b. 在第三个网卡上配置与主备网卡无关网段地址,只要这两块网卡同网段即可,将其label加入/etc/hosts定义;
smitty chinet,选择en1,设置无关网段地址,例如两台分别为192.168.200.11和192.168.200.12;
Network Interface Name en1
INTERNET ADDRESS (dotted decimal) [192.168.200.11]
Network MASK (hexadecimal or dotted decimal) [255.255.255.0]
Current STATE up
编辑/etc/hosts文件,将两个新增地址分别对应一个IP Label如test1_heartbeat1;
192.168.200.11 test1_heartbeat1
192.168.200.12 test2_heartbeat1
c. Discover刷新集群内相关信息;
smitty cm_extended_config_menu_dmn快捷路径进入菜单,选择Discover HACMP-related Information from Configured Nodes让服务器自动刷新下cluster内相关信息(建议修改各种拓扑相关配置后都可以刷新);
d. HA network中建立第二个ether网络
smitty cm_config_hacmp_networks_menu_dmn快捷路径进入配置菜单,选择Add a Network to the HACMP Cluster,Discovered/,ether类型,这里只需要配置netmask与上述地址一致即可,不要求与第一个ether一致;
* Network Name [net_ether_02]
* Network Type ether
* Netmask [255.255.255.0] +
* Enable IP Address Takeover via IP Aliases [Yes] +
IP Address Offset for Heartbeating over IP Aliases [ ]
e. 修改第二个ether网络类型为private类型(可选);
smitty cm_config_hacmp_networks_menu_dmn快捷路径进入菜单,选择Change/Show a Network in the HACMP Cluster,选项新建的net_ether_02网络,修改如下
Network Name ethernet
New Network Name [ ]
* Network Type [ether] +
* Netmask [255.255.255.0] +
* Enable IP Address Takeover via IP Aliases [Yes] +
IP Address Offset for Heartbeating over IP Aliases [ ]
* Network attribute private
f. 添加第三个网卡到第二个ether网络;
smitty cm_config_hacmp_communication_interfaces_devices_menu_dmn快捷路径进入菜单,选择Add Communication Interfaces/Devices,Add Discovered Communication Interface and Devices,Communication Interfaces,选择新建的net_ether_02网络,F7(Esc+7)选择两块新加的网卡,Enter即可完成添加网卡。
