SYMPTOMS

Consider the following scenario:
  • You connect a Windows Server 2008-based computer to a storage device that is controlled by Microsoft Multipath I/O (MPIO).
  • You use a third-party device specific module (DSM) for MPIO.
  • You disconnect all data cables and then reconnect them.
In this scenario, access to the storage device fails. Therefore, applications that try to access the storage device crash or receive an exception. This problem persists until you restart the Windows Server 2008-based computer.
