NOTE: The SMS monitors the need to synchronize the cluster nodes. In typical operations, you will not need to synchronize; however, when you manually failover a cluster node or take one of the nodes offline, you need to resynchronize the SMS cluster.
Procedure:
- Log in to the SMS from a client.
- On the SMS toolbar, navigate to the Admin option.
- In the Admin workspace, select High Availability in the navigation pane.
- In the HA Cluster Status area, click Synchronize.
- In the dialog box, choose to include or exclude historical event data from the synchronization. Select the synchronization source, the default source, the most recent active SMS server (before failure), or specify another source from the drop-down list.
