  * PROBLEM DESCRIPTION:                                         *
  * Probes of the Spectrum Scale of an ESS 3000 may fail         *
  * when adding the Spectrum Scale portion of an ESS 3000.       *
  *                                                              *
  * The probe may fail on some models due to new NSD to node     *
  * class reporting feature in Spectrum Scale / ESS 3000.        *
  *                                                              *
  * This fix implements a workaround to ensure the probe         *
  * completes successfully if that feature is encountered.       *
  *                                                              *
  * Please note:                                                 *
  * There is a limitation that no NSD to Node information is     *
  * collected or available due to the new NSD to node class      *
  * reporting.                                                   *

  * NSDs the "NSD Servers" column is empty, and for Nodes the    *
