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
