I’m a bit late in bringing this to your attention, but there is a potential issue with VASA storage providers disconnecting from vCenter resulting in no VSAN capabilities being visible when you try to create a VM Storage Policy. These storage providers (there is one on each ESXi host participating in the VSAN Cluster) provide out-of-band information about the underlying storage system, in this case VSAN. If there isn’t at least one of these providers on the ESXi hosts communicating to the SMS (Storage Monitoring Service) on vCenter, then vCenter will not be able to display any of the capabilities…
