If the vSphere Replication appliance was deleted before you unregistered it from 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 vSphere 6.5 Security document. See topics Remove Permissions and Delete vCenter Single Sign-On Solution Users.
Verify that you know the credentials of a vSphere administrator.
- Log in to https://<vCenter_Server_address>/mob/?moid=ExtensionManager with vCenter Server credentials.
- In the extensionList property, click the link for the com.vmware.vcHms extension key to check the key details.
- Verify that the displayed data is for a vSphere Replication appliance that is already lost.
- In ExtensionManager, click unregisterExtension.
- Enter com.vmware.vcHms for the extension key value, and click Invoke Method.
- Verify that the result displays void and not an error message.
An error message might appear if the specified extension is not registered, or if an unexpected runtime error occurs.
- Close the window.
- Refresh the ExtensionManager page and verify that the extensionList entry does not include com.vmware.vcHms.
- Remove the permissions for the HMS solution user from all vCenter Server instances in the Single Sign-On domain.
- Remove the HMS solution user from the vCenter Single Sign-On domain.
