HDLM 提供主机到存储系统的I/O 通道负载平衡和故障切换功能；增强了主机系统的数据可得性。
虽然存储系统通过RAID 技术对数据进行了保护，但是单纯的存储系统是不能够提供整个I/O 系统的端到端的保护的。
主机端到存储系统的整个I/O 路径中发生了故障如：HBA 失效、FC 交换设备故障、连接电缆断开等会中断主机端对数据的访问；HDS 公司提供的HDLM 软件，通过对主机到存储的冗余I/O 路径的管理实现负载均和故障切换；保证了24×7业务不间断的运行。
1.2 HDLM 软件特点高可靠：通过服务器的多条通道实现I/O 通道自动的故障切换和恢复回切提高了服务器端数据访问的安全性和性能。
高性能：通过多条I/O 通道的负载均衡提高了应用系统数据访问的性能，进而有效改善了应用系统的性能。
易安装：HDLM 能够自动查寻主机端到存储端的路径，这种查寻无论是直连的DAS结构还是复杂的SAN 结构都可以自动完成。
因此HDLM 安装完成后不需要复杂的配置就可以使用了。
1.3 HDLM 软件工作方式HDLM 对I/O 通道进行实时控制，检测每个通道的状态；当有任何一个通道发生故障时自动将I/O切换到其它健康的通道上；同时，HDLM会自动记录整个操作过程。

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
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.5.3.0.1.tar.Z，通过FTP传到AIX上。
使用binary的方式传，否则无法解压。
2、gzip –d，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 Software; IBM Fibre Channel 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。

解决AIX下识别HDS磁盘阵列多路径问题公司有台日立HDS AMS2003磁盘阵列，基本还没怎么使用，于是尝试分配了4个500G的LUN 给一台测试服务器，都做了冗余，每块盘都有4条路径，分配好后在AIX识别出来了，但每块盘都重复了4次。
因为是以前使用的都是IBM的阵列，没发现过有这样的问题，于是发贴求助新划的磁盘阵列，lspv显示重复了4次/club/thread-78460-1-1.html 通过查询资料确定了是多路径的问题，需要用到HDLML软件，印象中听日立原厂的工程师提到过，于是QQ联系日立原厂工程师拿到了安装介质及license，并在指导下解决了问题，以下是我根据记录的日志整理的步骤。

HDS-HDLM多路径的管理软件aix
1. 多路径的管理软件Dynamic Link Manager是HD配合各个主机厂家在主机高可用系统运行结构中提供的独特软件，安装在主机上，需要存储系统微码支持。
它使用最优的调度算法使连接主机与磁盘阵列的各I/O通道间的I/O自动达到均衡，这样可提高系统的I/O吞吐量，提高整个系统的性能。
Dynamic Link Manager另一个功能是I/O通道故障自动隔离。
当主机与磁盘系统之间的I/O通道在链路环节上出现故障（如HBA^、交换机、光缆、接口卡），Dyn amic Link Man age能实现自动故障隔离，即切换至另一通路，应用I/O可以在正常的通道上继续进行，确保生产业务的连续性。
当故障通道修复或替换完毕后，可在线激活，重新开始在原通路上工作。
HDLMT以在IBM AIX、SUN Solaris、Microsoft Windows NT/2000、Linux 及HP-UX?多种平台上提高系统的可靠性。
并支持其他的高可靠性（HA软件，如HACMPSUN CLUSTER VCS MC等。
在没有多路径功能支持下，主机只能通过某一个路径访问一个磁盘（LUN，系统存在单点故障的隐患。
当该路径上的任何一个环节出现问题时，如主机HB/卡损坏、光纤或光纤交换机损坏等情况下，会造成主机无法访问磁盘的现象，而导致用户系统的中断。
在多路径软件（如HDLM的支持下，使用多条路径连接主机和存储系统，主机可以通过多个路径访问同一个磁盘，避免出现单点故障，提高整个系统的可靠性。
1.1. HDLM勺主要功能• 负载均衡（Load balancing ）当多条路径连接主机和存储系统时，HDL把负载分配到各个路径，避免单个路径负载繁重而影响处理速度Legend:: Fiber cable or SCSI cabfe----------- :PlrysicBl paUl* 路径切换(Path Failover )当多条路径连接主机和存储系统时，如果某条路径出现错误，HDL 将把业务切换到其它活动的路径，保证系统不中断下业务的延续。

HDLM、Powerpath共存环境XP磁盘路径故障问题解决
总结：1.当HDLM、Power path多链路管理软件共存在一套主机环境中时，即便是原来经HDLM管理的磁盘Power path也仍然可以进行管理，容易造成混淆，在未来类似环境中一定要提前合理规划磁盘的管理方式和操作步骤;2.HDLM管理的磁盘，存在一种reserve状态，可以保护意外性的误操作（在LUNManager中意外删除路径）；过程：出于测试目的，分配了部分LUN给IBM主机，然而该主机属于测试系统，上面安装了多种多链路软件(EMC PowerPath, HP HDLM等)，当系统管理员SA要求存储系统管理员SSA释放存储中该磁盘(unmap)后，SSA确认SA将磁盘设备文件删除后，通过SVP LUN Manager进行LUN的unmap操作。

Functional differences between versions of HDLM -Hitachi Command Suite Dynamic Link Manager (for AIX) User Guide Chapter B. Differences between HDLM version 5.9 or later and version5.8.1 or earlierAdditional usage precautions(1) Version numbers to be displayed after this version of HDLM is installed are as follows:(2) The following example shows the text displayed when dlnkmgr view -sys is executed:(3) Notes on HAM environments- In the case of displaying the LU information, the HAM information is not output by specifying the "all" parameter-value for the HDLM command. Specify the "ha" and "hastat" parameter-value instead.- An online operation is performed on an owner path, a non-owner path's status may change to Offline(E). After performing an online operation on an owner path, use the HDLM command to make sure that the non-owner path's status is Online.If the non-owner path's status is Offline(E), change the status of HAM pairs to PAIR, and then perform an online operation on the Offline(E) path again.- When you set up a HAM pair to be managed by HDLM, make sure that the host recognizes paths to the MCU (Primary VOL) and RCU (Secondary VOL) after the HAM pair is created.Execute the dlnkmgr view -lu -item hastat operation. If ha is not displayed in the HaStat column, then the corresponding LU is not recognized as being in a HAM configuration.If the host recognizes the paths to the MCU and RCU before the HAM pair iscreated, restart the host after the HAM pair is created.- If you release a HAM pair to recover the system after a HAM volume failure, do not restart a host that is connected to the MCU and RCU while the HAM pair is released.If you need to restart the host while the HAM pair is released, disconnect allpaths to the MCU and RCU, restart the host, re-create the HAM pair, and then reconnect the paths.If you restart a host that is connected to the MCU and RCU while the HAM pair is released, the RCU volume will be recognized as a volume other than an MCUvolume. If this occurs, restart the host after the HAM pair is re-created.Execute the dlnkmgr view -lu -item hastat operation, and then confirm that ha is displayed in the HaStat column.DocumentationAvailable documentsDocumentation errataNone.Appendix AHost Bus Adapter (HBA) Support MatrixUse the SCSI I/F adapter or Fibre Channel I/F adapters listed below. When using two or more adapters, use the same type of adapter. If you combine different types of HBA, HDLM may not be able to switch a path when an error occurs.The combination of HBA which can exist together is as follows.- FC5716, FC1977 and FC1957- FC5758 and FC1905- FC5759 and FC1910(*1): HBA hot swap is not supported for this HBA because this HBA is not asupported hot plug.Copyrights and licenses© 2016, Hitachi, Ltd.

1.多路径的管理软件Dynamic Link Manager是HDS配合各个主机厂家在主机高可用系统运行结构中提供的独特软件，安装在主机上，需要存储系统微码支持。
它使用最优的调度算法使连接主机与磁盘阵列的各I/O通道间的I/O自动达到均衡，这样可提高系统的I/O吞吐量，提高整个系统的性能。
Dynamic Link Manager另一个功能是I/O通道故障自动隔离。
当主机与磁盘系统之间的I/O通道在链路环节上出现故障(如HBA卡、交换机、光缆、接口卡)，Dynamic Link Manager能实现自动故障隔离，即切换至另一通路，应用I/O可以在正常的通道上继续进行,确保生产业务的连续性。
当故障通道修复或替换完毕后,可在线激活,重新开始在原通路上工作。
HDLM可以在IBM AIX、 SUN Solaris、Microsoft Windows NT/2000、Linux及HP-UX等多种平台上提高系统的可靠性。
并支持其他的高可靠性（HA）软件，如HACMP、SUN CLUSTER、VCS、MCS等。
在没有多路径功能支持下，主机只能通过某一个路径访问一个磁盘（LUN），系统存在单点故障的隐患。
当该路径上的任何一个环节出现问题时，如主机HBA卡损坏、光纤或光纤交换机损坏等情况下，会造成主机无法访问磁盘的现象，而导致用户系统的中断。
在多路径软件（如HDLM）的支持下，使用多条路径连接主机和存储系统，主机可以通过多个路径访问同一个磁盘，避免出现单点故障，提高整个系统的可靠性。
1.1.HDLM的主要功能负载均衡（Load balancing）当多条路径连接主机和存储系统时，HDLM把负载分配到各个路径，避免单个路径负载繁重而影响处理速度。
∙路径切换（Path Failover ）当多条路径连接主机和存储系统时，如果某条路径出现错误，HDLM将把业务切换到其它活动的路径，保证系统不中断下业务的延续。
∙路径回复（Failback）当一个故障路径回复可用时，HDLM将把该路径恢复为Online，保证最大数目的路径可用和分担负载。
∙路径健康检查（Path health checking）HDLM按用户既定的间隔自动检查所有路径的状态，因此不必手工定期不断地检查路径的状态。
∙错误管理（Error management）HDLM的错误管理功能按照错误级别过滤错误信息，并将错误信息保存在记录文件里。
1.2.HDLM的配置在完成HDLM软件的安装以后，并且已经正确的认到相应的HDLM设备（类似于chxtydz的设备）以后，需要对HDLM进行几个参数的调整：1.3.安装和配置HDLM∙Log in to AIX® as the root user.telnet∙Directly under /var/tmp/, save the license key file ashdlm_license(/var/tmp/hdlm_license).∙Insert the HDLM CD-ROM into the CD-ROM drive.

∙通过命令查看磁盘读写状态。
可以看到两条路径都有流量，且基本平衡。
这是负载均衡功能（Load Balance）。
∙断开一条路径，磁盘IO转移到另一条路径继续访问，作业没有中断。
这是路径切换功能（Path Failover）。
∙重新连接被断开的路径，执行# /opt/DynamicLinkManager/bin/dlnkmgr online使所有路径回复正常，此时磁盘IO回复到原来的路径访问。
这是路径自动恢复功能（Auto Failback）。
1.4.2.HDLM 帮助●Help OperationFormat:/opt/DynamicLinkManager/bin/dlnkmgr help [operation-name] [operation-name] ...Description: The dlnkmgr help command displays the list of operations available for the HDLM command, or the format of individual operations.Parameter:operation-name: Specify the name of the HDLM command operation whose format youwant to know. You can check the format of multiple operations at one time byspecifying multiple operation names. When multiple operation names are specified, the help operation displays the format for the corresponding operations in the order they were entered.If you do not specify any operation names, the help operation displays the names of all operations available for the HDLM command.Examples:# /opt/DynamicLinkManager/bin/dlnkmgr help# /opt/DynamicLinkManager/bin/dlnkmgr help onlineHelp ParamaterTyping the operation name followed by –help will display the format of that operation (other than for the help operation). The following example shows how to display theformat of the clear operation.# /opt/DynamicLinkManager/bin/dlnkmgr clear -help/usr/DynamicLinkManager/bin/dlnkmgr view –drv | grep –w清标志位:dlmpr -c (用于数据迁移)启动HDLM#startsrc –s DLMManager停HDLM#stopsrc –s DLMManager删除DLM设备#/usr/DynamicLinkManager/bin/dlmrmdev –AUnload HDLM1.#/usr/DynamicLinkManager/bin/dlmrmdev –A2.#rmdev –dl fcs0/1 -R3.#installp –u DLManager相关Aix命令扫描设备#cfgmgr –v扫描设备当配置完HDS（mapping）后，在Aix扫出该设备显示HBA卡信息#lscfg –vl fcs0 ( 可显示HBA卡特别是WWN的信息)Part Number.................09P5079EC Level....................ASerial Number...............1C22508090Manufacturer................001CFeature Code/Marketing ID (2765)FRU Number..................09P5080Network Address.............10000000C92D7711(WWN)这个信息在HDS方面有用，就是绑定Host的WWN(logical status->Setting->Security->Host Group Security->PortA/PortB->Enable后在Port A/B->WWN->Add就可，这样就实现了Port A/B和Host/WWN绑定）删除原dlm磁盘先将mapping去掉#/usr/DynamicLinkManager/bin/dlmrmdev –A(删除dlm磁盘，重配置要)# rmdev -dl hdisk2（dlm启用前的Disk）在dlm上建立文件系统#chdev dlmrdrvxx –a pv=yes(分配ID号)#smitty extendvg(在datavg中加入相应的dlmfdrvxx)#smitty(在datavg建立文件系统)#smitty reducevg(将hdisk从vg中取出)MPIO打包#lsdev -Cc disk 后有MPIO说明MPIO起作用，需打包#mkdir cdrom#mount -r -v cdfrs /dev/cd0 /cdrom#cd /cdrom/aix_odm/V5.0.0.1#smitty install_latest# cd /cdrom/aix_odm/V5.0.1.4U#smitty install_latest# cd /cdrom/aix_odm /V5.0.52.1U#smitty install_latest#cd#umount /cdrom如Aix 的MPIO起作用要打包（Aix 5.2有要求）#lsdev –Cc disk显示有MPIO FC fSCSI说明MPIO起作用了，需要打包(Aix V5.2需要) 安装odm包：#mkdir /cdrom#mount –r –v cdrfs /dev/cd0 /cdrom#cp /cdrom/HDS*.bff /usr/sys/inst.images#cd /usr/sys/inst.images#inutoc .#smitty installa) Select option “Install and Update Software”b) Select option “Install and Update from LATEST Available Software”c) When prompted for Input Device, enter the directory the fileset was copied tod) Use the F4 key to list packages to installe) Select a package by using the F7 key and press enter#lsdev –Cc disk再显示时就是HDLM的信息安装HDLM安装license key1.当提供了 license key file 将 license key file Copy到指定目录下/var/tmp/hdlm_license#mkdir cdrom#mount –r -v cdrfs /dev/cd0 /cdrom#cp /cdrom/ license/* .plk /var/tmp/hdlm_license#umount /cdrom安装HLDM介质1.如果从CD直接安装#installp –aXgd /dev/cd0 all2.如果将CD内容Copy 到一个目录上了/tmp/HDLM#installp –aXgd /tmp/HDLM all检查HDLM安装结果1.#lslpp –L DLManager.rte的状态status=C(commit)就OK2.#cfgmgr3.#lsdev –C|grep dlmDlmdrv Available HDLM Alert DriverDlmdrv0 Available HDLM Driver说明HDLM起作用了HDLM相关命令1.在相关登录用户的.profile中+上PATH=$PATH:/usr/DynamicLinkManager/binExport PATH就可登录后执行DLM命令了显示HDLM版本信息# /usr/DynamicLinkManager/bin/dlnkmgr view -sysHDLM Version : 05-80Service Pack Version :Load Balance : on(rr)Path Health Checking : on(30)Auto Failback : off设置自动容错Set Auto Failback=ON# /usr/DynamicLinkManager/bin/dlnkmgr set -afb on –intvl 10 设置系统检查PATH时间Set healthe checking time#/usr/DynamicLinkManager/bin/dlnkmgr set -pchk on -intvl 1 检查PATH状态Check path status View Path# /usr/DynamicLinkManager/bin/dlnkmgr view -path -lu显示dlm/hdisk对应的PathId和HBA/CHAChaPort对应CHA#/usr/DynamicLinkManager/bin/dlnkmgr view -item –luProduct : 9500VSerialNumber : 7572LUs : 48iLU SLPR HDevName Device PathID PathName ChaPort CLPR Sh0018 - ch6t0d0 c6t0d0 000000 0002.0000.0000000000060000.0000 0B - O0c8t0d0 000048 0003.0000.0000000000080000.0000 1A - O00019 - ch6t0d1 c6t0d1 000001 0002.0000.0000000000060000.0001 0B - O1 c8t0d1 000049 0003.0000.0000000000080000.0001 1A - O1 0020 - ch6t0d2 c6t0d2 000002 0002.0000.0000000000060000.0002 0B - O2 c8t0d2 000050 0003.0000.0000000000080000.0002 1A - O2 0021 - ch6t0d3 c6t0d3 000003 0002.0000.0000000000060000.0003 0B - O3 c8t0d3 000051 0003.0000.0000000000080000.0003 1A - O3 0022 - ch6t0d4 c6t0d4 000004 0002.0000.0000000000060000.0004 0B - O4 c8t0d4 000052 0003.0000.0000000000080000.0004 1A - O4 0023 - ch6t0d5 c6t0d5 000005 0002.0000.0000000000060000.0005 0B - O5 c8t0d5 000053 0003.0000.0000000000080000.0005 1A - O5 0024 - ch6t0d6 c6t0d6 000006 0002.0000.0000000000060000.0006 0B - O6 c8t0d6 000054 0003.0000.0000000000080000.0006 1A - O6 0025 - ch6t0d7 c6t0d7 000007 0002.0000.0000000000060000.0007 0B - O7 c8t0d7 000055 0003.0000.0000000000080000.0007 1A - O7 0026 - ch6t1d0 c6t1d0 000008 0002.0000.0000000000060001.0000 0B - O0显示Aix对应的设备# /usr/DynamicLinkManager/bin/dlnkmgr view -drvPathID HDevName Device LDEV000000 dlmfdrv0 hdisk1 9500V.0051.0005000001 dlmfdrv1 hdisk2 9500V.0051.0015000002 dlmfdrv2 hdisk3 9500V.0051.0020000003 dlmfdrv0 hdisk4 9500V.0051.0005000004 dlmfdrv1 hdisk5 9500V.0051.0015000005 dlmfdrv2 hdisk6 9500V.0051.0020KAPL01001-I The HDLM command completed normally.
