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
/opt/DynamicLinkManager/bin/dlnkmgr view -sys
/opt/DynamicLinkManager/bin/dlnkmgr view -lu
/opt/DynamicLinkManager/bin/dlnkmgr view -drv
/opt/DynamicLinkManager/bin/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。

解决办法

通过使用dlmchname.conf文件来实现LUN的绑定

[root@dsdb1 ~]# /opt/DynamicLinkManager/bin/dlmchname -o
KAPL12374-I This operation will change the HDLM device configuration. Do you want to continue? [y/n]:y
KAPL12379-I The utility for changing HDLM device names finished normally.
[root@dsdb1 ~]#

[root@dsdb1 ~]# cat /etc/opt/DynamicLinkManager/dlmchname.conf
# The device name change definition file
# This file is generated by dlmchname
# Format: <S/N> <LUN> <New HDLM device>
#   S/N: Serial number of storage system
#   LUN: LU number
#   New HDLM device: New logical device file name of HDLM device
# Example: 171722 0002 sddlmaa
# For more information on how to modify this file,
# refer to the HDLM user's guide

权限绑定（下面的方式几乎通用）

#vi /etc/udev/rules/50-udev.rules
SUBSYSTEM=="block", KERNEL=="sddlmaa", GROUP="asmadmin", OWNER="orgrid", MODE="0660"

#udevadm control --reload-rules
#start_udev
#ls -l /dev/sddlmaa
