    Adding Data Nodes to an Active SSR Cluster (SRC CLI)

    Note: This procedure makes the following assumptions:

    • You are working with an active cluster and the SSR database is in production mode. If you are unsure what mode the database is in, see Viewing the SSR Database Mode (SRC CLI)
    • Your SSR cluster currently only has two data nodes.
    • You have physically installed the two additional C Series Controllers that will be acting as data nodes, made the interface connections to the cluster, and installed the SRC software.

    Caution: Changing the cluster geometry causes the SSR database to be destroyed. All data will be lost and you need to re-create the database. This procedure should be performed only during a maintenance window. Review this procedure in full before proceeding.

    To add data nodes to an active cluster:

    1. Configure each of the C Series Controllers as data nodes.

      See Configuring the Nodes in the SSR Cluster (SRC CLI).

    2. Change the SSR cluster geometry to four-data-node.

      See Configuring the SSR Cluster Geometry (SRC CLI).

    3. Commit the configuration.

      See Committing a Configuration and Exiting Configuration Mode.

    4. Place the database into maintenance mode.

      See Placing the SSR Database into Maintenance Mode (SRC CLI).

    5. Disable the component database on each management server in the cluster (one by one).

      See Disabling the SSR Database (SRC CLI).

    6. Enable the component database on each management server in the cluster (one by one).

      See Enabling the SSR Database (SRC CLI).

    7. Restart the component database on each of the existing data nodes (one by one).

      See Restarting the SSR Database (SRC CLI).

    8. Enable the component database on each of the new data nodes (one by one).

      See Enabling the SSR Database (SRC CLI).

    9. Verify the cluster configuration changes by viewing the status of the database.

      See Viewing the Status of the SSR Cluster (SRC CLI).

    10. Re-create the SSR database.

      See Creating the SSR Database (SRC CLI).

    11. Restart all SSR client components.

      See Enabling SRC Components

    12. Place the database into production mode.

      See Placing the SSR Database into Production Mode (SRC CLI).
