Yes >From the Open Systems Adapter-Express Customers Guide and Reference: <quote> ARP Takeover ... When TCP/IP is started in QDIO mode, it downloads all the home IP addresses in the stack and stores them in each OSA-Express feature. This service of QDIO architecture occurs automatically for OSD channels. For OSA-Express features set up as OSE channels (non-QDIO), you must define multiple IP addresses in the OAT using OSA/SF as all the ARP functions reside in the Host TCP/IP Stack. The OSA-Express then responds to ARP requests for its own IP address, as well as for virtual IP addresses (VIPAs). The OSA that is planned to takeover the ARP responsibility should have its own IP address, VIPA address and the IP addresses that it is planned to takeover in its OSA Address Table. ... </quote> >2.
