SMINFO(8)                  Open IB Diagnostics                  SMINFO(8)

NAME         top

       sminfo - query InfiniBand SMInfo attribute

SYNOPSIS         top

       sminfo [options] sm_lid | sm_dr_path [modifier]

DESCRIPTION         top

       Optionally set and display the output of a sminfo query in human
       readable format. The target SM is the one listed in the local port
       info, or the SM specified by the optional SM lid or by the SM
       direct routed path.

       Note: using sminfo for any purposes other then simple query may be
       very dangerous, and may result in a malfunction of the target SM.

OPTIONS         top

       -s, --state <state> set SM state
              0 not active

              1 discovering

              2 standby

              3 master

       -p, --priority <priority> set priority (0-15)

       -a, --activity <val> set activity count

   Addressing Flags
       -D, --Direct     The address specified is a directed route

          Examples:
             [options] -D [options] "0"          # self port
             [options] -D [options] "0,1,2,1,4"  # out via port 1, then 2, ...

             (Note the second number in the path specified must match the port being
             used.  This can be specified using the port selection flag '-P' or the
             port found through the automatic selection process.)

       -G, --Guid     The address specified is a Port GUID

       -L, --Lid   The address specified is a LID

   Port Selection flags
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

   Local port Selection
       Multiple port/Multiple CA support: when no IB device or port is
       specified (see the "local umad parameters" below), the libibumad
       library selects the port to use by the following criteria:

          1. the first port that is ACTIVE.

          2. if not found, the first port that is UP (physical link up).

          If a port and/or CA name is specified, the libibumad library
          attempts to fulfill the user request, and will fail if it is
          not possible.

          For example:

              ibaddr                 # use the first port (criteria #1 above)
              ibaddr -C mthca1       # pick the best port from "mthca1" only.
              ibaddr -P 2            # use the second (active/up) port from the first available IB device.
              ibaddr -C mthca0 -P 2  # use the specified port only.

   Debugging flags
       -d     raise the IB debugging level.  May be used several times
              (-ddd or -d -d -d).

       -e     show send and receive errors (timeouts and others)

       -h, --help      show the usage message

       -v, --verbose
              increase the application verbosity level.  May be used
              several times (-vv or -v -v -v)

       -V, --version     show the version info.

   Configuration flags
       -t, --timeout <timeout_ms> override the default timeout for the
       solicited mads.

       -y, --m_key <key>
              use the specified M_key for requests. If non-numeric value
              (like 'x') is specified then a value will be prompted for.

       --config, -z  <config_file> Specify alternate config file.
          Default:
          /ssd11/FOSS/rdma-core/build/etc/infiniband-diags/ibdiag.conf
