How can Hyper-V guest connect to Cluster Shared Volume?

We have 2 Dell servers in a cluster. The servers are running Server 2012 Datacenter. There are 13 or 14 Hyper-V guests.

We have Dell AppAssure running on one of the hosts (which Dell installed and configured), but it's not behaving properly, and in fact if one of the clusters goes offline, AppAssure somehow stops the guests from coming back online, and the only way to get them to start up is to stop the AppAssure services.

The AppAssure repository is on a cluster shared volume.

A Dell technician yesterday said that ideally, the AppAssure software should be running on it's own Hyper-V guest. I have a guest ready to go, but I need this guest to be able to access the same Cluster Shared Volume for the repository, and I am unsure of how to do this.

Any help would be appreciated.

Is it possible to replace your repository into your VM?
Chris MillardAuthor Commented:
Well, I could, but the Dell rep suggested doing it this way (for whatever reason).

What is the repo doing on csv? It seems to me csv is supported only for hyper-v.

That's what Dell set up!
A KarelinCommented:
Interesting. Dell does not recommend running the AppAssure Core on the same physical machine that serves as the Hyper-V host. (This recommendation does not apply to Dell backup and recovery appliances.)
Ok. Do you have DAS, NAS or SAN? Can you create LUN on this and attach to the VM? The APP can use the repo, but the repo will not into vhd disks.

CSV is for VHDX files only as storage management and arbitration at the cluster level is not set up to handle any live app data on CSV.

Your AppAssure VM needs to have a second VHDX for data. That's where your AppAssure structures can be installed.

AppAssure is maintaining file locks outside of the cluster service and thus the CSV failure.
Chris MillardAuthor Commented:
I have created a new fixed size VHDX on the CSV and and attached that to the Hyper-V host.
