Cause

Hay un problema de certificado par entre el cliente de NetWorker y el nodo de almacenamiento de NetWorker.

Resolution

Borre la "información del par NSR" para el cliente y el nodo de almacenamiento de NetWorker en ambos hosts.

En el cliente de NetWorker: 
nsradmin -p nsrexeced
print type: nsr peer information; name: STORAGE_NODE_NAME
delete
yes
quit
Ejemplo: 
[root@lnx-srvr01 ~]# nsradmin -p nsrexecd
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> p type: nsr peer information; name: storage.networker.lan

NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> quit

quit
Ejemplo: 
[root@storage ~]# nsradmin -p nsrexecd
