基于ipsan 的iscsi存储
192.168.3.128 target 端
192.168.3.129 intiator端
192.168.3.133 intiator端（winXP）
128上安装iscis target 软件
yum install scsi-target-utils
目录结构如下
[root@target ~]# rpm -qal scsi-target-utils

设置开机启动
chkconfig tgtd on
启动target
/etc/init.d/tgtd start
配置一个简单的ISCSI TARGet
tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2012-04.name.zhoutao:iscsi-disk1 #增加一个target 设备命令
[root@localhost ~]# tgtadm --lld iscsi --op show --mode target #查询target设备命令

允许192.168.3.129 这个主机可以存取target设备
tgtadm --lld iscsi --op bind --mode target --tid 1 --initiator-address 192.168.3.129
查看acl列表

将以上命令添加到开机启动
[root@localhost ~]# cat /etc/rc.local
tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2012-04.name.zhoutao:iscsi-disk1
tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/sdb1
tgtadm --lld iscsi --op bind --mode target --tid 1 --initiator-address 192.168.3.129
winxp 下initiator安装

在linux上配置initiaor端
yum安装iscsi-initiator-utils
[root@localhost ~]# rpm -qal iscsi-initiator-utils
/etc/iscsi
/etc/iscsi/iscsid.conf
/etc/logrotate.d/iscsiuiolog
/etc/rc.d/init.d/iscsi
/etc/rc.d/init.d/iscsid
/sbin/iscsi-iname
/sbin/iscsiadm
/sbin/iscsid
/sbin/iscsistart
/sbin/iscsiuio
/usr/include/fw_context.h
/usr/include/iscsi_list.h
/usr/include/libiscsi.h
/usr/lib64/libfwparam.a
/usr/lib64/libiscsi.so
/usr/lib64/libiscsi.so.0
。。。。。。。。。。。。。。。。。。。略
启动initiaor端
/etc/init.d/iscsi start
使用如下命令查看target主机划分的lun
[root@localhost ~]# iscsiadm -m discovery --type sendtargets -p 192.168.3.128
192.168.3.128:3260,1 iqn.2012-04.name.zhoutao:iscsi-disk1
执行一个target发现后会将查询记录写道以下目录下
[root@localhost ~]# cd /var/lib/iscsi/send_targets/
[root@localhost send_targets]# ls
192.168.3.128,3260
通过如下指令与iscsitaget端建立连接，
[root@localhost send_targets]# iscsiadm -m node -T iqn.2012-04.name.zhoutao:iscsi-disk1 -P 192.168.3.128 -l
Logging in to [iface: default, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260] (multiple)
Login to [iface: default, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260] successful.
如果有多个target 主机，可以使用如下命令一次性登录到所有的target主机上
[root@localhost send_targets]# iscsiadm -m node --loginall=all
Logging in to [iface: default, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260] (multiple)
Login to [iface: default, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260] successful.
断开连接
[root@localhost send_targets]# iscsiadm -m node -T iqn.2012-04.name.zhoutao:iscsi-disk1 -P 192.168.3.128 -u
Logging out of session [sid: 1, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260]
Logout of [sid: 1, target: iqn.2012-04.name.zhoutao:iscsi-disk1, portal: 192.168.3.128,3260] successful.
查看fdisk
[root@localhost ~]# fdisk -l
