NAME
sg_rtpg - send SCSI REPORT TARGET PORT GROUPS command
SYNOPSIS
sg_rtpg
[--decode] [--help] [--hex] [--raw]
[--readonly] [--verbose] [--version] DEVICE
DESCRIPTION
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.
