             iscsi target配置for CentOS6

1、共享源scsi-target安装配置

1.1 安装iscsi-target

  yum install scsi-target-utils -y

1.2 把/dev/sdb共享出去

<target iqn.2008-09.localdomain.localhost:sdb>

    backing-store /dev/sdb      # Becomes LUN 1

    write-cache off

</target>

 

1.2 启动iscsi target服务

 chkconfig tgtd on

 /etc/tgtd restart

1.3 查看共享是否成功

#tgtadm --mode target --op show 

Target 1: iqn.2008-09.localdomain.localhost:sdb

2、iscsi客户端

2.1 iscsi-initiator-utils安装

 yum -y install iscsi-initiator-utils

 

2.2 发现共享源的设备

#iscsiadm -m discovery -t sendtargets -p 192.168.8.101  #共享源服务器为192.168.8.101 

192.168.8.101:3260,1 iqn.2008-09.localdomain.localhost:sdb

 

2.3 查看分区

 cat /proc/partitions 

 

2.4 分区管理

#fdisk -l

Disk /dev/sdc: 1073 MB, 1073741824 bytes

34 heads, 61 sectors/track, 1011 cylinders

Units = cylinders of 2074 * 512 = 1061888 bytes

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

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

Disk identifier: 0x00000000

#共享过来的设备盘符在本地盘符基础上自增。

 

2.5客户端自启动

chkconfig iscsid on

chkconfig iscsi on
