The fai l o verd o mai ns section contains a fail o verd o mai n section for each failover domain

in the cluster. This example has one failover domain. In the fail o verd o mai n line, the name

(name) is specified as exampl e_pri. In addition, it specifies no failback (fai l back= "0 "), that

failover is ordered (o rd ered = "1"), and that the failover domain is unrestricted

(restri cted = "0 ").

7.5. Configuring HA Services

Configuring HA (High Availability) services consists of configuring resources and assigning them to

services.

The following sections describe how to edit /etc/cl uster/cl uster.co nf to add resources and

services.

Section 7.5.1, “ Adding Cluster Resources”

Section 7.5.2, “ Adding a Cluster Service to the Cluster”

Important

There can be a wide range of configurations possible with High Availability resources and

services. For a better understanding about resource parameters and resource behavior, refer

to Appendix B, HA Resource Parameters and Appendix C, HA Resource Behavior. For optimal

performance and to ensure that your configuration can be supported, contact an authorized

Red Hat support representative.
