KBJust an FYI on a new System Center Virtual Machine Manager Knowledge Base article we published this morning:

=====

Summary

When you attach a GPT pass-through disk provided from SAS storage (Serial attached SCSI) to a highly available virtual machine by using the Hyper-V Manager or Failover Cluster Management Microsoft Management Console (MMC) snap-in, the System Center Virtual Machine Manager 2008 Admin Console lists the status of the virtual machine as "Unsupported Cluster Configuration."

Details on the High Availability section of the VMs Properties in SCVMM are:

Highly available virtual machine <Machinename> is not supported by VMM because the VM uses non-clustered storage. Ensure that all of the files and pass-through disks belonging to the VM reside on highly available storage.

More Information

GPT pass-through disks provided from SAS storage are not supported in System Center Virtual Machine Manager 2008 R2.
