       scsi_id - retrieve and generate a unique SCSI identifier

       scsi_id [options]

       scsi_id  queries  a SCSI device via the SCSI INQUIRY vital product data
       (VPD) page 0x80 or 0x83 and uses the resulting data to generate a value
       that  is unique across all SCSI devices that properly support page 0x80
       or page 0x83.

       If a result is generated it is sent to standard output, and the program
       exits  with a zero value. If no identifier is output, the program exits
       with a non-zero value.

       scsi_id is primarily for use by  other  utilities  such  as  udev  that
       require a unique SCSI identifier.

       By  default  all  devices  are  assume  black listed, the --whitelisted
       option must be specified on the command line or in the config file  for
       any useful behaviour.

       SCSI  commands  are  sent  directly  to  the device via the SG_IO ioctl

       In order to generate unique values for either page 0x80 or  page  0x83,
       the serial numbers or world wide names are prefixed as follows.

       Identifiers  based  on page 0x80 are prefixed by the character 'S', the
       SCSI vendor, the SCSI product (model) and then the  the  serial  number
       returned by page 0x80. For example:

       # /lib/udev/scsi_id --page=0x80 --whitelisted --device=/dev/sda
       SIBM     3542           1T05078453

       Identifiers based on page 0x83 are prefixed by the identifier type fol-
       lowed by the page 0x83 identifier. For example, a  device  with  a  NAA
       (Name  Address  Authority)  type  of 3 (also in this case the page 0x83
       identifier starts with the NAA value of 6):

       # /lib/udev/scsi_id --page=0x83 --whitelisted --device=/dev/sda

              The default behaviour - treat the device as black listed, and do
              nothing  unless  a  white  listed device is found in the scsi_id

              Send SG_IO commands to device, such as /dev/sdc.

              Read configuration and black/white list entries from config-file
              rather than the default /etc/scsi_id.config file.

              Treat  the device as white listed. The --whitelisted option must
              be specified on the command line or in the scsi_id configuration
              file for scsi_id to generate any output.

              Use SCSI INQUIRY VPD page code 0x80, 0x83, or pre-spc3-83.

              The  default  behaviour is to query the available VPD pages, and
              use page 0x83 if found, else page 0x80 if found, else nothing.

              Page pre-spc3-83 should only be utilized for those scsi  devices
              which  are not compliant with the SPC-2 or SPC-3 format for page
              83.  While this option is used for older model 4, 5, and  6  EMC
              Symmetrix devices, its use with SPC-2 or SPC-3 compliant devices
              will fallback to the page 83 format supported by these  devices.

              Reformat the output : replace all whitespaces by underscores.

              Export  all  data  in KEY=<value> format used to import in other

              Generate verbose debugging output.

              Display version number and exit.

       If the DEVPATH environment variable is set, scsi_id assumes it has been
       invoked  via  udev  (or  some other hotplug program), and all errors or
       warnings are sent using syslog.
