Recently after a power outage one of our routers would not boot. It gave some errors about not being able to see the flash device.
I replaced the compact flash and ran tftpdnld -r
Once I was in the IOS, I used the format command and copied the IOS over. I rebooted the router and now I get this message
Readonly ROMMON initialized program load complete, entry point: 0x8000f000, size: 0xc940 open(): Open Error = -66 boot: cannot open "flash:" boot: cannot determine first executable file name on device "flash:" c2821 processor with 262144 Kbytes of main memory Main memory is configured to 64 bit mode with ECC enabled
I also tried tftpdnld to restore flash in rommon and I got this error after it completed
File reception completed. Validating checksum. Copying file c2800nm-spservicesk9-mz.151-4.M8.bin to flash. program load complete, entry point: 0x8000f000, size: 0xc940
Format: All system sectors written. OK... Formatting failure! Error code: -72
It is odd after replacing the flash I was able to boot to the IOS via tftp and format and copy the IOS with no issues, yet as soon as I reboot it, it says it can not open or access it from rommon
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
