inq_mchngr, if set, indicates that the SCSI target device supports com‐
245 mands to control an attached media changer.
246 inq_addr16, if set, indicates that the device supports 16-bit wide SCSI
249 addresses.
250 inq_wbus16, if set, indicates that the device supports 16-bit wide data
253 transfers.
254 inq_sync, if set, indicates that the device supports synchronous data
257 transfers.
258 inq_linked, if set, indicates that the device supports linked commands
261 for this logical unit.
262 inq_cmdque, if set, indicates that the device supports tagged command
265 queueing.
266 inq_sftre, if reset, indicates that the device responds to the RESET
269 condition with the hard RESET alternative. If this bit is set, this
270 indicates that the device responds with the soft RESET alternative.
271 inq_vid contains eight bytes of ASCII data identifying the vendor of
274 the product.
275 inq_pid contains sixteen bytes of ASCII data as defined by the vendor.
278 inq_revision contains four bytes of ASCII data as defined by the ven‐
281 dor.
282 inq_clk clocking of the SPI3 target port.
285 inq_gas the SPI3 target port supports quick arbitration and selection.
288 inq_ius the SPI3 target device supports information unit transfers.
