安装多路径软件
[root@dsdb1 /]# yum install -y glibc-
[root@dsdb1 /]# yum install -y libstdc++-
[root@dsdb1 /]# yum install -y libgcc-
[root@dsdb1 /]#cp hdlm_license.plk /var/tmp/hdlm_license
[root@dsdb1 /]#./installhdlm
[root@dsdb1 /]#reboot
设置hdlm变量
[root@dsdb1 ~]# cat .bash_profile
PATH=$PATH:$HOME/bin:/opt/DynamicLinkManager/bin:.
[root@dsdb1 ~]#. .bash_profile
如何查看管理HDLM服务
/etc/init.d/DLMManager stop/start/status
管理常用命令
dlnkmgr view -sys
dlnkmgr view -lu
dlnkmgr view -drv
dlnkmgr view -path
dlmcfgmgr -v
日志位置
/var/opt/DynamicLinkManager/log
安装遇到的问题
装完HDLM多路径软件后，发现两边对应的磁盘信息是不一致的。如果不一致，之后安装RAC会碰到很多问题，可以说存储在OS层面的配置是RAC的重中之重，这一步决定你的RAC牢靠不牢靠，然后就是权限管理。
