Symptoms:

   

   The Datastore is checked on the Datastore Configuration as a provider.
Still when "unlisted datastore can be used for all purposes"
The ZVM does not allow the disks to be used for pre-seed (volume are not listed on the ZVM)
     

 


Cause:

   

   The Datastore is not added to the ZVM on the Datastore "Provider Configuration window" correctly and it is not configured to be used by the ZVM for pre-seed disks.    

 


Solution:

       

From the ZVM on the Site settings:
Accessed from Site Settings > Cloud Settings tab > Datastore Configuration area

In the Provider vDCs area (top), click Add.
And Configure Provider > "Provider Datastore" you will specifically need to select the "pre-seed" possibility to that datastore from the available options: [mirror], [journal] and [pre-seed].
