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http://www.aixchina.net/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。
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
2.1 license
上传license文件HDS HDLM AIX.plk到/var/tmp,并改名为hdlm_license
[test2:root:/] cd /var/tmp
[test2:root:/var/tmp] ls
.oracle dpid2.log oradiag_oracle snmpdv3.log
HDS HDLM AIX.plk hostmibd.log slp_srvreg.lock snmpmibd.log
aixmibd.log installpbx-2228732-031811161323.log snmpd.log
[test2:root:/var/tmp] mv "HDS HDLM AIX.plk" hdlm_license
[test2:root:/var/tmp] ls
.oracle hdlm_license oradiag_oracle snmpdv3.log
aixmibd.log hostmibd.log slp_srvreg.lock snmpmibd.log
dpid2.log installpbx-2228732-031811161323.log snmpd.log
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_072001.iso -o "-V cdrfs -o ro" -m /mnt
unmount ISO镜像:
#fuser -cuk /mnt
#unmount /mnt
[test2:root:/var/tmp] cd /mnt
[test2:root:/mnt] ls
