U are a genius! that was exactly what i needed, I had already seen it but I had not understood it. After that all the vm's went back to their original names and i was able to boot vcenter.

Then i had another problem with the vds network. I had to reset the network configuration of all hosts from the ILO (with help from Creating a vSAN Cluster without a vCenter Server) and do the unicastagent thing again. Everything returned to normal.

Tthank you very much really!
