What it says is this:

You have two media servers, server1 and server2.  
Server1 is the only one that will show up in your pull 
down menu, you will have to add server2 from the gui 
(xdevadm) or add it here KNOWN = server2.

HOWEVER:
If server2 is only a client, and not a NetBackup server 
at all, then it really shouldn't be here at all.

Did you have a second media server (slave server) 
before on server2?
