What needs to be copied from NodeA to NodeB after its installation in a cluster vault architecture?

In a cluster vault architecture, after installing NodeB, it is crucial to copy the additional keys and the Server ID from NodeA. This action is essential because the additional keys are part of the security framework that allows the cluster nodes to communicate securely and maintain the integrity of the stored data. The Server ID is equally significant; it ensures that NodeB is correctly identified within the cluster, which is vital for synchronization and redundancy purposes.

The additional keys and Server ID play a role in establishing trust and ensuring proper operation within the cluster, which enables high availability and load balancing of the vault services. By ensuring that NodeB has the same keys and identification as NodeA, the system can work seamlessly as a cohesive unit rather than as disparate entities. This synchronization is critical to maintaining the performance and security of the CyberArk environment.
