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，都古力娜扎和张翰
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/
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licen，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。
1问题
磁盘阵列使用的是日立HDS AMS2003，RAID之前就做好了，现在我分配
了4个500G的LUN给一台AIX服务器使用，但在AIX识别时居然重复了4次

2解决过程
2.1licen
上传licen文件HDS HDLM 到/var/tmp，并改名为hdlm_licen
[test2:root:/] cd /var/tmp
[test2:root:/var/tmp] ls
.oracle oradiag_oracle
HDS HDLM slp_
[test2:root:/var/tmp] mv "HDS HDLM " hdlm_licen
[test2:root:/var/tmp] ls

2.2上传HDLM软件镜像文件并加载镜
HDLM软件为一个ISO镜像文件，包含各个平台的HDLM软件，还从来没在AIX
系统中加载过ISO文件，于是马上上网查询，终于找到了一个最简单的办法
mount ISO镜像：
#loopmount -i dlmglm_ -o "-V cdrfs -o ro" -m /mnt
unmount ISO镜像：
#fur -cuk /mnt
#unmount /mnt
2.3安装ODM
[test2:root:/var/tmp] cd /mnt
[test2:root:/mnt] ls

Contents_ HDLM_Linux HDLM_VMware HGLM hcmdslicen2
[test2:root:/mnt] cd HDLM_AIX
