C9300 Cloud Managed Wont Save Startup Config

[CurtisV]

Thought id check with the community to see if anyone else has seen this. Currently working with support to identify why we have 1 network and switch that refuses to save the startup-config. If the device reboots, it comes up with factory defaults, minus firmware (17.15.4). Itll sync and apply changes to the running-config just fine. Not seeing any obvious issues in the logs.

Thanks!

Take a look at this.

C9300 not saving the config after a reboot – MAC me happy

I would suspect the switch might have the ignore startup config parameter enabled somehow:

Meraki support would have to manually run the command in that section to turn that back to normal.

Appreciate the response but I don't believe this is the issue. Issuing 'show start' from the cli terminal shows that the switch isn't saving the running config to begin with. It seems like whatever function is responsible for issuing 'write mem' (or some variation of it) after downloading and syncing the running config from the Meraki dashboard isn't working.

The question is, what did Meraki's support team tell you? I believe that if even they couldn't solve it, you'll hardly be able to solve it here.

The issue was escalated to the product team, and we're waiting for their feedback. Thought id post here to see if anyone else in the community experienced a similar issue or at the very least, share information on the issue.

It sounds like damaged flash memory to me.  I think you might be looking at an RMA.

[Brash]

Agreed this sounds like bad flash mem - although weird if it actually thinks it wrote the file successfully.

I'm not super familiar with what options you have when cloud managed, but are you able to attempt writing to a different file?

Eg. copy run flash:test
