故障现象
朋友购买netapp fas3020C控制器，DS14MK2扩展柜，13个FC 146G硬盘；
连接开机，启动报如下错误：

按ctrl+c进入special menu，选择4a后系统panic，进入maintenance mode，sysconfig看不到磁盘；
将盘柜连接到正常控制器，sysconfig -d和sysconfig -v可以看到磁盘，

问题分析
盘阵将FC/SAS盘格式化为520字节/扇区（SATA盘格式为512字节/扇区），现在扇区大小为512字节，所以盘阵控制器不能使用；估计该磁盘扩展柜被主机格式化使用过；所以现在的问题是，如何将这些磁盘格式化为520字节/扇区？
磁盘低格520字节/扇区
- 工具搜索
累
- 下载安装
http://sg./sg/sg3_utils.html
我下载的是1.29版本，下面链接有安装步骤
http://www./blfs/view/svn/general/sg3_utils.html
./configure --prefix=/usr && make make install
- 格式化
扫盘：将扩展柜用与主机fc卡连接，系统扫到13块磁盘，如下：

知识点问题
- BCS/ZCS:磁盘阵列为保证数据存储高可考性，提供两种扇区数据校验，一是Block校验，520个字节/扇区，512+8，8个字节校验信息对512个字节进行校验；一是Zone校验，（8+1）*512，第9个扇区存放校验信息对前面8个扇区数据进行校验；写时连同校验信息一同写入，读时会对读出的数据进行校验比对，如果不一致，会进行RAID级条带恢复；
- SCSI
- SFS/HPFS文件系统
IBM TotalStorage SAN文件系统(SAN File System)，IBM SFS将多个独立的文件系统抽象为一个单一的共享文件系统，从而解决了传统SAN架构中的文件和数据管理问题；
高性能文件系统 （High Performance File System ，HPFS），HPFS是Microsoft的LAN Manager中的文件系统，同时也是IBM的LAN Server和OS/2产品。在OS/2中，它就是HPFS，但是在LAN Manager和LAN Server产品中，它是HPFS386，这是HPFS的改进版本。HPFS提供了DOS文件系统中的文件分配表(FAT)所没有的长文件名和性能增强特性。另外，HPSF还能访问较大的硬盘驱动器，提供更多的组织特性并改善了文件系统的安全特性。HPFS386增加了对HPFS文件系统的32位访问，另外还增加了容错和安全性功能
