Symptoms
托管文件复制流量通过管理接口,而不是配置的接口组。
管理接口将被复制流量淹没,限制使用接口的访问。

Cause

Resolution
解决方法
如果 DNS 指向管理接口,请按照文档中的后续步骤操作。
如果 DNS 指向特定接口(即 10G 接口),请添加路由(步骤 3)
要验证 DNS 设置,请执行以下操作:
net show dns (verify that the DNS servers are correct)
net lookup <hostname>
1.创建一个本地主机条目,将主机名指向源和目标上的指定接口。
(注意:路由语句的网关必须是服务器可以与之通信的网关。
-源-
net hosts add <Destination IP> <Destination FQDN> <Destination shortname>
Example:
net hosts add 192.168.1.150 dest.emc.com dest
-目的地-
net hosts add <Source IP> <Source FQDN> <Source shortname>
Example:
net hosts add 10.10.5.150 source.emc.com source
2.在USB端口上运行一个 "net host show" 验证更改是否已正确实施。
3.创建将主机名指向源和目标上所需接口的静态路由。
请参阅 Data Domain:添加静态路由 ,了解有关将路由添加到 DD 的特定信息。以下示例适用于非 HA 和 DD OS 6.0 及更高版本。
-源-
route add -host <destination IP> gw <specified gateway> <desired source interface>
Example:
route add host 192.168.1.150 gw 10.10.5.1 dev eth0a
-目的地-
route add -host <source IP> gw <specified gateway> <desired destination interface>
Example:
route add host 10.10.5.150 gw 192.168.1.1 dev eth0b
4.运行“route show table”并验证条目是否正确。
Example:
route show table
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.150 10.10.5.1 255.255.255.0 U 0 0 0 eth0a
route show table
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.5.150 192.168.1.1 255.255.255.0 U 0 0 0 eth0b
5.从备份应用程序
运行测试复制作业 6.运行 iostat 5(或指定的秒数)并监视通过配置的接口的流量:
IOSTAT2
11/10 15:48:35

7.如果指定接口的流量增加,则已实施解决方法。
8.如果流量仍通过管理接口,请查看系统上的设置或联系 Data Domain 网络专家。
