metalink note 283107.1介绍了如何设置VIP的IPMP，此处记录一下设置过程。

o Existing 10g RAC installation

   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

      For existing 10g RAC installations, use srvctl to modify the VIP to use all the NIC's

      within the same IPMP group.  The following example is configuring the VIP for jphp1580,

      to use the two NIC's specified in the command line.

        # srvctl stop nodeapps -n jpsun1580

        # srvctl modify nodeapps -n jpsun1580 -o /u01/app/oracle/product/10gdb -A 146.56.78.1/255.255.252.0/ce0\|ce1

        # srvctl start nodeapps -n jpsun1580

10.99.32.11被加到了bnx1上。

在修改过程中并未停止数据库，因此此操作应该是可以在线做。不过在操作过程中listener和VIP会被停掉，这一点需要注意。
