Cannot get 2nd 3750 upgraded in the stack

[JonB93]

I'm completely stuck and have been at this for hours.   I have a version mismatch, and need to get my 2nd switch upgraded to 15.x from 12.2.  I have the bin file on both flashes.   Flash and flash2.  I've tried the

boot system switch all flash:/insert_fileName_Here

and it still wont upgrade it.

When I do a sh boot, I never see the second switch like in the documentation here>  

Step 5 - Verify Before the Reload

Verify the boot variable:

Switch#show boot
BOOT path-list      : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin

!--- Primary switch.
Config file         : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break        : no
Manual Boot         : no
HELPER path-list    :
Auto upgrade        : yes
-------------------
Switch 1

!--- Member switch.
-------------------
BOOT path-list      : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin
Config file         : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break        : no
Manual Boot         : no
HELPER path-list    :

Any ideas on what I could be doing wrong?

Did you enable auto-upgrade ?  

(config)#software auto-upgrade enable

write mem

[JonB93]

That command doesnt appear to work on a 3750

I know what is going on here.  The 2nd unit have a different license level.  Since the "upgrade" method used was to "copy the IOS from one switch to another", the option to change the license level does not work. 

The only option, that I am aware of, is to use the recommended method, download the TAR file and use the command:  archive download-sw /allow-feature-upgrade

[JonB93]

Well, I dont have the tar file or access to it.   The switch when booted up tells me to run   archive copy-sw /force-reload /overwrite /dest 1 2

However, when I do that it says not enough space.  I think because its trying to package up a tar file and its huge.  In that case, not sure if its safe to remove the bin file from flash to free up space.

I doubt it.  The command "archive copy-sw" is not a valid command.  

The key here is /allow-feature-update.  WIthout this option, nothing matters.

Have you tried this article as far as the manual update? It's about halfway down.

[JonB93]

Yes, exactly as described and no luck.

Hi

 did you try to break up the stack, upgrade individually and join again?  

[JonB93]

I did that yesterday actually and that worked. Thank you!
