Before beginning the installation of VCS software, you can check the readiness of the systems where you plan to install VCS. The command to start the pre-installation check is:
installvcs -precheck system1 system2 ...
To check the systems
./installvcs -precheck north south
The program proceeds in a non-interactive mode, examining the systems for licenses, depots, disk space, and system-to-system communications.
