New servers need to be configured when extending Oracle Exadata Elastic Configurations.

The new servers do not have any configuration information, and you cannot use Oracle Enterprise Manager Cloud Control to configure them. The servers are configured using the Oracle Exadata Deployment Assistant (OEDA) or manually.

• Configuring Servers Using OEDA
  When adding servers to an Oracle Exadata, you can use OEDA.
• Configuring New Servers Manually
  When adding servers to an Oracle Exadata, you can configure the servers manually instead of using OEDA.
