Hyper V Cluster - Cannot create VM

I created a LUN on my SAN.

I then added the disk to the cluster in failover cluster manager. Its online and looks perfect.

I then went into VMM and added it to the available storage.

When I create a new VM in VMM it will not let me put a VHD on that disk. The disk doesn't even show.

Any ideas?

can the host/node see the clustered storage location directly?

Yes it can.

I have also tested copying data to and from the disk.

Any ideas?

The disk is online in Cluster Failover Manager.
The host it is assigned to can see it.
Permissions on this disk are the same as all the other disks.
Restarted both hosts in the cluster and the management server.

Disk is still good in Cluster Manager.

VMM still doesn't make it available for new VMs even though it is there under available storage.

how odd.
could you creat a new VM on another node and then try to live-migrate it to this node to see if it can access an existing VM on the disk?

I was trying to do this because I couldn't see the disk via P2V. it was just quicker to test this way. If I set the properties to highly available, I then could see the disk. School boy error.

But, there is a bug on VMM where you can only see local disk when doing a P2V and only being presented with local disk:
