Problem summary

• ****************************************************************
  * USERS AFFECTED: TPC 4.1.x and 4.2.x users of Data Path       *
  *                 Explorer where the Disks reside on a         *
  *                 Windows server                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: TPC is unable to generate all data      *
  *                      paths for disks that reside on a        *
  *                      Windows server when the data paths      *
  *                      have been physically disconnected and   *
  *                      reconnected from the fabric.            *
  *                                                              *
  *                      A TPC Data agent successfully probed    *
  *                      on a supported Windows system does      *
  *                      not yield all the path information      *
  *                      needed for the TPC Data Path Explorer   *
  *                      (DPE) in the TPC Topology viewer after  *
  *                      a fabric connection has been            *
  *                      physically disconnected and             *
  *                      reconnected.  When attempting to        *
  *                      generate the data paths, only some of   *
  *                      the data paths are found.  This         *
  *                      occurs even when successfully probing   *
  *                      the fabrics and subsystems that         *
  *                      contain the connection information      *
  *                      needed to relate the storage subsystem  *
  *                      volumes to the Windows disks.  This     *
  *                      also occurs after a reboot of the       *
  *                      Windows system following the            *
  *                      connection of the host ports to the     *
  *                      fabric.                                 *
