centos连接磁盘柜
在centos 7上连接磁盘柜：
首先挂载
# mount /dev/cdrom /mnt/cdrom
mount: /dev/sr0 is write-protected,mounting read-only
安装iscsi包
# cd /mnt/cdrom/Packages/
# ls iscsi*
iscsi-initiator-utils-6.2.0.873-21.el7.x86_64.rpm
iscsi-initiator-utils-iscsiuio-6.2.0.873-21.el7.x86_64.rpm
# rpm -Uvhiscsi-initiator-utils-6.2.0.873-21.el7.x86_64.rpm
iscsi-initiator-utils-iscsiuio-6.2.0.873-21.el7.x86_64.rpm

安装成功，修改客户端名字
# more /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.wanyi:9e424108f4f
重启iscsi服务
# systemctl start iscsi.service
在console上添加一个客户端192.168.188.13：
选择不进行身份验证
设置客户机名称
为SELF客户机添加逻辑资源
在centos上查找Target
# iscsiadm -m discovery -t st -p192.168.188.128

操作成功之后，fdisk -l可查看到新增加了一块盘
