Cleaning the Transition Server

To free the licenses used by the transition server, and clean up installed software, uninstall the SBR Carrier software. See Uninstalling Steel-Belted Radius Carrier Software.

1. Log in as root.
2. Navigate to the directory where you installed the Steel-Belted Radius Carrier package, usually /opt/JNPRsbr. Then, navigate to the radius/install subdirectory.
3. Stop the RADIUS processes.

Execute:
./sbrd stop radius

4. Stop the ssr processes:

./sbrd stop ssr

5. Run the configure script:

Execute:
./configure

6. From the menu of configuration tasks, enter 1 to specify Unconfigure Cluster Node.

Configuring SBR Software

---------------------------------------------------------------------------

SBR 7.20.4744 cluster 

on SunOS 5.10 Generic_120011-14 node sbrha-4

is not configured and processes are down, needs to be configured

---------------------------------------------------------------------------

1.  Unconfigure Cluster Node

        Not used when merely updating existing cluster definitions.

2.  Generate Cluster Definition

        Creates new or updates existing cluster definitions.

        Modifies the shared directory but does not modify this node.

3.  Configure Cluster Node

        To be preceded by 'Generate Cluster Definition' on any node.

        Must be invoked on each and every node of the cluster.

4.  Reconfigure RADIUS Server

        Only on SBR nodes, updates the existing SBR configuration.

5.  Create Temporary Cluster

        Used to approximate a cluster using only this one machine.

        Intended for migration and demonstration purposes only.

Enter the number of the desired conifguration task or quit (2,q): 1

7. A warning message is displayed. Enter y to proceed.

8. Clean up the user accounts.

A prompt is displayed to delete or preserve and clean up the hadm user account and associated directories.

• If you are going to reconfigure this server to serve as a stand-alone SBR Carrier server or become a node host in a cluster, enter n.
• If you want the server to be used for other purposes, enter y.

Locating OS user account and home directory...

WARNING: If you remove the OS user account hadm you will have

to recreate it, the associated OS group account hadmg, and

the associated home directory /opt/JNPRhadm

This is neither necessary nor recommended if you are updating

an existing configuration.  Remove the OS user account? [n]:

Four-Server Strategy Only

10. You can now set up the server as the second SBR/management node in the new cluster. Because all preparatory steps have already been performed, follow the steps in Setting Up the Second SBR/Management Node in a Starter Kit101, with the exception of the last step for configuring the data nodes. After completing these steps, remember to return to this procedure to complete the remaining steps.

Four-Server Strategy Only

11. Start the second SBR/management node using this sequence of commands:

1. Log in to the SBR/management node as root.
2. Change directories to /opt/JNPRsbr/radius/.
3. Execute:
   ./sbrd start ssr
4. Execute:
   ./sbrd status
5. Examine each line and ensure the SSR process is running without error.

12. Create the database on the SBR/management (sm) node:

1. Log in as hadm.
2. Execute:
   ./CreateDB.sh

13. Start the RADIUS process on the SBR/management node:

1. Log in as root.
2. Change directories to /opt/JNPRsbr/radius/.
3. Execute:
   ./sbrd start radius
4. Execute:
   ./sbrd status
5. Examine each line and ensure the RADIUS process is running without error.

14. Now that the RADIUS process is running, you can complete the configuration using SBR Administrator. See Basic SBR Carrier Node Configuration. For complete details, see the Steel-Belted Radius Carrier 7.2 Administration and Configuration Guide.
