1 规划

项目 硬件 支持 要求 PowerHA Hardware Support Matrix： http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/TD105638 系统版6100-06 or 7100 本要求 补丁版本推荐 http://www14.software.ibm.com/webapp/set2/flrt/home 软件 要求 The following Base Operating System (BOS) components for AIX are required for PowerHA: bos.adt.lib bos.adt.libm bos.adt.syscalls bos.ahafs bos.clvm.enh bos.cluster bos.data bos.net.tcp.client bos.net.tcp.server bos.rte.SRC bos.rte.libc bos.rte.libcfg bos.rte.libcur

bos.rte.libpthreads bos.rte.lvm bos.rte.odm cas.agent (required for the IBM Systems Director plug-in) The following file sets on the AIX base media are required: rsct.basic.rte rsct.compat.basic.hacmp rsct.compat.clients.hacmp The appropriate versions of RSCT for the supported AIX releases are also supplied with the PowerHA installation media. 硬件 要求 Have at least two network adapters connected to different Ethernet switches in the same virtual LAN (VLAN) Employ dual-fabric SAN connections to the storage subsystems using at least two Fibre Channel (FC) adapters and appropriate multipath drivers. 网络 要求 共享 存储 支持主流SAN存储 PowerHA 7.1 supports only the use of enhanced concurrent volume groups 3个网段，不再支持IP替换的方式

SAN 心跳 repository disk 资料 交换机上面要划zone,HBA卡要设置(查看2.2) 存储上的磁盘，大小512M≤460G。不支持LVM镜像。 7.1.1后支持第三方多路径 POWREHA 信息中心：http://publib.boulder.ibm.com/infocenter/aix/v7r1/index.jsp?topic=/com.ibm.aix.powerha.navigation/powerha_pdf.htm 相关资源下载（powerha资源汇总）： http://www-03.ibm.com/systems/power/software/availability/aix/resources.html 红皮书： IBM PowerHA SystemMirror 7.1 for AIX.pdf IBM PowerHA SystemMirror Standard Edition 7.1.1 for AIX Update.pdf

2 安装软件

2.1 拓扑图

2.2 SAN 设置（可选）

? zoneing:

两个SAN交换机上分别创建主机到主机的zone。 ? 修改HBA卡属性：

? 方法一：适用于可以删除子设备时

rmdev -Rl fcsX chdev -l fcsX -a tme=yes chdev -l fscsiX -a dyntrk=yes -a fc_err_recov=fast_fail cfgmgr -l fcsX;cfgmgr -l sfwcommX 验证： lsdev -C | grep -e fcsX -e sfwcommX lsattr -El fcsX | grep tme lsattr -El fscsiX | grep -e dyntrk -e fc_err_recov 方法二：适用于设备忙时，重启生效

chdev -P -l fcsX -a tme=yes

chdev -P -l fscsiX -a dyntrk=yes -a fc_err_recov=fast_fail 2.3 安装软件

最简安装包（待测试）

cluster.es.client cluster.es.server cluster.es.cspoc 3 设置网络相关

3.1 网卡IP设置

IP 标签地址 Syndey_en0 Syndey Perth_en0 Perth_en1 Perth Perth_svc 网络接口 网络名 en0 en0 en1 接口功能 IP 地址 100.10.1.10 网络掩码 255.255.255.0 ether1 #boot1 ether1 #boot2 ether1 #service ether1 #boot1 ether1 #boot2 ether1 #service Syndey _en1 en1 Syndey _svc 100.10.11.10 255.255.255.0 192.168.2.13 255.255.255.0 100.10.1.11 255.255.255.0 100.10.11.11 255.255.255.0 192.168.2.14 255.255.255.0 ether1 #Persistent 192.168.2.10 255.255.255.0 ether1 #Persistent 192.168.2.12 255.255.255.0 3.2 hosts文件设置

主机名和节点名对应，/etc/hosts文件中必须要有主机名对应的IP 每台服务器都要修改

100.10.1.10 Syndey_en0 #boot1 100.10.11.10 Syndey_en1 #boot2 192.168.2.10 Syndey #Persistent 192.168.2.12 Syndey_svc #service 100.10.1.11 Perth_en0 #boot1 100.10.11.11 Perth_en1 #boot2 192.168.2.11 Perth #Persistent 192.168.2.13 Perth_svc #service 由于POWERHA7.1要求配置cluster前主机名能解析。通过下面方法确认： # hostname|xargs ping <<正常返回就可以

PING Syndey: (100.10.1.10): 56 data bytes 64 bytes from 100.10.1.10: icmp_seq=0 ttl=255 time=0 ms 如果主机名要与persistent对应，要先设置个IP别名。

Syndey#ifconfig en0 192.168.2.10 alias Perth#ifconfig en0 192.168.2.11 alias 3.3 配置/etc/cluster/rhosts文件

这个文件是7.1的新增（必须）。 每台服务器都要修改

100.10.1.10 100.10.11.10 192.168.2.10 192.168.2.12 100.10.1.11 100.10.11.11 192.168.2.11 192.168.2.13 修改完/etc/cluster/rhosts后用，refresh -s clcomd命令更新配置

3.4 准备repository disk和共享存储

通过下面命令设置repository disk 的PVID。集群主机都要设置。

chdev –l hdisk –a pv=yes 通过下面方式设置共享存储（可以略过，集群配置好后通过C-SPOC设置）

A主机：创建卷组 B主机：导入卷组 4 创建群集
