EMC磁盘连接AIX的方法及多路径冗余软件POWERPATH安装、配置、测试报告

1、EMC磁盘连接AIX的方法及多路径冗余软 件POWERPATH安装、配置、测试报告 第一、ODM部分2 1、安装前准备工作2 获取EMC ODM文件2 2、安装配置过程2 3、安装后确认3 第二、POWERPATH 部分4 准备工作4 安装配置过程4 性能测试工作5 4、powermt提供的其他功能 24 5、测试环境拓扑图 26 第三、 Appendix : 28 第一、ODM部分 1. 安装前准备工作 说明：一 般情况下， AIX自带的FC驱动也可以让 AIX正常识别出EMC的磁盘，但是会显 示为other FC disk之类，这样powerpath是无法管理的，所以要加装 ODM。 获取

2、EMC ODM 文件 1、下载EMC odm文件，这是针对 emc在aix提供的驱动。下载地址： 2. 安装配置过程 1、下载的文件类型这个名字：EMC.AIX..tar.Z，通过FTP传到AIX上。使用binary 的方式传，否则无法解压。 2、gzip , tar xvf 命令接包。 3、解包之后用installp命令。 4、 安装的时候重点先看看包里面的readme文件，里面重点提到的是不管链接那种EMC 设备都只能安装一种support软件，对于symmetric而言，只能安装如下 3种文件的 任意1种。 EMC Symmetrix FCP Support Softwar

3、e; IBM Fibre Cha nnel driver support. EMC Symmetrix FCP MPIO Support Software; IBM default PCM MPIO support. EMC Symmetrix FCP PowerMPIO Support Software; PowerPath custom PCM MPIO support. （这次测试大部分时间都耗在这个问题上，以前没有认真看readme,把全部的都全部安 装了。一旦把全部安装上， 根本无法识别 sysmmetrix的盘，这样导致了后面的 powerpath 也就无法做了费了 2天时间啊。）

4、 5、安装结果如下： # lslpp -l |grep EMC.* EMC.Symmetrix.aix.rte COMMITTED EMC Symmetrix AIX Support EMC.Symmetrix.fcp.rte COMMITTED EMC Symmetrix FCP Support 6、如果EMC盘已经在系统上被识别出来了比如： # lsdev -Ccdisk hdisk0 Available 11-08-00-2,0 16 Bit LVD SCSI Disk Drive hdisk1 Available 11-08-00-4,0 16 Bit LV

6、e 3A-08-01MPIOOtherFCSCSIDisk Drive 使用了 aix自带的驱动，会显示 MPIO Other FC SCSI Disk Drive 。 7、先删除掉这些hdisk设备，然后重启 AIX。（疑问：应该不用重启，直接运行cfgmgr 也可以把，但测试中发现确实重启才行） 3、安装后确认 1、显示一下disk的名字即可 # lsdev -Ccdisk hdisk0 Available 11-08-00-2,0 16 Bit LVD SCSI Disk Drive hdisk1 Available 11-08-00-4,0 16 Bit LVD SCSI Disk D

10、 E-Lab 按先导来操作 Home Support In teroperability and Product Lifecycle In formatio n E-Lab Interoperability Navigator 安装配置过程 1. 安装过程 上面，然后解压之后使用installp安装。 2. 配置过程 powermt config 简单，一个命令即可 powermt display dev=all 显示 PATH # powermt config powerpath0 created # lspv （hdiskpower*这个设备出现好像要延迟一点时间，不会马上出现，网上还看到

11、说1天 以后才出现的情况。估计是盘比较多，路径运算需要很多时间，此时连接拓扑如图1） hdiskO 000a5e2a167bccb3 rootvg active hdisk1 000a5e2a16a41f2a rootvg active hdisk2 none None hdisk3 none None hdisk4 none None hdisk5 none None hdisk6 none None hdisk7 none None hdisk8 none None hdisk9 none None hdiskIO none None hdiskll none None hdisk12 n
