NAME¶
smp_rep_exp_route_tbl - invoke REPORT EXPANDER ROUTE TABLE LIST SMP function
SYNOPSIS¶
smp_rep_exp_route_tbl [
--brief] [
--help] [
--hex] [
--index=IN] [
--interface=PARAMS] [
--num=NUM] [
--phy=ID] [
--raw] [
--sa=SAS_ADDR] [
--verbose]
[
--version]
SMP_DEVICE[,N]
DESCRIPTION¶
Sends a SAS Management Protocol (SMP) REPORT EXPANDER ROUTE TABLE LIST function
request to a SMP target and decodes or outputs the response. 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.
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 REPORT EXPANDER ROUTE TABLE LIST function is
associated with an expander-based route table. There is no corresponding
CONFIGURE function because a expander-based route table is self-configured.
OPTIONS¶
Mandatory arguments to long options are mandatory for short options as well.
- -b, --brief
- reduce the decoded response output.
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in
hexadecimal.
- -i, --index=IN
- IN is the starting routed SAS address index. The
default value is 0.
- -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, --num=NUM
- maximum number of descriptors to fetch (default is 62).
Note that maximum SMP frame size is 1028 bytes (including a trailing 4
byte CRC) so 62 descriptors is the maximum number that can fit in one
response.
- -p, --phy=ID
- starting phy identifier within bitmap. ID should be
one of 0 (the default), or a multiple of 48. Note there is only one
expnder route table per expander, not one per phy.
- -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.
The SMP REPORT EXPANDER ROUTE TABLE LIST function was introduced in SAS-2 .
