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 .
