Configuring DNFS on VNX

Hi,

I am standing up a three-node Oracle RAC cluster on Sun/Oracle M4000 servers running Solaris 10. I am using NFS (VNX 7500) for shared storage and need to configure DNFS. Each RAC server has two 10GbE NIC ports that will be used for DNFS. Each NIC is on its own subnet as shown below from one server:

ixgbe0 10.9.100.20

ixgbe0 10.9.101.20

The NAS IP is 10.9.100.16.

The problem that I am running into is that traceroute from ixgbe0 to NAS runs fine where as it does not run fine from ixgbe1 to NAS. For example, the following runs fine:

traceroute -F -s 10.9.100.20 10.9.100.16 9000

Where as the following does not:

traceroute -F -s 10.9.101.20 10.9.100.16 9000

Is there anything that we need to configure on the NAS side so that traceroute can work?

Any help will be appreciated.

Thanks

Amir
