sg_rtpg: send SCSI REPORT TARGET PORT GROUPS command

NAME

sg_rtpg - send SCSI REPORT TARGET PORT GROUPS command

SYNOPSIS

sg_rtpg [--decode] [--help] [--hex] [--raw] [--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 found at www.t10.org in section 5.8 (in rev 21c dated 2005/1/15). The Report Target Port Groups command is also described in that document.

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.

-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.

-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.
