## 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 re‐
       cent 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 de‐
              scriptor 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  stan‐
       dard 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)](https://www.chedong.com/phpMan.php/man/sg3utils/8/markdown) man
       page.
