Keywords:
Load sharing media server clusters can provide continuous access to services during updates, when you update one server at a time.
The Primary and Secondary nodes in the cluster require special consideration during the update, since these nodes have master Content Store components on them serving the data needs of the entire cluster. To provide continuous content access, either the Primary or Secondary server must remain in service during the updates. Standard nodes can only connect to Primary or Secondary servers on the same software release. To ensure that the Standard nodes have a connection to a Primary or Secondary server on the same release during the cluster update, the Primary is updated first and the Secondary server is updated last.
Use this procedure to update N+1 load sharing clusters.
  1. To update the Primary server, use the procedure for Installing an update.
    ADDITIONAL INFORMATION:
    Wait for any alarms to clear as the server returns to service after the upgrade.
  2. To upgrade each Standard server, use the procedure for Installing an update.
    ADDITIONAL INFORMATION:
    Wait for any alarms to clear as the server returns to service after the upgrade.
  3. To upgrade the Secondary server, use the procedure for Installing an update.
  4. Verify the success of the installation.
    ADDITIONAL INFORMATION:
    Check for any service-impacting alarms and perform a test of the system. For example, place a call to an application, and verify all the nodes in the cluster receive calls.
