Setting up ssh or rsh for inter-system communications
The installer uses passwordless Secure Shell (ssh) or Remote Shell (rsh) communications among systems. During an installation, you choose the communication method that you want to use. Or, you can run the installer -comsetup command to set up ssh or rsh explicitly. When the installation process completes, the installer asks you if you want to remove the password-less connection. If installation terminated abruptly, use the installation script's -comcleanup option to remove the ssh or rsh configuration from the systems.
In most installation, configuration, upgrade (where necessary), and uninstallation scenarios, the installer configures ssh or rsh on the target systems. When you perform installation using a response file, you need to set up ssh or rsh manually, or use theinstaller -comsetup option to set up an ssh or rsh configuration from the systems.
