VCS provides a method to determine where a service group comes online when the cluster starts. Setting the AutoStartPolicy to Load instructs the VCS engine, HAD, to determine the best system on which to start the groups. VCS places service groups in an AutoStart queue for load-based startup as soon as the groups probe all running systems. VCS creates a subset of systems that meet all prerequisites and then chooses the system with the highest AvailableCapacity.
Set AutoStartPolicy = Load and configure the SystemZones attribute to establish a list of preferred systems on which to initially run a group.
