Environment

SDDC 5.x

vCenter 8.x

Cause

The VCF Brownfield process requires a standardized VMkernel configuration like 'VSAN', 'VMOTION', 'VXLAN', 'NFS', 'VSAN_EXTERNAL' or 'ISCSI' to ensure successful integration. 

Resolution

You must remove the  "vSphere Replication" or "vSphere Replication NFC" service from the VMkernel adapters on the all the hosts to proceed.

1. Identify the offending VMkernels

Log into vCenter and check all the host.

• Go to Configure > Networking > VMkernel adapters.

• Look for any adapter where the Enabled Services column includes "vSphere Replication" or "vSphere Replication NFC".

2. Disable the Service

• Select the adapter and click Edit.

• Uncheck both "vSphere Replication" and "vSphere Replication NFC".

• Note: This will temporarily pause replication for any VMs using this host, but it is necessary for the import to function.
