Sends a SAS Serial Management Protocol (SMP) CONFIGURE ROUTE INFORMATION
function request to an SMP target. The SMP target is identified by the
and the --sa=SAS_ADDR
. Depending on the interface,
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
There are two expander route table types: phy-based and expander-based. The
expander-based route table was introduced in SAS-2 and supersedes the
phy-based route tables. The CONFIGURE ROUTE INFORMATION function is associated
with a phy-based route table. The REPORT ROUTE INFORMATION function is
provided to report phy-based route table entries.
Each phy in a SAS expander that has an associated routing attribute of
"table" has a router table. The number of rows (or entries) in each
router table is given by the "expander route indexes" field in the
response of the REPORT GENERAL function.
Mandatory arguments to long options are mandatory for short options as well.
- -d, --disable
- set the "disable expander route entry" flag in a
row of the router table associated with --phy=ID of the given SMP
target (e.g. an expander). Within the router table the row that is
disabled is identified by the expander route index given by
- -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, --index=IN
- expander route index. IN is a value between 0 and
65535. Default is 0. More precisely the maximum index value is
(expander_route_indexes - 1).
- -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.
- -p, --phy=ID
- phy identifier. ID is a value between 0 and 254.
Default is 0.
- -r, --raw
- send the response (less the CRC field) to stdout in binary.
All error messages are sent to stderr.
- -R, --routed=R_SAS_ADDR
- specifies the SAS address to be placed in a row (given by
--index=IN) of the router table associated with --phy=ID.
Default value is 0. The R_SAS_ADDR is in decimal but most SAS
addresses are given in hexadecimal. To give a number in hexadecimal either
prefix it with '0x' or put a trailing 'h' on it.
- -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 ROUTE INFORMATION function was introduced in SAS-1 . The
"Expander change count" field was added in SAS-2 .
