RAID技术使用中存在的问题及对策

独立磁盘阵列技术虽然比较成熟，在小型机，服务器甚至微型计算机上都得到了广泛的应用。但是在具体的使用过程中，对使用者而言，由于普及程度不够，实践应用经验的欠缺，面对实际工作中各种不同的情况，例如：磁盘阵列崩溃后的阵列信息的不同修复方法；混用磁盘阵列级别崩溃后逻辑磁盘中原始数据的保持；什么情况下需要降低磁盘阵列卡固件BIOS的程序板本，具体如何操作；在做镜像时死机是因为什么原因造成的且如何解决等具体情况，即使对专业工程技术人员，也常感到无从下手。作者通过对长期实践工作中的总结，归纳了4个较有典型意义的案例解决方案。目的在于读者遇到同类问题时，能够节省时间，少走弯路，以加快磁盘阵列系统的修复或重建进程。

Solutions to the Problems Lies in Application of RAID Technology

The RAID technology is relatively mature now and applied widely in serverand even micro computer, but due to lack of experience in its application,even professional engineers feel at loss about the problems lisuchas, disk array information recovery when RAID corrupt, original data retaining when RAID corrupt for commixing disk's levels, when and how to resume lower version of BIOS of the disk array, why system down at time of mirror operation and how to solve it. The writer summaries solutions for 4 typical cases based on his experience in relevant work, to provide reference for readers that have similar problems, in the hope of helping them recovery the disk array fast.
