Warning:  It is recommended that the PowerHA GUI binary files match with the same  version of PowerHA SystemMirror. If the GUI is an earlier version, the administrator can  potentially experience problems when managing the cluster through the GUI (usually  communication problems). SMUI is supported by the following web browsers: The cluster nodes and SMUI server must be at one of the following AIX levels: You must install the following file sets: You must install the following file sets on all nodes that you want to manage with the SMUI: The GUI server file set is typically installed on only one system to manage clusters. The  cluster.es.smui.common  file set must be installed on both SMUI clients and the server. GLYPH<SM590000> Before using the SMUI, you must install and configure Secure Shell (SSH) on each  node.
