4.0 Configuring and Managing Cluster Resources

Cluster resources must be created for every resource or application you run on servers in your cluster. Cluster resources can include Web sites, e-mail servers, databases, file systems, virtual machines, and any other server-based applications or services you want to make available to users at all times.

You can either use the graphical HA Management Client utility, or the cibadmin command line utility to create resources.

This chapter introduces the graphical HA Management Client and then covers several topics you need when configuring a cluster: creating resources, configuring constraints, specifying failover nodes and failback nodes, configuring resource monitoring, starting or removing resources, configuring resource groups or clone resources, and migrating resources manually.
