ASR903 boot IOS from USB in rommon mode

[adamcarter778373960]

Hello, 

I've been given an ASR903 to configure for use on a testbed. However when I first booted it up, it says:

no valid BOOT image found

Final autoboot attempt from default boot device....

Warning: filesystem is not clean 

Warning: filesystem is not clean

Located tracelogs.332

Image size 0 inode num 12, bks cnt 0 blk size 8*512

Boot image size = 1139 (0x473) bytes

Unknown image structure

boot: cannot determine first file name on device "bootflash:/" 

autoboot: boot failed, restarting

Then the system starts up in ROMmon mode. I did some googling and tried to boot off of a usb which is the following: 

rommon 14 > boot usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin

Unknown image structure

boot: error executing "boot usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin"

I've been googling different ways to upload the IOS onto the device all day and I'm at my wit's end. Any help is much appreciated.

Also I obtained the .bin file from another testbed ASR903 in a building that I don't have 24/7 access to.

Thanks,

Adam

Can you post the complete output to the ROMMON command "dir bootflash:"?

While in ROMMON, try this: 

copy usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin bootflash: 

 After the copying has been completed, then do this: 

boot bootflash:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin

[adamcarter778373960]

It comes up saying the copy command is not found

rommon 4 > copy usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin bootflash:


monitor: command "copy" not found


rommon 5 >

[Leo Laohoo]

How about this: 

emergency-install usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin

[adamcarter778373960]

Same again :/

rommon 3 > emergency-install usb0:asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin


monitor: command "emergency-install" not found

In ROMMON, post the output to the command "?".

This looks like the router was loaded with SD-WAN firmware.
Kindly post the complete output to the command "set".

[adamcarter778373960]

I booted up the router to try input the set command but now it is stuck on this screen. This output is straight from powering on.

[adamcarter778373960]

I have fixed the other issue by changing the baud rate, here is the result for the set command.

I have a hunch ...
ASR 903 has three different type of RSP. The file "asr900rsp2-universalk9_npe.03.18.01.S.156-2.S1-std.bin" is for an ASR 903 with an RSP2. Can you please examine the router and determine if it indeed have an RSP2.
Now, if it is an ASR 903 with an RSP2, then try to download the latest 3.18.X train "asr900rsp2-universalk9_npe.03.18.07.SP.156-2.SP7-ext.bin" and see if router will boot that.

[adamcarter778373960]

That's fixed it!! You were completely right, the RSP I had was ASR903-RSP1. I have downloaded the correct IOS and booted from the usb in rommon mode and it works! Thank you very much!

Thanks for taking the time to give us the update. :)
That was fun troubleshooting.
