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.
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 .
