Hi Jayanthi,
If you can see the instance running, the Delphix V2P job has completed, and you can connect in using sqlplus (or similar), then it was successful.
Adding it back into Delphix is not really needed here, but if you really wanted to, you could do that by adding the environment/host in Delphix, which should find the DB during the discovery phase.
If the server that you have exported to using V2P is already defined in Delphix (i.e. an existing remote host), then refreshing the environment in the GUI should re-run Discovery and find the physcial DB as well.
Best Regards,
Scott.
