目的：配置Storwize存储iSCSI服务，并在window和Linux客户端连接
- 配合网口IP地址，最多可以配置4个
- 在iSCSI主机上设置iQN，以win2012为例
- 在v5000上用iqn创建主机
- 在v5000上LUN映射到ISCSI主机在v5000上LUN映射到ISCSI主机
- 在iSCSI主机上安装MPIO多路径软件，以win2012为例
- 配置MPIO
- 添加存储iSCSI连接
- 扫描iSCSI磁盘
linux下的iscsi initiate配置
配置iscsi
[root@client ~]# yum -y install iscsi-initiator-utils //安装客户端工具
查找自己的iqn名字
[root@localhost ~]# cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:848dcaf11552
- 在v5000上添加主机，并做1T的盘映射
- 在linux主机上启动iscsi服务，并扫描iscsi LUN
