Detached Network Adapters

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 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 and the NIC is unplumbed.

With the IP Network Multipathing reboot-safe feature, the static IP addresses in the /etc/hostname.* file that are associated with the missing card are hosted automatically on an alternate interface within the same IP Network Multipathing group. However, these addresses are returned to the original interface automatically if the original interface is inserted back into the system at a later time.
