IOS boot sequence

[BigK]

Hello, 

My current router is running IOS version 17.06.01. I placed the new IOS 17.06.03 in Dir and changed the boot sequence to boot from .03. But any time it boots is start from .01 any suggestion to have the router use the upgraded version.

I already changed the boot sequence in boot-start-marker, but keept reversing to 

R01#sho run | i boot
boot-start-marker
boot system flash:c8000be-universalk9.17.06.01a.SPA.bin
boot system flash:c8000be-universalk9.17.06.03a.SPA.bin
boot-end-marker

R1#dir flash:
Directory of bootflash:/

25 -rw- 805465714 Feb 1 2023 11:01:03 -08:00 c8000be-universalk9.17.06.03a.SPA.bin
11 -rw- 804748616 Jan 1 2023 06:45:42 -08:00 c8000be-universalk9.17.06.01a.SPA.bin

R1#sho run | i boot
boot-start-marker
boot system flash:c8000be-universalk9.17.06.01a.SPA.bin
boot system flash:c8000be-universalk9.17.06.03a.SPA.binThanks

Thanks!

I am not clear about this output:

boot system flash:c8000be-universalk9.17.06.01a.SPA.bin
boot system flash:c8000be-universalk9.17.06.03a.SPA.bin

Is this output from after your config changes or from after a reboot?

Perhaps you can do this for us:

- make the config changes 

- post the commands you entered and any responses generated by the router

- post the output of sho run | i boot

- make sure that you have entered copy run start

- connect to the router console, reboot the router, post all output to the console during the boot process

- post the output of sho run | i boot

Hi,

You may want to put c8000be-universalk9.17.06.03a.SPA.bin above c8000be-universalk9.17.06.01a.SPA.bin.

When you add a new "boot system" line, it is placed below the existing "boot system" line. You will need to add the new line, delete the old line and re-add the old line as follows:

boot system flash:c8000be-universalk9.17.06.03a.SPA.bin

no boot system flash:c8000be-universalk9.17.06.01a.SPA.bin

boot system flash:c8000be-universalk9.17.06.01a.SPA.bin

Thanks

Thanks all for your assistance.

After reading cisco documentation. I changed my config to the following and that seems to do the trick. 

boot-start-marker
boot system flash bootflash:c8000be-universalk9.17.06.03a.SPA.bin
boot system flash:c8000be-universalk9.17.06.01a.SPA.bin
boot-end-marker

Thanks

Thanks for the update. So now it is correctly booting the new image?

[BigK]

Yes,

Thanks!

Glad to have confirmation that it is working. You might want to mark this discussion as solved so that other participants in the community would recognize that they might find a solution if they have a similar problem.
