FIX: Virtual Machine Manager crashes when you try to manage a mirror LUN on a secondary storage array in Windows Server 2012

Á við um: Windows Server 2012 DatacenterSystem Center 2012 Virtual Machine ManagerWindows Server 2012 Datacenter

Symptoms


Consider the following scenario:
  • You run Microsoft System Center 2012 Virtual Machine Manager Service Pack 1 on Windows Server 2012.
  • You have two EMC Storage Area Network (SAN) storage arrays that are managed by one EMC Storage Management Initiative Specification (SMI-S) provider.
  • You create one logical unit number (LUN) on the first SAN storage array and the additional mirror LUN on the secondary SAN storage array in Virtual Machine Manager.
  • You try to manage the mirror LUN on the secondary storage array in Virtual Machine Manager.

In this scenario, Virtual Machine Manager crashes.

Cause


This problem occurs because Virtual Machine Manager does not handle the LUNs from more than one storage array when the LUN ID on the first LUN is the same on both storage arrays. Virtual Machine Manager does not understand which storage array each LUN belongs to.
