about the VCS behaviour on faulted resources

Hi Team,

Because ManageFaults is ALL by default, when the resource faults, VCS
calls Clean entry point. What is the task for Clean entry point for this
resource?  As far as I know, when VCS declares the resource as faulted,
depending on CRITICAL attribute for resource and AutoFailOver, VCS fail
sover the resource group. This resource group stays as faulted on the
first node. So, I need to clean fault manually to be able to make the
service group online on this node again. So,what the effect of "clean
entry point" if the reosurce faults?

If service group is faulted on both primary and secondary node, as far
as I know, it will not be failed-over. It stays as faulted on both node
until clearing it manually? Is there any way to automate the fail-over
while the service group are faulted on both node?

In fact I would like to understand the role of "clean entry point" for
resource when it faults bcause I am always clearing the resource's fault
manually? Is it there before declaring the resource is faulted? Please
explain me.
