Overview
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.
