Solution

 
Run command :-tpautoconf -probe ndmp_host_name & tpautoconf -verify ndmp_host_name and found it enlists output successfully.
Telnet to 10000 port of the NDMP filer and it works fine.
 
Ran the following commands on the filer :
1)      nas_fs –list
2)      server_export   server_2
3)      nas_server -l –v
4)       server_export vdm0
5)      server_df server_2
