Failing over application workloads configured for
DNS failover

When a failover condition has been met, failover will be triggered automatically if you
configured automatic failover when establishing protection. If you configured manual
intervention before failover, you can use the Application Manager to initiate failover for
application workloads configured for DNS failover.

Note: In a clustered environment where the source suddenly becomes unavailable (for

example, it crashes) and the Application Manager is open, it may appear to be
unresponsive for up to 30 minutes before the failover process continues. The
Application Manager is waiting on a Microsoft cluster file to respond. To reduce
the amount of time before failover can continue, close and re-open the
Application Manager.

If you are protecting a file server, failover is only available if the source is offline,
in order to prevent name conflicts on the network.

1. If you are protecting a standalone BlackBerry server with Exchange or SQL,

shutdown the BlackBerry server.

2. In the Application Manager, make sure your source target pair is selected and then

on the Monitor tab, click Failover.
