使用Lsiutil管理Dell SAS 6i/R
Dell的好多型號(如R410,R610)伺服器預設的RAID控制器都是SAS 6i/R ，對於這款控制器MegaCli是不能使用的。在命令列模式下想管理SAS 6i/R，需要使用Lsiutil這個工具。

Lsiutil下載地址：ftp://ftp.lsil.com/HostAdapterDrivers/linux/lsiutil/lsiutil.tar.gz

Lsiutil有兩種使用方法： 選單驅動的互動使用 和 命令列

不帶任何引數執行lsiutil，就會進入lsiutil的互動模式。在這個模式下，所有的操作都是通過文字選單來進行的，舉例如下：
