4. 配置HACMP 以下操作只需在一个节点上操作即可
4.1 配置网络拓朴
4.1.1 配置Cluster Name
       # smitty hacmp
         Extended Configuration
     Extended Topology Configuration
       Configure an HACMP Cluster
         Add/Change/Show an HACMP Cluster
* Cluster Name              [testcluster]
4.1.2 配置Cluster节点
      # smitty hacmp
         Extended Configuration
     Extended Topology Configuration

                    *NodeName                         [NodeA]
                     Communication Path to Node          [p630a_boot] +
以同样方法将NodeB添加到Cluster中
                     *NodeName                        [NodeB]
                     Communication Path to Node          [p630b_boot] +
4.1.3 配置HACMP网络

* NetworkType                         ether
* Netmask                            [255.255.255.0] +
* Enable IP Address Takeover via IP Aliases [Yes]        +
                    IP Address Offset for Heartbeating over IP Aliases []
      使用同样的方法创建[net_ether_02]
      * Enable IP Address Takeover via IP Aliases [Yes] 此选项决定了HACMP的IP切换方式，但值得一提的是只有“boot”、“standby”、“service”三个IP分别为三个不同网段时必须选用IP Aliases方式。如果“boot”、“standby”其中一个与“service”为同一个网段时必须选用IP Replace，则此选项应选“NO”。
4.1.3.2 创建串口心跳网络
      # smitty hacmp
         Extended Configuration
           Extended Topology Configuration
             Configure HACMP Networks

      以同样方法创建另一个串口通信设备
                      * Device Name           [rs232_node_b]
* Network Type           rs232

* Device Path                [/dev/hdisk1]
* Node Name                [NodeA] +
    做磁盘心跳的磁盘必须将VG创建为Concurrent模式

4.2 配置HACMP资源
4.2.1 配置资源
4.2.1.1 创建Applications Servers
        # smitty hacmp
         Extended Configuration
       Extended Resource Configuration
             HACMP Extended Resources Configuration
               Configure HACMP Applications Servers
                 Add an Application Server
                   * Server Name          [appserver]
* Start Script         [/hascript/clstart.sh]
* Stop Script           [/hascript/clstop.sh]
需要手动在两个节点上建立“/hascript/clstart.sh”、“/hascript/clstop.sh”并保证其有执行权限。如果是双机互备的话需要建立两个App Server。方法相同。
4.2.1.2 创建Service IP
        # smitty hacmp
         Extended Configuration
       Extended Resource Configuration
             HACMP Extended Resources Configuration
                Configure HACMP Service IP Labels/Addresses
              Add a Service IP Label/Address
Configurable on Multiple Nodes
                  * IP Label/Address                  p630a_svc   +
* Network Name                   net_ether_01
      同样方法配置第二个Service IP
                  * IP Label/Address                  p630b_svc   +
* Network Name                   net_ether_02
      Network Name：“net_ether_01”、“ net_ether_02” 决定了与之对应的Service IP默认在哪个网卡上启动。
4.2.2 配置资源组
4.2.2.1 创建资源组
        # smitty hacmp
         Extended Configuration
       Extended Resource Configuration
         Add a Resource Group
* Resource Group Name                    [rg_node_a]
Participating Nodes (Default Node Priority)    [NodeA NodeB] +
           Startup Policy                 Online On Home Node O> +
           Fallover Policy                Fallover To Next Prio> +
           Fallback Policy                Fallback To Higher Pr> +
如果是双机互备的话以同样方法建立另一个资源组
           * Resource Group Name                    [rg_node_b]
Participating Nodes (Default Node Priority)    [NodeB NodeA] +
“Participating Nodes”选项决定了资源组中节点的优先级，写在前面的节点其优先级高于后面的节点。
根据实际需求决定资源组的：“Startup Policy”、“Fallover Policy”、“Fallback Policy”。
Startup Policy：
Online On Home Node Only：只在主节点启动。在 “Participating Nodes”中写在第一位的节点启动。
Online On First Available Node：在第一个启动的节点启动。在“Participating Nodes”中所选择的所有节点中最先启动的节点上启动。
Online Using Distribution Policy：按照分布策略启动
Online On All Available Nodes：在所有启动的节点中启动。做并发群集时选择此项。如：Oracle RAC
      Fallover Policy：
Fallover To Next Priority Node In The List：节点失败时资源组迁移到下一优先级节点
Fallover Using Dynamic Node Priority：节点失败时动态选择迁移节点
Bring Offline (On Error Node Only)：将资源组下线
      Fallback Policy：
Fallback To Higher Priority Node In The List：节点恢复时资源组返回优先级高的节点
Never Fallback：不进行资源组回迁
4.2.2.2 配置资源组属性
        # smitty hacmp
         Extended Configuration
       Extended Resource Configuration
        Change/Show Resources and Attributes for a Resource Group
             Resource Group Name                         rg_node_a
Participating Nodes (Default Node Priority)        NodeA NodeB
             Startup Policy                                Online On Home Node O>
Fallover Policy                               Fallover To Next Prio>
Fallback Policy                               Fallback To Higher Pr>
Fallback Timer Policy (empty is immediate)        []+
             Service IP Labels/Addresses                     [p630a_svc] +
Application Servers                            [appserver] +
             Volume Groups                               [datavg]+
Use forced varyon of volume groups, if necessary    false+
Automatically Import Volume Groups             ture+
Filesystems (empty is ALL for VGs specified)       []+
Filesystems Consistency Check                  fsck+
Filesystems Recovery Method                   sequential+
Filesystems mounted before IP configured         false+
Filesystems/Directories to Export                []+
Filesystems/Directories to NFS Mount            []
Network For NFS Mount                       []+
Tape Resources                               []+
Raw Disk PVIDs                              []+
Fast Connect Services                          []+
Communication Links                          []+
Primary Workload Manager Class                 []+
Secondary Workload Manager Class               []+
如果是双机互备以同样方法修改另一个资源组属性

5. 校验并同步HACMP配置
    # smitty hacmp
      Extended Configuration
       Extended Verification and Synchronization
         * Verify, Synchronize or Both                            [Both] +
* Automatically correct errors found during                 [Interactively] +
          verification?
* Force synchronization if verification fails?                [No] +
* Verify changes only?                                  [No] +
* Logging                                            [Standard] +
6. 启动/停止HACMP
6.1 启动HACMP（快速路径：#smitty clstart）
# smitty hacmp
    System Management (C-SPOC)
      Manage HACMP Services
        Start Cluster Services
          * Start now, on system restart or both                now
            Start Cluster Services on these nodes              [NodeA NodeB]
* Manage Resource Groups                       Automatically
BROADCAST message at startup?                true
Startup Cluster Information Daemon?              false
            Ignore verification errors?                       falsbe
            Automatically correct errors found during           Interactively
            cluster start?
6.2 停止HACMP（快速路径：#smitty clstop）
# smitty hacmp
    System Management (C-SPOC)
      Manage HACMP Services
        Stop Cluster Services
          * Stop now, on system restart or both             now+
Stop Cluster Services on these nodes             [NodeA NodeB] +
BROADCAST cluster shutdown?               true+
*Select an Action on Resource Groups            Move Resource Groups+

7. 测试HACMP（这里仅为模拟测试）
# smitty hacmp
Extended Configuration
HACMP Cluster Test Tool
    Execute Automated Test Procedure
      Verbose Logging                                   [Yes] +
Cycle Log File                                     [Yes] +
Abort On Error                                     [No] +
执行测试前先将Cluster停止，否则HACMP的启动测试将无法执行。
在执行测试过程中可以使用“tail -f /tmp/hacmp.out”来查看HACMP的日志。
