Oh man. Don’t get me started!
personally, I’m not a fan of using the GUI to create aggregates except in the extreme simple cases.
i had a system yesterday with 24xnvme and the GUI would have been fine.
however the other system I did has 36 x SATA (18 per controller) and 12xssd for storage pool.
i did not even try the GUI but I suspect it works not have done the right thing. I tried to use the aggregate auto-provision and that would have yielded two SATA aggregates with 3 raid groups each. Not necessary. Instead I used the cli to create an aggregate with 10 of the shared drives (from adp) with a max raid size of 17. I then added 24 disks and ontap does the right thing: as any remaining shared drives to the first raid group and then makes a second raid group of 17 whole disks. I end up with a larger solution.
bottom line, I feel the cli gives me more control when I need it.
I’m one of those people that very rarely uses the GUI …almost exclusive on the cli
