配置永久的IP标识(persistent IP label)
    一个永久的IP标识(persistent IP label)是一个IP别名,它可以被分配给一个群集网络中的指定的节点,并且会一直固定在分配的节点上。
 
  2.永久的IP标识(persistent IP label)的特性:
    (1)一直固定在被分配的节点上(节点绑定)
    (2)作为别名被配置在启动网卡(boot adapter)上
    (3)与已经被配置的服务IP标识(service IP label)或启动IP标识(boot IP label)共同存在
    (4)不需要在节点上安装额外的物理网卡
    (5)不属于任何资源组
    (6)可以被用于在群集中访问指定的节点进行管理工作
    (7)在节点启动后即可用,当HACMP服务停止后也始终保持可用
    (8)在以太网、令牌环网、FDDI以及ATM LANE网络中都可被配置
    (9)不能在SP交换机、ATM传统IP网和串行网络上进行配置
    (10)和配置的服务IP标识(service IP label)和启动IP标识(boot IP label)使用同一块网卡
    (11)如果节点失败,该IP标识不会迁移到群集中的其它节点
    (12)如果网卡失败,它只会迁移到相同网络的同一个节点上的其它网卡
    (13)每个网络的每个节点上只能配置一个永久的IP标识(persistent IP label)
 
  3.子网的要求
    (1)对于使用传统的IPAT的网络(不使用别名)
        a.必须被配置为和网络中该节点上的所有standby IP标识在不同的子网
        b.可以被配置为和网络中该节点上的service IP标识和boot IP标识在相同的子网或者是不同的子网
 
    (2)对于使用别名的IPAT的网络
        a.必须被配置为和网络中该节点上的所有boot IP标识在不同的子网
        b.可以被配置为和网络中该节点上的作为boot网卡别名的service IP标识在相同的子网或者是不同的子网

启动hacmp .
 
 
 
三. Hacmp 的监控和问题诊断
 
1.    Clstat 监控hacmp
首先加路径:/usr/es/sbin/cluster 到/etc/environment  的path 中。
在aix5.2 下要对snmp  做一些调整才可以看到真正的hacmp的状态。
具体来说, aix 5.2 的 snmp 默认是version 3 :
 
test2:/usr/sbin>ls -l |grep snmp
lrwxrwxrwx   1 root     system            8 Apr 08 17:55 clsnmp -> clsnmpne
-rwxr-x---   1 root     system        83150 Mar 12 2003  clsnmpne
-rwxr-x---   1 root     system        55110 Mar 12 2003  pppsnmpd
lrwxrwxrwx   1 root     system            9 Apr 08 17:55 snmpd -> snmpdv3ne
 
而hacmp 只支持snmp version 1 . 所以我们要做一下调整:
 
stopsrc -s snmpd                                                            
/usr/sbin/snmpv3_ssw -1
startsrc -s snmpd
 
test2:/usr/sbin>ls -l |grep snmp
lrwxrwxrwx   1 root     system           18 Apr 21 13:40 clsnmp -> /usr/sbin/clsnmpne
-rwxr-x---   1 root     system        83150 Mar 12 2003  clsnmpne
-rwxr-x---   1 root     system        55110 Mar 12 2003  pppsnmpd
lrwxrwxrwx   1 root     system           17 Apr 21 13:40 snmpd -> /usr/sbin/snmpdv1
 
2. 启动hacmp时选择:
 
                                                  
*  Start now, on system restart or both[m           now                                                                 
  Start Cluster Services on these nodes              [test2]                                                              
  BROADCAST message at startup?                true                                                                
  Startup Cluster Lock Services?                   false                                                               
  Startup Cluster Information Daemon?            true                                                               
  Reacquire resources after forced down ?            false
 
 
 
 
2.    执行clstat
