VMware max LUN size


we have a customer with a FAS8020 storage, ONTAP 9.3 and added recently a DS4246 shelf with 12x 4TB disks.


After creating a single aggregate with all 12 disks, it doesn't let me create a 20 TB LUN with VMware as host type,

cause of "Size out of limit. Maximum size for VMware can be 16TB"


Is this the maximum supported LUN size or am I doing something wrong?


Thanks for any reply,
