I found an article that led me to do:

(parted) mkpart primary 0GB 16TB
(parted) print
Model: DROBO DroboPro (scsi)
Disk /dev/sdg: 17.6TB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system  Name     Flags
 1      1049kB  16.0TB  16.0TB               primary
