バックアップに使用されるデバイスは、スタンドアロンのNetWorkerストレージ ノードを介して構成されます。デバイスがNetWorkerサーバーの組み込みストレージ ノードを使用していない。

NetWorkerストレージ ノードのdaemon.rawは、同じクライアントのピア不整合の問題を報告します。

Príčina

NetWorkerクライアントとNetWorkerストレージ ノードの間にピア証明書の問題があります。

Riešenie

両方のホスト上のNetWorkerストレージ ノードとクライアントの「NSRピア情報」をクリアします。

NetWorkerクライアントで、次の手順を実行します。 
nsradmin -p nsrexeced
print type: nsr peer information; name: STORAGE_NODE_NAME
delete
yes
quit
Example: 
[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
                        type: NSR peer information;
               administrator: root,
                              "user=nsrnmc,host=lnx-srvr01.networker.lan",
                              "user=root,host=lnx-srvr01.networker.lan";
                        name: storage.networker.lan;
               peer hostname: storage.networker.lan;
          Change certificate: ;
    certificate file to load: ;
nsradmin> d
                        type: NSR peer information;
               administrator: root,
                              "user=nsrnmc,host=lnx-srvr01.networker.lan",
                              "user=root,host=lnx-srvr01.networker.lan";
                        name: storage.networker.lan;
               peer hostname: storage.networker.lan;
          Change certificate: ;
    certificate file to load: ;
Delete? y
deleted resource id 1.0.4.4.48.4.0.0.187.151.35.103.192.168.0.6(1)
nsradmin> q
[root@lnx-srvr01 ~]#
NetWorkerクライアントがストレージ ノード上のnsrexecdプロセスに到達できることを確認します。 
nsradmin -p nsrexecd -s STORAGE_NODE_NAME
Example: 
[root@lnx-srvr01 ~]# nsradmin -p nsrexecd -s storage.networker.lan
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> quit
[root@lnx-srvr01 ~]#

NetWorkerストレージ ノードで、次の手順を実行します。 
nsradmin -p nsrexeced
print type: nsr peer information; name: NETWORKER_CLIENT_NAME
delete
yes
quit
Example: 
[root@storage ~]# nsradmin -p nsrexecd
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> p type: nsr peer information; name: lnx-srvr01.networker.lan
                        type: NSR peer information;
               administrator: root, "user=nsrnmc,host=storage.networker.lan",
                              "user=root,host=storage.networker.lan";
                        name: lnx-srvr01.networker.lan;
               peer hostname: lnx-srvr01.networker.lan;
          Change certificate: ;
    certificate file to load: ;
nsradmin> d
                        type: NSR peer information;
               administrator: root, "user=nsrnmc,host=storage.networker.lan",
                              "user=root,host=storage.networker.lan";
                        name: lnx-srvr01.networker.lan;
               peer hostname: lnx-srvr01.networker.lan;
          Change certificate: ;

nsradmin> q
[root@storage ~]#
NetWorkerストレージ ノードがクライアント上のnsrexecdプロセスに到達できることを確認します。 
nsradmin -p nsrexecd -s NETWORKER_CLIENT_NAME
Example: 
[root@storage ~]# nsradmin -p nsrexecd -s lnx-srvr01.networker.lan
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> quit
