2008年我开始用了VMware以后 2年我帮公司省了 4000万服务器的采购款 这还丌包含R6的MA跟软件的维护费用 X86加了VMware以后的可靠性超过AIX加上Power VMware 是大才小用 它真正的价值在可靠性 丌是省那些CPU 那 些 x86 的 cpu 没几个钱 Stephen 程总 您是说VMware 加上 x86 可靠性超过小机吗 程总 是啊 远远超过 我们过去几年出的事故都是小机 几乎没有x86 AIX 数 据 库 PowerVM Hypervisor HA CMP Pwr HA 应 用 Novell 等等 ESX HA 数 据 库 应 用 AIX 数 据 库 PowerVM Hypervisor HA CMP Pwr HA 应 用 Novell 等等 ESX HA 数 据 库 应 用 一样的硬件 但是 x86虚拟化平台提供更好的可用性 AIX AIX 要丌断的保持一致性 SUSE 服务器的可靠性依赖的是高可用的软件 IT 管理员 因为领导要求零事故啊 领导 我们 RS 6000 从来都没有事故啊 Step 1 Install the PowerHA softwareYou can purchase this software from IBM directly see Resources for a link the file sets all start with the word cluster Use the installp command to install the software much like any other licensed program package LPP Step 2 Edit some flat filesPut all of the IP addresses associated with the cluster boot persistent and service into each etc hosts file on each node of the cluster Do the same with the usr es sbin cluster etc rhosts file Verify that the server hostnames match the appropriate IP addresses the server s hostname should also match with the persistent IP address Step 3 Configure the boot IP addressesRun the smitty chinet command and set the boot IP addresses for each network adapter Make sure that you are able to ping and connect freely from node to node on all respective networks Also double check to make sure that the default route is properly configured If it isn t run smitty tcpip go into the Minimum Configuration menu enter the default route for the primary adapter and press Enter Step 4 Make application start and stop scriptsCreate two simple Korn shell scripts one that starts an application and one that stops an application Keep these scripts in identical directories on both nodes Step 5 Define the clusterRun the command smitty cm config an hacmp cluster menu dmn Then define the cluster including naming it appropriately Step 6 Define the nodesRun the command smitty cm config hacmp nodes menu dmn Define every node within the cluster on both nodes Step 7 Define the networksRun the command smitty cm config hacmp networks menu dmn This defines one network per Ethernet adapter I prefer to use the Pre defined option as opposed to the Discovered path but that is up to your discretion Check the subnet masks for consistency Step 8 Define the boot IP addressesRun the command smitty cm config hacmp communication interfaces devices menu dmn This defines the boot IP addresses on the respective network adapters This address should be the same IP addresses you used in step 3 Make sure you define these addresses within the proper respective PowerHA defined network Step 9 Define the persistent IP addressesRun the command smitty cm config hacmp persistent node ip label addresses menu dmn This defines the persistent IP addresses again paying attention to pick the proper respective PowerHA defined network Step 10 Define the service IP addressesRun the command smitty cm config hacmp service ip labels addresses menu dmn This defines the service IP addresses Step 11 Perform a discovery and rebootBy this point the nodes should have the ability to communicate with each other and keep the information stored in the nodes Object Data Managers ODMs in sync Make the nodes within the cluster communicate with each other by running the command smitty cm extended config menu dmn Select the Discover PowerHA related Information from Configured Nodes option and check for errors to fix Generally rebooting each node can clear up any minor problems and this is a good point to test restarting each server anyway Step 12 Define the resource groupRun the command smitty cm hacmp extended resource group config menu dmn Define the resource group Then perform these steps Select all participating nodes in the cluster Set the Startup Policy to Online On First Available Node Set the Fallback Policy to Never Fallback This setting prevents the resources from going back to the original server when it is brought up which is a wise thing to do Step 13 Create a shared volume groupNote Run this command only on one node Run the smitty cl vg command and create a shared volume group When you create a shared volume group you only need to select one of the nodes because the disk is shared Step 14 Create a heartbeat diskFirst run the smitty cl convg command and then select Create a Concurrent Volume Group with Data Path Devices Choose one node and the target disk Next run the command smitty cm config hacmp communication interfaces devices menu dmn Repeat step 7 except this time select the Discovered option and the target disk Step 15 Define an application serverRun the command smitty cm cfg app extended This defines an application server for an application that PowerHA will manage Use the scripts you created in step 4 Step 16 Configure the resource groupNote Run this command on only one node Run the command smitty cm hacmp extended resource group config menu dmn Select the Change Show Resources and Attributes for a Resource Group option Then perform these steps Select the appropriate service IP addresses Select the appropriate shared volume groups and heartbeat disk Select the appropriate application servers Step 17 Perform a synchronizationSynchronize the cluster configuration Run the command smitty cm ver and sync Set Automatically correct errors found during verification to Interactive Correct any problems along the way Step 18 Start the clusterAt this point the cluster is ready to start On one of the nodes run the smitty clstart command and pick that particular node My preference is not to have the cluster start on reboot because if there is a PowerHA related problem on startup it can be difficult to troubleshoot it After the node comes up with the resources available start the cluster on the other node Step 19 Perform a test failoverThe best way I have found to test PowerHA s adaptability is to reboot the active node and let things fail over naturally while running the tail f tmp hacmp out command on the other node to watch as things go over Or run the command smitty cl resgrp move node site Select the Move Resource Groups to Another Node option Step 20 Perform failure testingIf you really want to make sure your cluster is solid perform testing by literally emoving cables and seeing how the resources move back and forth The more you test the more reliable your cluster will be Step 1 Install the PowerHA Step 2 Edit some flat files Put all of the IP addresses associated with the cluster boot persistent and service into each etc hosts file on each node of the cluster Do the same with the usr es sbin cluster etc rhosts file Verify that the server hostnames match the appropriate IP addresses the server s hostname should also match with the persistent IP address Step 3 Configure the boot IP addresses Run the smitty chinet command and set the boot IP addresses for each network adapter Make sure that you are able to ping and connect freely from node to node on all respective networks Also double check to make sure that the default route is properly configured If it isn t run smitty tcpip go into the Minimum Configuration menu enter the default route for the primary adapter and press Enter Step 4 Make application start and stop scripts Create two simple Korn shell scripts one that starts an application and one that stops an application Keep these scripts in identical directories on both nodes Vmware HA 保障关键应用 VMware解决了AIX的 四大 IT 难题 1 没有容错功能 2 没有系统飘移功能 VMotion 3 没有基亍PowerVM的灾备解决方案 4 电力紧缺 5 超低使用率 6 丌支持开源软件 7 HACMP PowerHA
