NAME
sg_rtpg - send SCSI REPORT TARGET PORT GROUPS commandSYNOPSIS
sg_rtpg [--decode] [--help] [--hex] [--raw] [--readonly] [--verbose] [--version] DEVICEDESCRIPTION
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.AUTHORS
