An Example - The SCSI Inquiry Command

• The SCSI Inquiry Command allows us to get information about the device.
• When we send the SCSI command, we need to state which 'page' we want to access.
• All SCSI targets must respond to inquiries to page 0x80. often they have a vendor-specific response to page 0x83 too.
• An example, using the sg_inq command from the sg3-utils package:

  [choo@simey ~]# sg_inq /dev/sg0
  standard INQUIRY:
    PQual=0  Device_type=5  RMB=1  version=0x02  [SCSI-2]
    [AERC=0]  [TrmTsk=0]  NormACA=0  HiSUP=0  Resp_data_format=2
    SCCS=0  ACC=0  TGPS=0  3PC=0  Protect=0  BQue=0
    EncServ=0  MultiP=0  [MChngr=0]  [ACKREQQ=0]  Addr16=0
    [RelAdr=0]  WBus16=0  Sync=1  Linked=0  [TranDis=0]  CmdQue=0
