如何创建LIO Target

这里介绍如何使用targetcli命令进行lio target的配置

1.进入targetcli名ing行
# targetcli

2.创建底层存储

/> cd backstores/iblock

 

/backstores/iblock> ls

o- iblock ....................................................................................................... [0 Storage Object]

 

/backstores/iblock> create name=iscsi0 dev=/dev/vmdata/iscsi0

Generating a wwn serial.

Created iblock storage object iscsi0 using /dev/vmdata/iscsi0.

Entering new node /backstores/iblock/iscsi0

 

/backstores/iblock/iscsi0> ls

o- iscsi0 ......................................................................................... [/dev/vmdata/iscsi0 deactivated]

××这里使用块设备来创建底层设备，也可以使用文件来创建，如果使用文件，则进入backstores/fileio目录创建。使用命令：
[root@atlas-pc ~]# dd if=/dev/zero of=/dev/vmdata/iscsi0 bs=4M count=256

# targetcli

>cd backstores/fileio

/backstores/fileio>  create name=iscsi0 file_or_dev=/dev/vmdata/iscsi0 size=1G

3.创建target

/backstores/iblock/iscsi0> cd /iscsi

 

/iscsi> create

Created target iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793.

Selected TPG Tag 1.

Successfully created TPG 1.

Entering new node /iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1

 

/iscsi/iqn.20...66a0793/tpgt1> ls

o- tpgt1 ................................................................................................................. [enabled]

  o- acls .................................................................................................................. [0 ACL]

  o- luns .................................................................................................................. [0 LUN]

  o- portals ............................................................................................................ [0 Portal]

4.创建lun

/iscsi/iqn.20...66a0793/tpgt1> cd luns

 

/iscsi/iqn.20...93/tpgt1/luns> create /backstores/iblock/iscsi0

Selected LUN 0.

Successfully created LUN 0.

Entering new node /iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1/luns/lun0

 

/iscsi/iqn.20...gt1/luns/lun0> ls

o- lun0 ....................................................................................... [iblock/iscsi0 (/dev/vmdata/iscsi0)]

5.创建portal

/iscsi/iqn.20...66a0793/tpgt1> cd portals

/iscsi/iqn.20...tpgt1/portals> ls

o- portals .............................................................................................................. [0 Portal]

 

/iscsi/iqn.20...tpgt1/portals> create 192.168.122.1 3260

Successfully created network portal 192.168.122.1:3260.

Entering new node /iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1/portals/192.168.122.1:3260

 

/iscsi/iqn.20...68.122.1:3260> cd ..

/iscsi/iqn.20...tpgt1/portals> create 192.168.122.1 3261

Successfully created network portal 192.168.122.1:3261.

Entering new node /iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1/portals/192.168.122.1:32616.创建acls

6.添加访问许可(acls)

/iscsi/iqn.20...66a0793/tpgt1> cd acls

 

/iscsi/iqn.20...93/tpgt1/acls> create iqn.1993-08.org.debian:01:50d4b3301a24

Successfully created Node ACL for iqn.1993-08.org.debian:01:50d4b3301a24

Created mapped LUN 0.

Entering new node /iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1/acls/iqn.1993-08.org.debian:01:50d4b3301a24

/iscsi/iqn.20...:50d4b3301a24> ls

o- iqn.1993-08.org.debian:01:50d4b3301a24 ........................................................................... [1 Mapped LUN]

  o- mapped_lun0 ....................................................................................................... [lun0 (rw)]

**create后的参数为initiator的名字，可以在客户机的/etc/iscsi/initiatorname.iscsi文件中找到

7.设置授权属性

这里设置为可以无密码访问

/> cd iscsi/iqn.2003-01.org.linux-iscsi.l99.x8664:sn.936bc66a0793/tpgt1/

/iscsi/iqn.20...66a0793/tpgt1> set attribute authentication=0

Parameter authentication is now '0'.

/iscsi/iqn.20...66a0793/tpgt1>

8.保存配置

/iscsi> cd /

 

/> saveconfig
