Products

• VMware SDDC Manager

Issue/Introduction

• Below red banner is observed on "Workload Domains" page of SDDC manager:
  
  Failed to fetch NSX information
  
  
• Below red banner is observed on "Management Domain" page:
  
  VCF version information call failed. Provided domain ID is invalid
  
  
• Attempt to create any NSX-T component is blocked as the task never gets started although there's no issue reported in validation.
  
  
• /var/log/vmware/vcf/domainmanager/domainmanager.log reports:
  
  Fetching vCenters data from inventory
Unhandled exception in WorkspaceOneBrokerConfigDriftCheck isConfigurationRealized for resource <resource id>.
com.vmware.evo.sddc.common.services.error.SddcManagerServicesIsException: Management vCenter Server Details Not Found.
......
Caused by: java.lang.NullPointerException: Cannot invoke "com.vmware.cloud.foundation.rest.commonsvcs.model.Vcenter$DomainTypeEnum.equals(Object)" because the return value of "com.vmware.cloud.foundation.rest.commonsvcs.model.Vcenter.getDomainType()" is null
  
  
• Notice "type" field is empty for workload vCenter checking with below command in SDDC manager command line:
  
  psql -h localhost -U postgres -d platform -c "select * from vcenter;"

Environment

VCF on vXrail 5.2.0 and 5.2.1

Cause

The "type" filed is for some reason missing for workload domain vCenter in Vxrail-based VCF environment which causes NullPointerException when loading the logical inventory in lcm and domainmanager.

Resolution

The missing "type" value needs to be manually inserted into SDDC manager database.
