Capturing Your Current Cluster Configuration

To prepare for the upgrade, capture your current cluster configuration:

1. (Optional) If you previously upgraded the D nodes in your cluster to Release 8.3.0 by pushing the package only as described in Step 3 of Preparation, you need to copy the sbrd script from one SM node to each data node. If you upgraded using the pkgadd command, you do not need to perform this step.
2. Log in to each node in your cluster as root, and verify that it is operating correctly. Print out the status of each node in the cluster. For example:

   Execute:
   root@uranus-js: /opt/JNPRsbr/radius./sbrd status
