Dynamic Reconfiguration (DR) uses IP network multipathing to decommission a specific network device without impacting existing IP users. Before a NIC is DR-detached, off lined, all failover IP addresses are failed over. These addresses, that are hosted on that NIC, are automatically failed over to another NIC in the same IP network multipathing group. The test addresses are brought down. Then, the NIC is unplumbed.
With the IP network multipathing reboot-safe feature, the static IP addresses are hosted automatically on an alternate interface. The interface must be within the same IP network multipathing group. The static IP addresses are the addresses in the /etc/hostname.* file that are associated with the missing card. However, these addresses are returned to the original interface automatically when the original interface is inserted back into the system at a later time.
