Disks
Click on disks and then press the assign disks button to give them a capacity and type.
Click on disks to add or remove from the storage group being edited.
Each hotspare disk should be at least as large as the smallest disk on the storage group, and must be empty.
Primary Disk Partitions
Select a partition template to use for the first disk. The partition templates available will depend on the OS selected and the disk type assigned.
Advanced Storage Groups and Partitions
Storage groups are logical volumes which can span multiple drives on a disk controller.
Choose the storage group's type, its size, and the partition template if available.
Choose hotspares for the storage group selected. Hotspares will be used in the event another disk in the storage group fails. Press done when completed.
