To ensure that your LifeKeeper configuration provides the protection and flexibility you require, you need to be aware of the configuration rules. To appropriately plan your configuration, you must understand your network configuration, interface selection, user system setup, hierarchy options and the IP configuration tasks. In addition to planning your configuration, this section also includes configuration examples and the specific tasks required to configure your recovery kit.

Configuring TCP/IP with LifeKeeper

This section contains information you should consider before you start to configure TCP/IP and examples of typical LifeKeeper IP configurations.

Please refer to the LifeKeeper for Linux Technical Documentation for instructions on configuring your LifeKeeper Core resource hierarchies.

Specific Configuration Considerations for TCP/IP

In order to properly configure your IP Recovery Kit, you should review the following topics to ensure that you have the information necessary to complete the configuration tasks:

See the following topics for further configuration considerations and examples:

LifeKeeper Configuration Tasks

The following configuration tasks for IP resources are described in this section, as they are unique to an IP resource instance and different for each recovery kit.

The following tasks are described in the Administration section within the LifeKeeper for Linux Technical Documentation because they are common tasks with steps that are identical across all Recovery Kits.

  • Create a Resource Dependency. Creates a parent/child dependency between an existing resource hierarchy and another resource instance and propagates the dependency changes to all applicable servers in the cluster.
  • Delete a Resource Dependency. Deletes a resource dependency and propagates the dependency changes to all applicable servers in the cluster.
  • In Service. Brings a resource hierarchy into service on a specific server.
  • Out of Service. Takes a resource hierarchy out of service on a specific server.
  • View / Edit Properties. View or edit the properties of a resource hierarchy on a specific server.

Note: Throughout the rest of this section, we explain how to configure your recovery kit by selecting certain tasks from the Edit menu of the LifeKeeper GUI. You can also select each configuration task from the toolbar. You may also right-click on a global resource in the Resource Hierarchy Tree (left-hand pane) of the status display window to display the same drop down menu choices as the Edit menu. This, of course, is only an option when a hierarchy already exists.

You can also right-click on a resource instance in the Resource Hierarchy Table (right-hand pane) of the status display window to perform all the configuration tasks, except Creating a Resource Hierarchy, depending on the state of the server and the particular resource.
