## Prerequisites for Linux and AIX 

There are some prerequisites for installing SMUI to run on AIX and Linux. 

## Important: 

GLYPH<SM590000> Before using the SMUI, you must install and configure Secure Shell (SSH) on each node. 

GLYPH<SM590000> OpenSSL and OpenSSH must be installed on the system that is used as the SMUI server. 

GLYPH<SM590000> For some clusters utilities, it is necessary to have installed Python. 

## Supported web browsers 

SMUI is supported by the following web browsers: 

1. Google Chrome Version 57 or later 

2. Firefox Version 52 or later 

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). 

## 5.2.1 Planning and installation of SMUI for AIX 

## Planning 

The cluster nodes and SMUI server must be at one of the following AIX levels: 

GLYPH<SM590000> AIX Version 7.1 Service Pack 6 or later 

GLYPH<SM590000> AIX Version 7.2 Service Pack 1 or later 

## File sets to use with SMUI 

You must install the following file sets: 

cluster.es.smui.common This file set must be installed on SMUI clients and the server. 

cluster.es.smui.agent You must install the SMUI agent file set on all nodes that you want to manage with the SMUI. 

cluster.es.smui.server The GUI server file set is typically installed on only one system to manage clusters. 

## SMUI clients file sets 

You must install the following file sets on all nodes that you want to manage with the SMUI: 

GLYPH<SM590000> cluster.es.smui.agent 

GLYPH<SM590000> cluster.es.smui.common 

## SMUI server file sets 

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> cluster.es.smui.server 

GLYPH<SM590000> cluster.es.smui.common
