linux下分配磁盘

在linux安装和配置Initiator

 

挂载

[root@localhost ~]# mkdir/mnt/cdrom

[root@localhost ~]# mount/dev/cdrom /mnt/cdrom

安装包

[root@localhost ~]# cd/mnt/cdrom/

[root@localhost cdrom]#cd Packages/

[root@localhostPackages]# ls iscsi*

iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm

[root@localhostPackages]# rpm -vih iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm

 

在管理控制台新建客户端

在SAN客户端中添加

选中ISCSL下一步

选择Ip地址表下一步

选择或添加分配给客户端的启动器  下一步

一步一步下去一直到完成.

 

完成后输入：

[root@localhostPackages]# iscsiadm -m discovery -t sendtargets -p 192.168.188.129

 

192.168.188.129:3260,0iqn.2000-03.com.falconstor-ipstor.FalconStor-CDPVA.22b1279ae764-0

给客户端分配磁盘

 

当完成后会弹出是否分配磁盘的窗口一步一步选择就可以完成了

 

在客户端上输入

 

[root@localhostPackages]# iscsiadm -m node -Tiqn.2000-03.com.falconstor-ipstor.FalconStor-CDPVA.22b1279ae764-0192.168.188.129 -l

连接服务器

 

 

 

 

[root@localhost Packages]# fdisk -l
