Hello All. I'am trying to configure cinder driver for vmax3 fc using the rest api driver. I am facing issues creating volumes from images because masking view errors: The error message received was Bad or unexpected response from the storage volume backend API: Error retrieving masking group On unisphere (8.4) log files I found that moveVolumeToStorageGroup is not found, while the openstack dell_emc rest-py is using it in its payload. Anyone could help us with this problem ? Regards Ignazio
