smitty hacmp Extended Configuration Extended Topology Configuration Configure HACMP Networks Add a Network to the HACMP Cluster * NetworkName net_ether_01 * 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 Add a Network to the HACMP Cluster * NetworkName net_rs232_01* Network Type rs232 4.1.3.3 创建磁盘心跳网络 # smitty hacmpExtended Configuration Extended Topology ConfigurationConfigure HACMP Networks Add a Network to the HACMP Cluster* Network Name net_diskhb_01* Network Type diskhb 4.1.4 添加网络到Cluster4.1.4.1 创建IP通信接口 #

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/AddressConfigurable 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HACMP6.1 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。注：本文主要以介绍HACMP的配置为主，对于HACMP中所使用VG的配置及HACMP的安装方法由于网上有很多非常规范的文档，这里就不再做讲解，请自行查看资料。
