HP proliant DL160G6 - p410 raid controller problem

Hello.

I've a raid controller which is HP Smart Array P410. 

also I've four SATA3 HDDs(1TB * 2ea, 2TB * 2ea) which are all HGST.

I want to organize raid-10.  Fig 1 is my plan.

Fig 1. My plan

I've selected four disks for raid-10 (Fig 2).

 

Fig 2. Select four disks and raid-10 option.

However, only 1863.0GB is available(Fig 3).  I anticipate about 3TB disk size.  How can I solve the this problem?

 

Fig 3. Raid-10 disk capacity problem.

I'm alreay updated p410 raid controller firmware. (v3.0 -> v6.64) however, It still shows 1.8 TB disk size that consist of raid-10.

Fig 7 is Raid-5 setting using four disks. Is 3.00TB disk size(raid-5) correct?

Raid 1+0 is built using 4 drives of the same size. When you use dissimilar drives, it uses the smallest capacity common to all, so only 1GB is being used on the 2GB drives, so only 2GB available (less overhead).
