Backup fails with the error "<hostname> is not licensed for the backup feature". (4047904)

The VC and esx hosts are credentialed, license is applied to each host. Backup fails with the error "<hostname> is not licensed for the backup feature".

All ESX hosts and VC are in domain, DNS and Routing information is configured properly. All hosts are pingable by IP, short name, and FQDN.
ESX hosts are listed under short name in both VC and Ranger Inventory.
If VC is removed from Ranger inventory, all esx hosts are listed by FQDN, new backup jobs succeed.

The VC has the hosts added by the short name.  vRanger can not match ESX hosts listed under short name with host's FQDN.

We need to use the following VMware KB to correct the way the ESX hosts are presented in VC Inventory
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;amp;cmd=displayKC&amp;amp;externalId=1014030

To configure an ESX host to display the FQDN in the vCenter inventory:

1. Disconnect the ESX host from the Inventory in vCenter. Do not remove it from the Inventory.
2. Log in to the ESX host as root using an SSH client, ex. Putty. If login with an SSH client is not possible, log in to the physical console of the ESX host as user root.
3. Delete the vpxuser account with the command:
userdel vpxuser

Note: The vpxuser account facilitates communication between the ESX host and vCenter. It is created again when the ESX host is connected back to the vCenter.

4. Right-click on the ESX host in vCenter and choose Connect.

In vCenter Server 4.0 the following error displays:

Cannot complete due login due to an incorrect username or password

In vCenter Server 2.5 the tasks show the error:

Login failed due to a bad username or password

These messages can be safely ignored.

5. Enter the FQDN for the ESX host and login credentials for the root user to add the ESX host to the Inventory in vCenter using its FQDN.

=================

As soon as ESX hosts are displayed properly (with FQDN) in VC inventory, we can observe the same view in Ranger inventory and jobs succeed.
