Issue/Introduction

If a cluster with less than 2 uplinks per vds is imported using the brownfield import tool, an error stating “Each hostSystemSpec must include a 'vmnicToVdsNameMap' with at least 2 unique vmnics.” will be encountered when trying to add a host to the cluster. 

This is a vcf requirement that will need to be addressed before the add host operation can be completed successfully

Environment

VCF 5.2

Resolution

1. Create a valid uplink in vsphere for those host that have less than 2 uplinks
2. Download the vcf-brownfield-import toolset onto the SDDC Manager VM open the directory via an SSH session
   cd /home/vcf/vcf-brownfield-import-x-y-z/vcf-brownfield-toolset
   
   
3. Run the vcf_brownfield.py script using the following command to sync the vCenter and SDDC Manager inventory.
   python3 vcf_brownfield.py sync --domain-name '<domain-name>' --local-admin-password '<password>'
