Error description

• A 7.1.3.0 Tivoli Storage Manager B/A Client which is installed
  on a Windows cluster can crash during a HYPER-V based BACKUP VM
  command if one or more of the Virtual Machines (VMs) vhdx files
  are located on a cluster disk.
  
  Note that the crash will not happen on a system that is not
  part of a cluster or if the vhdx files are stored on a Cluster
  Shared Volume.
  
  Tivoli Storage Manager Versions Affected:
  7.1.3.0
  
  Diagnostics:
  The issue can be confirmed with service tracing or dump file
  analysis.
  
  Service tracing will show rc = 7105 being returned by
  WMIProperty::GetProperty and VMID=(null) being returned by
  WMIVirtualMachineCluster::GetClusteredVirtualMachines()
  
  SERVICE TRACE example:
  <DATE/TIME STAMP> [XXXX][YYYY] : ..\..\common\winnt\wmiutil.cpp
    (2036): WMIProperty::GetProperty(dsChar_t**): Get buffer of
    data failed use IWbemClassObject
  <DATE/TIME STAMP> [XXXX][YYYY] : ..\..\common\winnt\wmiutil.cpp
    (1966): EXIT  <===== WMIProperty::GetProperty(dsChar_t**),
    rc = 7105
  <DATE/TIME STAMP> [XXXX][YYYY] : ..\..\common\winnt\cluswmi.cpp
    ( 315):
    WMIVirtualMachineCluster::GetClusteredVirtualMachines() Found
    VMID=(null) in cluster group=dcprdssmng01
  
  Dump file analysis will return this CALLSTACK:
