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.
