# sg\_rtpg(8)

send SCSI REPORT TARGET PORT GROUPS command

## 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)](/sg3_utils/8.md) man page.
