Resolving NSR peer information errors

While running a backup you may see in the savegroup completion report.

nsrexecd: SYSTEM error: There is already a machine using the name: "hosta". Either choose a different name for your machine, or delete the "NSR peer information" entry for "hosta" on host: "hostb"

You may also see the above after the NetWorker client upgraded with the same host name which created a duplicate NSR peer information for the client.

These errors are seen in the savegroup completion report, in the daemon log file, and occasionally when configuring a new NetWorker client:

  • nsrexecd SYSTEM error: There is already a machine using the name: "schlumpf". Either choose a different name for your machine, or delete the "NSR peer information" entry for "schlumpf" on host: "smurf"
  • Authentication warning: Conflicting NSR peer information resources detected for host 'schlumpf'. Please see server log for more information.
  • Security certificate used to sign this software does not match your known certificates

The quickest way to resolve this

  • Delete the NSR Peer Information of the NetWorker Server on the client/storage node,
  • Then delete the NSR Peer Information for the client/storage node from the NetWorker Server.

Using the following steps to delete the NSR peer information on NetWorker Server and on the Client.

  1. At NetWorker server command line, go to the location /nsr/res
  2. Type the command:
    nsradmin -p nsrexec
    print type:nsr peer information; name:client_name
    delete
    y

Specify the name of the client/storage node in the place of client_name.

  1. At the client/storage node command line, go to the location /nsr/res
  2. Type the command:
    nsradmin -p nsrexec
    print type:nsr peer information
    delete
    y
