Upgrading the S Nodes in the Cluster

To perform a rolling restart upgrade in S nodes of your cluster, install the new software and configure it on each S node in the cluster.

Note: Execute this procedure on each S node, one at a time. This example procedure uses one S node bng-sbrha-1 (10.212.10.65).

Installing the New SBRC Software on the S Node

Execute the following steps to install the new SBRC software package on the S node:

  1. Stop the RADIUS process in the S node.

    Execute:
    root@bng-sbrha-1: /opt/JNPRsbr/radius/sbrd stop radius

    Stopping radius server processes
    waiting for radius
    10 seconds elapsed, still waiting
    radius stopped
    

    Log in to a M node and execute ./sbrd status. Verify that the S node is disconnected from the other nodes.

    Execute:
    root@bng-mars: /opt/JNPRsbr/radius/sbrd status

  4. Move your original installation to a different location to prevent the removal of files. Be sure not to move the /opt/JNPRshare directory, which should contain your original cluster configuration files. For example, if you previously installed Release 7.6.0, execute the following as root:
    1. Navigate to the opt directory: root@bng-sbrha-1: cd /opt.
    2. Create a new directory: root@bng-sbrha-1: mkdir 760.
    3. Move the configuration files to the new directory: root@bng-sbrha-1: mv JNPRsbr JNPRmysql JNPRmysqld JNPRhadm JNPRndb_mgmd JNPRndbd 760.
    4. Remove the old software package: root@bng-sbrha-1: pkgrm JNPRsbr.
  5. Install the new SBRC software distribution package.

    Execute:
    root@bng-sbrha-1: cd /opt/tmp pkgadd –d

    The following packages are available:
      1  JNPRsbr.pkg     JNPRsbr - Juniper Networks Steel-Belted Radius (Carrier Cluster Edition)
                         (sparc) 8.30.50242

  7. Once the system displays the message Installation of JNPRsbr.pkg was successful, repeat this procedure on the next S node. Once the new software is installed on each S node, proceed to Configuring the New SBRC Software on the S Node.

Configuring the New SBRC Software on the S Node

Configure the new software on each S node, one at a time:

  1. Configure the SBRC software on the S node, using the original cluster configuration files.

  5. Migrate the configuration from your previous software release to the new software package. In most cases, you simply need to identify your previous installation. In this example, the cluster configuration is named configure.6node_cluster.tar (see the previous step), and is stored in the /opt/JNPRsbr/radius/install directory. Once you specify the configuration, SBRC migrates your configuration.
