Goal This article has the goal that help the readers to make such a Distributed File System, where the replication occurs between a DFS and a Failover File Cluster share. In this article I will use NetApp DataOntApp 8.x 7-mode for the storage and Microsoft Windows Server 2008 R2 Enterprise for DFS and FailOver Cluster. This is how it looks like.
DATA Namespace DFS-R with the HOME Folder with Target
Requirements First, create the three Windows Server and the NetApp. I name them to DC, FS, Cluster2 and Netapp. DC holds the AD, DNS, DFS, DHCP roles. The FS and Cluster2 will be the two nodes of the cluster where Cluster, File service and DFS features are installed. The nodes have two NICs.
NetApp CIFS share can not be used with DFS-R! Only Windows 2008 mode can be used when FailOver Cluster is the replication target.
Netapp IP address: 192.168.206.150
DC IP address: 192.168.206.181
Cluster IP networks: 192.168.206.0/24 and 192.168.48.0/24.
FS IP addresses: 192.168.206.100 and 192.168.48.133
Cluster2 IP addresses: 192.168.206.155 and 192.168.48.134
Cluster from client 192.168.206.200 and 192.168.48.100 for the heartbeat.
There are three LUN: a quorum (witness) disk and a shared disk for cluster, and a disk for DFS share. You can use one aggregate for the disks, I used three different just to exercise.
![Page 4: Domain-based DFS with Failover Cluster replication targetblackwombat.com/cikkek/pdf/DFS_Cluster_NetApp.pdf · Goal This article has the goal that help the readers to make such a Distributed](https://reader031.vdocuments.us/reader031/viewer/2022030613/5add98057f8b9ae1408d316c/html5/thumbnails/4.jpg)
Creating a LUN to the Failover Cluster Login to NetApp Controller and Choose the Aggregates.
Click Create.
I give the aggr_cluster name to the aggregate.

I have just choosen what I got, because of the limitation.
Click on the Select Disks and give 8 disks.

Here you will see how does it look like.
What will be created is shown for us. It takes a lot of time in the virtualized environment to zeroing the disks. You can click on the Finish, it will do it int he background. We can see when it is finished. It have taken for me about an hour.

Create the Initiator Group for the LUN
Choose the LUNs and Initiator Groups. Click on Create to the Wizard. Name it to Win and choose Windows for the Operating System and iSCSI. We will add the nodes of cluster to it.
Create the LUN
Choose the LUNs. Click ont he Create to execute the wizard.

I gave the name lun_cluster to the disk of cluster. It is 4GB and Windows type.
Choose the Create a new felxible volume in, which will automatically create the LUN on the above created aggregate.

Let’s create it. Click Create.
Creating the Failover File Cluster First I have to add the two nodes to the Win Initiator Group. On the NetApp choose the LUNs, then Initiator Groups tab. Click Create button. Click ont he Initiators tab.
![Page 13: Domain-based DFS with Failover Cluster replication targetblackwombat.com/cikkek/pdf/DFS_Cluster_NetApp.pdf · Goal This article has the goal that help the readers to make such a Distributed](https://reader031.vdocuments.us/reader031/viewer/2022030613/5add98057f8b9ae1408d316c/html5/thumbnails/13.jpg)
Run the iSCSI Initiator from Start->Administrative Tools to determine the Initiator Name. Do this on the two nodes.
You can see the two nodes initatior names from the cluster. Click Save and Close.
Now connect to the NetApp to get the LUN.
