CentOS7创建并挂载scsi共享磁盘

时间:2014-12-09 17:19 来源:linux.it.net.cn 作者:IT

实验设备：

用虚拟机虚拟两个 centos6.3 -64bit 系统，并配置好yum

ip设置：

scsi服务端：10.1.1.222

scsi客户端（挂载端）：10.1.1.1

实验开始：

1、在服务端安装软件并配置好共享的磁盘，首先在虚拟机中新加入一块硬盘，大小随意。（这里添加100G）

[root@localhost ~]# fdisk -l

Disk /dev/sda: 21.5 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x0005bb6c

Device Boot Start End Blocks Id System

/dev/sda1 * 1 26 204800 83 Linux

Partition 1 does not end on cylinder boundary.

/dev/sda2 26 281 2048000 82 Linux swap / Solaris

Partition 2 does not end on cylinder boundary.

/dev/sda3 281 2611 18717696 83 Linux

Disk /dev/sdb: 107.4 GB, 107374182400 bytes

255 heads, 63 sectors/track, 13054 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00077087

Device Boot Start End Blocks Id System

2、安装scsi服务端软件

yum install scsi-target-utils -y

共享磁盘（在配置文件中加入以下代码即可）

vim /etc/tgt/targets.conf

backing-store /dev/sdb

</target>

启动服务

service tgtd restart

关闭防火墙和selinux

3、在客户端安装客户端软件，并设置挂载

安装客户端软件

yum install iscsi-initiator-utils -y

查看是否有共享磁盘

iscsiadm --mode discoverydb --type sendtargets --portal 10.1.1.222 --discover

出现以下则表示有共享磁盘 10.1.1.222:3260,1 iqn.2008-09.com.example:server.target1

挂载磁盘

iscsiadm --mode node --targetname iqn.2008-09.com.example:server.target1 --portal 10.1.1.222:3260 --login

注意：中间2008-09这段是填写上面查询出来的那个磁盘名

成功挂载后有以下提示

[root@localhost ~]# iscsiadm --mode node --targetname iqn.2008-09.com.example:server.target1 --portal 10.1.1.222:3260 --login

Logging in to [iface: default, target: iqn.2008-09.com.example:server.target1, portal: 10.1.1.222,3260] (multiple)

查看以下挂载成功没有

[root@localhost ~]# fdisk -l

Disk /dev/sda: 21.5 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00036380

Device Boot Start End Blocks Id System

/dev/sda1 * 1 26 204800 83 Linux

Partition 1 does not end on cylinder boundary.

/dev/sda2 26 281 2048000 82 Linux swap / Solaris

Partition 2 does not end on cylinder boundary.

/dev/sda3 281 2611 18717696 83 Linux

Disk /dev/sdb: 107.4 GB, 107374182400 bytes

255 heads, 63 sectors/track, 13054 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00077087

Device Boot Start End Blocks Id System

成功挂载100G硬盘。

实验结束
