The problem is at Networker side not Oracle one.

The difference I see is:
send 'NSR_ENV=(NSR_SERVER=networker,NSR_CLIENT=rman)';
SEND DEVICE TYPE 'SBT_TAPE' 'NSR_ENV=(NSR_SERVER=networker,NSR_CLIENT=rman)';

This is the first part of the recovery information,and I have tried, or the same as the error

using target database control file instead of recovery catalog

allocated channel: t2
channel t2: SID=491 instance=test1 device type=SBT_TAPE
channel t2: NMDA Oracle v8.2.1

allocated channel: t3
channel t3: SID=588 instance=test1 device type=SBT_TAPE
channel t3: NMDA Oracle v8.2.1

Thank you for your reply, I think is the reason of networker. But I don't know much about it, then do not know what to do

Ask your Networker admin, here we are Oracle guys and so may not be able to answer to a Networker question or lead you to investigate in the proper way.

Oracle is only relaying the error that originated in the media manager. Oracle is the victim, not the culprit. You need to be looking into NetWorker.
