RHEL 6.5环境
1、官网下载的文件为：EMCPower.LINUX.6.xxxx.tar.gz (通过解压#tar -xvf EMCPower.LINUX.6xxxx.tar.gz得到安装文件)
选择系统版本相对应的安装包。
EMCPower.LINUX-6.0.1.00.00-043.RHEL6.x86_64.rpm
2、安装EMCPower.LINUX-6.0.1.00.00-043.RHEL6.x86_64.rpm
[root@lk /]# chmod 777 EMCPower.LINUX-6.0.1.00.00-043.RHEL6.x86_64.rpm
[root@lk /]# rpm -ivh EMCPower.LINUX-6.0.1.00.00-043.RHEL6.x86_64.rpm

*** IMPORTANT ***
Please check the following configurations before starting PowerPath:
- Add _netdev to /etc/fstab mount options for PowerPath pseudo devices.
- Ensure netfs service is started.
netfs service is needed to mount devices with _netdev option.
- Set LVM filter in /etc/lvm/lvm.conf according to PowerPath recommendation.
- Blacklist all devices in /etc/multipath.conf and stop multipathd service.
- Install PowerPath license(s) and ensure that policy is not set to BasicFail
over.
- If no license is available, ensure that only one HBA port is active in the
host.
PowerPath supports only single-HBA configuration when unlicensed.
Refer to PowerPath Installation and Administration Guide for details.
3、为多路径软件注册License（注：license由EMC原厂提供，以下格式仅为说明此操作，非真实License）
查看emcpreg命令使用方法：
[root@lk /]# emcpreg
Usage:
emcpreg [opts] -add key [key ...]
emcpreg [opts] -remove key [key ...]
emcpreg [opts] -check key [key ...]
emcpreg [opts] -list
emcpreg [opts] -edit
emcpreg [opts] -install
Options:
-f file license file
注册License：
[root@lk /]# emcpreg -add key A3DF-3BDD-UHYT-CD6F-EV74-KJUT
Key key is invalid, ignored.
1 key(s) successfully added.
4、使用如下两种方式验证license已经安装成功：
[root@lk /]# emcpreg -list
Key A3DF-3BDD-UHYT-CD6F-EV74-KJUT
Product: PowerPath
Capabilities: All
[ root@lk ~]# powermt check_registration
Key A3DF-3BDD-UHYT-CD6F-EV74-KJUT

[ root@lk ~]# service powerpath status
powerpath: unrecognized service
[root@lk ~]# ps -ef |grep emc

6、安装多路径软件后查看如下：
[root@lk /]# powermt display ports
ERROR: Cannot open PowerPath. Initialization error
经存储工程师建议重启服务器OS：
[root@lk /]# reboot
Broadcast message from root@lk

The system is going down for reboot NOW!
7、重启后查看磁盘聚合状态如下：
