sg_rtpg - send SCSI REPORT TARGET PORT GROUPS command
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.
