透過特定介面進行受管理檔案複寫

Summary: 在 DDOS 5.7 之前,只有備份和還原會使用 ifgroups。 本文件為因應措施。

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

受管理檔複製流量通過管理介面,而不是配置的 ifgroups。

管理介面將充滿複製流量,以限制使用此介面的存取。

Cause

DDBOOST 組態

Resolution

因應措施


如果 DNS 指向管理介面,請按照文檔中的後續步驟操作。

如果 DNS 指向特定介面 (即 10G 介面),請新增路由 (步驟 3)

若要驗證 DNS 設定,請執行下列步驟:

net show dns (verify that the DNS servers are correct)
net lookup <hostname>


1.創建一個本地主機條目,將主機名指向源和目標上的指定介面。

(注:路由語句的閘道必須是伺服器可以與之通信的閘道)。

-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.執行 "net host show" 以驗證更改是否已正確實施。

3.創建一個靜態路由,將主機名指向源和目標上的所需介面。

請參閱 Data Domain:新增靜態路由 ,以取得將路由新增至 DD 的特定資訊。以下範例適用於非 HA 和 DD OS 6.0 及更新版本。

-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.執行「route show table」 並驗證輸入內容是否正確

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.從備份應用程式

執行測試複寫工作 6.執行 iostat 5(或指定的秒數)並監控通過配置介面的流量:

iostat 2


11/10 15:48:35
