vProxy 备份失败，并显示错误：ddp_connect_with_config（） 失败，主机名：DD_name，错误：5075-DDBOOST Error 1 for lookup /backup/ost on DD_Name

ddp_connect_with_config() failed, Hostname: DD_name, Err: 5075-DDBOOST Error 1 for lookup /backup/ost on DD_Name (nfs: Operation not permitted)

初始检查：

• DDBoost 在 DD 上运行
• 在 Data Domain 上启用了 NFSv3
• 防火墙端口在 DD 和 vProxy 之间打开：NVP vProxy：对备份和还原操作的网络连接进行故障处理
• 使用的 DDBoost 密码正确无误
• DDBoost 客户端配置允许以下特定客户端：

• 1) Example:  
  
  Below example shows both "*" and a client name.  If "*" is missing then only clients in the list are permitted to connect to the DD.
  
  # ddboost clients show config
  Client               Encryption Strength   Authentication Mode
  ------------------- -------------------   -------------------
  *                    none                  none
  MyClient.mycomp.com  none                  none
  MyOtherClient        none                  none
  -------------------  -------------------   -------------------
  (**) The global security settings take precedence over these client(s) specific settings.
  
  2) Example from ddfs.info:
  07/03 14:59:25.659490 [7ff122a44170] WARNING: Client <MyOtherClient.mycomp.com> did not match access list entries
  07/03 14:59:25.659521 [7ff122a44170] nfsproc3_ost_mnt_3_svc: client access denied for <Client IP> version 7.0
  
  3) In some cases you will see that the error log lists the FQDN or the short name, but the client config is using the other form of the name. The configuration and the client name must match exactly. The DDBoost Plugin on the client will determine the name for the client. This will check the local hosts file on the client for a match for the source side IP for the client. If there is a match, it will use it. (Selecting the FQDN name if one is available, then short name) If there is no match, then the plugin will do a DNS query for the IP and use the response returned.
  
  4) If there is a discrepancy between the clients local host entry verses the DDBoost client config, ask the customer to choose which configuration that they would like to change.
  
  a) add "*" to the DD clients list will allow any client with proper credentials to authenticate to the DD.
  # ddboost clients add *
  
  b) add the corresponding name (from the error log, or client side local hosts file) to the DD:
  # ddboost clients add <hostname>
  
  c) modify the local hosts file or DNS for the IP address being used by the client to make it reflect the client name that was added to DD clients list.
  Example for Linux:
  file: /etc/hosts
  10.11.12.13 MyOtherClient.mycomp.com MyOtherClient
    changed to 
  10.11.12.13 MyOtherClient
  
  
  
  

如果以上所有内容均得到确认，请检查用于 vProxy 的 MTREE 的 DDBoost 密码长度。允许用于 vProxy 的最大密码长度为 30 个字符。

如果密码长度不是很大，建议使用“ddpconnchk”实用程序检查 vProxy 和 DD 之间的连接性。有关使用“的更多详细信息”ddpconnchk': NetWorker：如何使用 DDPCONNCHK 工具测试来自 NetWorker 主机的 DD ddboost 连接
