13
15 Sends a SAS Serial Management Protocol (SMP) CONFIGURE ROUTE INFORMA‐
16 TION function request to an SMP target. The SMP target is identified by
17 the SMP_DEVICE and the --sa=SAS_ADDR. Depending on the interface, the
18 SAS_ADDR may be deduced from the SMP_DEVICE. The mpt interface uses
19 SMP_DEVICE to identify a HBA (an SMP initiator) and needs the addi‐
20 tional ,N to differentiate between HBAs if there are multiple present.
21
22 There are two expander route table types: phy-based and expander-based.
23 The expander-based route table was introduced in SAS-2 and supersedes
24 the phy-based route tables. The CONFIGURE ROUTE INFORMATION function is
25 associated with a phy-based route table. The REPORT ROUTE INFORMATION
26 function is provided to report phy-based route table entries.
27
28 Each phy in a SAS expander that has an associated routing attribute of
29 "table" has a router table. The number of rows (or entries) in each
30 router table is given by the "expander route indexes" field in the
31 response of the REPORT GENERAL function.
32
34 Mandatory arguments to long options are mandatory for short options as
35 well.
36
37 -d, --disable
38 set the "disable expander route entry" flag in a row of the
39 router table associated with --phy=ID of the given SMP target
40 (e.g. an expander). Within the router table the row that is
41 disabled is identified by the expander route index given by
42 --index=IN.
43
44 -E, --expected=EX
45 set the 'expected expander change count' field in the SMP
46 request. The value EX is from 0 to 65535 inclusive with 0 being
47 the default value. When EX is greater than zero then if the
48 value doesn't match the expander change count of the SMP target
49 (i.e. the expander) when the request arrives then the target
50 ignores the request and sets a function result of "invalid
51 expander change count" in the response.
52
53 -h, --help
54 output the usage message then exit.
55
56 -H, --hex
57 output the response (less the CRC field) in hexadecimal.
58
59 -i, --index=IN
60 expander route index. IN is a value between 0 and 65535. Default
61 is 0. More precisely the maximum index value is
62 (expander_route_indexes - 1).
63
64 -I, --interface=PARAMS
65 interface specific parameters. In this case "interface" refers
66 to the path through the operating system to the SMP initiator.
67 See the smp_utils man page for more information.
68
69 -p, --phy=ID
70 phy identifier. ID is a value between 0 and 254. Default is 0.
71
72 -r, --raw
73 send the response (less the CRC field) to stdout in binary. All
74 error messages are sent to stderr.
75
76 -R, --routed=R_SAS_ADDR
77 specifies the SAS address to be placed in a row (given by
78 --index=IN) of the router table associated with --phy=ID.
79 Default value is 0. The R_SAS_ADDR is in decimal but most SAS
80 addresses are given in hexadecimal. To give a number in hexadec‐
81 imal either prefix it with '0x' or put a trailing 'h' on it.
82
83 -s, --sa=SAS_ADDR
84 specifies the SAS address of the SMP target device. Typically
85 this is an expander. This option may not be needed if the
86 SMP_DEVICE has the target's SAS address within it. The SAS_ADDR
87 is in decimal but most SAS addresses are shown in hexadecimal.
88 To give a number in hexadecimal either prefix it with '0x' or
89 put a trailing 'h' on it.
90
91 -v, --verbose
92 increase the verbosity of the output. Can be used multiple times
93
94 -V, --version
95 print the version string and then exit.
96
98 The SMP CONFIGURE ROUTE INFORMATION function was introduced in SAS-1 .
99 The "Expander change count" field was added in SAS-2 .
