With ethernet and a linux server, I can set up up aliases (virtual IP addresses) and assign multiple IPs to a single NIC. Can this be done with an HCA and IPoIB? For example, could I configure ib0:1 to be 192.168.0.1/24 and ib0:2 to be 10.0.0.1/24? I have tried this on a RHEL5 box and it doesn't seem to want to accept it, but I don't know if there is another piece somewhere that I need to configure.
