NAME

       RDMA-NDD - RDMA device Node Description update daemon

SYNOPSIS

       rdma-ndd <options>

DESCRIPTION

       rdma-ndd is a system daemon which watches for rdma device changes and/or hostname changes and updates the
       Node Description of the rdma devices based on those changes.

DETAILS

       Full  operation of this daemon requires kernels which support polling of the procfs hostname file as well
       as libudev.

       If your system does not support either of these features, the daemon will set the  Node  Descriptions  at
       start up and then sleep forever.

   Node Description format
       The  daemon  uses the nd_format configuration option within the ibdiags.conf file.  %h and %d can be used
       as wildcards in that string to specify the dynamic use of <hostname> and <device> respectively.

       NOTE: At startup and on new device detection the Node Description is always written to ensure the SM  and
       this  daemon  are  in sync.  Subsequent events will only write the Node Description on a device if it has
       changed.

OPTIONS

       --retry_timer, -t Length of time to sleep when system errors occur when attempting to poll  and  or  read
       the hostname from the system.

       --retry_count,  -r  Number  of  times  to  attempt  to  retry setting of the node description on failure.
       Default 0

       --foreground, -f Run in the foreground instead of as a daemon

       --pidfile <pidfile> specify a pid file (daemon mode only)

   Configuration flags
       --config, -z  <config_file> Specify alternate config file.
          Default: /etc/infiniband-diags/ibdiag.conf

   Debugging flags
       -h, --help      show the usage message

       -V, --version     show the version info.
