I'm having trouble upgrading our 3750 switches with LMS 2.5.1.
Firstly the job fails gaining 'full access' (Device is being locked for exclusive write access).
Then after the IOS is copied to flash the job time-outs eventually stating that it failed. But the file is actually there.
I suspect that the problem stems from not having full-access. All passwords and credentials have been checked. They also work fine in all other RME areas. A manual upgrade works too.
Does anyone know why this happens? Any comments would be appreciated :)
Change the order of protocols used for config & software management. I had the same trouble when using rcp. I use only TFTP & ssh (or telnet). Now it's fine.
