2、最低版本AIX如下：-AIX 6.1 TL6 或者 TL7-RSCT 3.1通常RSCT软件包都是AIX操作系统自带的，PowerHA的软件安装包中也包含 RSCT软件包。以下AIX文件集是安装PowerHA 7.1所必须的，通常也包含在 AIX的缺省安装中，在安装PowerHA之前一般只需再次确认即可。bos.adt.libbos.adt.libmbos.adt.syscallsbos.ahafsbos.clvm.e nhbos.clusterbos.databos .n et.tcp.clie ntbos .n et.tcp.serverbos.rte.SRCbos.rte .libcbo

4、信。1.3.2 Repository DiskRepository Disk是一个共享的存储LUN，最小设置为1GB。请确保HA的两个 节点都能访问该LUN，并且确保该LUN在存储级别存在数据保护(比如RAID)1.3.3 不支持磁盘和串口心跳PowerH 7.1不再支持传统的磁盘和和串口心跳，而是使用SFWCOM(SAN-basedCommu ni catio n In terface)或者 DPCOM(Ce ntral Cluster Repository-based Com mun icatio n In terface)作为磁盘心跳的替代。SFWCOM即SAN心跳，中间不 需要经过 R

5、epository Disk。DPCOM需要使用Repository Disk的一部分来做心跳 通信。1.3.4 强制采用别名(Alias)方式加载服务IPPowerHA 7.1不再支持IP替换的方式加载service IP,而是强制使用别名方式加 载service IP。因此在规划IP网段的时候需要多规划一个网段。1.3.5 不再支持别名(Alias)心跳PowerHA 7.1不再支持别名心跳。如果需要升级到7.1，请先取消别名心跳。1.3.6 光纤卡参数配置 对于使用SAN心跳(SFWCOM)的光线卡，需要配置如下参数：- dyntrk = yes- fc_err_recov = fast

6、_fail-tme = yes前两个参数需要在fscsi设备上设置。tme是”target mode enabled的缩写，需要在 fcs设备上设置为ye&1.3.7 VG 配置PowerHA 7.1 只支持 Enhanced-Concurrent VG，非 concurrent 的 VG 将不能加入 PowerHA的资源组。1.4 安装可以使用从CD或者NIM服务器进行安装。使用”smit installp”安装即可。第6页共15页第二章 配置PowerHA2.1 创建 Cluster在两个节点的/etc/hosts中添加boot IPs, Service IP和persistent

7、 IP的解析，通常 persiste nt IP对应于主机（节点）名。同时在 /etc/cluster/rhosts中添加两个节点的 主机名，如下所示。完成后需要执行”refresh clcomd”读取新的rhosts配置信息HATEST01;/#tail -12 /etc/hosts # 2000：1：l：l：209：6bff：Feee：2b7Fipbsanple# 丄p6 rtame/address127*0*0*1197.3.137*241loopback loopbacklocalhost localhast* loopbark (lo0)* IPv6 loopbackname/add
