Shadow Copy in a Cluster

Microsoft states - "If you have multiple shadow copy volumes, use a single, separate disk for the storage volume. "

Ok, and makes sense.  I have 3 shared disks in my cluster (G: and H: are production data and F: is dedicated for shadow copies).  When I setup Shadow Copies through the disk properties, I don't have the option to select a differnet Data Location.  How can I setup both of my production disks G: and H:) to Shadow Copy to my 3rd disk (F:)?

Thanks

Here's what I am not understanding.  Micorsoft states the Storage Data vulume is directly related to the shared disk and must reside in the same group.  So, if I have a seperate cluster group for my shared diskes, how can I place the shadow copies on the same disk?  A physical disk cant' reside in more than one group.  I tested by creating a new disk and I was able to configure shadow copy for one of my cluster groups that stores the data on this new disk.  But, the kicker is, now that I have configure one of my cluster groups to store the shadow copy files on a seperate disk, I can't configure my other cluster group to use the same setup.  Almost sounds as if you have to have all resources in one group.  

Any help would be appreciated.

I haven't done this myself, but it makes sense to me that any disk resources used for shadow copy would have to be in the same cluster resource group as the data volumes.   I don't see how the shadow copy mechanism could work unless the data volumes and shadow copy volumes were guaranteed to be running on the same system.

So, if you have multiple data disks and want to use a single shadow copy volume all resources will have to be in the same cluster group.      If you have four or more data disks then you could divide the data disks into two groups with a seperate shadow copy disk in each group.
