Terminating NDMP sessions
You can terminate an NDMP session if the session is not responding. The specified session stops processing its current requests and moves to an inactive state. This allows hung sessions to be cleared without the need for a reboot.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
In the navigation pane, click Configuration > System Tools > NDMP.
3.
Select the NDMP session that you want to terminate and click Terminate Session.
