本地端掛載遠(yuǎn)程服務(wù)器的磁盤或者分區(qū)當(dāng)成本地磁盤使用，目前有兩臺(tái)機(jī)器，分別是foundation(服務(wù)器端192.168.122.1/24) 和Desktop(終端192.168.122.2/24),先配置服務(wù)器端：以RHEL7為例，準(zhǔn)備一個(gè)分區(qū)/dev/sda5

#yum -y install targetcli            //安裝軟件
#systemctl enable target.service    //設(shè)置開機(jī)自啟
#systemctl start target.service        //啟動(dòng)服務(wù)
#targetcli                            //進(jìn)入命令行

進(jìn)入到/> cd backstores/block/目錄，創(chuàng)建后端區(qū)域磁盤,名字為back,這里使用的是分區(qū)/dev/sda5

/> cd backstores/block/
/> create back /dev/sda5
/backstores/block> cd ../../iscsi/
/iscsi> create iqn.2015-09.com.example:rhce  //創(chuàng)建本地鏈接名稱

進(jìn)入到tpg1目錄，創(chuàng)建acls,由于只有一個(gè)lun0，故這里可以不指定

/iscsi/iqn.20...hce/tpg1/acls>create iqn.2015-09.com.example.foundation:888

進(jìn)入到luns目錄，創(chuàng)建對(duì)應(yīng)關(guān)系

/iscsi/iqn.20...hce/tpg1/luns> create /backstores/block/back

指定端口

create ip_address=192.168.122.1 ip_port=3260

最后的目錄結(jié)構(gòu)為：

/> ls
o- / ................................................................................................... [...]
  o- backstores ........................................................................................ [...]
  | o- block ............................................................................ [Storage Objects: 1]
  | | o- back ...................................................... [/dev/sda5 (2.0GiB) write-thru activated]
  | o- fileio ........................................................................... [Storage Objects: 0]
  | o- pscsi ............................................................................ [Storage Objects: 0]

  |    | o- iqn.2015-09.com.example.foundation:888 ......................................... [Mapped LUNs: 1]
  |    |  o- mapped_lun0 ............................................................ [lun0 block/back (rw)]
  |    o- luns .................................................................................... [LUNs: 1]
  |    | o- lun0 ................................................................... [block/back (/dev/sda5)]
  |    o- portals .............................................................................. [Portals: 1]
  |      o- 192.168.122.1:3260 ......................................................................... [OK]
  o- loopback ................................................................................... [Targets: 0]

接下來配置防火墻

#firewall-cmd --permanent --add-port=3260/tcp --zone=public
#firewall-cmd --permanent --add-port=3260/udp --zone=public
#firewall-cmd --reload

現(xiàn)在將視線轉(zhuǎn)到desktop端

#yum install iscsi-*
#vim /etc/iscsi/initiatorname.iscsi  //將其中的默認(rèn)的名字改為服務(wù)器端中acls里設(shè)置的名字
#systemctl enable iscsi
#systemctl enable iscsid
#systemctl start iscsi
#systemctl start iscsid
#iscsiadm -m discovery -t st -p 192.168.122.1:3260    //發(fā)現(xiàn)設(shè)備
#iscsiadm --node -l                                    //登陸

登陸成功后fdisk -l即可看到新增的一塊磁盤，接下來可以對(duì)磁盤進(jìn)行格式化和掛載，即可正常使用
