Permission Problem if Host Had Been in Lockdown Mode
Details
You add a host to a VirtualCenter Datacenter or Cluster using the VI Client. As part of the Add Host operation, you choose Enable Lockdown Mode. If the VirtualCenter database is deleted after that operation, and you attempt to add the host to the VirtualCenter Server again, the following error message results:
Permission to perform this operation was denied.
Solution
Follow these steps to resolve the issue:
Open the direct console (DCIU) on the host.
