Continue? [confirm]Current DOS File System flash card in slot0: will be formatted into Low End File System flash card! Continue? [confirm]Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...erasedErase of slot0: complete然后尝试C3745#format slot0:Format operation may take a while. Continue? [confirm]Format operation will destroy all data in slot0:. Continue? [confirm]Enter volume ID (up to 64 chars)[default slot0]:Current Low End File System flash card in slot0 will be formatted into DOS File System flash card! Continue? [confirm]Format: Drive communication 1st Sector Write OK...Writing Monlib sectors........................................................................................................Monlib write complete....Format: All system sectors written. OK...Format: Total sectors in formatted partition: 1969458Format: Total bytes in formatted partition: 1008362496Format: Operation completed successfully.Format of slot0 complete这样格式化出来的CF卡不仅仅各个路由器可以访问PC机也可以访问了至此CF卡故障的原因搞清楚了。erase类似于低级格式化而format类似于高级格式化新的或者逻辑损坏的CF卡必须先erase过否则无论插到哪个非本机erase的路由器都会报*Apr 3 17:36:21.403: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from adifferent router or PC. A format in this router is required before an p_w_picpathcan be booted from this device必须先erase然后format这样copy文件就正常引导了而且最好不要一卡多机使用。说道这里45正常了两台25还是不正常。不管先解决tftp引导的问题昨天网络引导不成功一度认为是网络通信不好造成今天将两台25接到一个交换机上tftpserver也接着配置全部清空然后引导发现两台均不正常。无法从tftp获取IOS病轻的25在配置boot system slot0:c3725-adventerprisek9-mz.124-7.binboot system tftp c3725-adventerprisek9-mz.124-7.bin 10.1.1.100后第一次报CF无法读取第二次读网络的时候反而可以读取CF中的IOS而病重的那台索性就没有反应了。什么都不报就直接引导flash进入系统着实很奇怪。实在无奈只好拆机了小心翼翼的打开路由器先验证一下sdram是否通用验证可用这个部分另文叙述接着验证flash能否用非cisco的CF卡更换。下面讲的CF就是自己买的kingston的1G卡flash就是cisco原装的flash卡CF接入flash插槽无法开机flash接入slot0可以识别看来cisco还是认为自家兄弟亲shit再次拔插flash和CF好这下都可以用了而且CF可以从flash槽内启动前提是要先用这台25format一下然后用tftp装入IOS然后用这张卡引导。但是还是无法用原来的flash卡引导slot0内的CF只能讲CF换到flash槽上使用而且病重的25现在用原flash引导slot0的IOS都不报错了什么信息都没有直接进入flash的IOS极度的晕啊现在为了先解决眼前的问题赶快托人买了几张512的CF卡等着回来以后的消息。。 转载于:https://blog.51cto.com/netwalk/66256
