NAME

       smp_rep_exp_route_tbl - invoke REPORT EXPANDER ROUTE TABLE LIST SMP function

SYNOPSIS

       smp_rep_exp_route_tbl   [--brief]   [--help]   [--hex]  [--index=IN]  [--interface=PARAMS]
       [--num=NUM] [--phy=ID] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Serial Management Protocol (SMP) REPORT EXPANDER  ROUTE  TABLE  LIST  function
       request to an SMP target and decodes or outputs the response. 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 EXPANDER ROUTE TABLE LIST function is associated with an expander-based
       route table. There is no corresponding CONFIGURE function because a  expander-based  route
       table is self-configured.

OPTIONS

       Mandatory arguments to long options are mandatory for short options as well.

       -b, --brief
              reduce the decoded response output.

       -h, --help
              output the usage message then exit.

       -H, --hex
              output the response (less the CRC field) in hexadecimal.

       -i, --index=IN
              IN is the starting routed SAS address index. The default value is 0.

       -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.

       -n, --num=NUM
              maximum number of descriptors to fetch (default is 62). Note that maximum SMP frame
              size is 1028 bytes (including a trailing 4 byte  CRC)  so  62  descriptors  is  the
              maximum number that can fit in one response.

       -p, --phy=ID
              starting  phy  identifier  within bitmap. ID should be one of 0 (the default), or a
              multiple of 48. Note there is only one expnder route table per  expander,  not  one
              per phy.

       -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.

CONFORMING TO
