netapp linux iscsi 实现

环境：Redhat linux AS5，netapp simulator 7.3.4

操作步骤：

linux主机端

1.安装initiator。

[root@linux ~]# rpm –ivh iscsi-initiator-utils-6.2.0.742-0.5.el5.i386.rpm

安装完后会在/etc/iscsi下生成两个文件

initiatorname.iscsi和iscsid.conf

2.启动iscsi服务

有2种方法

A: service iscsi start/restart

B：cd /etc/init.d

./iscsi start

3.检查iscsi服务的状态

chkconfig --list|grep iscsi

确定运行后，记录下initiatorname

[root@Redhat ~]# cat /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.1994-05.com.redhat:23a52db21754

存储端

1.添加license协议

license add xxxxxxx

2.创建igroup

igroup create -i -t linux linuxas5 iqn.1994-05.com.redhat:23a52db21754

3.创建灵活卷

vol create vol1 aggr1 60m

4.创建lun

lun create -s 40m -t linux -o noreserve /vol/vol1/lun0

5.map lun

lun map /vol/vol1/lun0 linuxas5 0

6.check lun's status

if lun offline,you need to online : lun online /vol/vol1/lun0

再回到linux主机端

1.发现lun,获得target的inode。

#iscsiadm -m discovery -t st -p "存储ip"

iscsiadm -m discovery -t st -p 192.168.100.20

192.168.100.20:3260,2000 iqn.1992-08.com.netapp:sn.×××9383

2.挂载登陆lun

#iscsiadm -m node -T iqn.1992-08.com.netapp:sn.×××9383 -p 192.168.100.20 -l

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

logout lun(这个只是测试的时候可以用)

iscsiadm -m node -T iqn.1992-08.com.netapp:sn.×××9383 -p 192.168.100.20 -u

//

关于上面的操作，可以修改/etc/iscsi/iscsid.conf实现

vi /etc/iscsi/iscsid.conf

在最后加上：

DiscoveryAddress = 192.168.100.20  //target's Ip address//

SendAsyncText = yes //Initiator能从客户端接收到Vendor Specific的同步事件//

Continuous = yes //为了能指定全部依然打开的会话//

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

3.主机发现lun

fdisk -l

4.格式化lun

fdisk /dev/sdb

mkfs -t ext3 /dev/sdb1

5.设置挂载目录

mkdir /raid/sdb1

mount /dev/sdb1 /raid/sdb1

6.设置自动挂载位置，编辑/etc/fstab

#vi /etc/fstab

/dev/sdb1 /raid/sdb1 ext3 _netdev 0 0

7.查看容量

df -h

操作完毕
