HP-UX系統维护手册第一章、故障诊断一、硬件故障诊断1.电缆连接注意计算机及各外设之间连线接触良好,不要无故拔插电缆;如果发生计算机不能识别某个设备,有可能是电缆的接触问题。
2.硬件状态指示灯如果发现系统工作不正常,可以观察硬件状态指示灯的情况。
开机后系统将自动完成自测试,诊断及引导启动代码。
检测顺序大致为:高速缓存,中央处理器,总线,内存,I/O设备。
当检测到相关的硬件时,对应的显示灯会亮。
硬盘,软盘,磁带机及光盘驱动器自检时,能从前面板上看到相应的灯亮一下,表明系统已经识别到上述设备。
相反,如果某驱动器的自检灯没亮,很可能是该设备有问题。
另外,主机背后的SCSI接口卡及网络接口卡上的自检指示灯亮为正常状态。
否则,可能该接口卡有问题。
发现这种问题,请马上与HP联系,考虑更换备件。
3.错误代码每次开机后,系统都会自动进行硬件自检及初始化,假如系统出现硬件故障,一般都不能正常启动,并在液晶显示屏及控制台上相应的显示出错误代码及出错信息。
若屏幕上出现ERROR且液晶显示上出现FLT,表明有故障发生,应根据上述提示确定故障点。
绝大部分硬件错误都能在自检时暴露出来,在液晶显示及控制台的左下角都有四位错误代码,格式:FLT xxxx.分析这四位代码可以进一步检测出故障的情况。
如下表列出了K系列计算机的错误代码,相应的故障原因及解决方案。
二、软件故障诊断常用命令来查看系统状态。
1.# ioscan -fn列出各I/O卡及设备的所有相关信息:如逻辑单元号,硬件地址及设备文件名等。
2.# ps -ef列出正在运行的所有进程的各种信息:如进程号及进程名等。
3.# netstat -rn列出网卡状态及路由信息等。
4.# lanscan列出网卡状态及网络配置信息。
5.# bdf列出已加载的逻辑卷及其大小信息。
6.# mount列出已加载的逻辑卷及其加载位置。
7.# uname -a列出系统ID 号,OS版本及用户权限等信息。
