I'm having a problem to merge two PvDCs, do not get the option in the UI (see attached figure). I have tried with the second PvDC completely empty and also in status disable. All Organization Virtual Datacenters are using the Pay-As-You-Go allocation model.
I tested one more thing, completely removed the second PvDC and tried to add the vSphere Cluster, to which the second PvDC was pointing, to the existing PvDC. During this test i could only select the vSphere resource pools within the vSphere Cluster to which the PvDC was already connected. My initial thought was permission but the accounts used to connect vCloud Director to vCenter Server and vCNS Manager to vCenter Server have the administrator role on the top vCenter Server level.
vCloud Director uses the latest build (vmware-vcloud-director-rhel-5.1.1-868405.x86_64 and vmware-vcloud-director-5.1.1-868405.x86_64 packages are installed), the vCenter Server runs 5.1.0 799731 and all the ESXi servers runs version 5.1.0 799733.
Any help appreciated.
