catalyst 9800 boot old version after upgrade

[mfradin]

hello

i tried to upgrade in "INSTALL" mode from 17.03.07 to 17.09.05
(I have no HA)

all seems to be ok during upgrade (see attached) , bootvar seems ok :
BOOT variable = bootflash:packages.conf,12;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x10

but 9800 reboots on old version

is it strange that the packages.conf is not changed during upgrade ?

thanks, Marc

        According to the setting of the boot variable you seem to have multiple versions of packages.conf
      this one end on ,12  ; could  you have dir bootflash:  check if there is a more recent  and or last version
      if so , set the boot variable accordingly and reload the controller again , 
               (the reply has been corrected , for the time being take attention to above part only)

As suggested check the config register first.

also i would like to see dir bootflash: or dir flash: all the files.

Also check the content of packages.conf

more bootflash:packages.conf  - this should be pointing to new IOS XE packages.

have you looked at the upgrade steps :

Post the complete output to the following command: 

dir bootflash:*.conf
more flash:packages.conf | begin rp_boot

I think I know what this bug is and I know the workaround.

Hello,
thanks for your replies

I  changed the register and reload but the problem is the same

BOOT variable = bootflash:packages.conf,12;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

    Considering the settings of the BOOT variable , please instead provide the output from
                      more flash:packages.conf,12 | in  rp_boot

Thanks for the output.  This is an easy fix. 

rename bootfash:packages.conf bootflash:packages.conf.bak
copy bootflash:C9800-L-universalk9_wlc.17.09.05.SPA.conf bootfash:packages.conf

And then reboot the WLC.

  @Leo Laohoo            I sustain your remarks, but I also see :
                           BOOT variable = bootflash:packages.conf,12;
               Then the boot variable should be set too simple bootflash:packages.conf too (without any version extension)

    I also see in a bin file there in there too ; it's flash is a bit messed up , possibly resulting from
    conversion between modes (install vs bundle)

If I remembered correctly, "12" translate to "attempt to boot 12 times before going to ROMMON".

Looks like Upgrade broken some where, below conf should be packages.conf

take the backup packages.conf or move to different name,

copy  C9800-L-universalk9_wlc.17.09.05.SPA.conf packages.conf ( and reload and test it)

This is a very well-known bug that has been in existence since IOS-XE version 16.X.X.

I've documented this behaviour (including the "fix" or workaround) in the Gotcha section.  

Cisco 3850: IOS-XE/Firmware Upgrade

This is also the bug I avoid hitting if my One-Hit-Wonder (NSFW) process is used.
