NAME
smp_rep_route_info - invoke REPORT ROUTE INFORMATION SMP function
SYNOPSIS
smp_rep_route_info [--help] [--hex] [--index=IN] [--interface=PARAMS] [--multiple] [--num=NUM] [--phy=ID] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]
DESCRIPTION
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).
OPTIONS
Mandatory 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 targets 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 TO
The SMP REPORT ROUTE INFORMATION function was introduced in SAS-1 . The "Expander change count" field was added in SAS-2 .
