4.3.5.2. Storage DRS Limitations
The creation, deletion, or modification of storage pods is not possible in vCloud Director.

performed at the vSphere level.
Member datastore operations are not permissible in vCloud Director.
Do not enable Storage DRS for datastore clusters used with vCloud Director if vSphere hosts are pre-vSphere 5.1. This is not a supported configuration.
