To switch an application to another system
If you want to gracefully stop an application on one system and start it on another system in the same cluster, you must use the Switch link. You can switch the application only to a system where it is not running.
Note that the Switch link is dimmed in the following cases:
If you have not configured any application components for monitoring
If you have not specified any failover system for the selected application
If the application is in maintenance mode
If no system exists in the cluster, where the application can be switched
If the application is not in online or partial state on even a single system in the cluster
To switch an application
- In the appropriate row of the application table, click Switch.
- If you want VCS to decide to which system the application must switch, based on policies, then in the Switch Application panel, click Any system, and then click OK.
To learn more about policies, see the Cluster Server Administrator's Guide.
If you want to specify the system where you want to switch the application, click User selected system, and then click the appropriate system, and then click OK.
Cluster Server stops the application on the system where the application is running, and starts it on the system you specified.
