Kernel Properties for Drivers             inquiry-device-type(9P)



NAME
     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 sys-
     tem, 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 pro-
     perty should compare the property 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 scsiinquiry(9S) "inqvid" field.


     inquiry-product-id is a string property.  When  present,  it
     contains  the product identification. This information typi-
     cally comes from the scsiinquiry(9S) "inqpid" field.


     inquiry-revision-id is a string property. When  present,  it
     contains the product revision. This revision typically comes
     from the scsiinquiry(9S) "inqrev" 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  trantgtinit(9E)  time  by  an  HBA
     driver  take  precedence over values established by the sys-
     tem, and HBA driver values may not be the same length as the
     typical scsiinquiry(9S) field.
