Symptoms

 在使用已配置的代理的情况下检索或刷新技术公告时 Unisphere 上出现警报。 
 警报文本:Failed to get technical advisory with configured proxy https://xxxxxxxxxxxxxx(无法在使用已配置的代理的情况下获得技术公告 https://xxxxxxxxxxxxxx)

故障处理:   
  • 在没有代理的情况下对 colu 服务器(负责检索技术公告的戴尔服务器)执行 Curl 命令。由于在没有代理服务器的情况下,不允许在用户环境之外进行通信,因此服务器超时。
curl -X POST https://colu.emc.v ; date

Closing connection 0
curl: (7) Failed to connect to colu.emc.com port 443: Connection timed out

  • 使用代理服务器对 colu 服务器执行 Curl 命令,返回“HTTP/1.1 400 Bad Request”。
curl -x http://< proxy_server_ip>:<port> -X POST https://colu.emc.com:443/soap/rpc -H “Content-Type: text/xml;charset=UTF-8” -H “ SOAPAction:”-v

Cause

在您可以将从 colu.emc.com 接收到的应用程序数据完全发送到 Unity 阵列之前,colu.emc.com 和代理服务器之间的连接已关闭。这似乎是由于 curl 处理连接的方式造成的。     

Resolution

此问题无法在新版本中重现。新版本将 curl 库升级到 7.63.0,而较旧版本仍使用 7.50.2。

升级到下一个版本应该可以解决这个问题。

临时解决办法:    
  • 请勿使用代理服务器。
  • 禁用或停用警报。
