Configuring failover service

To configure the failover service, configure backup servers as follows:

1. Create the Failover service object on the basis of the Computer object corresponding to the backup server on the Hardware tab of the System settings window.
   
2. Go to the settings panel for the Failover service object.
   
3. From the Monitor PC drop-down list, select the name of the Computer object the connection with which must be controlled.
4. In the Wait for reconnection (s) field, specify the time period in seconds after which the configuration is transferred to the backup server since the server connection fails.
   

   Note

   The Time left string is automatically filled in depending on the remaining time: if there is less than one day left before reconnection, the number of hours is displayed (for example, Time left 5 hours). If less than one hour—number of minutes (for example, Time left 5 minutes). If less than one minute—number of seconds (for example, Time left 0 seconds).

5. To transfer the configuration without ping from the main server, set the Transfer if no ping checkbox.
6. In the Objects table, specify the list of configuration objects of the main server that must be transferred to the backup server if connection fails in one of the following ways:
   
   1. Manually, one by one:
      

      1.  From the Type drop-down list, select the object type.

         Note

         You cannot select the Manager of failover services object type. These objects aren't transferred to the backup servers, as each backup server must have its own Manager of failover services.

      2. From the Number drop-down list, select the object ID.
      3. The Name field is automatically filled in with the name of a corresponding object.

      4. Repeat steps for all objects in the objects tree of the controlled server that must be transferred to the backup server if the connection fails.

         Note

         To add a new line in the table, click the downwards ↓ button on the keyboard.
      5. Click the Apply button.
   2. As a group:
      
      1. Click the Range button. The Range window is displayed.
         

      2. From the drop-down list, select the object type.

         Note

         You cannot select the Manager of failover services object type. These objects aren't transferred to the backup servers, as each backup server must have its own Manager of failover services.

      3. In the table, mark the required objects of this type. To mark several objects, hold the Ctrl key on the keyboard.

      4. Click the button to move the selected objects to the list of the monitored objects that is located in the right part of the Range window.

         Note

         The button is used to move the object back from the list of the monitored objects to the list of the available ones.
      5. Repeat steps for all required objects.
      6. Click the OK button.
      7. Click the Apply button.
7. Repeat steps 1—6 for all main servers in the distributed system that will be controlled by the configured backup server.

Configuring the failover service is complete.
