Passthrough Disk in Hyper-V Cluster

[guest]

Having a problem with how to correctly pass a disk to the child VM from the host's SAN disks with the Hyper-v hosts being clustered.


Hyper-V Cluster
Each node has access to SAN LUNs
Two VM's are configured for high availability
Each VM has a LUN on the SAN dedicated for the chld vm's virtual hard disk to boot.
Each VM needs to have access to the same physical LUN on the SAN for SQL Data storage as these VM's will be clustered within the Hyper-V level.

Essentially, I need to cluster two VM's as SQL Servers and they would have access to PHYSICAL SAN LUNs for SQL Data.

Problem:

How do I configure the passthrough disk at the host level when it is suppose to be OFFLINE but also in the clustered configuration? This configuration shows errors in the failover cluster status for the passthrough disks.

What is best practice for this configuration?

Additional Info:

I'm also trying to setup the passthrough disk directly to the VM un-managed within the host Failover Clustering. I assume that the disk will be available by any of the host nodes at anytime thus the failover cluster between the two VM's will manage the ownership of the LUN directly. This would prevent the Host Failover Cluster management from showing errors b/c the disk is offline (a requirement at the host level). The problem with this configuration is that the other VM's cannot start when the passthrough disk is ONLINE within one of the other VM's.

I have just discovered that in order to do the guest based clustering of VM's, the source LUNs must be via iSCSI and not Fiber Channel. The RTM release now prevents me from attempting to use the FC disks for the guest VM's cluster disks. The articles below states that the disks must be iSCSI. This is a major limitation for me, MSFT => Please add this capability !
