TCI0121 Hitachi TagmaStore? AMS/WMS安装与配置客户订制课程 故障诊断与维护 V1.1 本章目标 完成本章后,学员能够: 掌握故障诊断的基本步骤 掌握如何收集Trace, dump 如何更换有故障部件 Copy back less的应用 本章主题 磁盘阵列指示灯的状态及开关的功能 通过WEB监控磁盘阵列 基本故障诊断步骤 动态热备盘的Copy back less 功能 面板指示灯及开关位置 面板指示灯的含义与开关功能 磁盘状态指示灯及全局指示灯 硬盘指示灯的含义 Web界面的连接 控制器内置Web服务器 http://xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx代表控制器的IP Web界面功能区 磁盘状态 其他部件状态 基本流程 故障诊断流程 结合现场故障显示灯,用WEB方式访问分析故障 确认部件状态 查看 information messages 并确认部件显示灯 LEDs 找到故障部件?报告故障 实施恢复操作 (通常是更换部件) 确认故障已恢复 用WEB方式访问分析故障 第 2步: Confirm Component Status 用WEB方式访问分析故障 步骤3: 读 Information Messages 例如 - HDU 故障 (Unit-0, HDU-4) 故障诊断的基本步骤 步骤5: (续) Example - HDU failure 故障诊断的基本步骤 步骤 6: 实施故障的恢复 （请注意带防静电手环） Example - HDU failure 故障诊断的基本步骤 步骤 7: 确认故障已恢复 Example - HDU failure (Unit-0, HDU-4) is recovered 故障诊断的基本步骤 步骤7: (续) Example - HDU failure Subsystem is in ready state and all HDUs are in normal state 故障诊断的基本步骤 步骤 7: (续) Example - HDU failure (Unit-0, HDU-4) is recovered HDS AMS/WMS正常开关机顺序 HDS AMS/WMS正常开关机顺序 热备盘的Copy back less 功能 热备盘的Copy back less 功能 本章回顾 为何AMS/WMS 的maintenance port 有2个不同的IP? 基本故障诊断的步骤是什么? 谢谢! It can be 2 different values so that if both the maintenance and the user port are connecting to the same network, IP address duplication is prevented. However, an IP address conflict can easily occur when connecting the maintenance ports of 2 or more DF700s to a common network. The factory default values can be configured, but the procedure is the same as for any other change; there is no quick way. SNMP can be used for configuring a device, but it is not used on the DF700 for this purpose. SNMP is used for reporting status and error information only. The protocol, as provided and used by Storage Navigator Modular is used for configuration. *? 2005 Hitachi Data Systems *? 2005 Hitachi Data Systems HDS Academy 指示灯状态 *控制器模块 *扩展模块 图1-1 AMS200/AMS500/WMS100系统指示灯及开关位置 按一下可以停止磁盘系统的蜂鸣报警。若磁盘发生严重的硬件错误，蜂鸣报警有可能不能被停止。 BUZZER OFF SW OFF: Turns off the power Main switch off
