Cisco 3850 Flash Storage Issue

[Todd Wilson]

Ok @flavio thanks for sharing the information on uploading the .bin file to the 3850 but here's the current problem. Whenever I upload the .bin file via usb, tftp, then reload the switch it removes the .bin file from the "flash" storage. How can I be sure that I don't have an issue with my flash storage on this switch? Thanks in advance.

 wait a minute, are you saying that you transfer the IOS to switch´s flash and the switch is deleting the file on reload.

Can I see the output of "show flash:" ?

Please see the screenshots attached.

The switch is in Bundle mode. Convert it to install mode.

You are downloading the  cat3k_caa-universalk9ldpe.16.12.12.SPA.bin , I would go for standard IOS cat3k_caa-universalk9.16.12.12.SPA.bin

software expand file flash:cat3k_caa-universalk9.16.12.12.SPA.bin

Conf t
boot system switch all flash:packages.conf
end

write mem
reload

Thanks @Flavio Miranda I followed you information and it help my issue has been resolved, you the man. Note: for some reason this command shown below didn't work so I have to actually run another command to allow me to boot to system flash:packages.conf.
I will add the command later today as it is on my notepad on the laptop that was used to console into the switch.

software expand file flash:cat3k_caa-universalk9.16.12.12.SPA.bin

software expand file flash:cat3k_caa-universalk9.16.12.12.SPA.bin

Wait a second ... I think I've seen this before. 

Check the logs.  Is something spamming the logs with a facility event that starts with "%ISSU-0-SOFTWRE_INVALID" and the rest of the line talks about a missing binary?

Flavio's information fixed the issue thanks anyway.
