C9300 not saving config after upgrade

[Jeffrey_233]

Hi All

Just got a pair of Cisco C9300 upgraded them to v.17.06.04
And after a reload it is not saving my config.
It doesn't give me any errors when saving and not issues if I do a full configuration.
after a reload it's back to being erased.
What am i missing?

 - Check this document https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/216850-configuration-register-equivalent-clis-i.html , and or make sure settings are not in place to ignore the startup configuration (e.g.)

post-show version full output.(is this managed by DNAC ?)

[MHM Cisco World]

how you save yout config 
copy run start or something else ?

[Georg Pauwen]

Hello,

there is a small chance that your flash does not have enough space. Try and clean the flash:

9300# request platform software package clean switch all file flash:

This will delete old/unused files from flash...

[Leo Laohoo]

Post the complete output to the command "sh romvar".

[Jeffrey_233]

Not using DNAC
When saving with : 'wr mem' or 'copy run start' makes no difference it does say 'Building configuration...' 
Cleaning the flash didn't help, but thanks for that i was looking for that cmd.

[balaji.bandi · Accepted solution]

I think this is the issue I guess due to that it's ignored. - have you checked show version reg

SWITCH_IGNORE_STARTUP_CFG=1  

Set the SWITCH_IGNORE_STARTUP_CFG parameter to 0.

switch' config t
Switch(config)# no system ignore startupconfig switch all
Switch(config)# end
Switch# write memory

Thank you, I've just tried this on a switch stack I'm having issues with and it worked. I'm curious, what could have triggered the switch to go into that mode initially, any clue?

follow this guide to change the ignore startup from 1 to 0

[Jeffrey_233]

[balaji.bandi]

thank you for sharing and appreciate the feedback

@Leo Laohoo - should get this credit - since he was the one who asked for that output - I was able to find what was wrong based on the output.
