添加前的准备工作： 1.对DS4000或DS5000系统中的数据进行完全备份 2.确认备份已经成功
3.确认当前的系统的控制器微码，NVSRAM和ESM的微码（参考11） 注意：在升级微码前，请查看微码中的README文件，确认微码的升级步骤
4.确认硬盘微码为最新版本 5.确认当前DS4000或DS5000中的硬盘处于最佳(optimal)状态
6.如果连接了扩展柜，通过Storage Manager的Read_Link_Status功能和Major Event
Log(MEL)功能，确认扩展柜环路(drive loop)处于最佳(optimal)状态 7.查看并解决Major Event
Log(MEL)中的错误问题 8.保存当前DS4000或DS5000的配置信息
9.如果混插FC和SATA硬盘，请购买并激活混插许可
10.添加硬盘前，请检查硬盘与当前DS4000或DS5000的系统的兼容性（参考11） 11.更多详细工作请参考IBM System

DS4000系列存储Cache电池保护时间标称为72小时。由于DS4000的Cache是一种易失性存储介质，需要持续供电才能存储数据，一旦失去供电Cache中的数据将丢失。如果DS4000打开Cache功能（尤其是write
cache），应用端数据写到Cache中就会返回写成功，但此时数据并没有写到磁盘中（一般需要一定条件触发从cache写到磁盘，如：10秒以后或Cache容量达到80%等，该过程称作flush），若意外掉电，电池就会保护Cache中的数据，该电池为充电电池，可以保护72小时。

对于Stoarage Manager 10，定义热备盘有两种方法：自动分配(Automatic assign)和手工分配(Manual
assign)。 注意： 1)从Storage Manager 10.10开始，全局热备盘不再有数量限制。
2)热备盘的容量要大于或等于存储子系统中其他磁盘的容量 3)在包含大量磁盘的配置中，由于重建时间较长，有必要定义多个热备盘
4)如果DS4000中包含FC和SATA硬盘，需要考虑定义FC和SATA作为热备盘，因为FC硬盘不能保护SATA盘创建的Raid组，反之亦然。

使用ServerGuide 设置和安装CD 时，您不需要安装软盘。可以使用CD 配置任何支持的IBM
服务器型号。安装程序提供了安装服务器型号所需要的任务列表。在装有ServeRAID 适配器或具有RAID 能力的集成SCSI
控制器的服务器上，您可以运行SCSIRAID 配置程序来创建逻辑驱动器。 注：ServerGuide 程序的特征和功能可能随版本的不同而略有不同。要了解您现有版本的更多信息，请启动ServerGuide 设置和安装CD
并查看联机概述。并非所有的服务器型号都支持所有特点。ServerGuide 程序需要一台具有已启用的可启动（可引导）CD-ROM 驱动器的、受支持的IBM
服务器。除ServerGuide 设置和安装CD 外，您还必须准备好操作系统CD 以安装操作系统。

RAID卡就是用来实现RAID功能的板卡，通常是由I/O处理器、硬盘控制器、硬盘连接器和缓存等一系列零组件构成的。不同的RAID卡支持的RAID功能不同。支持RAlD0、RAID1、RAID3、RAID4、RAID5、RAID10不等。RAID卡可以让很多磁盘驱动器同时传输数据，而这些磁盘驱动器在逻辑上又是一个磁盘驱动器，所以使用RAID可以达到单个的磁盘驱动器几倍、几十倍甚至上百倍的速率。
RAID卡损坏不同于服务器别的部件损坏，由于它与硬盘都和服务器数据息息相关，所以一旦RIAD卡损坏，就就有可能造成服务器数据的丢失，特别是某些RAID卡，在其中存有部分RAID信息，一旦损坏，就算更换一块新的RAID卡，服务器的数据也无法正常使用。我中心的RAID卡维修则无此顾虑，公司自主研发的磁盘阵列恢复软件可以通过一系列的职能算法，恢复出存放在RAID卡中的RAID信息，保证在RAID卡维修或更换后服务器中的数据能够正常使用
