With the help of ShaoLin HA Cluster's system image oriented clustering, administrators need not to specialize the configuration of applications. However, if you are going to make changes while the clusters are on-line, you do have something to aware of. This chapter give examples on some example procedures on some administrative task of ShaoLin HA Cluster.

The most safe way to setup and configure a cluster is to power-off the standby cluster and then make changes at the active cluster. After making the changes, rerun the ShaoLin HA Cluster Webmin configuration wizard to regenerate the cluster boot images. Test the new configuration with a test mode, then reboot the standby cluster into a production standby cluster.
