OS do not boot after restart, stucks F/W Intializing

Hi

I have Dell Server R740 EMC, i have RAID Controller H730P and i am trying to create RAID 5 with 4 SSDs.

I have successfully created RAID and also installed Windows Server 2016, now when I restarted my server, it stucks on F/W Initializing and takes long time to reach 100% and after that it does not find RAID controller and does not boot OS.

I Powered Off my server and again Powered it On then it finds RAID Controller and starts OS

All this story happens with SSDs but with SAS, it works completely fine

Any Suggestions?
