How to add Datastore Existing on vCenter or Host

[Nazrulamin]

Hi Everyone, good day,

Yesterday i just deploy new vCenter Server Appliance 6.7 and add 3 Host, but the host need to disconnect and remove from eventory vCenter, after the all finish on host, i want add host to vCenter backup but the error show datastore conflict with existing datacenter, on host just unmount and delete the datastore, my question it is possible add the datastore previous at host?

This usually happens when you remove a host from the inventory, and there's a VM in the vCenter Server's inventory which points to that host's datastore.

Please check the existing VMs on vCenter Server for connections to that datastore (e.g. an ISO image configured on a VM's virtual CD-ROM drive). Once all references have been removed, you should be able to add the host again.
