Add the SCVMM server to the EFA Hyper-V Service instance. Do the following:
efa tenant create
                    command to create your tenant entry. When creating the tenant, ensure that you
                    provision an adequate number of VLANs that are available for use.
            efa inventory device
                        list command to do so. 
            This command will create a tenant entry that is used when registering a SCVMM server with EFA.
 This command creates a tenant entry with the name
                    scvmm-10.24.85.111. 
$ efa tenant create --name scvmm-10.24.85.111 --vlan-range 2-4096 --port 10.9.9.20[0/10],10.9.9.30[0/10] 
            
            Use this command to verify if the devices that you have added to the fabric are associated with the correct fabric.
