I'm in the process of setting up a new cluster using Windows Server 2012 with a view to migrate from our existing 2008 R2 cluster. I am having problems validating the storage and the wizard keeps failing on the List All Potential Cluster Disks test (which causes all the other storage tests to be cancelled).
I'm getting the following error:
Failed while verifying removal of any Persistent Reservation on physical disk 19ba99a4 at node RC-HYPERV-3.riddlesdown.local.
When I look in validation report, disk 19ba99a4 is the management LUN (Access LUN 31 as termed by the storage software).
Looking on my 2008 R2 cluster this doesn't appear in Disk Management.
Any ideas how I can get rid of it or the error that it is causing?
