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

CONFORMING TO¶

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 .
