一、环境
1、服务器：HP DL360（HBA卡）
2、确保服务器和EMC的光纤交换机连接正常
3、系统的selinux和iptables最后关闭
二、软件安装
1、Navisphere agent的安装
rpm -ivh naviagent-6.28.20.1.40-1.noarch.rpm
2、PowerPath的安装
rpm -ivh EMCPower.LINUX-5.6.0.00.00-143.RHEL5.x86_64.rpm
3、注册POWERPATH
#emcpreg –install
=========== EMC PowerPath Registration ===========
Do you have a new registration key or keys to enter? [n]
输入y，按回车继续。
Enter the registration key(s) for your product(s),one per line, pressing Enter after each key.After typing all keys, press Enter again.
Key (Enter if done): BYPK-6B4U-MFCE-QAW4-MP97-M9Y6
输入powerpath注册码，然后按回车继续，成功后会显示以下提示信息。
1 key(s) successfully added.
Key successfully installed.
*license key在一张纸上， 和设备及软件光盘介质一起到货*
或者你也可以从已经安装了的系统上查看key：
[root@navy tmp]# powermt check_registration
Key BAP4-6B4H-GFCX-QSR3-M997-E7N6
Product: PowerPath
Capabilities: All
4、启动Navisphere和PowerPath
[root@navy tmp]# /etc/init.d/naviagent;/etc/init.d/PowerPath start
三、在EMC上注册次服务器，划分lun给该服务器，正常的话在系统执行如下命令，可以看到指定的lun
[root@navy tmp]# powermt display dev=all
