Optional. A root user within a Solaris environment can choose to give root privileges within the cluster to the cluster administrator.
By default, only root can start, stop, or restart the cluster.
Give root privileges to the cluster administrator so that it can start a local host in the cluster, or shut down or restart any hosts in the cluster from the local host. For the cluster administrator or root to start the cluster, or start any hosts specified by name, you need to be able to run rsh across all hosts in the cluster without having to enter a password; see your operating system documentation for information about configuring rsh.
Do the following to give root privileges to the cluster administrator for one host. Run the command as root on each host in the cluster.
