Methods for virtual IP addresses to move among OceanStor 9000 network ports

OceanStor 9000 provides virtual IP addresses (also called floating IP addresses) for failovers in NFS sharing scenarios. A floating IP address is allocated to each front-end service port of a node. If this node is faulty, the floating IP address automatically moves to the front-end port of a normal node. After the fault is rectified, the previous floating IP address preferentially moves back to the rectified node. If the previous floating IP address has been occupied, an idle IP address is allocated from the dynamic IP address pool to the rectified node.
A dynamic IP address is a floating IP address which moves away from a faulty node based on the load balancing policy.
