"Unsupported cluster configuration" VMM

Applies to:

System Center Virtual Machine Manager (SCVMM) CB (2016)

Windows Server 2016

Hyper-V 2016

In Virtual Machine Manager (VMM), the VM’s show up as "Unsupported cluster configuration".

The following WMI query

gwmi -Namespace root/microsoft/windows/storage -class MSFT_PhysicalDisk

would return a blank value.

gwmi -class Win32_diskdrive

would return a value.

So it was specific to the Namespace root/microsoft/windows/storage and class MSFT_PhysicalDisk.

WMI repository was fine.

WMI-activity debug logging didn't show anything, because it handed off the COM call to the other process.

A debug by Michael Sadoff (WinDbg) showed that it was querying a "Storage service".


"Microsoft Storage Spaces SMP" service was set to disabled.

Note:  SMP == Storage Management Provider.


The "Microsoft Storage Spaces SMP" service should be set to Manual and started. (The default value).

Moral of the story:

One more reason to be careful about what services to disable.

P.S.  My colleague Chuck Timon also had another scenario where the same error had popped up, and how he went about troubleshooting:
