H3C日常维护手册

H3C设备维护及故障处理指南1.前言在日常网络运维工作中，H3C（华三）设备是企业常用的一种网络设备。

为了确保网络的正常运行，提高网络设备的可靠性和稳定性，及时解决故障是非常重要的。

本指南将介绍H3C设备的维护和故障处理方法。

2.H3C设备维护2.1定期备份设备配置为了防止设备故障或配置丢失导致的网络中断，我们应定期备份设备的配置文件。

可以通过命令行界面或Web界面进行备份，并将文件保存在安全的地方，以备不时之需。

2.2定期升级设备固件H3C公司定期会发布新的设备固件版本，其中包括修复了一些已知的漏洞和故障，并提供了一些新的功能和性能改进。

因此，我们应该及时升级设备的固件，以确保设备的安全性和稳定性。

2.3监控设备的运行状态我们应该使用H3C设备提供的监控工具，如SNMP（Simple Network Management Protocol）或Syslog，来实时监控设备的运行状态。

这样可以及时发现设备的异常行为，并采取相应的措施，预防故障的发生。

3.H3C设备故障处理3.1故障排查与定位当发生网络故障时，应首先进行故障排查与定位。

可以通过以下步骤来进行排查：a.检查设备的各个接口是否正常工作，如链路是否正常、接口是否有异常状态等。

b.检查设备的日志信息，查找可能有关的错误或警告。

c. 对设备所在的网络进行测试，如Ping测试、Traceroute测试等，以确定故障范围和位置。

3.2故障解决方案根据排查与定位的结果a.如果是单一设备的故障，可能需要进行设备重启或问题接口的关闭/开启等操作。

b.如果是局部网络的故障，可能需要对网络中的其他设备进行检查，如交换机、路由器等。

c.如果是全局网络的故障，可能需要考虑网络中的整体拓扑结构，找出可能的单点故障，并进行相应的维修或切换。

3.3故障记录与总结在处理故障的过程中，应及时记录故障的相关信息，包括故障现象、解决过程和方法、影响范围等。

这样可以帮助我们更好地总结故障原因和处理方法，以便于以后的故障处理和维护工作。

H3C IX3000存储产品日常维护手册杭州华三通信技术有限公司All rights reserved版权所有侵权必究H3C IX3000存储产品日常维护手册尊敬的用户：感谢您使用H3C公司的IX3000存储产品，目前IX3000系列含IX3040、IX3080、IX3240和IX3620 四个产品。

存储业务系统正常、稳定地运行是我们共同的愿望，为了我们共同的目标，请您根据以下维护建议关注存储运行健康状态。

1、注意保持机房整洁，防尘防潮，保持机房温度处于正常范围之内。

2、不允许在线情况下随意插拔硬盘，对硬盘操作时需遵照《硬盘使用注意事项》进行。

3、请时常关注硬盘故障指示灯状态，如果硬盘黄色故障指示灯常亮，请立即联系H3C工程师处理。

4、请时常关注控制器故障指示灯状态，如果控制器故障指示灯常亮，请立即联系H3C工程师处理。

5、请时常关注DEU故障指示灯状态，如果DEU故障指示灯常亮，请立即联系H3C工程师处理。

6、请时常关注RAID状态，如果RAID处于降级运行状态，请立即联系H3C工程师处理。

7、请经常检查控制器状态，检查控制器电源指示灯，如果电源指示灯为常亮说明控器运行正常，如果电源指示灯闪烁，请立即联系H3C工程师处理。

8、请经常登录neocean neostor服务器，检查事件日志是否有warning和error两种级别的错误信息，如有请立即发给H3C工程师分析。

如下：9、如果要对存储进行关机，请严格按照正常关机流程处理或者联系代理商和H3C工程师支持。

10、如果机房出现异常断电情况，请及时恢复存储供电。

11、对设备硬件进行相关操作时应注意戴好防静电手腕。

1 查看系统异常时的处理方式通过执行display system-failure 命令，可查看系统异常时的处理方式。

<Sysname> display system-failureSystem failure handling method: reboot2 查看设备温度命令dis environment3.查看各插板的工作状态命令dis device实例如下图：4.查看风扇运行状态dis fan5.查看日志信息dis trapbuffer（查看系统告警）dis logbuffer （查看系统日志）详细解释入下图：5.显示当前生效的配（部分未生效的配信息不显示）dis cur命令：display current-configuration 描述：display current-configuration命令用来显示以太网交换机当前生效的配置参数。

对于某些正在生效的配置参数，如果与缺省工作参数相同，则不显示。

当用户完成一组配置之后，如果需要验证配置是否正确，则可以执行display current-configuration命令查看当前生效的参数。

对于某些参数，虽然用户已经配置，但如果这些参数对应的功能没有生效，系统不予显示（如单板不在位）；如果save 配置后，将保存当前能显示到的配置。

6.display saved-configuration命令：display saved-configuration描述：display saved-configuration命令用来显示以太网交换机的Flash中配置文件。

如果以太网交换机上电之后不能正常工作，可以执行display saved-configuration命令查看以太网交换机的启动配置。

十四章设备日常维护与常见故障处理
14.1日常维护建议
●路由器设备关系重大，应派受过培训的专人进行日常维护
●保持机房清洁干净，防尘防潮，防止鼠虫进入
●每天检查设备工作状态，指示灯，系统温度等
● 注意检查设备表面温度，检查风扇孔是否堵塞调整电缆和网线一定要慎重，
调整前一定要作标记，以防恢复时线序混乱，造成误接。

对设备硬件进行操作时应带防静电手腕。

● 不得轻易对设备进行复位、改动业务数据

dis mem 查看系统内存
dis logbuffer 查看系统日志
dis trapuffer 查看重大事件日志
14.3日常维护常用诊断工具
ping命令
tracert命令
display命令
reset命令
debug命令
14.4设备故障信息收集方法
display diagnostic-information
14.5故障处理流程与最快方法
