       sminfo - query InfiniBand SMInfo attribute


       sminfo   [-d(ebug)]   [-e(rr_show)]   -s  state  -p  prio  -a  activity
       [-D(irect)]  [-G(uid)]    [-C   ca_name]   [-P   ca_port]   [-t(imeout)
       timeout_ms] [-V(ersion)] [-h(elp)] sm_lid | sm_dr_path [modifier]


       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.


       -s     set SM state
               0 - not active
               1 - discovering
               2 - standby
               3 - master

       -p     set priority (0-15)

       -a     set activity count


       Most OpenIB diagnostics take the following common flags. The exact list
       of supported flags per utility can be found in the  usage  message  and
       can be shown using the util_name -h syntax.

       # 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      show the usage message

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

       -V      show the version info.

       # Addressing flags

       -D      use directed path address arguments. The path
               is a comma separated list of out ports.
               "0"             # self port
               "0,1,2,1,4"     # out via port 1, then 2, ...

       -G       use GUID address argument. In most cases, it is the Port GUID.

       -s <smlid>      use ’smlid’ as the target lid for SM/SA queries.

       # Other common flags:

       -C <ca_name>    use the specified ca_name.

       -P <ca_port>    use the specified ca_port.

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

       Multiple CA/Multiple Port Support

       When no IB device or port is specified, the port to use is selected  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 user request is attempted to
       be fulfilled, and will fail if it is not possible.


       sminfo                  # local port´s sminfo

       sminfo 32               # show sminfo of lid 32

       sminfo  -G 0x8f1040023  # same but using guid address
