Tarik,
I believe that the "server network interface" only controls the Meta data
and that the back up data is controlled by "storage nodes".
With the NMO module (networker 6.1.3/4) the changes in scripts and util
files did not work - this was with a backup server that had 2 NIC's with
no route between them (not allowed to do routing on the servers).

update you RMAN script or you're SAP utl file to change the server name.
