NAMEsmp_rep_route_info - invoke REPORT ROUTE INFORMATION SMP function
SYNOPSISsmp_rep_route_info [--help] [--hex] [--index=IN] [--interface=PARAMS] [--multiple] [--num=NUM] [--phy=ID] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]
Sends a SAS Management Protocol (SMP) REPORT ROUTE INFORMATION function to a 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. With one interface there is one SMP_DEVICE per machine so the SMP_DEVICE,N syntax is needed to differentiate between HBAs if there are multiple present.
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.
When the --multiple option is given, the REPORT ROUTE INFORMATION function is called multiple times. The index value increments on each iteration, starting from --index=IN (default 0). If --num=NUM is given and NUM is greater than zero then that is the maximum number of iterations performed. If --num=NUM is not given (or NUM is zero) then iterations continue until there are 4 adjacent disabled route entries (or some error is detected).
OPTIONSMandatory arguments to long options are mandatory for short options as well.
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response in hexadecimal.
- -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.
- -m, --multiple
- call the REPORT ROUTE INFORMATION function multiple times, starting at --index=IN, incrementing the index value on each iteration for a maximum of --num=NUM iterations. For each enabled route table entry, one line is output. If --num=NUM is not given (or NUM is zero) then iterations continue until 4 adjacent disabled entries are found (or some error occurs).
- -n, --num=NUM
- used with --multiple option to specify the maximum number of iterations.
- -p, --phy=ID
- phy identifier. ID is a value between 0 and 127. Default is 0.
- -r, --raw
- send the response 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.
CONFORMING TOThe SMP REPORT ROUTE INFORMATION function was introduced in SAS-1 . The "Expander change count" field was added in SAS-2 .
