Discovery facts don't show machine's disks connected to raid controller

Problem:
Discovery facts don’t show machine’s disks connected to raid controller. In my case it is Lenovo raid controller based on Avago MegaRAID. Is it expected?
Expected outcome:
Disk count and size should be visible for disks connected through raid controllers without any additional fuss.
