inquiry-device-type, inquiry-vendor-id, inquiry-product-id, inquiry-
revision-id, inquiry-serial-no - inquiry properties for SCSI devices
DESCRIPTION
These are optional properties, typically created by the system, for
SCSI target devices. References to these properties should use their
sys/scsi/impl/inquiry.h defined names.
inquiry-device-type is an integer property. When present, the least
significant byte of the value indicates the device type as defined by
the SCSI standard. Consumers of this property should compare the prop‐
erty values with DTYPE_* values defined in sys/scsi/generic/inquiry.h.
inquiry-vendor-id is a string property. When present, it contains the
vendor information. This information typically comes from the
scsi_inquiry(9S) "inq_vid" field.
inquiry-product-id is a string property. When present, it contains the
product identification. This information typically comes from the
scsi_inquiry(9S) "inq_pid" field.
inquiry-revision-id is a string property. When present, it contains the
product revision. This revision typically comes from the
scsi_inquiry(9S) "inq_rev" field.
inquiry-serial-no is a string property. When present, it contains the
serial number. The serial number is typically obtained from the EVPD
"Unit Serial Number" SCSI INQUIRY data (page 0x80).

NOTES
Values established at tran_tgt_init(9E) time by an HBA driver take
precedence over values established by the system, and HBA driver values
may not be the same length as the typical scsi_inquiry(9S) field.
