    The Oracle grid requirements for 11g, R2 (briefly!) are this, but be aware that there are meny additional details too:

    Each node must have at least two network adapters: one for the public network interface and
    the other for the private network interface or interconnect.

    In addition, the interface names associated with the network adapters for each network must be the same on all nodes.

    For example, in a two-node cluster, you cannot configure network adapters on node1 with eth0 as
    the public interface, but on node2 have eth1 as the public interface.

    Public interface names must be the same, so you must configure eth0 as public on both nodes.

    You should configure the private interfaces on the same network adapters as well. If eth1 is the private interface for
    node1, then eth1 should be the private interface for node2.
    Before starting the installation, on each node, you must have at least two interfaces to
    configure for the public and private IP addresses.

    Ur information helped me a lot, because i figured out the issue there are different subnets in the two nodes, and i told my network team to set it up.he is working now.
