Synchronize the SMS HA cluster to restore the cluster to a fully-functional state. Synchronizing the cluster synchronizes the database and configuration files to the passive server and restores the primary SMS to active status. When you synchronize the SMS HA cluster, the SMS client is temporarily disconnected while the SMS server on each node in the cluster automatically restarts.

Before you begin

Before performing a synchronization, investigate and resolve any server-related issues on the primary SMS server that may have resulted in an automatic failover to the secondary node.
When investigating SMS server issues, consider the following:
  • The number of managed devices
  • The rate at which the SMS server receives device events
  • Profile distribution
  • DV distribution

Procedure

  1. On the HA Cluster Status panel, click Synchronize.
    If the Synchronize button is disabled, it is not necessary to perform a synchronization.
  2. Choose to include, or not include, historical event data in the synchronization.
    Note
    Note
    If you include historical event data, depending on the size of your event database, it can take hours to synchronize the cluster.
  3. Select the synchronization source, either the default source which is the most recent active SMS server or specify another source from the drop-down list.
  4. Click OK.
    When the synchronization completes, the IP address of the original primary SMS appears under the Active SMS group with a status of Active.
