Installation Requirements for Sun Cluster Monitoring

The Sun Cluster module for Sun Management Center (formerly Sun Enterprise SyMON) is used to configure resource groups and monitor clusters. 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.

• Sun Management Center packages - You must install the Sun Management Center server, help server, and console packages on non-cluster nodes. If you have an administrative console or other dedicated machine, you can realize improved performance if you run the console on the administrative console and the server on a separate machine. You must install the Sun Management Center agent package on each cluster node.

  Follow procedures in the Sun Management Center documentation to install the Sun Management Center packages.

• Simple Network Management Protocol (SNMP) port - When you install Sun Management Center on the agent, 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 you choose for reference later when you configure the cluster for monitoring.
