➢修改HBA卡属性：⏹方法一：适用于可以删除子设备时方法二：适用于设备忙时，重启生效2.3安装软件最简安装包（待测试）3设置网络相关3.1网卡IP设置3.2hosts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由于POWERHA7.1要求配置cluster前主机名能解析。
通过下面方法确认：如果主机名要与persistent对应，要先设置个IP别名。
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。
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）4创建群集4.1初始化群集#smitty sysmirror or smitty hacmp➢Cluster Nodes and Networks➢Initial Cluster Setup (Typical)➢Setup a Cluster, Nodes and NetworksSetup Cluster, Nodes and Networks (Typical)Type or select values in entry fields.Press Enter AFTER making all desired changes.[Entry Fields]* Cluster Name [australia]New Nodes (via selected communication paths) [perth] + Currently Configured Node(s) sydney4.2定义Repository Disk如果上一步没有自动创建,要手动创建。
