創建配置文件

[root@node2 ~]# cp  /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf /etc/multipath.conf

編輯配，創建磁盤別名

vi /etc/multipath.conf

multipaths { 
multipath { 
wwid 360060e80105ed170057075a700000001
alias data01
} 

multipath { 
wwid 360060e80105ed170057075a700000000 
alias data02 
} 

multipath { 
wwid 360060e80105ed170057075a700000002 
alias data03 
} 

multipath { 
wwid 360060e80105ed170057075a700000007 
alias ocrvote1
}
multipath { 
wwid 360060e80105ed170057075a700000006 
alias ocrvote2 
} 
multipath { 
wwid 360060e80105ed170057075a700000008 
alias ocrvote3 
} 
}

啓動服務

[root@node2 ~]# service multipathd restart
[root@node2 ~]# chkconfig multipathd on
