allocate channel t1 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=bcksrv, NSR_CLIENT=server1, NSR_DATA_VOLUME_POOL=DAILYPOOL, NS
R_DEBUG_FILE=/home/oracle/RMAN/debug1.log)';

I found the following error in the debug file:

SBT-8233 08/03/10 22:22:50 lnm_index_cfx_pconn: The NW authentication for client 'server1' was refused by server 'bcksrv' be

Adding server2 to the server1's remote access list solved the problem. On NetWorker Administration interface, first choose "Configuration" tab, click "Clients", right-click "server1" and choose properties. Selects "Globals" tab and add the following line to "Remote access" box:
oracle@server2
