The real address of your OSAs has nothing to do with the virtual address used in the CP directory definition. They don't have to match at all.
On the installation server, the starter system NICDEF is where we preconfigured it, and the configuration files inside the system all expect a virtual NIC at that address. Just attach the real device to virtual address 340, or better yet, use a VSWITCH and then you don't care at all what the physical address is. On servers you install from the starter system, you can use any virtual address you want. You still should use the VSWITCH, but the resulting server doesn't care.
