SMP_REP_GENERAL(8)

NAME
smp_rep_general - invoke REPORT GENERAL SMP function

SYNOPSIS
smp_rep_general [--brief] [--changecount] [--help] [--hex] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] [--zero] SMP_DEVICE[,N]

DESCRIPTION

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.

OPTIONS
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.

EXAMPLES
See "Examples" section in http://sg.danny.cz/sg/smp_utils.html
