Installing VCS with a response file where ssh or rsh
are disabled
In secure enterprise environments, ssh or rsh communication is not allowed
between systems. In such cases, the installvcs program can install and configure
VCS only on systems with which it can communicate—most often the local system
only. When installation is complete, VCS creates a response file.
See “Response file variable definitions” on page 166.
The response file that the installvcs program generates contains descriptions and
explanations of the variables and their values. You copy this file to the other
systems in the cluster, and edit it to reflect the current local system. You can use
the installation program with the -responsefile option to install and configure
VCS identically on each system without being prompted.
