I have solutioned this question,Answer is ......

When the system boots, the NFS server is not enabled unless there are NFS exports listed in /etc/dfs/dfstab.

To start the nfs server after adding an entry to dfstab, issue
the following command:


# /etc/init.d/nfs.server start



Note that it isn't currently possible to start the nfs server
using the "nfs.server" script unless there are entries in
/etc/dfs/dfstab.


If you want to do automatic sharing of CDs through vold, you need
to export at least one other filesystem if you're running Solaris 2.6
or earlier.


Thnx everyone
