HELP: IOS Upgrade on Cisco 3850-48P-S From 16.3.6 To 16.3.7

[zeratul]

Hi All,

Need some help on an issue I encountered when I tried to upgrade the IOS of a Cisco 3850-48P-S. I realized that the way the I did it was wrong. Idid it on this sequence.

1. Downloaded the IOS to flash.

2. Upgrade the IOS using the command: 

request platform software package install switch all file ftp:cat3k_caa-universalk9.16.03.07.SPA.bin new auto-copy

3. Clean-up the flash using the command:

request platform software package clean switch all file flash:

After doing step 3, I realized that all the packages and .bin file for the 16.3.7 were gone.

Switch#dir flash:*.pkg
Directory of flash:/*.pkg

Directory of flash:/

1562509312 bytes total (432070656 bytes free)

Now, my upgrade could no longer rollback to because for some reason, the files that got deleted is still occupying the flash space. But is not appearing when you issue the "dir" command. And I am worried that the device would go to rommon if I reboot it.

Kindly advise how I could successfully upgrade the IOS to 16.3.7 from its current state.

Hi there,

I have done it before just like what you say

As the .bin file was gone ,Do not boot flash:packages.conf
You need to boot the flash file like flash:cat3k_caa-universalk9.16.03.07.SPA.conf

You can use command "more flash:packages.conf and more flash:cat3k_caa-universalk9.16.03.07.SPA.conf"  comparing what difference between them 

Thanks

Hi,

There is no "cat3k_caa-universalk9.16.03.07.SPA.conf". They all files pertaining to 16.3.7 were already deleted.

Hi,

Have you modified the Boot system? Also share the "Show flash: or Dir flash:: output.

Hi,

"40413 -rw- 4737 Mar 25 2019 19:40:04 +00:00 packages.conf"

This file is overwritten today and you may face issue after reboot the switch. I suggested to perform step 1 and Step 2 again. After setting the boot system again and restart the switch. The switch will boot with the latest version and after you can run step 3 command.

Regards,

Deepak Kumar

Hi Deepak,

Since I do not have enough space on my flash, can I do the upgrade directly from a USB? and may ask what the syntax is?

[Deepak Kumar · Accepted solution]

Hi,

Here is the complete guide from the Cisco. Choose an option as INSTALL Mode:
