NAME
       sg_rtpg - send SCSI REPORT TARGET PORT GROUPS command

SYNOPSIS
       sg_rtpg	[--decode]  [--help]  [--hex] [--raw] [--readonly] [--verbose]
       [--version] DEVICE

DESCRIPTION
       Send a SCSI REPORT TARGET PORT GROUPS command to DEVICE and outputs the
       response.

       Target  port  group  access  is	described  in SPC-3 and SPC-4 found at
       www.t10.org . The most recent draft of SPC-4 is revision	 37  in	 which
       target port groups are described in section 5.15 .

OPTIONS
       Arguments to long options are mandatory for short options as well.

       -d, --decode
	      decodes  the  status  code and asymmetric access state from each
	      target port group descriptor returned. The default action is not
	      to decode these values.

       -e, --extended
	      use  extended  header  format  for parameter data. This sets the
	      PARAMETER DATA FORMAT field in the cdb to 1.

       -h, --help
	      output the usage message then exit.

       -H, --hex
	      output response in hex (rather than partially  or	 fully	decode
	      it).

       -r, --raw
	      output response in binary to stdout.

       -R, --readonly
	      open the DEVICE read-only (e.g. in Unix with the O_RDONLY flag).
	      The default is to open it read-write.

       -v, --verbose
	      increase the level of verbosity, (i.e. debug output).

       -V, --version
	      print the version string and then exit.

NOTES
       The Report Target Port Groups command should be supported whenever  the
       TPGS  bits  in a standard INQUIRY response are greater than zero. [View
       with sg_inq utility.]

EXIT STATUS
       The exit status of sg_rtpg is 0 when it is  successful.	Otherwise  see
       the sg3_utils(8) man page.
