sminfo(8)

Name
sminfo - query InfiniBand SMInfo attribute

SYNOPSIS

sminfo [options] sm_lid | sm_dr_path [modifier]

DESCRIPTION

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

-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: /etc/infiniband-diags/ibdiag.conf

EXAMPLES

    sminfo                  # local port\'s sminfo
    sminfo 32               # show sminfo of lid 32
    sminfo  -G 0x8f1040023  # same but using guid address
