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] [--zero] SMP_DEVICE[,N]

DESCRIPTION

       Sends  a SAS Serial Management Protocol (SMP) REPORT ROUTE INFORMATION function request to an 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 supersedes 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 .
