LSI的硬RAID卡，可以通过MegaCli以命令行方式管理，具体的可以google下，megacli的安装、命令格式等。还有一种方式就是使用MegaRaid Storage Manager图形界面管理，这方面的文章不多，自己安装试用了下，具体记录如下：
1、Server的操作系统为CentOS5.4，这里所指的Server即安装RAID卡的那台机器。
[root@chunk1 ~]# cat /etc/redhat-release
CentOS release 5.4 (Final)
2、可以简单地查看RAID卡的型号，详细信息利用MegaCli可以更清楚的看到
[root@chunk1 ~]# dmesg |grep -i raid
scsi0 : LSI SAS based MegaRAID driver
Vendor: LSI Model: MegaRAID 8888ELP Rev: 1.20
Vendor: LSI Model: MegaRAID 8888ELP Rev: 1.20
device-mapper: dm-raid45: initialized v0.2594l
md: Autodetecting RAID arrays.
3、下载“MSM_linux_installer-8.00-05.tar.gz”软件，解压，执行./install.sh安装，同意license，为了方便，选择“1”完全安装。

5、到这里Server端就安装结束了。
6、接下来安装管理软件，即“MegaRaid Storage Manager.exe”，安装很简单，同样的，在选择安装模式时，选择“complete”就好。
7、之后就可以输入Server端的IP地址，输入用户名/密码，login
8、看到统计信息，包括磁盘数量，磁盘组数量，使用容量等等
9、看到各个磁盘的状态
10、可以看到详细的逻辑磁盘、磁盘组的状态
11、另外还可以针对磁盘做设置，如设置全局热备盘，单独RAID组中的热备盘，当然这个要看你的存储设备支不支持全局热备了。
12、在这里可以创建磁盘组等等。
这比用megacli一打长串命令人性化多咯！对那些经常配置RAID组，监控RAID状态的人来说，MegaRaid是个比较好的工具！
