Adding Client 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).

  • You have physically installed the new C Series Controllers that will be acting as a client node, made the interface connections to the cluster, and installed the SRC software.

Caution

This procedure requires you to restart the management servers in the cluster, which is a disruptive process. This procedure should be performed only during a maintenance window. Review this procedure in full before proceeding.

To add a client node to an active cluster:

  1. Configure the C Series Controller as a client node.

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

  2. (Optional) Configure the new client node to host a management server.

    See Configuring the Management Servers in the SSR Cluster (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. (Optional) If the new client node is hosting a management server, you need to restart the component database and all SSR client components on all client nodes in the cluster (one by one). If the new client node is not hosting a management server, this step is not necessary.

    See Restarting the SSR Database (SRC CLI).

    See Enabling SRC Components.

  8. Enable the component database on the new client node. If you have added more than one client node, perform this step on each new client node (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. Place the database into production mode.

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