we are using summit x450a-48t with exos 18.104.22.168, recently, we want to reinstall or set factory default to it, but it didn't work.
we used command 'unconfigure switch all' and reboot, but the old configuration is still there, we also confirmed there is no default.xsf there, so we don't know how this happened.
we also tried to upgrade exos to new version, we can successfully download and install image on secondary partition, but sadly after rebooting, the active image and configuration was still old, even we used command "use image partition secondary".
I don't know what's going on here. anybody can provide hint to solve the problem? Thanks in advance.
