I too am grappling with partitioning my new NVME discs. The documentation says open a call. I've worked with NetApp arrays since 2000 and I've never encountered all of the inaccessible documentation there exists today.
First, opening a call isn't as simple as it sounds. I've opened man a call which take weeks to get attended, until I start calling up the ladder.
Secondly, why is the documentation hidden from customers who pay NetApp Support. If you can send me other complicated procedures, why can't I partition my own drives?
Ok, got that off my chest now. But seriously, please reconsider why you are hiding documentation that, I believe should be open
