How to enable QLogic FC HBA interfaces in Centos 7

I’m facing an issue during the connection between QLogic FC HBA and Cisco Nexus SFP. I checked Cisco SFP is working fine. But I don’t know how can I enable QLogic FC HBA in Centos 7. It always shows “Linkdown”. Please guide me on how can I fix the issue. That would be a very great help for me.
