Dell EqualLogic PS-Series 采用LAN方式和现有网络服务器进行连接. 每个控制器有三个网口可以用作数据传输和网络管理，所有的网口IP地址需要在同一个子网中。
将存储随机串口线连接笔记本串口和存储控制器的控制口，打开计算机的“超级终端”，端口参数如下：
Speed: 9600
Data: 8
Parity: None
Stopbits: 1
Flow control: None
敲回车看到登陆窗口
login: grpadmin
Password: grpadmin
按照下面提示操作

In this example the local disk is /dev/sda
If you are not using LVM, you may use the mount command:
[root]# mount
/dev/sda1 on /boot type ext3 (rw)
Once the local disk is determined, obtain the scsi id of that disk:
[root]# scsi_id -g -u -s /block/sda
36001e4f010fde3000f39f9f6066b384c
Now edit the multipath configuration to enable multipath on your non-local devices:
[root]# vi /etc/multipath.conf
blacklist {
devnode "*"
}
Add the scsi id of your local disk:
blacklist {
wwid 36001e4f010fde3000f39f9f6066b384c
}
Change:
defaults {
user_friendly_names yes
}
To:
defaults {
user_friendly_names no
}
[root]# chkconfig multipathd on
Start multipathd:
[root]# service multipathd start
List multipath devices:
[root]# multipath -ll
