Symptoms

升级到 NetWorker 9.1 才能使用 vSphere 6.5。

 

NMC 中出现以下错误消息：

Unable to connect server, Remote system error, No connection could be made because the target machine actively refused it


nsrctld NSR notice Daemon nsrd terminated


C:\Program Files\EMC NetWorker\nsr\logs>nsrrpcinfo -t <Networker_server_name> 390103
nsrrpcinfo: Remote system error - Only one usage of each socket address (protocol/network address/port) is normally permitted.


nsrjobd severe Unable to query RAP database for initial RDZ value: RPC send operation failed; peer = ::1:[8992], errno = An existing connection was forcibly closed by the remote host.

 

Cause

进程 nsrd 不断失败并重新启动。
NSRDB 已损坏。

 

Resolution

步骤：

  1. 按照步骤进行恢复 nsrdb用 nsrdr。
    以管理员用户或 root 用户身份打开命令提示符并运行：
    mminfo -B

  2. 如果 MM 不可用，请登录 \nsr\logs\policy\Server Protection\Server backup，搜索最新的引导数据库备份，并记下突出显示的信息。
    例：

129292:save: Successfully established Client direct save session for save-set ID '2025432100' (networker.com:bootstrap) with Data Domain volume 'POOLFILESERVER.001'.
Picked up JAVA_TOOL_OPTIONS: -Djava.vendor="New Oracle"
save: bootstrap                   level=full,     36 MB 00:00:23    412 files
completed savetime=1488561188
7167:save: save completion time: 3/3/2017 11:13:31 AM
94694:save: The backup of save set 'bootstrap' succeeded
Bootstrap saveset: 2025432100
Volume:POOLFILESERVER.001

 

  1. 里面 nsr\logs\policy\Server Protection\Server backup，您还可以找到包含有关池或卷的信息的文件。例如，

3/3/2017 11:13:08 AM  2025432100  POOLFILESERVER.001 datadomain datadomain_FILESERVER datadomain:/ddnw/FILESERVER

 

  1. 停止所有 NetWorker 服务。

    重命名 res 文件夹，位于 <NetWorker Installation path>\nsr

  2. 启动 NetWorker 服务。

  3. 打开 NMC，重新配置保存存储集的设备。

  4. 在命令提示符下，以管理员用户或 root 用户身份运行以下命令：

nsrdr -B {bootstrap_saveset_id} -d {device}

 

  1. 以交互模式打开 nsrdr。例如，
    nsrdr -B 2025432100 -d ddnw

  1. 完成后，重新启动所有 NetWorker 服务。

 

如果 NMC 为空或显示错误消息，请打开 NMC：

An error occurred while validating user credentials. Verify that NetWorker Authentication Service is running.

 

  1. 停止商品及服务税服务。

  2. 使用 NWS 重新授权 NMC。

gstauthcfg -ct -h New_authentication_service_hostname -p port_number
nsrauthtrust -H Authentication_service_host -P Authentication_service_port_number
nsraddadmin -H Authentication_service_host -P Authentication_service_port_number
