Preparation for setting up FSA services in a cluster

Before you set up the FSA clustering feature, do the following:

We recommend that you place the Enterprise Vault Administration Console and the target file servers in the same domain. If you place the Vault Administration Console and the target file servers in separate domains, you must set up a domain trust relationship.
If you intend to set up a single-node cluster, you must first create the registry value SingleNodeFSA on the computer that runs the Administration Console. Create SingleNodeFSA under the following registry key, and give it a DWORD value of 1:
```
HKEY_LOCAL_MACHINE
 \SOFTWARE
  \KVS
   \Enterprise Vault
	\FSA
```
If you want to set up a single-node cluster, create this registry value before you do either of the following:
- Install the FSA Agent on the file server, if you perform this task from the Administration Console.
- Run the FSA Cluster Configuration wizard.
For more information on SingleNodeFSA, see its entry in the Registry Values guide.
Ensure that the cluster group to which you want to add the FSA services resource also has a shared disk resource (sometimes referred to as a physical disk resource or Mount/MountV resource). Only Veritas or Microsoft Cluster Server groups for which you have configured a shared disk resource are available for selection when you run the FSA Cluster Configuration wizard.
For VCS configurations, make sure that the Public network connection is set as the top connection in the Connections list. Do this procedure on each node in the cluster that is to include FSA services.

To ensure that the Public network is the top entry in the Connections list of each node

On a node that is to include FSA services, right-click My Network Places, and then click Properties.
On the Advanced menu, click Advanced Settings.
On the Adapters and Bindings tab, ensure that the Public network is the top entry in the Connections list.
Repeat steps 1 to 3 for each node that is to include FSA services.
