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.
decodes the status code and asymmetric access state from each target port group descriptor returned. The default action is not to decode these values.
use extended header format for parameter data. This sets the PARAMETER DATA FORMAT field in the cdb to 1.
output the usage message then exit.
output response in hex (rather than partially or fully decode it).
output response in binary to stdout.
open the DEVICE read-only (e.g. in Unix with the O_RDONLY flag). The default is to open it read-write.
increase the level of verbosity, (i.e. debug output).
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.
