SA Interview and the Core Definition File (CDF)

During installation, you are required to provide values for certain SA parameters used to configure your SA installation. This process is known as the SA Interview. The values you provide are saved to a Core Definition File (CDF).

SA creates the first CDF when you install the SA Primary Core. You will use this CDF later to add a Secondary Core for a Multimaster Mesh (multiple core SA installation) or perform an upgrade. See Reusing a Core Definition File (CDF). The CDF is saved in:

/var/opt/opsware/install_opsware/cdf/cdf_<timestamp>.xml

In some cases, when you provide a parameter value, the SA Installer validates the response (for example, a directory or path that does not exist or an invalid value or range); you are asked to re-enter a value if the installer is not able to validate your response. Some parameters are also revalidated during the actual installation of the Core Components. If a response to a prompt cannot be validated at time of installation, the installer runs a mini-interview during which you can provide a valid response.
