smp_rep_general - invoke REPORT GENERAL SMP function
smp_rep_general [--brief] [--changecount]
[--help] [--hex] [--interface=PARAMS] [--raw]
[--sa=SAS_ADDR] [--verbose] [--version] [--zero]
SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) REPORT GENERAL
function request to an SMP target. The SMP target is identified by the
SMP_DEVICE and the SAS_ADDR. Depending on the interface, the
SAS_ADDR may be deduced from the SMP_DEVICE. The mpt interface
uses SMP_DEVICE to identify a HBA (an SMP initiator) and needs the
additional ,N to differentiate between HBAs if there are multiple
present.
Mandatory arguments to long options are mandatory for short
options as well.
- -b, --brief
- reports (prints to stdout) only a few important fields from the
response.
- -c,
--changecount
- reports (prints to stdout) the value of the expander change count field
from the response. The value is printed in decimal and is in the range 0
to 65535. Only expanders compliant with SAS-1.1 (and earlier) should yield
0. [Expanders compliant with SAS-2 (and later) should set the "long
response" bit in the REPORT GENERAL response to 1.]
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in hexadecimal.
- -I,
--interface=PARAMS
- interface specific parameters. In this case "interface" refers
to the path through the operating system to the SMP initiator. See the
smp_utils man page for more information.
- -r, --raw
- send the response (less the CRC field) to stdout in binary. All error
messages are sent to stderr.
- -s,
--sa=SAS_ADDR
- specifies the SAS address of the SMP target device. Typically this is an
expander. This option may not be needed if the SMP_DEVICE has the
target's SAS address within it. The SAS_ADDR is in decimal but most
SAS addresses are shown in hexadecimal. To give a number in hexadecimal
either prefix it with '0x' or put a trailing 'h' on it.
- -v, --verbose
- increase the verbosity of the output. Can be used multiple times
- -V, --version
- print the version string and then exit.
- -z, --zero
- zero the Allocated Response Length field in the request. This is required
for strict SAS-1.1 compliance. However this option should not be given in
SAS-2 and later; if it is given an abridged response may result.
See "Examples" section in

The SMP REPORT GENERAL function was introduced in SAS-1, with
small additions in SAS-1.1 . There have been a large number of additions in
SAS-2 .
