After creating a draft from an existing cluster, stale ESX host entries are seen for ESX hosts that have been previously removed from the cluster.
VCF 9.1.0
This is due to a known issue where the VCP host inventory cache is not fully cleared as part of the host removal workflow. These entries do not cause an impact and can be removed from the draft as needed.
Engineering is aware of this issue and is working to fix this issue in a future release.
Fixed By: VCF 9.1.1
