IP网络规划: IPAT via IP aliases(二)
设置 IPAT via IP aliases 功能 #smitty hacmp Extended Configuration > Extended Topology Configuration > Configure HACMP Networks > Change/Show a Network in the HACMP Cluster > Change/Show an IP-Based Network in the HACMP Cluster Change/Show an IP-Based Network in the HACMP Cluster Type or select values in entry fields. Press Enter AFTER making all desired changes. [Entry Fields] * Network Name net_ether_01 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 public +
简化了HACMP Cluster的配置与管理 通过磁盘传输心跳信号(Heartbeat over Disk) IPAT通过Alias实现(IPAT via Alias)(缺 省方式) 用户自定义的资源组(Custom RG) 快递磁盘接管(Fast Disk Takeover) HACMP-XD

– 至少2个 pseries 服务器作为cluster的节点(安装并运行 HACMP,每个节点的AIX 版本和HACMP的版本要完全一致) – 内置硬盘:预留一定的硬盘空间满足HACMP的安装要求, MIRROR – I/O插槽:要满足网卡、HBA卡(阵列和带库要分开)、串口 卡 – 至少一种non-IP 网络,通常采用RS232网络,如果某些节点 集成串口无法作心跳,要配#2943 8口异步卡,节点间要配 串口线 – 一个共享磁盘阵列(7133/FastT/ESS等)
