Understanding Cluster Network Requirements and Heartbeating

To avoid a single point of failure, the cluster should have more than one network configured. Often the cluster has both IP and non-IP based networks, which allows HACMP to use different heartbeat paths. Use the Add a Network to the HACMP Cluster WebSMIT panel to configure HACMP IP and point-to-point networks.

You can use any or all of these methods for heartbeat paths:
•Point-to-point networks
•IP-based networks, including heartbeating using IP aliases.
Launching the WebSMIT Interface
Use WebSMIT to:
•Navigate the running cluster.
•View and customize graphical displays of networks, nodes and resource group dependencies.
•View the status of any connected node (with HACMP cluster services running on the nodes).
Starting WebSMIT
For instructions on integrating WebSMIT with your Apache server, and for launching WebSMIT, see the /usr/es/sbin/cluster/wsm/README readme file. It contains sample post-install scripts with variables. Each variable is commented with an explanation of its purpose along with the possible values. You can modify the values of the variables to influence the script behavior.
To start WebSMIT:
1.Using a web browser, navigate to the secure URL of your cluster node, for instance enter the URL similar to the following:
https://..com:42267
The 42267 is the name of the port for HACMP for Linux. The entry is optional, it is only necessary if you are logging in to a server that is not part of your local network. The system asks you to log in.
2.Log in to the system and press Continue. WebSMIT starts.
