SANBoot安裝系統

環境：

硬體：3台DELL R910無盤帶2G SD卡

1台DELL MD3820F存儲雙控

2台光纖交換機

軟體：windows server 2012 r2 with cu1

目标：R910伺服器的系統從存儲劃分的lun中sanboot引導啟動，并實作光纖雙鍊路高可用，搭建微軟伺服器虛拟化平台！

在此需要感謝我的同僚劉紹軍協助我完成SANboot的存儲調試！

存儲配置

劃分了3個存儲組利用每一個伺服器上的光纖卡綁定每一個存儲組，這樣每一個伺服器映射到的存儲組都是lun0，每一台伺服器上的系統都裝載在各自每一個存儲組的lun0中

伺服器配置

首先就是更改BIOS

修改BIOS和HAB配置時需要把2張HBA都插上光纖鍊路！

修改啟動順序

把網卡排2避免啟動的時候DHCP找PXE啟動

開啟虛拟化

接下來是修改HBA卡配置：

需要對2張HBA卡都進行同樣的設定：

紅色框住的都需要改成enable

開啟SAN BOOT啟動

下面這個延遲預設disable即可

放入CD光牒安裝windows時隻插一個HBA卡光纖鍊路，安裝系統時就可以看到多個路徑的磁盤：

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

如果磁盤01顯示脫機可能是HBA卡沒找到映射的存儲也或者是BIOS和HBA卡的配置不正确，還可以試下如下方法讓磁盤0聯機：

在安裝作業系統選擇安裝磁盤的界面按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.

最後安裝完作業系統以後2張HBA卡都需要連結2條光纖鍊路插好！接着安裝windows server 的多路徑功能以及安裝儲存設備自帶CD光牒的管理軟體（隻安裝主機功能）就可以解決多路徑磁盤問題，最後看到的是1個邏輯磁盤。
