If the vSphere Replication appliance was deleted before you unregistered it form the environment , you cannot use the virtual appliance management interface (VAMI) to unregister vSphere Replication from vCenter Server.
Only a vSphere administrator can clean up the environment.
The procedures on removing the permissions for a solution user and on removing a solution user from the vCenter Single Sign-On domain are documented in the VMware vSphere 6.0 documentation center. See Remove Permissions and Delete vCenter Single Sign-On Solution Users.
Prerequisites
Verify that you know the credentials of a vSphere administrator.
Procedure
What to do next
You can deploy a new vSphere Replication appliance.
Note: If a
vSphere Replication appliance is deleted before all replications that it manages are stopped, target datastores remain tagged with the
com.vmware.vr.HasVrDisks tag. If a target datastore that is tagged with
com.vmware.vr.HasVrDisks is part of a datastore cluster where Storage DRS is enabled, some operations, like Enter maintenance mode, might not succeed when the
vSphere Replication Management server is missing. To prevent errors, you must remove the tags from all target datastores that were used for replications by the deleted
vSphere Replication appliance. See
Search and Remove the vSphere Replication Tag from Target Datastores.
