CentOS 5.2+Raid 0+LVM+ISCSI配置详解(4)

新增 target device 命令如下：
 
#tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2008-12.cn.lanexpert:iscsi-data1
 
执行后，可以利用以下命令查看 target device:
# tgtadm --lld iscsi --op show  --mode target
Target 1: iqn.2008-12. cn.lanexpert:iscsi-data1
    System information:
        Driver: iscsi

3、 将 target server 新建的 LV1 （ /dev/LVM1/data1 ）加入 target device
#tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/LVM1/data1
将逻辑卷加入 target device 后，利用下列命令查看 target device 的信息：
# tgtadm --lld iscsi --op show  --mode target
Target 1: iqn.2008-12. cn.lanexpert:iscsi-data1
    System information:
        Driver: iscsi

4、 允许 initiator 主机 node1(192.168.3.18) 可以存取此 target device
#tgtadm --lld iscsi --op bind --mode target --tid 1 -I 192.168.3.18
 
将逻辑卷加入 target device 后，利用下面的命令查看 target device 的信息：
# tgtadm --lld iscsi --op show  --mode target
Target 1: iqn.2008-12.local.superlgroup.xt:iscsi-data1
