SANBoot安装系统

环境：

硬件：3台DELL R910无盘带2G SD卡

1台DELL MD3820F存储双控

2台光纤交换机

软件：windows server 2012 r2 with cu1

目标：R910服务器的系统从存储划分的lun中sanboot引导启动，并实现光纤双链路高可用，搭建微软服务器虚拟化平台！

在此需要感谢我的同事刘绍军协助我完成SANboot的存储调试！

存储配置

划分了3个存储组利用每一个服务器上的光纤卡绑定每一个存储组，这样每一个服务器映射到的存储组都是lun0，每一台服务器上的系统都装载在各自每一个存储组的lun0中

服务器配置

首先就是更改BIOS

修改BIOS和HAB配置时需要把2张HBA都插上光纤链路！

修改启动顺序

把网卡排2避免启动的时候DHCP找PXE启动

开启虚拟化

接下来是修改HBA卡配置：

需要对2张HBA卡都进行同样的设置：

红色框住的都需要改成enable

开启SAN BOOT启动

下面这个延迟默认disable即可

放入光盘安装windows时只插一个HBA卡光纤链路，安装系统时就可以看到多个路径的磁盘：

<a href="http://rdsrv.blog.51cto.com/attachment/201407/31/2996778_1406779772QFuq.png" target="_blank"></a>

如果磁盘01显示脱机可能是HBA卡没找到映射的存储也或者是BIOS和HBA卡的配置不正确，还可以试下如下方法让磁盘0联机：

在安装操作系统选择安装磁盘的界面按shift+f10：

Diskpart

Diskpart&gt;List disk

Diskpart&gt;select disk 0

Disk 0 is now the selected disk.

DISKPART&gt; ATTRIBUTES DISK CLEAR READONLY

Disk attributes cleared successfully.

DISKPART&gt; attributes disk

Current Read-only State : No

Read-only : No

Boot Disk : No

Pagefile Disk : No

Hibernation File Disk : No

Crashdump Disk : No

Clustered Disk : No

DISKPART&gt; ONLINE DISK

DiskPart successfully onlined the selected disk.

最后安装完操作系统以后2张HBA卡都需要链接2条光纤链路插好！接着安装windows server 的多路径功能以及安装存储设备自带光盘的管理软件（只安装主机功能）就可以解决多路径磁盘问题，最后看到的是1个逻辑磁盘。
