sg_rtpg - Man Page

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

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 .

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.

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.]

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