IR1101 boot issue

padraignotlad · ‎06-11-2021

Hello,

I was trying to downgrade the iOS on an IR1101 router from ir1101-universalk9.17.02.01.SPA.bin

to ir1101-universalk9.16.11.01.SPA.bin.

I accidentally entered "boot system flash:/ir1101-universalk9.16.11.01.SPA.bin"

When I should have entered "boot system bootflash:/ir1101-universalk9.16.11.01.SPA.bin"

Now the router is in a boot loop because it can't find "flash:"

I've been able to ctrl+c to break and enter rommon> and manually boot, and then when I'm in the OS, I try to fix with the correct boot statement, but it doesn't take.

I've tried changing the boot statement by using the set command, but that doesn't save either. Even when I type "sync" after.

How to I fix this? I just want to forget about downgrading and load ir1101-universalk9.17.02.01.SPA.bin.

Thanks,

Padraig

OmfG, 16.12.1 to 16.11.1! Downgrading from one buggy version to an EXTREMELY buggy version. That will go down well.

If you are in ROMMON, then enter the command "boot bootflash:ir1101-universalk9.16.11.01.SPA.bin". Once the router boots up into ROMMON make the necessary corrections to the incorrect boot-variable statement.

I can boot into the OS fine from rommon, but when I try to change the OS with "boot system bootflash:ir1101-universalk9.17.02.01.SPA.bin" and then "wr" and reload, it is still looking for flash instead of bootflash. When I initially downgraded, I accidentally typed "boot system flash:ir1101-universalk9.17.02.01.SPA.bin" when I should have used "bootflash".

Hello @padraignotlad ,

you need to delete the wrong statement because the new command boot ... does not replace the previous one. It is placed after it. IOS allows for multiple boot commands

You need to do

conf t

no boot system flash:ir1101-universalk9.17.02.01.SPA.bin

then do show run | inc boot and verify the wrong command has gone.

Finally save the configuration.

Hope to help

Giuseppe

If the boot variable statement is entered incorrect, the router will boot into ROMMON due to CSCvg37458.

The correct boot variable statement for routers running IOS-XE is:

boot system flash bootflash:filename.ext

For more information, read THIS.

Finally, booting into Bundle Mode is not recommended. Install Mode is the recommended method.

Thanks Guys ( Leo Laohoo and Gluseppe Larosa ) Using both commands together stopped the unwanted version from being loaded and loaded the desired version which solved the problem for me. It seems that starting in Ver. 17.02.01,Cisco added a feature in the GUI

under : Admin- Software Management-Software upgrade to remove inactive files which can clear up to 50 percent of the Bootflash

Directory .Which helps Performance.

Post the complete ROMMON output to the command "set" and "dir flash:".

dir flash didn't work but dev does:

rommon 6 > dev flash:
Devices in device table:
id name
bootflash: Internal flash drive
usbflash0: External USB drive 0
rommon 7 >

In ROMMON, try this:

boot bootflash:ir1101-universalk9.17.02.01r.SPA.bin

NOTE:

If "bootflash:" is not accepted, try "flash:".
If the router boots up, upgrade to a different version. Avoid using single-release IOS-XE versions. The latest 17.3.X is a good candidate.

That is the wrong syntax. It should be "dir bootflash:" (all lower caps). ROMMON is "sensitive" and very case sensitive.

If "dir bootflash:" does not work in ROMMON, try "dir flash:".

(Different platforms have different naming standards for "consistency" purposes.)

rommon 8 > flash:
monitor: command "flash:" not found

That is the wrong command.

dir flash:

I'm still having this problem. I can't change the configuration register, and I can't change the boot variable.
