19、ESTHA1TESTHA2 TESTHA_svc TESTHA1_boot1 TESTHA1_boot2 TESTHA2_boot1 TESTHA2_boot2修改完/etc/cluster/rhosts后用，使用以下命令刷新配置refresh -s clcomd§1.2.4 配置boot地址配置集群内两台主机的boot地址。TESTHA1#smit chinet Network Interface Name en1 INTERNET ADDRESS (dotted decimal) 192.168.1.1 Network MASK (hexadecimal or dotted de

22、address/usr/es/sbin/cluster/etc/clhosts 注释IPv6解析#:1 # PowerHA SystemMirror§1.2.6 修改EMC存储锁脚本安装EMC第三方存储驱动之后，会自动在HA里添加custom disk method共享锁快速判断和快速解锁脚本。在配置前，检查此选项已有emcpowerreset的脚本。smit sysmirroràCustom Cluster Configurationà Resourcesà Custom Disk Methodsà Change/Show Custom Di

23、sk Methods如锁脚本不存在，则按下图所示手工配置。§1.2.7 修改外置共享盘参数分别对两台主机共享的心跳盘做参数调整，命令如下：chdev -l hdiskpower0 -a reserve_policy=no_reserve§1.2.8 配置共享磁盘l 在主备机两端落实共享磁盘的识别cfmgr -v # 识别磁盘powermt display # 检查已识别的磁盘powermt display dev=all # 检查多路径状态l 在主机侧建立共享VG与文件系统FS(步骤略)注：如互备架构，需要复核以下jfs2的loglv命名是否按规范调整。（不可使用默认的lo

24、glv00）l 主机侧获取共享VG的major NO.rootTESTHA2:/>ls -l /dev/datavgcrw-rw- 1 root system 40, 0 Oct 13 16:20 /dev/datavgls -l /dev/<vgname>后, 第五列数字为major NO.,上例中, major NO.为40。l 主机侧获取共享VG的pvid输入lspv，以获取pvid信息。输出第二列为pvid，第三列为vgname。l 备机侧同步共享VG备机侧通过imporvg命令导入共享VG/usr/sbin/importvg -V <major> -y

25、<vgname> -n <vg内任意一块pv的pvid>-V vg major NO.-y vgname-n 导入后不立即varyonl 共享VG检查在主备机侧均输入lspv，以获取pvid信息进行比较。两侧除rootvg外，PVID应该一致。§1.2.9 建立应用启停脚本手工在两个节点上建立“/usr/sbin/cluster/events/startha.sh”“/usr/sbin/cluster/events/stopha.sh”等脚本，并保证其有权限为744。其中，/usr/sbin/cluster/events/表示启停脚本的路径，需要放在内置磁盘上

26、，保证共享vg在offline状态时，启停脚本仍然可读。§1.3 搭建集群*以下操作，如无特殊标注，均在主机侧实施。§1.3.1 配置网络拓扑§1.3.1.1 创建Cluster通过smit sysmirror菜单建立sysmirror的cluster:smit sysmirror à Custom Cluster ConfigurationCluster Nodes and NetworksInitial Cluster Setup (Custom)ClusterAdd/Change/Show Cluster * Cluster Name TEST_c
