Skip vSAN connectivity check validation in case of Isolated Multi DVS network configuration

Products

• VMware SDDC Manager
• VMware Cloud Foundation

Issue/Introduction

If the vSAN and Management traffic are in two separate isolated networks (Multi DVS), in the current implementation, the connectivity validation action fails. 

Environment

VMware Cloud Foundation 5.2.1.2

VMware Cloud Foundation 9.X

Cause

During validation, the vSwitch passed in the network specification is ignored and management vSwitch is being used to check connectivity.

Resolution

From SDDC Manager 5.2.1.2  and above, as a workaround, the validation can be skipped by updating the application.properties file of the domainmanager. 
Before proceeding, ensure that the network details provided in the input specification are correct and reachable. If the provided network detail in the input specification are incorrect, the workflow will fail at a later stage. 

1. Take a snapshot of the SDDC Manager appliance.
2. SSH to the SDDC manager appliance and switch to root:
   su - 
   
   
3. Open the following file "/etc/vmware/vcf/domainmanager/application.properties" in edit mode.
4. Add the following param to the file and set it true, "validation.disable.vsan.connectivity.check=true"
5. Save the file and restart the domain manager service using the following command "systemctl restart domainmanager"
