Sends a SAS Serial Management Protocol (SMP) CONFIGURE GENERAL function request
to an SMP target. The SMP target is identified by the SMP_DEVICE
. Depending on the interface, the SAS_ADDR
be deduced from the SMP_DEVICE
. The mpt interface uses
to identify a HBA (an SMP initiator) and needs the
to differentiate between HBAs if there are multiple
Mandatory arguments to long options are mandatory for short options as well.
- -c, --connect=CO
- sets the "update STP maximum connect time limit"
flag and the corresponding "STP maximum connect time limit"
field to CO. Unit of CO is 100 microseconds. A CO of
zero is taken to mean no maximum connection time limit.
- -E, --expected=EX
- set the 'expected expander change count' field in the SMP
request. The value EX is from 0 to 65535 inclusive with 0 being the
default value. When EX is greater than zero then if the value
doesn't match the expander change count of the SMP target (i.e. the
expander) when the request arrives then the target ignores the request and
sets a function result of "invalid expander change count" in the
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in
- -i, --inactivity=IN
- sets the "update STP bus inactivity time limit"
flag and the corresponding "STP bus inactivity time limit" field
to IN. Unit of IN is 100 microseconds. A IN of zero
is taken to mean no bus inactivity time limit.
- -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.
- -n, --nexus=NE
- sets the "update STP SMP I_T nexus loss time"
flag and the corresponding "STP SMP I_T nexus loss time" field
to NE. Unit of NE is one millisecond. A NE of zero is
taken to mean a vendor specific amount of time; a NE of 65535 means
the port shall never recognize an I_T nexus loss.
- -o, --open=OP
- sets the "update STP reject to open limit" flag
and the corresponding "STP reject to open limit" field to
OP. Unit of OP is 10 microseconds.
- -p, --power=PD
- sets the "update power done timeout" flag and the
corresponding "power doen timeout" field to PD. Unit of
PD is 1 second. A PD value of 0 is interpreted as don't
change the current value. The maximum value of PD is 255 and means
the time limit is vendor specific.
- -r, --raw
- send the response (less the CRC field) to stdout in binary.
All error messages are sent to stderr.
- -R, --reduced=RE
- sets the "update Initial time to reduced
functionality" flag and the corresponding "Initial time to
reduced functionality" field to RE. Unit of RE is 100
milliseconds. The maximum permitted RE value is 255 which
corresponds to 25.5 seconds.
- -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
- -V, --version
- print the version string and then exit.
The SMP CONFIGURE GENERAL function was introduced in SAS-2 .
