Skip Domain Resources Validation prior to NSX Deployment

Products

• VMware SDDC Manager / VCF Installer

Issue/Introduction

NSX Deployment on a domain fails on validation action: "Validate hosting Domain has enough Resources for NSX Deployment" but customer is aware that there are sufficient resources for this action.

Environment

VMware Cloud Foundation 5.2.x

Cause

When NSX is to be deployed on a domain, an explicit validation is to run with regards to the available resources on the domain as to whether or not they are sufficient. It flags the cluster's CPU, Memory and Storage if any of them are below the suggested values. This is a hard suggestion as per the preferences on NSX, eg. form factor, cluster size. However the customer may prefer to skip this hardbound validation. For instance, the computation for available resources will not take into account the powered off VMs and may inhibit a customer's demand for over-provisioning.

Resolution

1. SSH into the SDDC Manager with vcf user and then elevate to root with su.
   
   
2. Edit the domainmanager application-prod.properties file
   
   vi /etc/vmware/vcf/domainmanager/application-prod.properties
   
   
3. Add the following line to skip the resource validation. 
   
   nsx.domain.resources.validation.skip=true
