Hello Pradeep,
If you had mentioned from the outset that your problem was due to replication it really would have helped.
So, reason aside, you find yourself running on the secondary node and I will assume that you have resolved whatever problem there was on the primary node and now you want to be running on the primary node again. Is that a fair summary ?
On both your primary and secondary sites please run the following command and post the output for each site in the thread. Also post (or upload) your nameserver.ini file.
hdbnsutil -sr_state
What steps/process did you follow so that you are running on the secondary site ?
If you provide a good summary of what happened and what steps you took up until now it really will help anyone who wants to help you.
KR,
Amerjit
