Cause

如果必须恢复 avagent 日志报告”No response to message或”CR_ERROR 在初始握手期间,存在一个通信问题,阻止了 send/acAvamar 网格与客户端之间的 k 条消息。

提醒:这两种情况下的所有错误都表明客户环境中存在与网络或防火墙相关的问题。

Resolution

以下步骤可用于帮助查找瓶颈:

1.检查所有必需的 Avamar 端口是否在防火墙中处于打开状态,并且可以发送和接收数据。
(Avamar 服务器到客户端以及客户端到 Avamar Server)

2.检查是否有任何防病毒或恶意软件检测软件阻止 Avamar 端口上的数据。

3.如果客户端位于 NAT 后面,请验证是否正确设置了路由表。

4.如果所有客户端上都出现相同的错误,请确保未对 Avamar 网络进行任何更改。

5.联系网络团队,跟踪从故障客户端到 Avamar 网格的网络流量,并检查网络中的数据包丢弃。

6.如果找不到问题,请收集 tcpdumpWireshark Netmon 信息并 创建服务请求。
