MAAS caot detect hard disk

i just installed MAAS server and deploy the nodes using Multinode Quanta server. The storage is using LSI Megaraid Raid controller. I manage to commision and make the nodes ready. however, i notice that the Disk and Storage for all the nodes is keep showing 0 disk and 0GB. When i reboot the server, i can see that there is already virtual disk being configured using the LSI megaraid controller.

is there anyway and special step that i need to configure to make sure MAAS able to detect the disk? do i need to add any LSI raid driver ?

looking forward for advise on how to solve this.
