I have a new Hyper-V 2012 R2 cluster with 4 physical hosts and management done by a 5th physical server with SCVMM 2012 R2. The storage on the Hyper-V cluster is clustered storage spaces (with SAS JBODs) on form of CSVs. All hardware is certified by Microsoft to this solution. Cluster validation in Failover Cluster passes on all tests. All servers are patched til last update.
Problem: In VMM 2012 R2 I cannot do live and storage migrations. They allways end with:
Error (20404)
VMM cannot find a required object.
Recommended Action
Ensure the object is valid, and then try the operation again.
If I run the same storage and live migrations on the Failover Cluster in the Hyper-V hosts, they all succeed.
