Hi, I have been playing with a NetApp disk on Linux and formattet it from 520 to 512... I have now installed this disk "by mistake" in a NetApp system, and it rightly so, reports "Unsupported" as container type..
But is there a way to format a disk inside ONTAP, in the node shell, or even if booting one of the nodes into maint. mode?

im going with no. cause why have code to use the drive for systems it's not ment for?

Well the disk is a standard X318 (8TB NL-SAS) and it's a very quick "fix" to use sg_format on Linux to format it with 512bps to be able to use it as a "normal" disk... I just forgot, or got one disk mixed up with the other 60 disks I added to a shelf in the datacenter... I was just hoping there was a way that I could save the travel to the datacenter by formatting the disks from ONTAP or some other way 😉

You might be able to go into maintenance mode and do it there. There is a form of SCSI format in there. Takes a while but it may work
I don’t know the commands off hand. I know I used them once upon a time

there is a SCSI format in maintenance mode (at least there was, at some point) but I don't think it can change the block size. It will just re-format with what the disk is currently formatted as

I’m not sure if it’s a reformat as is or reformat as ONTAP wants it. Not even sure what arguments are there

I ended up just replacing the disk... I will have a try in the lab later to see if it's possible...
