Upgrade 2960S fails

[disturbedone]

I'm using CNA 6.1.0 to upgrade all our 2960S switches but about 5-6 fail. The same process using the same file has succeeded on 10-12 other 2960S without issue.

It attempts to upload the file then gives the error:

Failed to execute the command archive download-sw /overwrite /http iosFile

I need to reload the switch before I can attempt an upgrade again but subsequent upgrades also fail with the same issue.

Google isn't terribly helpful. Any ideas why this occurs and how to resolve it?

This is trying to upgrade from 15.0(1)SE3 to 15.0(2)SE6 for most but in one case it's 12.2(54)SG1 to 15.0(2)SE6.

I found this

and it helped. After deleting a folder of the current version I still was not able to use CNA to upgrade but using the CLI to upgrade worked.

I'd still like to know why it won't upgrade via CNA. Any ideas?

Use the CLI and a FTP or TFTP server?

As per my previous post

but using the CLI to upgrade worked.

I did the upgrade via CLI & FTP but my question is why does it fail via CNA (yet work via CLI) and what needs to be done to get it to work via CNA? It's easy to upgrade 25 switches via CNA as it's only a couple of clicks whereas to do everyone via CLI takes an hour of manual work.

archive download-sw /overwrite /http iosFile

If that's the actual CLI command CNA is trying to send to the switchen its obviously wrong as there should be a URL after the /http part - i.e. '/

http://10.1.1.1/c2960-lanbasek9-tar.150-2.SE7.tar'.

I have only used CNA a few times and wasn't too impressed with it, however I was trying to use it to monitor the switches and not upgrade them. I can see the advantage if you want to upgrade several..
