7 Using the Cockpit HA Cluster Management Web UI

In Oracle Linux 10, the web UI for creating and managing HA clusters is provided by the Cockpit HA Cluster Management add-on. The add-on replaces the pcsd web UI used in earlier releases of Oracle Linux.

The examples and procedures in this chapter assume you have completed the following prerequisites for nodes you plan to configure with the HA Cluster Management tool:

• Pacemaker and Corosync Configuration

  You need to complete the tasks described in Installing and Enabling the Pacemaker and Corosync Service for each node.

• pcs and hacluster Authentication

  For information about authentication and configuring hacluster credentials, see Step 1 of Creating the Cluster.

• This chapter also assumes that you have configured resolvable names for all the nodes.
