preferred owner

preferred owner: The node on which you prefer each group to run. For example, the static load balancing model performs best when groups are appropriately balanced between two nodes. When a node fails, the remaining node takes over the groups from the failed node, but performance is diminished. By setting those groups to fail back to their preferred server (the failed node), you automatically restore maximum performance when failback occurs. A group does not fail back if a preferred owner is not selected.

You will not always choose a preferred owner because it may not matter where the group resides; all that matters is that the group is still running on one of the two nodes. Or, the nodes may be equally capable of handling the load required to use some or all of the resources.
