Users logged with administrative or root privileges are granted privileges that exceed those of cluster administrator, such as the ability to start and stop a cluster.

If you do not have root privileges and the external communication port for VCS is not open, you cannot run CLI commands. If the port is open, VCS prompts for your VCS user name and password when you run haxxx commands.

You can use the halogin command to save the authentication information so that you do not have to enter your credentials every time you run a VCS command.
