KB: "Error 26184" when you assign a LUN to a cluster in System Center Virtual Machine Manager 2012 SP1

Assume that you're using an IBM Storwize V3700 device in a Microsoft System Center Virtual Machine Manager 2012 Service Pack 1 (SP1) environment. When you try to assign a logical unit number (LUN) to a cluster, you receive the following error message:

Error 26184 The existing storage group for null does not match the storage group for null. Make sure the storage group setting at the storage array matches the storage groups created for the cluster.
