硬件
主板：intel_7230-ah（入门级）服务器主板
#lspci
00:1f.2 RAID bus controller: Intel Corporation 82801GR/GH (ICH7 Family) Serial ATA Storage Controller RAID (rev 01)
官方提供的驱动只有redhat enterprise 4.0的驱动

仔细研究发现和intel——s3000主板属于同一系列，资讯intel客服承认两者除支持CPU型号不同外都相同。

故此 发现s3000可以下到redhat enterprise 5.0的驱动
软件
CentOS5.0

所以寻求如何来驱动raid。
我这服务器已经有系统，所以在系统上又多加了2块160G硬盘，做RAID0，BIOS自检时候，显示RAID0制作成功。
但是系统无法识别。

重启后依然不行，磁盘还是两块，而不是raid0。

jinl

lsmod,查看你的驱动模块是否加载
dmesg 看看是否有错误
