You can manage DFS namespaces through a dedicated job type in Peer Management Center, the DFS-N Management job. Peer Management Center controls failover and failback by automatically disabling and enabling DFS namespace folder targets.
Peer Management Center and Agents are constantly looking for connectivity issues and other failures across linked file servers, the Peer Agents themselves, and entire sites. If Peer Management Center detects a failure, it can be set to automatically disable a linked DFS namespace folder target from a namespace folder. This will prevent end users from accessing the associated folder target. If configured to do so, DFS Namespaces will automatically redirect clients to another available folder target.
While DFS Namespaces itself can automate the disabling of folder targets, it does not automate the re-enabling of disabled targets. When configured to talk to DFS namespaces, Peer Management Center can automate this process. When Peer Management Center determines that a file server, Peer Agent, or entire site is back online, it automatically runs the following process to re-integrate that file server:
1.Kicks off a rescan to ensure the disconnected site or file server is brought back in sync with the others.
2.Re-enables the associated folder target once the re-scan is complete. Once this is done, DFS Namespaces begins to direct end users back to this file server.
