Figured out the issue. I forgot to load module on the server side.
Solution: Load module on all nodes involved in testing.

I am able to use the Lustre file system without any problem. I looked at /var/log/messages on the client and server node and there are no errors. Googling for the error, was not helpful. The script: lnet_selftest_wrapper.sh. has content which is mentioned on this page: http://wiki.lustre.org/LNET_Selftest (wrapper script at the end of the page). LFROM="10.0.3.4@tcp1" is the client node where I am running this script. LTO="10.0.3.6@tcp1" is one of the OSS server. I have total 3 of them.
