The Sun Cluster module for Sun Management Center is used to monitor a Sun Cluster configuration. Perform the following tasks before you install the Sun Cluster module packages.
Space requirements - Ensure that 25 Mbytes of space is available on each cluster node for Sun Cluster–module packages.
The following are additional requirements for a Sun Cluster configuration:
Install the Sun Management Center agent package on each cluster node.
When you install Sun Management Center on an agent machine (cluster node), choose whether to use the default of 161 for the agent (SNMP) communication port or another number. This port number enables the server to communicate with this agent. Record the port number that you choose for reference later when you configure the cluster nodes for monitoring.
See your Sun Management Center installation documentation for information about choosing an SNMP port number.
Install the Sun Management Center server, help–server, and console packages on noncluster nodes.
If you have an administrative console or other dedicated machine, you can run the console process on the administrative console and the server process on a separate machine. This installation approach improves Sun Management Center performance.
Web browser - Ensure that the web browser that you use to connect to Sun Management Center is supported by Sun Management Center. Certain features, such as online help, might not be available on unsupported web browsers. See your Sun Management Center documentation for information about supported web browsers and any configuration requirements.
