smp_rep_general: invoke REPORT GENERAL SMP function
NAMEsmp_rep_general - invoke REPORT GENERAL SMP function
SYNOPSISsmp_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.
OPTIONSMandatory 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.

CONFORMING TOThe 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 .
