//检查配置是否正确
//以上调整在洛阳通信公司成功通过
//相信在其他型号的控制器上也可以成功,请大家查阅一下即可,应该没有问题
//不过,一定要用户做好数据备份

| [quote:40a8c022b8="netkey"]已经改名字加精华了[/quote:40a8c022b8]呵呵！其实上面的操作就是对DEC的磁盘柜操作，只要大家看一下DEC提供的安装文档就可以了！没有什么实质性的意义！
但是，上面所指出的性能问题，要大家引起足够的重视，一个RAID的中硬盘最好是分布在几个不同的通道上，可以提高读写性能。 大家可以找我多交流存储技术！ |

| 同意楼上，我还以为不用重新导数据的做法哪。这不重新配置吗 |
| 我爱小笼包 回复于：2003-05-21 14:08:14 |
| 1. 这个就是不用重新导数据呀，上面说要备份好数据只是以防万一。因为重建后的raid组没有用init进行初始化，如初始化了就完了。
2. 做完后，重新启动主机，就可以像原来一样用，不用改动任何东东了。 3. 另外下面每个加disk,storageset等都可以起不同的名字，只要unit不变就行了。不过请注意如果有partition的话要更加小心千万不能错。 4. 此方法也可以用于把所有的盘换到另一个盘柜上去。 |
