Unsupported Cluster Configuration
Recently I was asked why when using a Geo. Cluster configuration with Hyper-V (in this instance two HP EVA Arrays with StorageWorks Cluster Extension (CLX)) the clusters show up as not supported in SCVMM 2008.
The issue is SCVMM 2008 doesn’t support CLX (actually HP isn’t the only vendor with this cosmetic issue, any Geo. Cluster solution is impacted, and I have seen this on EMC's SRDF as well).
CLX requires you to create a new resource inside the VMs Cluster Resource Group and set a dependency between the disk and the new CLX resource. However SCVMM detects the CLX resource inside the VMs cluster resource group, blocks support for this, and so the VMs state change to “unsupported cluster configuration”
The problem is also well documented externally at http://social.technet.microsoft.com/forums/en-US/virtualmachinemgrclustering/thread/1e0b803c-1da1-40a5-8e26-d3770f142a5a/
In my opinion it is unlikely that we will see a hot fix to resolve this issue anytime soon and that any hot fix planned would be rolled up into SCVMM 2008 R2.
