Dell PowerSwitch S4148U-ON with storage SC5020

Hi, I'm facing few problem to configure Dell PowerSwitch S4148U-ON with Dell storage SC5020. By following dell provided documents "Dell EMC Networking Fibre Channel Deployment with S4148U-ON in F_port Mode" I’ve done bellow steps * I’ve created zone with host and virtual WWPN of storage. * At storage manager I found the “operational mode is Virtual” and all virtual port if down. * No host initiator found. Then I’ve tried zone with host WWPN and Storage Physical WWPN. Now I found host initiator and storage. But virtual WWPN of storage is still down. I've created server and assign volume to that server but the connection is down (Showing at storage) and nothing found at host end. Anyone can help me regarding this issue?
