Step 4. Specify Storage Resources
At the Storage Resources step of the wizard, specify destination datastores and datastore clusters where VM files will be stored. To do that, select the required resource groups in the list of available groups and click Add.
For a resource group to be displayed in the Available Groups list, it must belong to the hosts and clusters selected at the Compute Resources step.
To view datastores and datastore clusters included into a resource group, select the group and click View Resources.
