We are running 2 node cluster and Node 1 is primary and Node 2 is secondary. If I set the AutoStartList = { Node1 }
IF I reboot Node1, SG will fail over to Node2, but when Node 1 comes back online, would SG will fail over back to Node1 since I set AutoStartList =( Node1} ?
If node 1 or node 2 dies, if service group is running on that node then VCS will fail service group to other node, regardless of AutoStartList
If you set AutoStartList to only 1 node, then if the service group is offline (like when both cluster nodes have been rebooted), then the service group will ONLY start on the node that is in AutoStartList, so if ONLY the other node (one not in the AutoStartList) comes up, then you will need to manually online the service group
As Kevin, says, VCS will not switch a service group from a healthy system as this creates an outage for the service group
Stopping and moving a service is considered to be an unusual event that should not be done automatically (unless there is a failure of some-sort); VCS is all about "High Availability", and taking a service offline to move it to another node incurs an amount of service outage -- this is something VCS tries very hard to avoid. It is up to the System Administrator to decide when it is appropriate to take the service down and move it over to the "preferred" node.
