Possible Changes to ClusterWare Configuration Files

A clean install of ClusterWare introduces various ClusterWare configuration files that include default settings that a local sysadmin may choose to modify. A subsequent upgrade from one ClusterWare release to a newer release will avoid replacing these potentially modified files. Instead, an update installs a new version of the default file as a file of the form CWconfigFile.rpmnew. Therefore, after a ClusterWare upgrade, the sysadmin is encouraged to compare each such existing CWconfigFile with the new default version to ascertain which of the new default entries are appropriate to manually merge into the preexisting CWconfigFile file.
