This subsection describes how to start the system when you are using the N-to-1 recovery system.

To use the N-to-1 recovery system, you must start the Management Server beforehand. Start the Management Server if you have not yet started. For details on how to start Management Server, see 4.1.1 Procedure for starting a system and 4.1.2 Methods of starting a system in the uCosminexus Application Server Management Portal User Guide.

Furthermore, in the N-to-1 recovery system, the node that you start first operates as the executing node and the node that you start later operates as the standby node. Always start the active node before the spare node.

The following is the procedure to start the N-to-1 recovery system:

1. From the Start menu, select Control Panel - Performance and Maintenance - Management Tools, and then select Cluster Administrator.
   The Cluster Administrator starts.
   
2. In the console tree (left pane), select an active node, and then from the File menu, choose Start Cluster Service.
   The cluster service of the selected active node starts. Execute this step for all active nodes.
   
3. In the console tree (left pane), select the spare node, and then from the File menu, choose Start Cluster Service.
   The cluster service of the spare node starts.
   
4. In the console tree (left pane), select a resource group that contains an active node and the spare node, and then from the File menu, choose Set to Online.
   The selected resource group goes online. Execute this step for all resource groups.
   
5. Start each logical server of the executing node host.
   For details on how to start the logical servers, see 4.1.2 Methods of starting a system in the uCosminexus Application Server Management Portal User Guide.
