噶米IBMX3650服务器+DS3400SAS磁盘柜双机热备方案

1、I BM X3650 服务器+DS3400 SAS磁盘柜双机热备方案双机热备软件能对计算机的操作系统、网络系统和数据库及时进行检测，当其中任何一个系统岀现问题时双机软件能自动运行到备用服务器上，让备用服务器接管主机的工作，达到让计算机永不停机，数据永不丢失。实现目标：a）实现自动备份：在无需人工干预的情况下实现自动启动备份作业；b）灾难恢复：对不可预期的人为或自然灾难实现灾难恢复能力；C）业务不中断：支持对数据库24*7访问；d）集中管理：分布在整个网络的数据集中管理存储；e）易用性：这主要体现在图形用户界面和无人值守的操作。f） 适度冗余：总体存储容量保持30%的冗余，以适应今后可能的网络数

2、据扩充。g）扩展性能：有良好的扩展性，对新增的应用数据的备份容易扩展IBM双机热备方案所需软硬件清单如下:设备名称说明数量服务器IBM X36502磁盘柜IBM DS34001连接线SAS连接线1服务器配卡SAS HBA 卡2模块双机模块（子卡）一块1HA软件ROSE HA OR LIFEKEEPER1芯跳线超6类网络心跳线1DS3400/DS3400 安装技巧DS3000系列均需要在自身上安装不少于4个硬盘。建议先装上硬盘再上电开机。DS3000系列提供与DS4000系列类似的带内和带外两种管理方法，带外管理的默认IP地址也与DS4000 一样，控制器 A 为 01

3、, 控制器 B 为 02。本人比较喜欢采用带外管理，将本本网卡设至192.168.128 网段后，可以ping通即可。管理口长时间未起用时需要若干分钟的时候等待管理接口工作。在本本上安装 DS3000 Storage Manager （随机附带），注意该SM与DS4000 上的Storage Manager为不同程序，不可替换使用。甚至不能在一台机器上共存。打开Storage Manager后，首先需要发现设备，可以ping通控制器后，发现工作会非常容易。双击发现的设备就可以进入该设备的管理界面，学名叫Subsystem Management 。Subsystem M

4、anagement 分为 5 个大项，Summary ， Configure ， Modify ， Tools ， Support 。常规的操作这里不再详述，如果你装过DS4000 产品，应该对配置方法不会感到陌生。当然Storage Manager里只提供一些常规功能，在遇到问题的时候，比如需要重置手动清零时在该程序里无法完成的，所以与 DS4000 产品一样，提供了 Script的方式，运行Script有两种方法。方法一：在DS3000 Storage Manager 的Enterprise Manager界面里右击单击所找到的设备，选择ExecuteScript。方法二，在里找到smcl

5、i.exe 程序，使用 smcliip-address -c commandline;的方式执行。DS3400和DS3400都会有单控和双控两种机型。如果您购买的是单控的型号，而在安装时发现系统有 类似找不到第二个控制器的电池，冗余路径丢失的错误，那是由于未将系统设置成单控工作模式所引起的， 遇到这种方法，可以在Execute Script窗口下键入：set storageSubsystem redundancyMode=simplex;然后，选择Tools菜单下的Execute only来执行。如果遇到需要重置系统设置的需要也可以在同样的窗口下执行：clear storageSubsyste

6、m configuration / eventlog等。当然如果大家有兴趣也可以进一步借助该系统了解一下更多的命令功能，相信会对进一步masting 该设备有更好的帮助。1.确认与DS3400的连接正常：2.准备：连接管理站（笔记本）到 DS3400A控制器的管理口，并在管理站安装storage manage。例如：服务器端安装 windows2003打SP1补丁及各种设备驱动具体操作如下DS34003.打开 Storage Manager 自动所搜 storage subsystem rename盘柜，选择配置 DS3400:-：gl6M-39GAPCB-OUt-pf-Band Storag
