When I/O services from the control domain and alternate I/O domainfail, VCS fails over the LDom from one system to another system. LDom continuesto be functional on the same system and does not need a fail over if one of the I/Odomain continues to provide service.VCS uses service groups and resources to manage the storage and network servicesthat are provided to a Logical Domain. These service groups are monitored by theAlternateIO resource. The AlternateIO service group provides the informationabout the state of the storage and network services to the LDom agent. VCS failsover the Logical Domain when services from both the I/O domains fail.Perform the following tasks to configure VCS to manage a Logical Domain:■Identify supported storage and network servicesSee Identify supported storage and network services
