Do any of you know what the correct syntax is for the "firmwarecleaninstall"? 

it asks if I want to use USB  - yes

it asks for filename - I tried relative or absolute path to nos4.1.2ac on the USB, but the error message always is:


Do you want to continue (Y/N) [Y]: y

bootenv: Could not get requested variable submask.

The server is inaccessible or firmware path is invalid. Please make sure the server name or IP address, the user/password and the firmware path are valid.


does anyone know?

Re: firmwarecleaninstall

Firmwarecleaninstall is a root command hangover from FOS. The USB option fails on NOS but if you run firwarecleaninstall and respond to the prompts taking FTP as the option it can work.( will overwrite both partitions of flash)

So syntax wise answer no to using USB and follow prompts firmware download style from there pointing to unzipped NOS on an FTP server . Just check you login and path details to the image if it is not picked up.
