Hello David, wondering if you have or could do a video on changing link speeds and making them persistent.
Why is "manageability" showing a green upgrade sign ? How can I remove/upgrade it ?
That is not an upgrade, it means that there are on errors and the system is up.
Whenever we edit disk and expand, will there be data loss?
There shouldn't be. If you are worried about it, make sure you do a backup first. That is normally a good idea just incase something goes wrong anyway, but there shouldn't be any data loss.
