When VCS does not know the status of a service group on a particular system, it autodisables the service group on that system. Autodisabling occurs under the following conditions:
When the VCS engine, HAD, is not running on the system.
Under these conditions, all service groups that include the system in their SystemList attribute are autodisabled. This does not apply to systems that are powered off.
When all resources within the service group are not probed on the system.
Recommended Action: Use the output of the command hagrp -display service_group to verify the value of the AutoDisabled attribute.
