核心CISCO7609故障处理
核心CISCO7609故障处理 |
用户打来电话说下面各个学校都不能上网了！这个事情有点大，远程登录用户的安全网关，发现安全网关可以登录，运行正常。但是安全网关与核心7609相连的接口是无连接状态，看来问题应该是出在7609上，后来用户反映下面各学校的交换机上连接口指示类都不亮，进一步确定了问题的位置——CISCO7609 匆忙赶到用户现场，发现7609引擎板上的灯全部都亮起了红色，这可不是一个好现象。据用户反映该机房在近两天停电了两次，故障是发生在第二次停电后重起。 通过console口接入发现7609进入到了如下模式： rommon 1 > 虽然进入到了rommon模式，但最起码能够进来，还是不错的！ 通过dir命令查看，发现系统文件仍在，如下是dir查看的结果 rommon 5 > dir bootdisk: Initializing ATA monitor library... Directory of bootdisk: 2 160648132 -rw- c7600rsp72043-ipservices-mz.151-3.S4.bin 19613 33554432 -rw- sea_log.dat 23709 461976 -rw- crashinfo_20141013-160619-BJ 发现系统文件后，我按照常规作法，对7609进行了手动引导。 rommon 6 > boot bootdisk:c7600rsp72043-ipservices-mz.151-3.S4.bin 但是引导的结果并不尽如人意！！！，以下是手动引导过程： Initializing ATA monitor library...

后面检测板卡的过程我就不贴出来了。 到最后系统终于启动正常，为了进一步测试我把电源断开，再重新加电，系统依然正常启动！至此，故障解决了！
胡思乱想：我在想是不是由于用户那里的两次断电，加电过程，由于电压、电流高低不同，导致瞬间系统的寄存器值发生改变，以导致了后来的故障！ 有兴趣朋友可以了解更多java教程 http://java.itcast.cn/java/video.shtml |
