Issue/Introduction
- In a VCF environment, administrators may encounter a failure when attempting to add an ESXi host to an existing vSAN stretched cluster. "Add Host" workflow fails during the validation phase, preventing the expansion of the cluster across availability zones.
- Add host workflow reports the following error:
"Selected hosts do not match existing host network pool <pool2> in cluster."
- In the
/var/log/vmware/vcf/domainmanager/domainmanager.log, you may find entries similar to:
YYYY-MM-DDTHH:MM:SS DEBUG [vcf_dm,...] [InventoryServiceAdapterImpl] Fetching Cluster with ID ######################YYYY-MM-DDTHH:MM:SS DEBUG [vcf_dm,...] [ClustersPatchHandler] isStretched: false

Environment
VMware Cloud Foundation (VCF) 5.2.2
Cause
The issue is caused by an incorrect metadata flag in the SDDC Manager inventory database. Although the cluster is configured as a stretched cluster, the isStretched attribute for the cluster is set to false.
Resolution
If you encounter the symptoms outlined above, contact Broadcom Technical Support for further assistance, as the resolution involves modifying SDDC database instance, which should be performed with caution.
