I currently have a 2 node 2008 R2 hyper-v cluster. I just purchased 2 brand new servers on which I've installed 2012 R2 and set up my new target cluster there.
I'm using a Dell MD3200i iSCSI SAN as storage.
My Hyper-V 2008 R2 SAN still sees the LUN's. the 2012 servers see the LUN's in disk management but the drives show "offline". They do not appear in the storage view in the Failover Cluster Manager. If I try to "Add Disk", it tells me I have no suitable drives for cluster disk.
It is my understanding that I can have two clusters access the same disk in order to migrate the VM's and cluster roles over, using the cluster migration tool found in failover cluster manager. A Microsoft tech at Dell told me this would be possible as well.
Am I wrong and going about this wrong?
