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] [--ver-
       bose] [--version] [--zero] SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Management Protocol (SMP) REPORT ROUTE INFORMATION function request 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. 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  super-
       sedes  the  phy-based  route  tables. The REPORT ROUTE INFORMATION function is associated with a phy-based route table. The CONFIGURE ROUTE
       INFORMATION function is provided to manually set up a phy-based route table.

       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 (less the CRC field) 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 254. Default is 0.

       -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.

       -z, --zero
	      zero the Allocated Response Length field in the request. This option also zeros the Request Length field in  the	request.  This	is
	      required	for  strict  SAS-1.1  compliance.  However  this option should not be given in SAS-2 and later; if it is given an abridged
	      response may result.

CONFORMING TO

       The SMP REPORT ROUTE INFORMATION function was introduced in SAS-1 .  The "Expander change count" field was added in SAS-2 .
