How do I configure the SMS for High Availability (HA) ?

The SMS can be configured to operate in a two-node cluster, increasing availability of the SMS server should an unexpected event cause one of the nodes to fail or become inaccessible.

SMS HA Administration Concepts and Planning

The most important aspects of the SMS HA cluster are the heartbeat connection and database replication. Periodically, verify that both activities are performing as expected. If you need to upgrade SMS software or apply an SMS patch, you must break apart the cluster and upgrade, or patch, each of the two SMS HA cluster nodes independently. The reason for this is that one of the nodes is always passive and therefore the SMS software is not fully operational and cannot be upgraded or patched. If you need to perform maintenance on the active SMS server, for example to swap out a network card, you can invoke a fail over on the active node, which deactivates it and activates the passive SMS server. Once deactivated you can take the node offline, power it off, and perform maintenance on it. 

HA Cluster Status

In the HA Cluster Status area of the High Availability screen, you can view the current status of the SMS HA cluster, view the management IP address and network of the SMS cluster. As well, you can configure and set up a new SMS HA cluster. 

How To: Configure an SMS HA Cluster

  1. Log in to the SMS from a client.
  2. On the SMS toolbar, navigate to the Admin→High Availability tab.
  3. In the HA Cluster Status area, click Configure. The SMS High Availability Wizard opens.
  4. Read the Welcome screen and click Next.
  5. Choose the network configuration for your SMS HA cluster. If you want all communications to occur over a single network, choose Primary Only. If you want replication and heartbeat signals to occur over a secondary, intra-cluster, network path, choose Primary and Secondary.
  6. Click Next.
  7. If you want to use a Shared Virtual Management IP address, check the check box and enter the IP address. Selecting this option requires that the Shared Virtual Management IP address and the Maintenance IP addresses of the active and passive SMS servers be in the same subnet.
  8. Enter the maintenance IP address of the SMS system you are designating as the passive SMS server.
  9. Click Next.
  10. If you chose the Primary and Secondary network configuration, enter the secondary IP addresses for both the active and passive SMS servers. If you do not require the IP addresses to reside in the same subnet, uncheck the check box and provide gateway IP addresses for the active and passive SMS servers.
  11. Click Next.
  12. Enter the login credentials for the passive SMS server. The credentials must be those of a user with SuperUser rights.
  13. Click Configure. The Configuration Status dialog box opens and displays ongoing status. When the configuration finishes, the HA Cluster Synchronization dialog box opens.
  14. You must synchronize the SMS databases that exist on the two SMS cluster nodes. The source and destination server IP addresses are shown. Check the check box for Synchronize the HA cluster. You can include all historical event data by checking the check box: Include historical event data.
  15. Click Finish.
  16. A dialog box opens stating that the client connection to the SMS server is lost. All client connections are disconnected because access to the SMS database is prohibited during the synchronization process. To monitor progress, click More. The HA Synchronization Status dialog box opens, displaying a progress bar, time elapsed, and so on.
  17. When synchronization finishes, the SMS client automatically attempts to reestablish a connection with the active SMS server. When the connection is reestablished, the SMS client opens to the Admin - High Availability screen.
  18. Verify the operational state of the cluster by ensuring the Active SMS status displays Active and the Passive SMS status displays Passive. If you chose the Primary and Secondary network configuration, verify that the Heartbeat IP addresses for each SMS cluster node are as expected.
