双机热备服务器情况说明
原故障内容:
1.主服务器宕机后,备用服务器可接管数据但无法接管应用。

原因分析及解决步骤:
2.原因分析:
东软公司该软件的数据区域都是存在镜像磁盘Y的。

主服务器对于该软件更新的数据会实时更新在备服务器上,如果主服务器宕机,整个数据会切换到备用服务器上。

此时数据区域可以完全被备用服务器接管,但该软件的应用需要管理员手动运行,才可以正常。

该原因是软件在启动时需要调用Y盘的一些DLL文件才可以将一些必须的服务起来。

而在正常情况下主服务器向备用服务器实时进行数据同步时,备用服务器的Y盘是无法访问的,这时启动备用服务器上的该程序就无法访问。

这就造成主机切换后,备用服务器
上的该软件无法自动启动。

需要Y盘能访问后在将程序手动启动起来才可以使用。

解决步骤:
将该软件所需要起到的MYSQL_OA等五个服务,加入到HA软件的failover区域中去,这样如果发生故障切换后,备用服务器可先接管数据区域,然后自动将软件所需要的五个服务进行启动,就不需要管理员手动进行启动了。

Figure 1. Lenovo DSS-G Model G260Lenovo Distributed Storage Solution for IBM Spectrum Scale (DSS-G) (System x based)Product Guide (withdrawn product)Lenovo Distributed Storage Solution for IBM Spectrum Scale (DSS-G) is asoftware-defined storage (SDS) solution for dense scalable file and objectstorage suitable for high-performance and data-intensive environments.Enterprises or organizations running HPC, Big Data or cloud workloads willbenefit the most from the DSS-G implementation.DSS-G combines the performance of the Lenovo x3650 M5 servers, LenovoD1224 and D3284 storage enclosures, and industry leading IBM SpectrumScale software to offer a high performance, scalable building block approach tomodern storage needs.Lenovo DSS-G is delivered as a pre-integrated, easy-to-deploy rack-level solution that dramatically reduces time-to-value and total cost ofownership (TCO). All DSS-G base offerings, except for the DSS-G100, arebuilt on Lenovo System x3650 M5 servers with Intel Xeon E5-2600 v4 seriesprocessors, Lenovo Storage D1224 Drive Enclosures with high-performance2.5-inch SAS solid-state drives, and Lenovo Storage D3284 High-DensityDrive Enclosures with large capacity 3.5-inch NL SAS HDDs. The DSS-G100base offering uses the ThinkSystem SR650 as the server with up to eightNVMe drives and no storage enclosures.Combined with IBM Spectrum Scale (formerly IBM General Parallel FileSystem, GPFS), an industry leader in high-performance clustered file system,you have an ideal solution for the ultimate file and object storage solution forHPC and BigData.Did you know?The DSS-G solution gives you the choice of shipping fully integrated into theLenovo 1410 rack cabinet, or with the Lenovo Client Site Integration Kit, 7X74,which allows you to have Lenovo install the solution in a rack of your ownchoosing. In either case, the solution is tested, configured, and ready to beplugged in and turned on; it is designed to integrate into an existinginfrastructure effortlessly, to dramatically accelerate time to value and reduceinfrastructure maintenance costs.Lenovo DSS-G is licensed by the number of drives installed, rather than thenumber of processor cores or the number of connected clients, so there are noadded licenses for other servers or clients that mount and work with the file system.Lenovo provides a single point of entry for supporting the entire DSS-G solution, including the IBM Spectrum Scale software, for quicker problem determination and minimized downtime.Figure 2.

Lenovo SureHA G2(V2.0) Windows平台Share模式集群软
件安装配置文档
服务器二线支持
赵晓炜
2011、09
1、准备阶段
数据库装在本地,库文件装在存储盘上
1.1 网络
确保服务器内网和外网都可以相互ping通。

1.2、分区
共享磁盘只在一台主机上操作即可,其他主机查看即可。

共需要2个分区:
A、磁盘心跳分区-非必须,至少17M,建议20M,该分区为裸系统,无需格式化,盘符推荐使用X。

存储上划分
B、数据分区-容量根据实际情况划分,手动指定盘符,推荐使用Y,请快速格式化为NTFS 分区。

备注:由于Windows2003以上的操作系统不会自动分配盘符,所以,第二台主机分区手动分配的盘符要与第一台保持一致。

1.3 修改服务器主机名
请按照要求修改每个节点主机名称,修改后重启服务器使其生效。

1.4 暂时关闭防火墙
操作系统自带防火墙可能导致网路不通或者集群软件异常,建议暂时关闭。

实施完毕后再按需开启。

2、集群软件安装
每台服务器安装方法相同,均按照如下步骤操作。

2.1,打开安装文件路径,运行menu应用程序,请选择“SureHA Cluster for Windows”。

如下图:
2.2 接着选择“SureHA Cluster 2.0 for Windows”,如下图:
2.3 进入安装向导,选择“下一步”,如下图:
2.4 出现选择安装路径的提示,可根据实际情况修改,继续“下一步”,如下图:
2.5 提示可以安装程序了,直接点击“安装”,如下图:
2.6 出现安装进度条,如下图:
2.7 进入设置端口界面,建议保持默认,选择“下一步”,如下图:
2.8 进入共享磁盘的过滤设定步骤,选定连接共享磁盘的HBA卡,鼠标右键,选择“过滤”。

如下图:
2.9 已被过滤的分区前将以对勾标注,继续“下一步”。

如下图:
2.10 是否进行过滤设定,选择“是”,如下图:
2.11 提示设定已完成,点击“确定”,如下图:
完成安装。

如下图:
2.13 安装完毕,请选择“是,立即重新启动计算机。

”如下图:
3、集群软件的卸载
如果遇到相关问题需要卸载程序,请按此方法操作。

如果一切正常,则直接跳过此节,执行下一节集群软件配置。

3.1 使用共享磁盘时,卸载完成后访问限制会失效,因此请拔下与服务器连接的所有磁盘
线缆。

3.2 手动停止所有SureHA服务,进入Windows2008服务管理器,选择“配置”-“服务”,将所有SureHA 服务都手动停止。

如下图:
3.2 进入“控制面板”-“程序”-“程序和功能”,找到“SureHA Cluster Server”。

如下图:
3.3 选中程序,然后点击“卸载”,如下图:
3.4 询问是否进行卸载?选择“是”,如下图:
“是”,如下图:
3.6 卸载完毕,点击“完成”如下图:
3.7 卸载完毕后,选择重新启动计算机。

如下图:
4、集群软件配置
4.1 运行浏览器Cluster Manager,http://hostip:29003,可以使用带内和带外均可。

4.2运行Start builder,需要JA V A环境设置,光盘中带JA V A安装文件。

如果满足JA V A运行环境,打开页面后出现如下,三个选项,如果第一次设置,可以选择“启动集群生成向导”,
如果有已经生成的配置文件,可以选择“导入配置文件”。

4.3 添加集群名
选择“启动集群生成向导”,添加集群名称,选择合适的语言,如果是组合集群,如共享镜像型则需要添加管理IP地址,会自动增加MangagementGroup。

如果独立的镜像型或者共享
型,不需要添加管理IP地址。

如下图:
4.4增加服务器信息
集群会自动增加当前连接Webmanager的节点到集群软件中,所以,只需要添加其他节点即
可,可以添加服务器名或者IP地址,如下图:
主机名-建议进入服务器,使用hostname查看,请填入查看后的信息。

添加后可以看到已经被添加的节点信息,如下图:
除了私网外,建议同时添加公网IP作为备份。

默认只添加内核模式。

如下图:
4.6 NP(Network Partition网络分区)解决,这是防裂脑措施。

包括四种模式,一般情况下建议添加Ping方式。

如果有COM连线,可以选择COM口。

Disk模式仅仅支持共享模式。

多数模式支持2个节点以上的服务器使用。

共享模式下,请添加两个NP策略。

如下图:
4.7.1 添加组,点击“添加”,如下图:
中,如VMware ESX系列,则选择虚拟机。

命名组名称,如下图:
4.7.2 可启动服务器
添加服务器到组,将“可以在所有的服务器上进行失效切换”前对勾取消,将服务器节点,
从右侧天加到左侧。

如下图:
4.7.3 组属性设置,保持默认,继续“下一步”,如下图:
添加组资源
选择浮动IP资源和修改浮动IP名称,如下图:
将“遵循原有的依赖关系”前的对勾去掉,继续“下一步”,如下图:
将最终动作都按照下图选择。

成”即可。

选择资源类型和修改名称,如下图:
无依赖关系,请取消“遵循原有的依赖关系”前的对勾。

请按照要求选择最终动作,其他选项保持默认。

请点击“连接”按钮,如下图:
同样的操作,添加另一个节点的磁盘信息,添加完毕后,点击完成。

如下图:
至此,常规资源添加完毕,如下图:
4.8添加监视器
4.8.1添加浮动IP监视资源
在监视目标资源处,点击“参照”,选择fip1,如下图:
选择对浮动ip虚拟网卡的link状态的监视。

再活性化次数选择为0,点击“参照”,选定failover组。

4.8.2添加磁盘监视资源
磁盘TUR监视-不是所有的盘柜都支持TUR监视,光纤盘柜可以选择该模式。

如果遇到监
视资源异常的情况,请选择磁盘的其他监视资源。

如磁盘RW监视。

请保持默认,然后“下一步”。

如下图:
点击“参照”,选择sd1。

如下图:
点击“参照”,选择failover,如下图:
点击完成,可以查看到已经添加的所有监视资源,如下图:
4.9 应用配置文件
在线上传异常时可以选择其他节点进行上传。

根据提示确定,重启Webmanger。

如下图:
切换到“操作模式”,如下图:
从服务菜单,启动集群。

启动后信息如下:
5、验证集群
5.1 最简单方法-手动切换集群,如果可以成功,即可说明没有问题。

5.2、停止服务,如集群服务、数据库服务
换。

5.4、硬件操作,比如拔掉网线或者关闭或者重启计算机。
