Passthrough Disk in Hyper-V Cluster

having problem how correctly pass disk child vm host's san disks hyper-v hosts being clustered.


hyper-v cluster
each node has access san luns
two vm's configured high availability
each vm has lun on san dedicated chld vm's virtual hard disk boot.
each vm needs to have access same physical lun on san sql data storage these vm's clustered within hyper-v level.

essentially, need cluster 2 vm's sql servers , have access physical san luns sql data.

problem:

how configure passthrough disk @ host level when suppose offline in clustered configuration?  configuration shows errors in failover cluster status passthrough disks. 

what best practice configuration?

additional info:

i'm trying setup passthrough disk directly vm un-managed within host failover clustering.  assume disk available of host nodes @ anytime failover cluster between 2 vm's manage ownership of lun directly.  prevent host failover cluster management showing errors b/c disk offline (a requirement @ host level). the problem configuration other vm's cannot start when passthrough disk online within 1 of other vm's. 





thanks in advance

i have discovered in order guest based clustering of vm's, source luns must via iscsi , not fiber channel.  rtm release prevents me attempting use fc disks guest vm's cluster disks.  articles below states disks must iscsi.  major limitation me, msft => please add capability !
