VMware SDDC Manager / VCF Installer

Issue/Introduction

VCF Installer while importing existing NSX Cluster fails during validation stage with an error that reads, NsxtCluster <nsx manager fqdn>: Validator 'nsx-import-vms-location-validator' failed internally
Remediation: Check the logs and if this issue persists contact VMware support.

Another error on similar validation check failure is reported as, NsxtCluster <nsx manager fqdn>: Failed to validate NSX Manager credentials due to internal error.
Remediation: Check the /var/log/vmware/vcf/operationsmanager/operationsmanager.log file for more information.

/var/log/vmware/vcf/operationsmanager/operationsmanager.log reports about the placement of the NSX manager virtual machine and states as an error.

Environment

VCF 9

Cause

The NSX VM is not colocated with vCenter, hence, the validation refers to those virtual machines that should be managed by the same vCenter that is involved during deployment and marks as an error failing the installer operation.

Resolution

For the import to be successful, the following constraints regarding the NSX Manager appliance VMs must be met:

The VMs for all nodes in the NSX Manager cluster must reside in one of two locations:

The specific vCenter Server instance that is being imported.
The VCF Management Domain vCenter Server.
