These errors do seem most relevant to the issue and would probably cause it, although the P4300 supports SCSI-3 as far as I can tell. To function properly with failover clusters.

Successfully issued call to Persistent Reservation REGISTER using Results of a 'Validate Cluster' only brought back the following relevant errors: There doesn't appear to be any information regarding Online (No Access) on the internet, so any information at all would be very much appreciated right now. To further confuse things, enabling 'Maintenance Mode' on the disk changes the status to Online (Maintenance Mode) and the disk now appears in C:\ClusterStorage (on the node where the cluster disk is located) and allows read/write access just fine. There are no errors or warnings in the log and the only informational message is that the disk was brought online.

They do not appear in C:\ClusterStorage as they should on either of the member nodes.

The issue is that when we add the Cluster Disk (which initially reports as Online with 'Available Storage' status) as a Cluster Shared Volume, it briefly reports as Online until reverting to Online (No Access).

We have also installed the HP P4000 DSM which is also working fine (this is on one of the Hyper-V nodes and has full access to the disk). We have Shared Storage (HP P4300) which is reporting no errors and is working just fine as either a standalone disk or witness disk within the cluster. We have a Hyper-V 3.0 Failover Cluster (2 servers) each running Windows Server 2012 RC.
